Maintaining the integrity of the genome is essential for the survival of a cell and genomic instability is associated with many human diseases including cancers. A cell ensures the integrity of its genome with an intricate interplay of epigenetic mechanisms to safeguard nuclear processes, including chromosome segregation, repair of DNA damage lesions and gene expression. Our lab aims to investigate the epigenetic mechanisms at the molecular level by:
* Identifying and characterizing factors that epigenetically control essential chromatin functions that have direct implication to genomic stability.
* Elucidating how different epigenetic mechanisms interplay to control faithful inheritance of chromatin information through the cell cycle.
* Investigating the genetic and epigenetic regulation of functional sub-nuclear compartments.
Our lab employs the powerful genetics, cytology and biochemistry of the model organism fission yeast to address these important issues. Results obtained will be extended to elucidate epigenetic mechanisms operating in the mammalian cells, to facilitate the development of therapy for human diseases and cancers.
