Abstract:
The present work was undertaken to study the expression pattern of CYP19 in ovarian antral follicles of tropical goats. CYP19 is a gene which codes for the enzyme aromatase. Oestradiol is synthesized from androgen in granulosa cells of the ovarian follicles by the action of aromatase. Our results showed that in caprines at proestral stage there was no significant difference between the expression of CYP19 in different categories of antral follicles (small follicles: - 1-3mm and large follicles: - < 3 mm diameter). An increase in the expression of CYP19 gene was observed in large follicles when compared to small follicles, the reason for the increased expression might be the formation of more granulosa cells towards later stage of follicular development.
