CASP9 and cancer: Findings from the study exhibited anti-cancer and anti-metastatic properties of b-AuNPs (i.e., Curcumin alone and in combination with Paclitaxel) by controlling the expression of pro-oncogenes (MMPs, STAT, VEGF, Cyclin D) and enhancing the expression of the apoptotic gene (Caspase 9), anti-metastatic gene (E-cadherin), reduction in migration of cells in vitro, and reduction in the tumor size (in vivo).
