Effect of ATRA on the HSD17B2-mRNA expression in the cultured choESC. Cells were obtained from three different individuals, and the cells from a given individual were cultured in triplicate. The cells were treated with the indicated concentrations of ATRA for four days. The values are shown as mean ± SEM of three experiments. *P < 0.05 vs. control, ATRA: 10⁻⁹ M, and 10⁻⁸ M
