In contrast, "alpha1,3FucT-VII" cells facilitated the apoptosis induced by all-trans retinoic acid (ATRA), which was verified by the greater sub-G1 (apoptotic cells) peak in flow cytometry analysis, more expressions of active caspase-3 and pro-apoptotic protein Bax, as well as less expressions of anti-apoptotic proteins, Bcl-2 and Bcl-X(L).
