PHD PROGRAM RESEARCH INTEREST |
In my lab, we are exploring the roles that kinases play in neurodegeneration through the creation of high-quality, small molecule tools. Our team designs, synthesizes, and evaluates small molecules capable of kinase modulation, sometimes targeting kinase inhibition and sometimes kinase activation. In order to accomplish our aims, we work closely with X-ray crystallographers within the larger SGC and with biologists, including experts in using stem cells to model neurodegenerative diseases. We seek enthusiastic students with an interest in neuroscience who are willing to learn and apply techniques that span chemistry and biology to better understand and address neurodegeneration. |

Antiretroviral therapy (ART) is effective in suppressing HIV-1 replication in the periphery, however, it fails to eradicate HIV-1 reservoirs in patients. The main barrier for HIV cure is the latent HIV-1, hiding inside the immune cells where no or very low level of viral particles are made. This prevents our immune system to recognize the latent reservoirs to clear the infection. The main goal of my laboratory is to discover the molecular mechanisms how HIV-1 achieves its latent state and to translate our understanding of HIV latency into therapeutic intervention. Several research programs are undertaking in my lab with a focus of epigenetic regulation of HIV latency, including molecular mechanisms of HIV replication and latency establishment, host-virus interaction, innate immune response to viral infection, and the role of microbiome in the gut health. Extensive in vitro HIV latency models, ex vivo patient latency models, and in vivo patient and rhesus macaque models of AIDS are carried out in my lab. Multiple tools are applied in our studies, including RNA-seq, proteomics, metabolomics, highly sensitive digital droplet PCR and tissue RNA/DNAscope, digital ELISA, and modern and traditional molecular biological and biochemical techniques. We are also very interested in how non-CD4 expression cells in the Central Nervous System (CNS) get infected by HIV-1, how the unique interaction among HIV-1, immune cells, vascular cells, and neuron cells contributes to the initial seeding of latent reservoirs in the CNS, and whether we can target the unique viral infection and latency signaling pathways to attack HIV reservoirs in CNS for a cure/remission of HIV-1 and HIV-associated neurocognitive disorders (HAND). We have developed multiple tools to attack HIV latency, including latency reversal agents for “Shock and Kill” strategy, such as histone deacetylase inhibitors and ingenol family compounds of protein kinase C agonists, and latency enforcing agents for deep silencing of latent HIV-1. Several clinical and pre-clinical studies are being tested to evaluate their potential to eradicate latent HIV reservoirs in vivo. We are actively recruiting postdocs, visiting scholars, and technicians. Rotation graduate students and undergraduate students are welcome to join my lab, located in the UNC HIV Cure Center, for these exciting HIV cure research projects. |
Drewry, David H WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
The Drewry lab is focused on designing, synthesizing, evaluating, and sharing small molecule chemical probes for protein kinases. These tools are used to build a deeper understanding of disease pathways and facilitate identification of important targets for drug discovery. Through wide ranging partnerships with academic and industrial groups, the Drewry lab is building a Kinase Chemogenomic Set (KCGS) that is available to the community for screening. |
Liu, Rihe WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
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. |

PHD PROGRAM RESEARCH INTEREST |
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. |
McGinty, Robert WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
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. |

PHD PROGRAM RESEARCH INTEREST |
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. |
