    Abstract:
    Chemoresistance has imposed a great challenge for cancer therapy. Fructus Ligustri Lucidi (FLL) is one of the commonest Chinese herbs that has been used for thousand years. This study shows that the aqueous extract of FLL (AFLL) enhanced the sensitivity of DLD-1 colon cancer cells to doxorubicin-induced apoptosis. Furthermore, Tbx3 expression was found to be suppressed by AFLL when the expression of tumor suppressor genes p14 and p53 were activated. Therefore, reduction of Tbx3 rescued the dysregulated P14(ARF)-P53 signaling, which in turn contributed to the sensitivity of DLD-1 cells to doxorubicin-induced apoptosis. As a conclusion, the findings suggest that FLL has a potential of being an appealing agent for auxiliary chemotherapy in treatment of human colorectal carcinoma.
