Research Interest:

Microbiome and Human Cancers

Summary of Research:

There are increasing research reports which establish the link between human microbiota and carcinogenesis. Pathogenic bacteria and altered microbiota interact with mucosal surface and as a result, epithelial damage can be seen especially in chronic infection conditions. It can be reckoned that gut microbiota-derived metabolites play key role in epithelial damage and carcinogenesis. More and more intriguing data are hinting at a much broader link between microbiota, bacterial infections, inflammation and carcinogenesis. The mechanism of this relationship between bacteria and human cancer is not well studied and understood, hence our laboratory aim to delineate this complex interaction among microbiota, bacterial infections, inflammation and carcinogenesis. We also plan to explore the role of bacteria, microbiota and their metabolites in enhancing cancer immunotherapy.

Current Projects 

Towards understanding the link between intestinal microbiota and colorectal cancer 

The gut microbiota is considered as a forgotten organ in human health and disease. It maintains gut homeostasis by various complex mechanisms. The dysbiosis or disruption of gut flora has been confirmed to be related to gastrointestinal diseases such as CRC and other diseases in different organs. Colorectal cancer is a multi-factorial and multi-stage involved disorder. The role for microorganisms that initiate and facilitate the process of colorectal cancer has become clear. Our group is studying the link of gut microbes in colorectal cancer causation. Clearly, more information is needed about mechanisms through which the microbial community promotes carcinogenesis. Understanding the events leading to development of intestinal carcinogenesis through gut microbes will provide novel insight into this pathology, and potentially lead to new therapeutic modalities targeting the microbiota.

Sensor/biosensor for detection of gut bacteria and their metabolites

The microbiota-derived metabolites such as Trimethylamine N-oxide (TMAO) have been implicated in human health and disease, and their early detection in the body fluids is thought to be significant in understanding pathogenesis and treatment of colorectal cancer and other diseases like Alzheimer’s disease, cardiovascular, cerebrovascular etc.   Recent studies have identified a number of metabolites and microbes that have important roles in human health and disease and can be considered as biomarkers for diagnosis of different diseases.
