RNA-Seq analysis of porcine islets and pancreas to characterize the differentially expressed genes between higher and lower islet density

Gene expression patterns that form the basis for the observed variation in islet density among porcine pancreata were examined. RNA-Seq analysis was performed to investigate differential gene expression of intact porcine pancreas samples and pure cultured islet samples according to a density of islets. Most prominently upregulated genes in the islet-rich pancreas samples included GP2 and GCG. The mRNA expression of pure islet cell samples from both groups were statistically identical. This transcriptome RNA-Seq analysis showed that pancreatic islet density is associated with GP2 expression. RNA-Seq analysis of 20 porcine islets and pancreas
