Effects of fucoxanthin on proliferation and apoptosis in human gastric adenocarcinoma MGC-803 cells via JAK/STAT signal pathway.

In this study, we investigated the anti-tumor effects and possible mechanisms of fucoxanthin, which has been reported to inhibit tumor proliferation and induce apoptosis in vitro or in vivo. Human gastric adenocarcinoma MGC-803 cells were treated with fucoxanthin (25μM, 50μM or 75μM). Data of flow cytometry revealed that fucoxanthin (50μM or 75μM) increased the ratio of cell in G2/M phase and apoptotic MGC-803 cells varying on a dose-dependent manner.
