Allsopp Laboratory


Telomeres are essential genetic elements that cap the ends of chromosomes. The replication of telomeres in proliferating cells is accomplished by a specialized ribonucleic acid enzymatic complex called telomerase. I have been studying telomere shortening and cell aging as well as telomerase biology, especially regulation of telomerase, for over a decade. More recently, as a post doctoral fellow in Dr. Irving Weissman’s lab at Stanford University, I became interested in stem cell biology, especially the regulation of telomerase in stem cells. I joined the Institute for Biogenesis Research (IBR) in the summer of 2003 as an assistant professor, where I am at present. My current research interests at the IBR are still in the area of stem cell biology and telomere/telomerase biology, and also include research on factors controlling and effecting long-term stem cell survival. I am particularly interested in figuring out how telomerase is regulated in stem cells, and what role telomerase dysregulation may have during perinatal development. I am also interested in the role that a new gene, Sirt1, may play in different types of stem cells. Sirt1 is an NAD-dependent protein deacetylase that effects both cell survival and has been implicated as a transcriptional regulator of telomerase as well. Stem cells which I am particularly interested in include blood stem cells, germ line stem cells and neuronal stem cells.

Alvarez Lab

Bachmann Lab


The Bachmann lab is located at the College of Pharmacy Department of Pharmaceutical Sciences at the University of Hawai‘i at Hilo. Research focuses primarily on a pediatric cancer called neuroblastoma. Molecular biology, cell biology and translational research is being conducted to elucidate new therapeutics and regimens for the treatment of relapsed patients with the goal to improve the currently low survival rates. Polyamine and proteasome inhibitors are investigated, and novel tumor promoting proteins (PRAF2) studied to better understand the underlying mechanisms which control tumor proliferation and metastasis. The Bachmann lab uses state-of-the-art new equipment to perform its research including the Perkin Elmer Operetta High Content Screening System with live cell capability as well as a 5 to 50 liter mammalian cell bioreactor to produce large protein quantities for downstream experimental analysis and protein crystallization. The Bachmann lab is an official member of the Neuroblastoma and Medulloblastoma Research Consortium (NMTRC) which conducts phase 1 and phase 2 clinical studies with neuroblastoma patients also using Dr. Bachmann's drug regimen. The lab also collaborates with several other U.S. and European laboratories to perform their research.

Bennett Lab


Dr. Bennett applies advanced technologies from genomics and bioinformatics to study dengue, hantavirus, influenza, and other viruses, and also bacteria such as leptospirosis and those found in mosquito vectors. She is especially interested in the nature of genetic mutations that give viruses the potential to cause epidemics or switch to new hosts.

Berestecky Monoclonal Development Laboratory


Kapiolani Community College is part of the University of Hawaii System.

Berry Laboratory


Research in the Berry lab is focused on selenoproteins, proteins containing the essential trace element, selenium, in the form of an unusual amino acid, selenocysteine. Most selenoproteins in higher organisms function either as antioxidants or in maintaining cellular redox balance. These functions explain the long-known antioxidant properties of selenium. In all selenoproteins whose functions are known, selenocysteine serves as the catalytic center of an enzyme, and its presence is required for optimal enzyme function.

6. MicroRNA regulation

Bursell Lab


Dr. Bursell has successfully developed instrumentation to noninvasively measure different aspects of ocular physiology including retinal blood flow, retinal vascular permeability and retinal leukostasis measurements. These technologies have also been used in clinical studies, and because these methodologies are common to both clinical and basic research, can facilitate the interpretation of clinical results. He has been a significant contributor, in collaboration with Dr. King and Dr. Aiello, in the translation of the protein kinase C inhibitor from bench top to clinical trial through research showing its significant impact on retinal physiology in both animal models and preliminary clinical studies. More recently, in collaboration with Dr. Feener, he has been investigating novel vitreal proteomes such as carbonic anhydrase, and characterizing their impact on retinal physiology and retinopathy development. Over the past 20 years he has conducted, or been a part of numerous clinical research studies. He is an internationally recognized authority in his field of research.

Callahan Lab


There are two research projects in Dr. Callahan's lab. In the first a filamentous cyanobacterium is used to study the molecular genetics of cellular differentiation and the generation of periodic patterns. The second project looks at the contributions of bacteria, both commensals and pathogens, to the health of corals.

