  • 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
