Abstract
The present study identified the probable mechanism behind the anti-cancer activity of the hexane fraction of Pleurotus osteratus (HFPO) using network pharmacology and experimental validation. HFPO myco-metabolites targets and targets related to the cancer were mined from the online web server, and overlapping targets were screened. Out of the 74 overlapping targets, 33 targets were identified in the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway of cancer. Furthermore, the main active myco-metabolites and hub targets were identified by network analysis of the compound-targets network and protein-protein interaction (PPI), respectively. Molecular docking results showed good binding affinity of the hub targets with their respective myco-metabolites. HFPO induced in-vitro anti-cancer activity by affecting the PI3K-AKT-mTOR pathway, besides time-dependent cell cytotoxicity and apoptotic cell body formation. Additionally, tumor volume reduction was observed in HFPO-treated Ehrlich ascites carcinoma (EAC) bearing Swiss albino mice. Overall, HFPO induces anti-cancer potential by modulating the PI3K-AKT-mTOR signaling pathway.
