  • Daria Gaykalova Lab

    The Daria Gakalova Lab defines the functional role of epigenetics in transcriptional regulation of head and neck squamous cell carcinoma (HNSCC) progression. To evaluate the whole-genome distribution of various histone marks, her team is using chromatin immunoprecipitation followed by massively parallel DNA sequencing (ChIP-Seq) for primary tissues, a method recently developed by her lab. The research group of Daria Gaykalova was the first to demonstrate the cancer-specific distribution of H3K4me3 and H3K27ac marks and their role in cancer-related gene expression in HNSCC. The research showed that an aberrant chromatin alteration is a central event in carcinogenesis and that the therapeutic control of chromatin structure can prevent the primary of secondary cancerization. Further preliminary data suggest that the differential enrichment of these disease-specific histone marks and DNA methylation correlate with alternative splicing events (ASE) formation. For this project, Dr. Gaykalova... and her team employed a novel bioinformatical tool for the detection of cancer-specific ASEs. Through thorough functional validation of the individual ASEs, the lab demonstrated that each of them has a unique mechanism of malignant transformation of the cells. Due to high disease specificity, ASEs represent the perfect biomarkers of the neoantigens and have direct application to clinical practice. view more

  • Gary S. Hayward Laboratory

    Research in the Gary S. Hayward Laboratory is related to human herpesvirus. Specifically, researchers are seeking to understand how the different classes of herpes viruses take control of transcription, DNA replication, cell cycle and other nuclear processes of their host cells and how they also block or evade apoptotic and immune responses in both the lytic and latent state.

    Research Areas: immunology, herpesvirus, pathogenesis, transcriptional regulation

  • Wolberger Lab

    The Wolberger Lab is interested in the structural and mechanistic basis for transcriptional regulation and ubiquitin signaling as it relates to the integrity and expression of the genome. We use x-ray crystallography, enzymology, cell-based assays and a variety of biophysical tools to gain insights into the mechanisms underlying these essential cellular processes.

    Research Areas: biophysics, ubiquitin signaling, genomics, transcriptional regulation
