In the case of breast tumor xenograft mice, TQ combined with doxorubicin showed high inhibition of tumor growth through enhancing p-p38 protein expression in tumor tissues, downregulating XIAP, survivin, Bcl-xL and Bcl-2; at the same time it raised catalase, SOD and glutathione levels in liver tissues [35]. This evidence concerns the gene BCL2 and neoplasm.
