WebbMembrane currents and potential were measured by whole-cell patchclamping in isolated α-cells identified by immunocytochemistry. RESULTS--Glucose inhibited glucagon secretion from human islets; maximal inhibition was observed at 6 mmol/l glucose. Glucagon secretion at 1 mmol/l glucose was inhibited by insulin but not by ZnCl[sub 2]. Webb4 maj 2024 · RNA sequencing showed that TAC, and to a lesser extent VCS, decreased the expression of genes that regulate insulin exocytosis, trafficking, and processing, including SYT16, SYT5, PITPNM1, and PAM. Conclusions TAC directly inhibits insulin secretion, likely via transcriptional control of exocytosis machinery.
