Research Area:

Poly(ADP-ribose) polymerase-1 (PARP-1), a family member of PARP, can modify its target proteins post-translationally and thereby can change the function of the target proteins. PARP-1 has long been known as a key player in DNA repair and hence a number of PARP-1 inhibitors have been used as chemo-sensitizer or radio-sensitizer. However, other than DNA repair activity, it can also perform other cellular/biological functions in the cell cycle, cell differentiation, inflammation, cell death like apoptosis, cancer progression, etc. Notably, a number of PARP inhibitors (iPARP) are in clinical trials and are showing promising results against various types of cancer. For example, BRCA mutant breast cancer and ovarian cancer are potentially treated by iPARP. Besides, other solid tumors like pancreatic, colorectal, and prostate show good results. Three FDA-approved iPARP such as Olaparib, Rucaparib, and Niraparib are available in the market. However, the mechanisms of action of iPARPs in various cancer types are still poorly understood. A Study of PARP-1 in DNA repair, apoptosis, and metastasis pathways would shed light on identifying novel multiple targets for cancer therapy. Our objectives are the functional characterization of PARP-1 in the repair of cluster DNA damage, apoptosis, and metastasis pathways in cultured human cancer cells after exposure to high and low LET radiation. We also want to screen synthetic compounds and natural products with anticancer activities. Telomerase is also a well-known target for cancer therapy because about 85% of cancer cells are telomerase-positive but normal cells except a few are telomerase-negative. Telomerase replenishes telomere shortening of highly dividing cancer cells and thereby helps uncontrolled growth of cancer cells. Other than telomerase, there is another recombination-based pathway (ALT) to maintain the telomere length. PARP-1 is involved in the telomere length maintenance pathway by telomerase and ALT pathway but the exact role is yet to be elucidated. We are interested to check the role of PARP-1 in telomere length homeostasis. We are also interested to screen the compounds having apoptotic properties and anti-metastasis and anti-telomerase activities. So, we have two major areas of interest:
 Functional characterization of PARP1 in DNA repair, Apoptosis & Metastasis pathway in human cancer cells treated with high LET Carbon ion, low LET gamma radiation, synthetic and natural compounds
 Regulation of Telomerase activity and Telomere length maintenance in mammalian cells & its implication in Human diseases
Research experience using high LET carbon ion:
We have been working on DNA Damage Response (DDR) pathway in different human cancer cell lines after exposure to high LET carbon ion [62 MeV (5.2MeV/u) with LET value 290 KeV/µM]. We have been using the ion beam facility from 15UD Pelletron of Inter-University Accelerator Center (IUAC), New Delhi since 2008. Several human cancer cells are exposed to various doses of carbon ion (12C) in the presence and absence of PARP-1 inhibitor, subsequently processed for measurement of DNA damage, repair, apoptosis, and metastasis. I also worked as visiting scientist in the Radiation Biology team LARIA group, CiMAP, GANIL, Caen, France in the collaborative research project (PROJECT FONDATION ARC 2015, France; Ref no: PJA 20151203177) in the year 2017. In that project, human chondrosarcoma cells were exposed to high LET carbon ion and low LET X-rays in the presence and absence of PARP-1 inhibitor to understand the mechanism of radio-sensitization. Also used the high LET carbon ion facility of Istituto Nazionale di Fisica Nucleare (INFN), Via S. Sofia, 62, 95125 Catania CT, Italy where we compared the cellular response of chondrosarcoma to both high and low LET radiations.
