چکیده مقاله:

Leptin, the ۱۶-kDa product of the obese (ob) gene, primarily secreted from adipose tissue, has been implicated to play an important role in the regulation of food intake and energy expenditure. This study investigated protective effect of leptin on trichostatin A-induced apoptotic on in vitro maturation ratio of buffalo oocytes. Ovaries were collected from abattoir and were transported immediately to the laboratory by a thermos flask containing sterile normal saline with antibiotics. Oocytes were aspirated from ۲ to ۸ mm visible follicles. Oocytes were placed in a culture plate and then incubated at ۳۸.۵ ˚C with ۵% CO۲ in air for ۲۴ hr. The maturation of oocytes was evaluated under a stereomicroscope. The FITC-Annexin V and propidium iodide staining method was used to detect oocyte apoptosis. In leptin treated groups with ۰, ۱۰, ۵۰ and ۱۰۰ ng mL-۱ and groups that apoptosis was induced, the percentage of oocytes maturation was ۷۷.۰۳, ۸۶.۱۲, ۸۵.۰۸, and ۷۹.۸۹% and ۵۹.۹۶, ۵۶.۹۳ and ۵۱.۹۸, respectively, while the percentage of apoptosis was ۸.۸۳, ۷.۹۰, ۸.۵۸, and ۹.۳۹%, and ۱۰.۳۷, ۱۱.۵۷ and ۱۲.۰۳, respectively. Our findings showed that addition of ۱۰ and ۵۰ ng mL-۱ leptin to IVM medium of buffalo oocytes could increase oocyte nuclear maturation, and could decrease oocyte apoptosis when trichostatin A added for inducing apoptosis.
