The effects of NDV infection on the mRNA expression of steroidogenesis related key protein StAR and enzymes P450scc, 3βHSD, and 17βHSD4 in rooster testis. Data are presented as mean ± standard deviation. The data were analysed by two-way ANOVA test, with challenge and time points as the main effects. StAR: Steroidogenic acute regulatory protein; P450scc: Cholesterol side-chain cleavage enzyme; 3βHSD: 3β-hydroxysteroid dehydrogenase.