Chang Lab


Malaria is a major cause of global morbidity and mortality in tropical countries and most notably among infants, young children and pregnant women in sub-Saharan Africa. Our long term goal is to develop a safe and effective blood stage vaccine directed against merozoite surface protein-1 (MSP1), a major coat protein of P. falciparum merozoites. This goal requires development of two essential components of a malaria vaccine, (i) the production of an optimally immunogenic antigen capable of inducing a protective immune response, and (ii) the identification of an immunostimulatory and non-toxic adjuvant formulation that may be combined with this antigen to generate protective immunity to falciparum malaria. Previous studies in this laboratory have focused on developing a baculovirus recombinant 42 kDa MSP1 C-terminal polypeptide which is highly immunogenic and induces protection in a non-human primate model of P. falciparum malaria. One of our current research objectives is to improve the protective immune response to a P. falciparum MSP1-based malaria vaccine by combining sequences located within MSP1 blocks 4, 16, and 17 to induce protective immune responses to multiple MSP1 epitopes. Our second research objective is to evaluate the ability of a series of well-defined immunomodulators to stimulate an immune response to MSP1 with in vitro and in vivo biological activities against P. falciparum blood stages. We hypothesize that a multi-epitope MSP1 antigen formulated with specific combinations of TLR (Toll-like receptor) and NOD (nucleotide-binding oligomerization domain-like receptor) agonists will be effective in inducing a protective immune response to P. falciparum infection.

Chow Lab

Church Lab


Church will investigate the linkages between microbial physiology and biogeochemical cycles, targeting the time and space dynamics of specific microbial groups that control transformations of carbon, nitrogen, and phosphorus. By merging rate measurements of organic matter production and consumption with molecular approaches to identify variability in gene expression, he seeks to elucidate how the activities, biomass, and diversity of functionally important groups of organisms contribute to biogeochemical variability in the oceans.

Collier Lab


Originally from New Zealand, Dr. Collier received her B.Sc. in Pharmacology from the University of Auckland (1998) and her PhD in Pharmacology from the same institution in 2003. Dr. Collier teaches Pharmacology to undergraduate and graduate students as well as Clinical Pharmacology for medical students and was awarded the University of Hawaii Regent’s Medal for Teaching in 2011. Within Pharmacology, her sub-specialty is drug metabolism and pharmacokinetics, primarily of the phase II (conjugation) enzymes, focused on pregnancy and pediatrics. A winner of the 2011 SimCYP award for Most Informative Report (“in recognition of scientific research that is leading the world in ADME, IVIVE, pharmacokinetics, modeling and simulation”), Dr. Collier uses a combination of wet laboratory work and in silico modeling to provide greater understanding of developmental pharmacology and improve drug/chemical safety. Dr. Collier’s research laboratory has been continuously funded by the National Institutes of Health, and private foundations since 2007. Along with her collaborators, she also performs research and publishes regularly in the fields of human and environmental toxicology and in endocrinology.

Couvillon Lab


Our primary interest is in learning and the evolution of intelligence. We work mostly with honeybees, whose performance in a wide range of learning situations proves to be closely similar to that of vertebrates despite the remoteness of the evolutionary relationship and the vast differences in brain size and organization; broad functional convergence is indicated. In work with pigeons and fish, our primary concern is with the development of quantitative theories of learning that permit exact rather than merely ordinal predictions of experimental outcomes.

Donachie Lab


Dr. Donarchie investigates the diversity and role of microorganisms in the environment, focusing on both prokaryotes and eukaryotes in terrestrial and marine systems. Current projects explore potential relationships between bacteria (Archaea and Bacteria) and endemic Hawaiian marine invertebrates, Hawaiian marine Fungi and yeasts as sources of novel secondary metabolites, and biogeochemistry in Hawaiian lava tubes.

Ernst Lab


Dr. Ernst is a Professor at the JABSOM in the Dept. of Medicine, UH and an MR Physicist with extensive experience in the application of advanced MR techniques to clinical research in various brain disorders, especially in the areas of HIV and substance abuse.

Gates Lab


Dr. Ruth Gates and her group focus their research on coral reefs, marine ecosystems that protect coastlines, support tourism and provide nutrition to many island nations. The global deterioration in the quality of these ecosystems has been widely reported over the last 40 years, reflecting the complex interaction between climate change stressors (thermal anomalies, ocean acidification and storms) and chronic or acute local impacts (coastal development, pollution and over-fishing). Although the future looks bleak, some corals survive, and even thrive in the same conditions that rapidly kill others. Our group seeks to better understand the biological underpinnings of this variability by defining traits that associate with environmental sensitivity and resistance in corals, and with the resilience (capacity to recover) of reefs. Our goal in conducting this research is to contribute basic and applied scientific knowledge that expands understanding of how coral reefs function, and informs the management and conservation of these beautiful but threatened ecosystems.

