Pa induced islet er stress
WebApr 24, 2024 · In contrast, we propose that SOCE is not involved in the triggering or modulation of glucose-induced Ca 2+ oscillations in untreated control islets, but it is activated by ER stress, resulting in the appearance of Ca 2+ oscillations under subthreshold glucose conditions (5 m m glucose) by virtue of this abnormal triggering mechanism, … WebNov 21, 2024 · Palmitic acid (PA) significantly induces the ER stress in the primary EECs and promotes the EEC-derived exosome biogenesis in EECs. A Co-immunofluorescent staining of cytokeratin 8 (red) and vimentin (green) evaluated primary EECs purity. B-D PA significantly induced ER stress based on the upregulation of PERK and IRE1α in the EECs.
