Previous research has shown that punicalagin, a main constituent of PoPEx, induced apoptosis in prostate and colon cancer cell lines, promyelocytic leukemia cells, and glioma cells by increasing the expression of the proapoptotic marker (Bax) X, downregulating the expression of antiapoptotic markers (Bcl-XL and Bcl-2) or suppressing nuclear factor (NF)-kB, depending on the investigated mechanisms [51]. Here, BCL2L1 is linked to malignant colon neoplasm.
