Abstract
- Maternal exposure to dibutyl phthalate (DBP) may result in obesity in female offspring. However, the underlying mechanisms remain elusive. Sprague-Dawley rats were intraperitoneally injected with different doses of DBP and corn oil from gestational day 7 until the end of lactation. The weights, visceral fat percentage, serum lipid, insulin and glucose, protein levels of PI3K signal pathway in muscle were detected in F1 female offspring. Although the birth weight of F1 female offspring was not different among groups, the weights were heavier in DBP groups from postnatal day 7 to adult (P < 0.001). The visceral adipose percentage in adult female offspring was increased by perinatal exposure to DBP (P < 0.001). Decreased serum level of triglyceride (P = 0.001) in F1 female offspring was found in DBP group as compared to control, especially in medium and high DBP. However, none difference was found for fasting glucose, prolactin, HOMA-IR, fasting insulin, total cholesterol, adiponectin. Different protein levels of GPR30 were observed in muscle of female offspring among four groups (P = 0.016). The protein level of AKT seemed higher in DBP group but without statistical significance (P = 0.05). None difference was observed for the protein levels of PI3K, p-AKT, pAKT/AKT, PTEN, GLUT4, InsR, IRS. Maternal perinatal exposure to DBP might induce obesity and accumulation of visceral adipose tissue for the adult female offspring. Serum glucolipid and local signal transduction of PTEN/PI3K/AKT pathway in muscle were not adversely affected by perinatal exposure to DBP for adult female offspring. [ABSTRACT FROM AUTHOR]
