Abstract
The aim of the present study was to evaluate the expression and effect of resistin on ovarian activities of Scotophilus heathi. Immunohistochemical study showed marked variation in resistin immunostaining during different reproductive phases. Most intense immunostaining of resistin was noticed in thecal-interstitial cells in ovary during the period of delayed ovulation, the period of increased androgen synthesis and suppressed ovulation. The changes in ovarian resistin level also correlated positively with circulating leptin level and body white adipose tissue accumulation. The in vitro study showed that resistin alone preferentially stimulated progesterone synthesis, but with luteinizing hormone (LH) stimulated androgen secretion. Resistin alone dose-dependently increased expression of LH-receptor, steroidogenic acute regulatory protein and insulin receptor proteins in the ovary, whereas together with LH showed dose-dependent stimulatory effect on expression of androgen receptor and insulin receptor proteins in the ovary. In conclusion, during the period of fat accumulation increased ovarian resistin level may be responsible for increased androgen synthesis through insulin receptor mediated pathways in the ovary of S. heathi.