This lab also has an Experimental Manipulation Facility, which allows researchers to create climate change conditions (e.g. temperature, CO2, capacity for delta light & delta flow) in order to explore Marine living.

Genetic Sequencing Lab


We use molecular approaches to conducted research addressing issues on the systematics of the native Hawaiian flora. Studies involve phylogenetic questions of species biogeography in the islands both in terms of from where they came from and how they are distributing among the islands. Studies utilize molecular markers to answer these questions, and the type of markers will depend upon the specific question being asked. Also of importance in studying plants, especially in Hawaii, is the consequences of small population sizes. Hawaii is the "Endangered Species Capital of the United State" with over 300 endangered plant species and many others that are "species of concern" by the US Fish & Wildlife Service. As such, the opportunities to examine rare plant population genetics from many different perspectives are incredible.

Gerschenson Lab


Research in Dr. Gerschenson’s lab studies mitochondria in human cells and tissues. We are interested in adult and pediatric metabolic diseases (HIV and non-HIV insulin resistance, diabetes, obesity, fat, muscle, and liver tissue), neurological diseases (HIV peripheral neuropathy and HIV associated dementia), immunological diseases, and cancer. We conduct local, national, international clinical studies to obtain blood, cheek cells, fat tissue, urine, and cerebrospinal fluid, etc. to study mitochondrial genetics, energy metabolism, oxidative stress, cell death. We are also interested in how cytokines regulate mitochondrial genes via transcription and cell signaling.

Ha Laboratory


Dr. Ha's research focuses on biochemistry and minority education.

Hawaii Undersea Research Laboratory


The Hawai'i Undersea Research Laboratory is the only U.S. deep submergence facility in the Pacific Rim tasked with supporting undersea research necessary to fulfill the mission, goals, and objectives of the National Oceanic and Atmospheric Administration (NOAA), along with other national interests of importance. Over 30 years of submersible operations have resulted in nearly 1900 dives representing 9300 hours underwater, and a benthic ecology database derived from in-house video record logging of over 125,000 entries based on 1100 unique deep-sea animal identifications in the Hawaiian Archipelago. With emerging interest in marine resources of the Pacific and renewable energy from the sea, HURL's contributions will continue to play an essential role in scientific research and advanced technology. HURL was established by Cooperative Agreement in 1980 between NOAA and the University of Hawai‘i, at which point it became a Regional Center in NOAA's Undersea Research Program (NURP). In 2009, President Obama signed Public Law 111-11 authorizing both NURP and Ocean Exploration (OE), and their administration under a merged program called the Office of Ocean Exploration and Research (OER). The Center supports highly-rated, peer-reviewed proposals to conduct undersea research in offshore and nearshore waters of the main and Northwestern Hawaiian Islands and waters of the central, southern, and western Pacific, including the new marine national monuments. In addition, HURL accepts funded requests from private, state, or federal agencies and participates in international collaborative research projects.

Hernandez Lab


Dr. Hernandez's research focuses on infection and cancer. Viruses associated with human cancers include human papillomavirus (HPV), hepatitis B and C, Epstein-Barr virus, human herpesvirus 8, and Kaposi's sarcoma. These infectious agents influence the development of cancer through varied mechanisms including interaction of viral genes with host tumor-suppressor genes, integration of virus into host DNA, and the establishment of persistent or latent infections. Understanding the role of host response to infection is also key to elucidating the mechanism of viral carcinogenesis.

Hui Lab


Dr. Hui's research is based on the development of blood stage malaria vaccines; and studies on the use of different vaccine adjuvants for the malaria vaccines. Specifically, his focus is on the design of vaccines based on the Merozoite Surface Protein 1 (MSP1) by defining critical T and B epitopes of the molecule. His lab also evaluates the use of a variety of immunological adjuvants to enhance vaccine potency and at the same time define the critical pathway for adjuvants’ mode of action. The approaches also study the use of nanoparticle platforms for antigen delivery.

