Impact of bariatric surgery on placental transcriptome. Impact of bariatric surgery on placental transcriptome

In the present study, we sought to understand the impact of bariatric surgery [using vertical sleeve gastrectomy (VSG)] on transcriptome changes in the placenta . Female Adult, Long Evans were fed high fat diet (HFD, #D03082706, Research Diets) for 4 weeks, divided into sham-VSG or VSG groups, and following surgeries one group of sham-VSG and VSG were switched to normal diet (lean), while one sham-VSG group (obese) continued HFD. At gestdational day 18, placenta tissues harvested from pregnant female rats were processed for Affymetrix microarray and transcriptomic analysis performed. Overall design: Three groups of animals: lean sham-VSG (n=6), obese shame-VSG (n=6), and VSG (n=6)
