1 PA treatment significantly induced the expressions of 5-HT2C R and ADAR2 in pancreatic MIN6 beta cells. Palmitic Acid 5-hydroxytryptamine (serotonin) receptor 2C Mus musculus
2 PA treatment significantly induced the editing of 5-HT2C R in pancreatic MIN6 beta cells. Palmitic Acid 5-hydroxytryptamine (serotonin) receptor 2C Mus musculus
3 Moreover, 5-HT2C R edited isoforms displayed reduced endoplasmic reticulum (ER) calcium release and store-operated calcium entry (SOCE) activation, probably through inhibition of stromal interaction molecule 1 trafficking under PA treatment. Palmitic Acid 5-hydroxytryptamine (serotonin) receptor 2C Mus musculus
4 Altogether, our results show that PA-mediated editing of 5-HT2C R modulates GSIS through alteration of ER calcium release and SOCE activation in pancreatic MIN6 beta cells. Palmitic Acid 5-hydroxytryptamine (serotonin) receptor 2C Mus musculus
