Effect of MIR143 on steroidogenesis and cell apoptosis in pGCs. (A) Hormone measurement in the pGC culture medium. MNC was the MIR143 mimic negative control, and siNC was the siMIR143 negative control. (B) Effect of MIR143 in the expression of key genes related to hormone biosynthesis. (C) Protein analysis of HSD17β4, ER1, ER2, CYP11A1, PTGS2, and CYP19A1 with or without hCG stimulation. The protein relative gray value = protein gray value/β-actin gray value. (D) Cell apoptosis analysis and mRNA levels of cell proliferation markers PCNA, and apoptosis biomarkers BCL2, BAX, and Caspase 3. *P < 0.05, **P < 0.01.
