Lung cancer is the leading cause of cancer-related deaths among both men and women in the U.S and worldwide. Today, paclitaxel (PAC) or taxol alongside platinum-based drugs is the most widely used agent as the first-line regimen for advanced NSCLC. However, due to toxicity, drug resistance, solubility and efficacy issues, efficacy has plateaued. In the present study, the potential of a novel plant-derived steroidal-lactone, withaferin A (WFA), for clinical use alongside PAC to improve efficacy against NSCLC was explored. The anticancer effects of PAC and WFA alone, and in combination against the in vitro cell proliferation, cell adhesion, migration and invasion of two human NSCLC cell lines, H1299 and A549 were determined. Our data shows that PAC and WFA, combined at 1:25 and 1:50 ratios, respectively, synergistically inhibited the proliferation of H1299 and A549 cells. Furthermore, the combination also significantly inhibited the TGFβ1-induced EMT, cell adhesion, migration, and invasion (pp
