Luteolin enhances paclitaxel-induced apoptosis in human breast cancer MDA-MB-231 cells by blocking STAT3.

The potential use of low-dose chemotherapy has been appealing because lower dosages are more attainable during cancer therapy and cause less toxicity in patients. Combination therapy of paclitaxel, a promising frontline chemotherapy agent, with natural anti-tumor agents that are considerably less toxic and possess the capability of activating additional apoptotic signals may provide a rational molecular basis for novel chemotherapeutic strategies. Luteolin, a natural flavone, possesses multiple biological activities, including anti-tumor potential.
