    Abstract:
    Our previous studies have demonstrated that prenatal caffeine exposure (PCE) induced an intrauterine programming of hypothalamic-pituitary-adrenal axis (HPAA)-associated neuroendocrine metabolism in 3-month-old offspring rats. In this study, we aimed to confirm this programming disorder and high susceptibility to metabolic syndrome (MS) in 10-month-old female PCE offspring with postnatal catch-up growth. We found that PCE female offspring rats showed decreased bodyweight but a higher rate of weight gain after birth. Moreover, in the offspring, basal hyperinsulinemia and insulin resistance were observed before unpredictable chronic stress (UCS), but serum total cholesterol (TCH) levels and triglyceride/high-density lipoprotein-cholesterol (TG/HDL-C), TCH/HDL-C and low-density lipoprotein-cholesterol/HDL-C (LDL-C/HDL-C) ratio changes were increased after UCS, accompanied by morphological damage of the related tissues. These results suggested that PCE adult female offspring rats were highly susceptible to MS, which is related to HPAA-associated neuroendocrine-metabolic programming disorder.
