Summary of Research:Microbiome and Human Cancer
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. Recent intriguing data is 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 are also exploring the role of bacteria, microbiota and their metabolites in enhancing cancer immunotherapy.
Current Projects
1. 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 of 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 the mechanisms through which the microbial community promotes carcinogenesis. Understanding the events leading to the development of intestinal carcinogenesis through gut microbes will provide novel insight into this pathology, and potentially lead to new therapeutic modalities targeting the microbiota.
2. Role of oral microbiota in colorectal cancer progression and Carcinogenesis
Recent reports indicate that the oral microbiome can colonize the gut, leading to dysregulation of the gut microbes. Furthermore, the oral-gut microbes create an intestinal inflammatory and immunosuppressive microenvironment conducive to tumorigenesis and progression of colorectal cancer. Our group is identifying oral bacteria and their metabolites which may be implicated for their genotoxic and carcinogenic role leading to colorectal cancer progression and carcinogenesis. This project is also aimed at studying oral to intestinal microbial transmission and the inflammatory and immunosuppressive microenvironment, induced by oral-gut axis microbes in the gut.
3. Sensor/biosensor for detection of gut bacteria and their metabolites
The microbiota-derived metabolites such as TMAO, TMA, Indoxyl sulfate, PCS, EPS, colibactin etc have been implicated in human health and disease, and their early detection in the body fluids is thought to be significant in understanding the pathogenesis and treatment of colorectal cancer and other diseases like Alzheimer’s disease, cardiovascular, cerebrovascular etc. These metabolites can also be considered as biomarkers for diagnosis of different diseases; hence our laboratory is involved in developing sensors/biosensors for quantifying the gut metabolites in body fluids like blood and urine.
