Unexpected Long-Term Protection of Adult Offspring Born to High-FatFed Dams against Obesity Induced by a Sucrose-Rich Diet

摘要

BackgroundMetabolic and endocrine environment during early life is crucial for metabolic imprinting. When dams were fed a high fat diet (HF diet), rat offspring developed hypothalamic leptin resistance with lean phenotype when weaned on a normal diet. Interestingly, when grown on the HF diet, they appeared to be protected against the effects of HF diet as compared to offspring of normally fed dams. The mechanisms involved in the protective effect of maternal HF diet are unclear.
