| Abstract | ||
| The present study has been designed to quantitate the mRNA expression level of testicular Inha, Inhba, and Inhbb genes at pre- and post-pubertal stages of male Wister rats. Fifty male Wister rats (25 immature and 25 mature) were used in the present study. At pre-pubertal stage, 5 male rats of 25, 30, 35, 40, and 45 days old, and at post-pubertal stage, 5 male rats of 55, 60, 65, 70, and 75 days old were anasthetized and testis were obtained for molecular study to investigate the expression levels of Inha, Inhba, and Inhbb genes using qRT- PCR. The expression level of Inha gene in testis decreased as the age progress until 40 day period, and then slightly increased at 45 day period. At 55 day period, the expression significantly increased. At 60 and 65 periods, the levels recorded no increase, but 70 and 75 day periods recorded significant increase. The expression level of Inhba gene increased significantly as the age progress at the pre-pubertal stage, where the highest level was recorded at 45 day. At 55, 60, and 65 day periods, the highest expression level has been recorded, thenafter, the levels decreased at 70 and 75 day periods. The expression level of Inhbb gene increased significantly at 30, 35, 40, and 45 day periods of the pre-pubertal stage. At 55 and 60 day periods, no significant difference was recorded compared with 45 day period. At 65 day period, the highest level was recorded, thenafter, the levels decreased at 70 and 75 day periods. It can be concluded that fold changes of Inha, Inhba, and Inhbb genes in testis, correlated with the alterations of inhibins and activins concentrations at different periods of pre- and post-pubertal stages of male Wister rats life. | ||
