Our research is centered on comprehending the process by which normal cells transform into cancerous cells, with a specific focus on transcription, replication, and cell cycle processes. The cell cycle is a vital regulatory process that governs the life cycle of cells, and it is divided into two main phases: interphase and mitotic phase. The majority of a cell's life cycle is spent in interphase, which is comprised of three distinct phases: G1, S, and G2. The G1 and G2 phases are gap phases during which a cell prepares for DNA replication and division, respectively. The S phase, or synthesis phase, is when DNA containing genetic information is replicated. If errors occur during this phase that cannot be repaired, it can lead to mutations and, ultimately, cancer.
Our team is involved in understanding the basic mechanisms of S phase of cell cycle. In particular, we are more interested in some specific transcription factors and micro RNAs which may or may not affect the major regulators of the cell cycle. Also, we expertise in understanding the structural and functional aspects of major cell cycle regulators and their role in therapeutics. We employ a range of molecular biology techniques, cryo-EM, and various biochemical and biophysical methods to investigate the molecular mechanisms that underpin the regulation of the cell cycle.

We in collaboration with Dr. Lalit Agrawal (IMS, BHU) and his student Dr. Anju Srivastava discovered that in cervical cancer patients ccfDNA load increases as the cancer burden increases. Also, this ccfDNA load drastically decreases during chemo/radiation therapy. Hence, ccfDNA can be used to develop an efficient marker to detect chemoresistance in patients undergoing treatment and detection of cancer burden for CC patients.
We along with our collaborator Dr. Deepika Joshi and her student Aparna Khatri had discovered novel SNPs in SCN1A gene associated with Juvenile Myoclonic epilepsy which further need to be explored. We also have found a known mutation which is predominant in North Indian patient population and is related with higher GFAP serum level.
Our collaboration with Dr. Lalit from Department of Urology, IMS, BHU is about finding out microRNA signatures in the urinary bladder cancer patients. Our student Dr. Anil Kumar (M.Ch., Urology) detects the miRNA pattern in urine/ tissue sample to develop a potential theragnostic marker.
One of our objectives of collaboratory project with Prof. Sunil Choudhary (Radiologist, IMS, BHU) and Dr. Vimal Kishore (IoS, BHU) is to find out the source of ccfDNA in cervical cancer patients to develop a highly sensitive novel diagnostics marker. We are also trying to understand the radio-resistance in the CC patients.
In collaboration with Prof. Puneet (Surgery, IMS, BHU) our MD Student Dr. Saravana Bhaskar, is trying to identify the novel microRNA signatures in gallbladder patients which could be further used to develop potential therapeutics.
In collaboration with Prof. Dhiraj Kishore (Medicine, IMS, BHU) and his MD Student Dr. Aman Singh, we are trying to evaluate the level of circulating miR-126-3p in plasma of Type 2 DM patients to develop a minimally invasive diagnostic markers for Type 2 DM.
