Fig. 6From: Melatonin receptor depletion suppressed hCG-induced testosterone expression in mouse Leydig cellsKnockdown of MTNR1A and MTNR1B promotes apoptosis genes. a-c. Relative mRNA expression of cell apoptosis marker genes, Bcl-2, p53 and caspase-3, after treatment with the siRNAs against MTNR1A and MTNR1B for 48 h in mLTC-1. The mRNA expression level was normalized to that of Gapdh. Data are presented as the mean ± SEM of three triplicates. *P < 0.05, **P < 0.01 (Student’s t-test)Back to article page