Imrie Laboratory

Jameson Lab


Our laboratory utilizes fluorescence methodologies to elucidate dynamic aspects of biomolecules. We are currently studying dynamin, a large (98kDa) GTPase which functions to “pinch-off” membrane vesicles in pathways such as receptor mediated endocytosis and synaptic vesicle recycling. We carry out both in vitro and in vivo studies on the self-association modes of dynamin as well as its interaction with membranes and other proteins such as endophilin and Arc/Arg3.1. We have also been studying dynamins with mutations that cause motor disorders, specifically Centronuclear Myopathy and Charcot-Marie-Tooth disease. These studies, both in vitro and in living cells, are aimed at understanding the molecular basis for dynamin’s involvement in these disorders. Recently, we began a project to study, both in vitro and in vivo, the self-assembly of the protein Leucine Rich Repeat Kinase 2 or LRRK2. Mutations in the gene for LRRK2 are responsible for an autosomal dominant form of Parkinson’s Disease (PD). We also have a project on Botulinum Neurotoxin which involves biophysical studies on proteins forming the neurotoxin complex as well as development of in vitro and in vivo toxin assays based on Fluorescence Fluctuation Spectroscopy. Recently we have been developing the application of the phasor method, a visual approach to treatment of time-resolved fluorescence data, to in vitro systems such as intrinsic protein fluorescence.

His clinical interest is in behavioral assessment for clinical case formulation.

Kolonel Lab


Dr. Kolonel's research focuses on the understanding the striking variations in cancer incidence and survival that are observed among the several different ethnic populations in Hawai‘i.

Kumashiro Lab


Current research projects focus on elastin, a vertebrate protein with remarkable biomechanical properties. The elastic properties of a number of physiological structures, such as blood vessels and skin, are believed to originate from elastin, an amorphous, crosslinked protein comprised largely of small hydrophobic amino acids. The three-dimensional structures of insoluble elastin remains elusive, as crystallographic tools and even the most sophisticated solution NMR spectroscopy cannot be used to study this insoluble protein. Therefore, for many years, the true nature of elasticity in biological systems has remained controversial, as none of the existing models could be confirmed or rebutted with high-resolution structural data.

Laboratory for Microbial Oceanography


The Laboratory for Microbial Oceanography is a research unit within the School of Ocean and Earth Science and Technology (SOEST) at the University of Hawaii at Manoa.

The Laboratory for Microbial Oceanography conducts basic research on microbial inhabitants of the sea, including bacteria, protozoans and unicellular algae.

The techniques we use include Atomic Force Microscopy (AFM), Langmuir-Blodgett (LB) technique, and drop shape analysis. The goal of our study is to explore the fundamental nature of biocolloids and biointerfaces, and to apply this knowledge to biomedical and clinical practices through an interdisciplinary and translational approach.

Lau Lab


Dr. Lau's laboratory is currently focused on the regulation of gap junctions by tyrosine protein kinases and novel, interacting cellular proteins. Gap junctions are one of four major types of intercellular junctions that are involved in establishing intercellular adhesion and communication. Gap junctions are unique because they enable the direct interchange of small molecules (<1000 daltons) between the cytoplasms of adjacent cells. This activity provides a form of intercellular signaling that is essential for the proper functioning of a variety of normal tissues.

Le Saux Lab


Calcification of cardiovascular tissues occurs in a variety of pathological conditions, including vascular injury, renal failure, diabetes mellitus, atherosclerosis, and aging. Mineralization is multifactorial and results from abormal changes in the balance between activators and inhibitors of calcification. We and others have established a link between ABCC6 and the chronic calcification of pseudoxanthoma elasticum (PXE) in human and the dystrophic cardiac calcification phenotype (DCC) in mice. ABCC6 is primarily expressed in liver and the kidneys but not in connective tissues. Therefore, we use various mice models to elucidate the characteristics of this novel mineralization inhibitor pathway.

Members of MarVEL are affiliated with the Center for Microbial Oceanography - Research and Education (C-MORE), and the Hawaii Ocean Observing System (HiOOS). Some of our previous work was carried out in affiliation with the Pacific Research Center for Marine Biomedicine (PRCMB).

Martindale Lab


We are interested in a broad range of problems associated with the cellular, molecular, and evolutionary basis of biological pattern formation. My lab utilizes a variety of molecular and "classical" techniques of microinjection, cell labeling, ablation, and transplantation, to address fundamental problems in developmental biology in a broad phylogenetic context.

