Maternal obesity induced by high fat diet (HFD) during pregnancy and lactation.can negatively interfere in the development of offspring. In adulthood, obesity and lipid overload represent factors that compromise autophagy, a process of lysosomal degradation that is essential for the maintenance of cellular homeostasis. Based in this context, the aim of this study was to evaluate the protein content of LC3-II, a principal marker of cellular autophagy, in the hypothalamus and liver of offspring at birth, after weaning and in adulthood. At birth, the offspring showed a decrease of LC3-II protein content only in the liver of offspring from obese dams (HFD-O) when compared to offspring control (SC-O). At weaning LC3-II decreased in both hypothalamic and hepatic tissue. However, during adulthood there were no differences between the groups. Overall, we believe that this study demonstrates that offspring's LC3-II, as well as in adulthood, is also highly associated with exposure to lipids and obesity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
