Research:

Complex diseases are caused by interaction of multiple genes and environmental factors. We know that complex diseases do not follow the standard Mendelian patterns of inheritance. Although we inherit genes associated with these diseases, genetic factors are responsible only for partial risk associated with complex disease phenotypes. Epigenetic factors are also known to play important role along with environmental and life-style factors and it is very important to understand their relative contribution in modulating the overall pathophysiology of the disease.

Broadly, the interest of our laboratory is to identify genes, loci and epigenetic changes that confer susceptibility to some complex disorders, to elucidate how they influence the pathogenesis, and to translate this information into improved patient care both in terms of better diagnosis of the disease and better treatment options.

Currently, we are focusing on several gastrointestinal diseases.

Pancreatic Diseases:

Chronic Pancreatitis (CP) is a disease of the pancreas where progressive inflammation of the organ ultimately leads to the destruction of both exocrine and endocrine part of pancreas resulting in high morbidity and mortality. The disease also increases the susceptibility of the patients to develop pancreatic ductal adenocarcinoma (PDAC) representing a classic model of progression of chronic inflammation to malignancy. Notably, PDAC is one of the most aggressive cancers lacking early diagnostic biomarkers. We aim to:

  • (a)  Elucidate genetic changes which could explain the development of CP.
  • (b)  Pursue comprehensive analysis and integration of transcriptomic and methylome data and functional characterization of key leads to have a mechanistic idea of development of PDAC from chronic inflammatory disease of the pancreas.
  • (c)  Focus on the role of noncoding RNAs in this process (miRNA, long noncoding RNA, circular RNA) with special emphasis to explore their role as non-invasive diagnostic or prognostic biomarker.
  • (d)  Exploring the involvement of m6A RNA methylation in pancreatic cancer.

The following figure, adopted from Chhatriya et al., PINSA., Vol 84 No 2 (2018):501-511; summarizes the core area of our research interest

     

Colorectal cancer:

Another area of interest is early onset aggressive subtype of colorectal cancer in Indian population as described by Raman R et al. (Mol Carcinog. 2014 Feb; 53(0 1): E181–E186). We plan to investigate the genetic and epigenetic underpinnings of the disease and aim to relate them to the actual mechanism. Role of microsatellite instability will also be explored.
