Our research is focused on RNA-binding proteins and their physiopathological roles. An understudied aspect of human disease is gene regulation by modulation of mRNA function. In our research lab we investigate functional connections between the RNA-binding protein Zinc Finger Protein 36 Like-2 (ZFP36L2 or L2) and human diseases. L2 is a member of the Tris-Tetra-Proline or Zinc Finger Protein 36 (TTP/ZFP36) family of RNA-binding proteins that bind Adenine-uridine-Rich Elements (AREs) in the 3’ untranslated regions of target mRNAs. Upon binding, L2 accelerates mRNA target degradation and/or inhibits mRNA translation, ultimately decreasing the protein encoded by the L2-target mRNA.

We have three particular goals:

  • Determine new specific L2-mRNA targets involved in human diseases.
  • Determine the mechanism(s) by which L2 modulates these novel RNA targets.
  • Determine the physiological consequences of L2 ablation in specific cells types using mouse models and CRISPR/Cas9-mediated knockout system.

My research has focused on developing new radio-chemistry, imaging probes, and therapeutic approaches including nanomedicine for various diseases. Most importantly, we have the culture of forming an active collaboration with people in different field. With a cGMP lab located within our facility, we are also experienced on developing lead agents and translate it to clinic.

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.

The Button lab in the Department of Biochemistry and Biophysics is part of the Marsico Lung Institute. Our lab is actively involved in projects that are designed to define the pathogenesis of muco-obstructive pulmonary disorders and to identify therapies that could be used to improve the quality of life in persons afflicted by these diseases. In particular, our research works to understand the biochemical and biophysical properties of mucin biopolymers, which give airway mucus its characteristic gel-like properties, and how they are altered in diseases such as Asthma, COPD, and cystic fibrosis.

Our lab is interested in the mechanisms of membrane trafficking in eukaryotic cells. Using a combination of biochemistry, in vitro reconstitution, and structural biology, we seek to understand how protein complexes assemble to bend and perturb membranes during vesicle budding (endocytosis) and vesicle fusion (exocytosis). Our group also specializes in cryo-electron microscopy (cryo-EM) and we use semi-native substrates (nanodiscs, liposomes) to visualize complexes engaged with the membrane.

Our lab studies pathways that regulate genome instability in cancer, which is a cancer hallmark associated with clinically aggressive disease. We utilize CRISPR-enhanced murine models of breast cancer to interrogate the impact of DNA damage response gene mutations on cancer pathogenesis and therapeutic susceptibility. We have identified an alternative DNA double strand break repair pathway as a driver of genome instability in a subset of breast cancers, and are investigating its potential as a therapeutic target.  We also study how deficiencies in DNA repair can impact responsiveness to immunotherapy. Finally, we have developed sensitive assays for detecting circulating tumor DNA (i.e., “liquid biopsy”) in cancer patients, with an interest in validating predictive biomarkers for personalized cancer therapy.  These translational studies are currently being performed in patients with breast cancer and cancers that arise in the head/neck.

With an emphasis on chromatin biology and cancer epigenetics, our group focuses on mechanistic understandings of how chemical modifications of chromatin define distinct patterns of human genome, control gene expression, and regulate cell proliferation versus differentiation during development, and how their deregulations lead to oncogenesis. Multiple on-going projects employ modern biological technologies to: 1) biochemically isolate and characterize novel factors that bind to histone methylation on chromatin, 2) examine the role of epigenetic factors (chromatin-modifying enzymes and chromatin-associated factors) during development and tumorigenesis using mouse knockout models, 3) analyze epigenomic and transcriptome alternation in cancer versus normal cells utilizing next-generation sequencing technologies, 4) identify novel oncogenic or tumor suppressor genes associated with leukemia and lymphoma using shRNA library-based screening. We are also working together with UNC Center of Drug Discovery to develop small-molecule inhibitors for chromatin-associated factors as novel targeted cancer therapies.

If you are interested in developing new biochemical/molecular techniques/tools to advance our understanding of biology, and if you are interested in signal transduction pathway analyses and identification of cancer biomarkers, our research group may help you to achieve your goals, as we have the same dreams. We are especially interested in deciphering the molecular mechanisms underlying aberrant signaling events that contribute to tumorigenesis, mediated through protein modifications and protein-protein interactions. Understanding these events may lead to identification of novel drug targets and provide new treatment strategies to combat human cancer.

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.
