Résumé
Triple negative breast cancer (TNBC) is an aggressive breast cancer subtype that lacks hormonal receptors. This reduces the therapeutic options for TNBC patients creating more focus on chemotherapy. Drug resistance has posed as a major hurdle in treating TNBC patients. Deregulation of drug transporter proteins is one of major factors that cause resistance to chemotherapeutic drugs. In this study, ABCC6 a drug transporter protein that is found dysregulated in several resistant cancer cells has been docked with natural compounds or phytochemicals with known anti-cancer activities. Subtrifloralactone G, a withanolide extracted from Deprea subtriflora is found to show highest binding energy with ABCC6 protein. Molecular dynamics simulations further prove the stability of the ABCC6 protein- Subtrifloralactone G ligand complex. ADMET analysis shows that phytochemical Subtrifloralactone G can be used as an anti-cancer therapeutic drug in treating resistant cancer cells. The study mainly focuses on the role of phytochemicals in treating resistant TNBC cells.
Résumé
A total of 12 adult buffaloes were presented for the necropsy over the period of 6 months at the Department of Veterinary Pathology, CGKV, Anjora, Durg, Chhattisgarh. Prevalence of Gigantocotyle spp. parasite infection was found to be 16.67% (2/12). Significant number of parasites was found in the bile duct and ductules of the infected liver along with the necrotic debris caused by parasite. Other gross lesions observed were included hepatitis, haemorrhages and fibrosis of the liver. Black color hard nodules at the site of mucosal attachment of parasites were noticed. Microscopic changes observed were included bile duct hyperplasia, haemorrhages, moderate fibrosis and granulomatous nodule characterized by infiltration of inflammatory cells
