Profile

The major focus of our laboratory is to explore how mammalian long noncoding RNAs [lncRNAs] regulate gene expression and to develop a mechanistic understanding of how these lncRNAs regulate events associated with oncogenesis. Our research group is involved in comprehensive characterization of novel lncRNA-protein network orchestrating the mammalian cell cycle program. Further, our interest also extends towards investigating the role of lncRNAs in DNA replication stress response, DNA damage and repair, genome stability; and in oncogenic or tumor suppressive functions of lncRNAs in cancer. Additionally, our laboratory also focusses on how various RNA modifications modulate the activity of ncRNAs.

Current Focus Areas

  • lncRNA-protein interactions during DNA replication, DDR and maintenance of genomic integrity

  • Oncogenic and/or tumor suppressive functions of lncRNAs in cancer

  • lncRNA modifications and their functional implications in various biological processes

  • lncRNA-mediated regulation of LLPS of nuclear proteins
