Yue et al. indicated that metformin combined with aspirin synergistically inhibited tumor growth, migration, and colony formation in human pancreas cancer PANC-1 and BxPC-3 cells cultured in vitro and pancreas tumor xenografts in nude mice, by remarkably inhibiting the phosphorylation of STAT3 and mTOR, significantly downregulating the antiapoptotic proteins Bcl-2 and Mcl-1 and significantly upregulating the proapoptotic proteins Puma and Bim [48]. Here, BCL2 is linked to pancreatic neoplasm.
