Our lab focusses on understanding the tumor microenvironment (TME) of pancreatic and prostate cancers, with emphasis on immune regulation, stromal interactions, and infection-driven inflammation. We develop and use clinically relevant animal models and patient-derived samples to explore mechanisms of cancer progression and identify novel therapeutic strategies, including drug repurposing and immunomodulation. In parallel, we investigate the role of probiotics and microbiota in health and disease, advancing indigenous and marine probiotic strains as potential bio-therapeutics. Our expertise in animal models also enabled critical contributions to COVID-19 research and therapeutic development. Understanding and targeting pancreatic cancer tumor microenvironment One of the major focus of lab is to elucidate the cellular and molecular intricacies of Pancreatic Ductal Adenocarcinoma (PDAC) tumor microenvironment (TME) and evaluate potential TME-targeting therapies by using clinically relevant animal models and human patient derived cells and/or tissue samples. Immune competent animal models are potential tools to carry out TME related studies. In this regard our lab has characterised and used a hamster pancreatic cancer cell line (HapT1) -derived syngeneic PC tumor model (Oncotarget, 2016). The findings of this study motivated us to investigate the role of macrophage migration inhibitory factor (MIF) in PDAC. The findings of our study showed the pro-tumorigenic role of MIF expressed by both cancer cells and cancer associated fibroblasts (CAFs) (Scientific reports 2019; FASEB J., 2022). Recently, our lab has also established well characterised multiple syngeneic mouse pancreatic cancer cells lines derived from genetically modified mouse models. These cell lines derived animal models are helping us to address multiple questions associated with TME and its-targeted therapy. Our lab has a significant interest in identifying potential immunomodulators and in this regard we are exploring potential novel approaches by using existing drugs and/or novel drug candidates that could be useful to be used as potential therapeutic approaches. One of our studies has shown that gemcitabine induces polarization of mouse peritoneal macrophages towards an M1-like phenotype with antitumor effects via reactive oxygen species production (Clin Exp Metastasis, 2022). Further we reported that statins counteract gemcitabine-induced PD-L1 expression in pancreatic cancer-associated fibroblasts and cancer cells, leading to improved cancer therapeutic outcomes (Cancer Immunol Immunother, 2023). Our efforts on drug repurposing revealed that Fluvastatin can be used as radio sensitizer to suppress tumor-associated fibrosis (Lab Invest, 2021). One of our lab interests was to investigate the roles of cancer testis antigen molecules MAGEA3 and ATAD2 in PDAC. The findings of our study showed that MAGEA3 overexpression in pancreatic cancer cells confers survival advantage to these cells (J Exp Clin Cancer Res, 2019). Through collaborative studies we also found that MicroRNA-217 modulates pancreatic cancer progression via targeting ATAD2 (Life Sciences, 2022). These findings have provided rationale in designing potential novel therapeutics against PDAC. Currently, we are conducting two major studies with an objective to elucidate the heterogeneity of PDAC-associated CAFs and understand the role of different CAF subpopulations on immunomodulation. Investigating bacteria and its derived products on cancer pathogenesis and response to therapy Our lab has interest in understanding and targeting inflammation and/or infection-mediated events in prostate and pancreatic cancers. Like many other cancers, prostate cancer patients are susceptible to various infections. Our work demonstrated that TLR4 activation by lipopolysaccharide confers a survival advantage to growth factor-deprived prostate cancer cells, emphasizing the critical role of inflammation and innate immune signalling in cancer cell survival (Prostate, 2015). Another study revealed that lipopolysaccharide (LPS) enhances prostate cancer metastasis potentially through NF-κB activation, further highlighting the link between infection-driven inflammation and cancer progression (Prostate, 2018). Further, our study found Escherichia coli to be commonly present in benign prostate hyperplasia-associated microbiota, induces inflammation and DNA damage in prostate epithelial cells, linking infection with cancer development (Prostate, 2020). Currently, we are investigating the role of bacteria and its derived products on cancer TME and specifically on immune cells and its consequence on response to various therapeutics. Isolation, characterisation and use of probiotics for animal/human health and diseases Apart from cancer biology, our lab has emerged as a key contributor in investigating the role of indigenous probiotics in human health, disease prevention, and therapy. We initially participated in the ILS flagship project on- Tribal Health and Nutrition, funded by DBT, where our group isolated potential probiotic strains from tribal stool samples and traditional fermented beverages. This work led to the comprehensive characterization of promising indigenous probiotic strains such as Ligilactobacillus salivarius F14, Lactiplantibacillus plantarum ILSF15 and Levilactobacillus brevis ILSH3, highlighting their potential as novel bio therapeutics (World J Microbiol Biotechnol. 2023; Gene, 2024; Probiotics Antimicrob Proteins, 2024). Investigation of these strains provided critical insights into the genomic basis of probiotic function, safety and their adaptability to human gut environments while also demonstrating their antimicrobial, anti-cholesterol, and immunomodulatory properties. Our ongoing research is evaluating the preventive and/or therapeutic potential of these strains in models of non-alcoholic fatty liver disease and pancreatic cancer. Our lab is also an active participant in the multi-institutional Himalayan Bio-mission Project, funded by DBT. In this project, our group is conducting toxicological assessment of functional food formulations developed using characterized indigenous strains to ensure their safety and regulatory readiness for nutraceutical applications. Recently, our lab is actively involved in a new institutional initiative for Marine Bioprospecting under the Deep Ocean Mission (supported by MoES), where we aim to isolate novel probiotic candidates from marine ecosystems for use in functional foods, bio therapeutics, aquaculture, and environmental bioremediation. COVID-19 research and animal models With our prior expertise in developing clinically relevant animal models, our group played a pivotal role during the COVID-19 pandemic. Supported by BIRAC funding, we established the BRIC-ILS ABSL-3 animal challenge platform for SARS-CoV-2 research, making our institute one of the few national facilities capable of developing and utilizing such models at a critical time. This platform not only enabled essential COVID-19 studies but also served multiple government and private organizations in a fee-for-service mode. Our research contributed to understanding SARS-CoV-2 biology, transmission, and pathogenesis (FASEB J., 2021; Eur J Pharmacol., 2023; Indian Patent: 202231071195). Building on this foundation, we are now engaged in the identification and validation of potential drug candidates against COVID-19-associated lung fibrosis, leveraging both in vitro and in vivo models. |
