Transcriptome profiling reveals significant changes in the gastric muscularis externa with obesity that partially overlap those that occur with gastroparesis

The goal of the current study was to identify changes in gene expression in the stomach muscularis that may be contributing to altered gastric motility in gastroparesis and obesity. Overall design: Stomach muscularis biopsies were obtained from human subjects with low BMI and normal gastric motility (low BMI control, n=6), subjects with high BMI but normal gastric motility (high BMI control, n=6), subjects with low BMI and gastroparesis (low BMI gastroparesis, n=6) and from subjects with high BMI and gastroparesis (High BMI gastroparesis, n=4). RNA was isolated and subjected to whole transcriptome sequencing.
