Figure 4
Expression levels of phosphorylated FOXL2, PKA, and Smad3 proteins in cultured porcine granulosa cells in response to varying concentrations (0, 50, and 200  μg/mL) of anti-inhibin α-subunit antibody treatment, normalized to β-actin expression. Each value (plus SEM) represents the average data of 4 independent culture experiments, each with 2 duplicate wells. Means marked with different letters are significantly different (a-b: P < 0.01).
