Indeed, our single-cell RNA-seq (scRNA-seq) study in human islets found that transcripts that regulate alpha-cell maturity, such as ARX and DNMT1 , are differentially expressed across alpha-cell subpopulations, in which pseudotime analysis suggested that certain subpopulations are more mature than others (70), we found that the most immature subpopulation of alpha-cells also exhibited the highest expression of PCSK1 (gene name for PC1/3) ( PCSK1 -expressing alpha-cell subpopulation in response to intra-islet GLP-1R signaling (7478)
GLP-1 (glucagon-like peptide-1 receptor agonists) are prescription medications that mimic a naturally occurring hormone regulating blood sugar and appetite

Cryo-EM structures of class B GPCR reveal the activation mechanism
It often presents as an attack that is indistinguishable from acute pancreatitis, representing paralysis of apical exocytosis in acinar cells, pancreastasis (17, 19, 34), which in animal experiments is tied in with a burst of electron transfer reactions (loosely called free radical activity, FRA) (19, 129)
