The highest level of SSAT1 mRNA expression was found in the pineal gland (P<0.05), and was 12-fold greater than in the heart. The level of SSAT1 mRNA expression was relatively lower in preovulatory follicles, while it was higher in postovulatory follicles (POFs), particularly in POF1. Furthermore, as postovulatory follicles degenerated, SSAT1 expression gradually decreased.
