Study Title | Maternal obesity alters offspring liver and skeletal muscle metabolism in early post-puberty despite maintaining a normal post-weaning dietary lifestyle |
Study Summary | Maternal obesity (MO) during pregnancy is linked to increased and premature risk of age-related metabolic diseases in the offspring. However, the underlying molecular mechanisms still remain not fully understood. Using a well-established baboon model of MO, we analyzed tissue biopsies and plasma samples obtained from post-pubertal offspring (3-6.5y at sample collection) of MO mothers (n=19) and from control animals born to mothers fed a standard diet (CON, n=13). All offspring ate normal chow diet after weaning. With an untargeted gas chromatography-mass spectrometry metabolomics profiling, we quantified a total of 351 liver, 316 skeletal muscle and 423 plasma metabolites. We found 58 metabolites significantly altered in liver and 46 in skeletal muscle of MO offspring, including 8 metabolites shared between both tissues. Male and female-specific metabolites in opposite direction of change were found in liver and skeletal muscle of MO offspring. Several tissue-specific and 4 shared metabolic pathways were identified from these dysregulated metabolites. Interestingly, none of the tissue-specific metabolic alterations reflected in plasma. Our results identify tissue metabolites and pathways in post-pubertal MO offspring in a sex-specific manner. |
