To develop targeted therapy against cancer stem cells

Cancer is a multifactorial disease that involves de-regulation of various signaling pathways. Our aim is to develop a multiple signal modulation therapy of cancer adopting different approaches, i.e., (i) to induce apoptosis even in drug-resistant cancers, (ii) to retard metastasis, and (ii) to inhibit angiogenesis, in cancer cells. According to the recent hypothesis, tumorigenesis, metastasis and drug-resistance are driven by a limited subpopulation of tumor-initiating cells, i.e., cancer stem cells (CSCs). CSCs retain stem like properties, e.g., ability to self renew, increased proliferative capacity, and ability to differentiate into different lineages. Recent aim of our study is to uproot cancer from its origin by understanding the basic properties of CSCs and targeting them directly. To that end, my laboratory intends to map the molecular mechanisms of CSC-induced drug-resistance, metastasis, and angiogenesis in tumor-bearer and to repurpose commonly used FDA-approved drugs, e.g., aspirin, metformin, etc., and alternative medicines like thuja (homeopathy) in targeting CSCs. Aim of this study is also to delineate the fundamental properties of cancer stem cells in relation to their role in modulating the immune system so that pro-CSC immunity, which might be responsible for the failure of immunotherapy, can be targeted with the final aim of developing an effective immunotherapy of cancer.
