The research interests of the Liu Lab are in functional proteomics and biopharmaceuticals. Currently we are working on the following projects:  (1). Using systems biology approaches to decipher the signaling pathways mediated by disease-related proteases such as caspases and granzymes and by post-translationally modified histones. We address these problems by performing functional protein selections using mRNA-displayed proteome libraries from human, mouse, Drosophila, and C. elegans. (2). Developing novel protein therapeutics and nucleic acid therapeutics that can be used in tumor diagnosis, treatment, and nanomedicine. We use various amplification-based molecular evolution approaches such as mRNA-display and in vivo SELEX to develop novel single domain antibody mimics on the basis of very stable protein domains or to generate aptamers on the basis of nuclease-resistant nucleic acids, that bind to important biomarkers on the surface of cancer cells. We further conjugate these biomarker-binding affinity reagents to small molecule drugs or nanoparticles for targeted delivery of therapeutic agents. (3). Identifying the protein targets of drugs or drug candidates whose action mechanisms are unknown. We combine molecular proteomic and chemical biology approaches to identify the protein targets of drugs whose target-binding affinities are modest.

The overall goal of our research is to develop an enzyme-based approach to synthesize heparin- and heparan sulfate-like therapeutics.  The lab is currently focusing on improving the anticoagulant efficacy of heparin drug as well as synthesizing heparin-like compounds that inhibit herpes simplex virus infections.  We are also interested in using protein and metabolic engineering approaches for preparing polysaccharides with unique biological functions.

RESEARCH INTEREST
Biochemistry, Biophysics, Cell Biology, Chemical Biology, Drug Discovery

We are a comprehensive, collaborative group with a primary focus on lead and early drug discovery for oncology and epigenetic targets and pathways. Our research applies reagent production, primary assay development, high-throughput screening, biophysics, and exploratory cell biology to enable small molecule drug discovery programs in solid partnership with collaborators, both within the Center for Integrative Chemical Biology and Drug Discovery and across the UNC campus. We apply small molecule hit discovery to highly validated biochemical targets as well as phenotypic cell-based assays. Our methods include various fluorescence-based readouts and high content microscopy. Examples of some of our collaborative small molecule discovery programs include, inhibition of chromatin methyl-lysine reader proteins, hit discovery for small GTPases such as K-Ras and Gaq, inhibitors of inositol phosphate kinases, inhibitors of protein-protein interactions involving CIB1 and MAGE proteins, and several cell-based efforts including a screen for compounds that enhance c-Myc degradation in pancreatic cancer cells. In addition, we are developing a DNA-encoded library approach for hit discovery to complement traditional high-throughput screening. Our ultimate goal is discovery of new chemical probes and medicines for exploratory biology and unmet medical needs, respectively.

The McGinty lab uses structural biology, protein chemistry, biochemistry, and proteomics to study epigenetic signaling through chromatin in health and disease. Chromatin displays an extraordinary diversity of chemical modifications that choreograph gene expression, DNA replication, and DNA repair – misregeulation of which leads to human diseases, especially cancer. We prepare designer chromatin containing specific combinations of histone post-translational modifications. When paired with X-ray crystallography and cryo-electron microscopy, this allows us to interrogate mechanisms underlying epigenetic signaling at atomic resolution.

We are interested in modulating the activity of chromatin reader proteins with small-molecule ligands, specifically potent and selective chemical probes, in order to open new avenues of research in the field of epigenetics. Our work has pioneered the biochemical assays and medicinal chemistry strategies for high quality probe development for methyl-lysine (Kme) reader proteins, as well as the means by which to evaluate probe selectivity, mechanism of action, and cellular activity. Using a variety of approaches, we utilize such chemical tools to improve our understanding of their molecular targets and the broader biological consequences of modulating these targets in cells. We are also interested in developing novel methods and screening platforms to discover hit compounds to accelerate Kme reader probe discovery, such as affinity-based combinatorial strategies, as well as innovative techniques utilizing our developed antagonists to more fully understand the dynamic nature of chromatin regulation.

Research in the Bowers lab focuses on investigation of structure activity relationships and mechanisms of action of natural product-derived small molecule therapeutics. We employ a variety of methods to build and modify compounds of interest, including manipulation of natural product biosynthesis, chemical synthesis, and semi-synthesis. One major area of research in the lab is the rationale engineering of biosynthetic pathways to make bacterial drug factories. Compounds targeting transcriptional regulation of cancer as well as multi-drug resistant venereal infections are currently under investigation in the lab.

The Jarstfer lab uses an interdisciplinary approach to solve biological problems that are germane to human health.   Currently we are investigating the structure of the enzyme telomerase, we are developing small-molecules that target the telomere for drug discovery and chemical biology purposes, and we are investigating the signals that communicate the telomere state to the cell in order to control cellular immortality. We are also engaged in a drug/chemical tool discovery project to identify small molecules that control complex social behavior in mammals.  Techniques include standard molecular biology and biochemistry of DNA, RNA, and proteins, occasional organic synthesis, and high throughput screening.

We focus on a variety of design goals including the creation of novel protein-protein interactions, protein structures, vaccine antigens and light activatable protein switches. Central to all of our projects is the Rosetta program for protein modeling. In collaboration with developers from a variety of universities, we are continually adding new features to Rosetta as well as testing it on new problems.
