Ms. Sucheta Sharma | Her research aimed at developing new therapeutic strategies for aggressive Triple-Negative Breast Cancer (TNBC). Her project, titled “Deciphering the Role of the CYP2J2/EETs Axis in the Lipid Epoxygenase Pathway as a Novel Therapeutic Approach Against TNBC”, investigates how epoxyeicosatrienoic acids (EETs)—metabolites of arachidonic acid produced by CYP2J2—contribute to cancer angiogenesis and metastasis. The study evaluates the efficacy of USFDA-approved CYP2J2 inhibitors in combination with cannabidiol (CBD) derivatives to target this pathway. | (DST-Inspire) |

Mr. Sahil Wassan |
Currently engaged in research exploring the molecular mechanisms and therapeutic potential of CB2 and TRPV1 agonists in leukemia. The study focuses on evaluating the impact of CB2 and TRPV1 receptor activation on gene expression in acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) cells, particularly in relation to apoptotic pathways, proliferation markers, and immune regulation. This work aims to uncover novel, targeted, and low-toxicity therapeutic strategies that could improve treatment outcomes and help overcome drug resistance in leukemia. |

Her interest includes the discovery and development of novel small-molecule inhibitors targeting key oncogenic signaling pathways. He is currently focused on a thieno[3,2-d]pyrimidinyl-based compound, specifically ((piperidin-4-yl)urea) derivatives, as potent, selective, and orally bioavailable inhibitors of 3-phosphoinositide-dependent kinase-1 (PDK1). This research aims to evaluate their therapeutic potential in triple-negative breast cancer (TNBC), demonstrating significant in vitro and in vivo antitumor efficacy, with the goal of advancing targeted therapies for aggressive and treatment-resistant cancer subtypes. |

Dr. Sameer K. Varma |
He is developing a clinical-grade dendritic cell-based immunotherapy for triple-negative breast cancer (TNBC)—a highly aggressive subtype that predominantly affects younger women and lacks effective targeted therapies. He is leading the innovation of a non-viral delivery system for precise antigen loading into dendritic cells. This strategy significantly enhances MHC-I and MHC-II expression, resulting in highly potent antigen-presenting cells capable of activating both cytotoxic and helper T cells. The outcome is a strong, specific immune response against TNBC. Together, we are building a safe, scalable, and translational immunotherapy platform, grounded in cutting-edge science and a steadfast commitment to patient-centered innovation. |