My lab is currently focused in three major areas. The first area of interest is to understand the role of the early cleavage program in the segregation of developmental potential in a wide variety of animals which share a mode of embryogenesis known as spiral cleavage (e.g., molluscs, annelids, nemerteans, sipunculids, echiurans, and polyclad flatworms). Of particular interest is the mechanism by which dorsoventral polarity is established in members of different spiralian phyla. We are also interested in understanding the origins and significance of naturally evolved variations in the spiral cleavage program, such as modifications associated with the abandonment of larval development in order to develop directly to a miniature adult form (i.e., direct development). We consistently use intracellular cell lineage labeling and cell ablation techniques in a wide variety of species for many of our experiments.

The second area of interest is gaining an understanding of the relationship between radially symmetrical and bilaterally symmetrical metazoans. Current theory predicts that bilaterians are derived from a radially symmetrical stock, yet there is little evidence for how such a transition might have occurred. For example, what is the relationship of the oral-aboral axis of radially symmetrical forms to the anterior-posterior of bilaterians? How did the dorsoventral axis arise? Is there evidence for the origins of major cleavage patterns in bilaterian development (e.g., spiral and radial cleavage) in radially symmetrical forms? To what degree are the molecular events underlying morphological patterning and cell type specification conserved in this group of animals? We are investigating these and other aspects of early development in representatives of both anthozoan cnidarian and ctenophore embryos.

The third area of focus is to understand the evolution of biological novelties. These include the origins of the "middle" germ layer (mesoderm), the evolution of the nervous system in the Metazoa, and the evolution of unique cell types (cnidocytes, colloblasts, sensory cells, etc.). Many of these studies utilize cnidarians (the starlet sea anemone Nematostella vectensis) and ctenophores (the lobate Mnemiopsis leidyi), both of whose genomes have been sequenced. We continue to developed functional techniques to uncover conserved and novel molecular mechanisms underlying novel cell type formation.

Mau Laboratory

Moisyadi Lab

Monika Ward Lab


Assisted reproduction enables achieving fertilization when normal conception does not occur due to a variety of gamete defects. Intracytoplasmic sperm injection (ICSI) is the injection of a single spermatozoon directly into the cytoplasm of an oocyte using an injection pipette. This technique has been applied successfully in the treatment of infertile couples and is now widely used as a method of human assisted reproduction (ART). In addition to its obvious role in overcoming the infertility, ICSI is also an excellent tool allowing exploring new venues of reproductive biology. It provides a unique opportunity to examine the mechanisms underlying male infertility by looking into the reproductive potentials of individual spermatozoa.

The primary research interest of the lab is to study sperm genetics and function in fertilization in the context of assisted reproduction, utilizing advanced techniques of gamete and embryo micromanipulation combined with cytogenetic and molecular biology techniques, in a mouse model. The overall goal is to explore how the 'genetic composition' of sperm translates on its function in fertilization.

The ongoing projects involve:

(1) Reproducing subfertile and infertile mice with phenotypes that mimic various human male infertility syndromes to test for ART effects;
(2) Studying sperm DNA damage, its origin and consequences for fertilization and embryo development;
(3) Examining the function of the Y chromosome encoded genes in male fertility.

Our current work is focused on determining how expression of cancer-associated genes c-myc and p53 affects sensitivity to TNF and FasL induced programmed cell death in cell lines representing various stages on the pathway to cancer. We are also using our cell lineages to determine whether activation of caspase-2 plays a role in the differential sensitivity of cells to TNF- and FasL-mediated cytotoxicity. In addition, studies are underway to characterize TNF- and FasL-induced changes in mitochondrial membranes. This involves monitor the appearance of mitochondrial-associated proteins involved programmed cell death such as caspase-2, caspase-9, cytochrome c, and apoptosis Inducing factor.

Using a variety of approaches (genomics, molecular biology, microbial oceanography, and traditional microbiology), research in the Rappé Lab focuses on the diversity, evolutionary history, ecology, and physiology of microorganisms that inhabit coastal and open ocean seawater, corals and coral reef environments, and the deep subsurface biosphere.

Retrovirology Research Laboratory

Robinow Lab


My laboratory studies the genetic and hormonal regulation of nervous system development in the fruit fly Drosophila melanogaster. We are particularly interested in understanding how developmental signals such as hormones, nuclear receptors, trophic factors and synaptic contacts regulate gene expression to control nervous system development and function.

