Again, the resveratrol derivative, 3,3′,4,4′-tetrahydroxy-trans-stilbene, and the analog cmpd1 stimulated CASP activity (3, 8, and 9) in ovarian cancer cells (24), glioblastoma cells (27) and ovarian cells (17); in the latter two cases, resveratrol also induced cleavage of poly(ADP ribose) (PARP-1) (17) and suppressed survivin, myeloid cell leukemia 1, B-cell lymphoma-extra-large (Bcl-xL) (27). This evidence concerns the gene SOX9 and glioblastoma.
