Abstract

4-Amino-2-trifluoromethyl-phenyl retinate (ATPR) is a novel all-trans retinoic acid (ATRA) derivative which was reported to have a superior antitumor effect in breast cancer cells. However, little is known about its antitumor effects on human gastric cancer cells and the mechanisms have not been fully elucidated. The results of the present study suggest that in the human gastric carcinoma cell line BGC-823, ATPR plays a more effective role than ATRA at the same dose in inhibiting proliferation, migration and inducing differentiation after the same treatment time. Furthermore, we investigated the preliminary mechanism of ATPR's anti‑migration effect. Immunofluorescence assay demonstrated that claudin-18 positioned from cytoplasm to cell surface following ATPR stimuli. Real-time quantitative RT-PCR and western blot analyses showed that ATPR had significant effects on downregulation of the phosphorylation level of myosin light chain II (MLC II) by suppressing myosin light chain kinase (MLCK) and Rho-associated coiled-coil containing kinase (ROCK), as well as its regulation in the protein expression of RARα and RARβ. Moreover, ATPR increased the activity of myosin phosphatase by inhibiting ROCK. Consequently, ATPR showed more promising antitumor effects than ATRA in BGC-823 in vitro, and it may conduct its anti-migration effects by decreasing the phosphorylation level of MLC II, as well as by regulating MLCK and ROCK as downstream target genes.
