      Research Interests

      Normal cells possess intrinsic mechanisms to avoid genetic mutations that contribute to the formation of cancer. One of these mechanisms is cellular senescence, defined as a permanent cell cycle arrest where the cell remains metabolically active but no longer capable to respond to proliferation stimuli. Methylation of histones plays an important role during senescence by contributing to the stable repression of genes involved in cell cycle progression. We now propose to investigate the role of chromatin structure and histone lysine methylation during senescence and cancer by studying the JUMONJI family of lysine demethylases.

      The focus of my research program is to examine the regulation of histone demethylases and the biological role of histone demethylation in different cellular processes including cell cycle, gene regulation, DNA damage response and tumorigenesis. The long-term objective will be to provide a better understanding of the role of protein demethylation in cancer leading to the development of potential therapeutics in the treatment of cancer. To this end, the laboratory will integrate several different approaches and systems to elucidate the crucial roles of histone demethylases in biological pathways. Using genomic (ChIP-chip, ChIP-seq, RNA-seq and microarrays), proteomic (MS-MS), cytological (fluorescence microscopy, immunohistochemistry), and genetic (cell lines and mouse) approaches, we will further investigate the role of histone demethylases in the DNA damage response and their impact on the recruitment of different DNA repair factors. Furthermore, the impact of the deregulated expression of demethylases in heterochromatin formation and oncogene-induced senescence (a tumor suppressive cell response) will be studied. I am also interested in the signaling pathways regulating activity of histone demethylases and their role in cellular transformation.

      This research will shed light not only on chromatin modifications underlying tumor suppression and cellular transformation, but also lead to the development of promising therapeutic strategies against cancer.