One project in the lab focuses on the regulation of programmed cell death, or apoptosis, in the nervous system. In Drosophila, the genes reaper, grim and head involution defective (hid) induce apoptosis when expressed at high levels. We have identified two distinct sets of neurons that die by apoptosis shortly after the emergence of the adult from the pupal case at the conclusion of metamorphosis, in a low steroid hormone environment. Both sets of neurons accumulate reaper and grim transcripts, but not hid transcripts immediately prior to their death. Application of the biologically active steroid 20-hydroxyecdysone prevents transcription of these genes and prevents the death of these neurons. We have identified a genomic region that regulates expression of the grim gene that is sensitive to the titer of 20E. We are currently characterizing this region to determine the mechanism by which 20E represses transcription of this gene.

The steroid hormone 20E drives Drosophila development by interacting with nuclear receptors that act as ligand regulated transcription factors. To define the cellular mechanisms and interactions involved in nuclear receptor signaling, we are currently conducting a screen to identify genes that are involved in nuclear receptor signaling pathways. This screen is designed to identify genes that function during metamorphosis when the animal undergoes a dramatic reorganization. Characterization of genes identified in this screen will help define the molecular pathways that are regulated by hormones during development.

Verma Laboratory


Dr. Verma’s long-term research goal is to understand immunological events associated with pathogenesis of neurotropic viruses to ultimately design therapeutic interventions and/or adjunct therapies to improve disease pathology. Her research employs both, in vitro and in vivo mouse models to delineate various innate immune signaling pathways that contribute to antiviral defense and inflammation in flavivirus infections. The focus of her COBRE project is to analyze mechanisms associated with disruption of the blood-brain barrier and its consequence with respect to the entry of West Nile virus (WNV) in the mice brain. In addition, ongoing studies are investigating the efficacy of anti-inflammatory drugs such as inhibitors of matrix metalloproteinases and cyclooxygenase-2 signaling pathway as a potential therapeutic target to manage WNV encephalitis. Another area of her research is to understand the role of NLR family of pathogen recognition receptors, NLRP3, NLRC5 and inflammasome adapter molecule ASC in modulating innate and adaptive immune response to WNV. One of her recent project also involves characterizing the role of epigenetic modulation in innate immune responses to flaviviruses.

Our research is focused on the structure of mammalian sperm chromatin and how this is related to function. The main hypothesis that we have tested is that the sperm cell provided the newly developing embryo with more than just the genetic code in the DNA sequence; it also provides a three dimensional organization of the DNA that provides crucial information as to how to use the father's genetic code.

DNA is packaged very densely in the sperm nucleus in a manner that is different from any other cell type. Most of the histones are replaced by protamines, and the DNA is crystallized into dense toroids with roughly 50,000 bp of DNA, each. Protamine condensation protects the sperm DNA from damage from external insults, and prevents transcription or DNA replication from occurring. We have shown that one structural feature present in all other somatic cells is also retained in sperm chromatin: the organization of DNA into loop domains attached at their bases to the nuclear matrix. This organization is crucial to two aspects of sperm chromatin function. Shortly after fertilization, the protamines are removed from the sperm DNA and the chromatin is repackaged with histones. The DNA is then replicated, and we have demonstrated that this DNA synthesis requires the loop domain organization to be intact. On the other hand, spermatozoa have the ability to digest their own DNA through an apoptotic-like process in which the sperm DNA is degraded. This degradation occurs on the nuclear matrix.

Our current research efforts are focused on understanding how sperm chromatin structure is related to the events that occur shortly after fertilization and how the DNA packaging in the sperm cell contributes to embryonic development.

Williams Laboratory


The research interests of Dr. Williams center on the discovery and evaluation of these small molecule chemical defenses from marine sources as potential drug leads. In collaboration with the other members of the Cancer Biology Program, marine extracts are screened against a variety of relevant cancer targets. The active constituents are then isolated using a combination of bioassay data and repeated separations. The structures of these metabolites are then determined primarily through the use of high-field NMR spectroscopy and chemical degradation. For example, Dr. Williams and colleagues have recently begun searching for novel inhibitors of the Ras/ERK MAP kinase pathway. Constitutive activation of this pathway is commonly observed approximately 30% of all tumor types and in 90% of all pancreatic tumors in epithelial tumors, hence it represents a potential therapeutic target. To this end, they have begun assaying extracts derived from marine sponges and cyanobacteria in an effort to discover new structural classes of inhibitors. Efforts in the Williams lab are directed towards identifying and characterizing these active components.
