Using Real time PRC method, we determined the Ct values of leptim gene in muscle, liver, kidney. The body weight of pigs ranged from 100 kg to 103 kg. The average body weight was 101.6 kg. The thickness of backfat ranged from 10 to 20 mm, average backfat thickness was 16 mm. The minimal Ct value of leptin gene in liver was 24.05 and the maximal value was 25.79. Average Ct value of leptin gene was 24.84. The minimal Ct value of leptin gene in muscle tissue was 25.83 and the maximal value was 27.05. Average Ct value of leptin gene was 26.41. The Ct value of leptin gene in liver ranged from 24.05 to 25.79. Average Ct value of leptin gene was 24.84. Leptin gene is expressed by porcine preadipocytes and leptin gene expression is highly dependent on dexamethasone induced preadipocyte differentiation. Hormonally driven preadipocyte recruitment and subsequent fat cell size may regulate leptin gene expression in the pig.
