Targeting TGF-β: a promising strategy for cancer therapy

Transforming growth factor β (TGF-β) has important role in regulating the cellular processes including cell growth, differentiation, and migration. TGF-β exerts its effect by binding with transcellular membranes and kinases. Our findings demonstrate that TGF- β possess dual role as tumor suppressor and tumor promoter in different stages of cancer. TGF-β emerged as a promising anticancer agent that exhibits the apoptosis by acting on the suppressor of mothers against decapentaplegic (SMAD) and non-SMAD pathways. In this review we are focusing on the different types of TGF- β inhibitors active against skin cancer, breast cancer, colorectal cancer, lung cancer and ovarian cancer. TGF-β inhibitors includes ligand traps, monoclonal antibodies and receptor kinase inhibitors. In recent studies, TGF- β inhibitors have also been used in combination therapies in the treatment of cancer. The TGF-β has important role in vaccine therapy, Chemo and Radio Resistance in Cancer. TGF-β inhibitors present the novel therapeutic approach for the cancer therapy, highlighting the mechanism of action involved, clinical trials, challenges and exploring therapeutic opportunities. This will help to develop the novel TGF-β inhibitors as anticancer agents as well as help to resolve the problem of drug resistance by developing new drugs as anticancer agents.

Curcumin as a potential inhibitor of TGFβ3 computational insights for breast cancer therapy

Previous research indicates that Transforming growth factor beta-3 (TGFβ3) expression levels correlate with breast cancer metastasis, and elevated TGFβ3 levels have been linked with poor overall survival in breast cancer patients. The study used computational methods to examine curcumin's effects on TGFβ3, a chemical with antiviral and anticancer characteristics. The curcumin has low Molecular Weight 368.130 (MW) and follows Lipinski Rule, Pfizer Rule, GSK Rule, Golden Triangle, BMS Rule, zero PAINS alert and Acute Toxicity Rule with zero alert. Any drug-like contender must follow these qualities. Through molecular docking analyses, curcumin displayed favourable binding affinities at the TGFβ3 binding pocket, forming key interactions such as hydrogen bonds with residues like ASP323, ARG325, VAL333, HIS334, PRO336, LYS337, GLY393, and ARG394. 500 ns molecular dynamic simulations examined docking interactions. Molecular dynamics (MD) simulations trajectories analysis, by calculating lower structural deviation, minimal residual fluctuations, structural compactness assessment by calculating radius of gyration, surface area calculation which interact with solvent, role of hydrogen bonding, and secondary structural analyses. Furthermore, principal component, Gibbs free energy landscape and MMPBSA analysis, signifying system stability. These data suggest curcumin may inhibit TGFβ3, providing a framework for developing new compounds targeting this protein.
