This study investigated the effects of EPI on Zn regulation and autophagy in the pancreas, as well as the modulatory role of\n                    <jats:italic>N<\/jats:italic>\n                    \u2010acetylcysteine (NAC). Rats received EPI (9.6\u2009mg\/kg) by intraperitoneal injection (i.p.) followed 1\u2009h later by NAC (50 or 300\u2009mg\/kg, i.p.). Glucose homeostasis was assessed using the Homeostatic Model Assessment (HOMA\u2010IR), and \u03b2\u2010cell function was assessed using HOMA\u2010\u03b2 levels. Plasma insulin levels, as well as insulin, proinsulin, beclin, autophagy\u2010related proteins (ATG5), Microtubule\u2010Associated Protein 1 Light Chain 3 (LC3), phosphorylated Akt (p\u2010Akt), mechanistic target of rapamycin complex 1 (mTOR1), cleaved caspase\u20103, Zrt\/Irt\u2010like Protein 10 (ZIP10), and the proliferation marker Ki\u201067 in pancreatic tissue, were measured using commercial ELISA kits. Total oxidant status (TOS) and total antioxidant status (TAS) were measured using commercial colorimetric assay kits, and the oxidative stress index (OSI) was calculated. Zn levels in pancreatic tissue and plasma samples were measured using a colorimetric method. Morphological changes in the pancreas were assessed by hematoxylin and eosin staining. As a result, in the EPI group, oxidative stress and ZIP10 levels increased, whereas Zn levels decreased, as well as pancreatic autophagy, proliferation, and insulin synthesis increased. Oxidative stress decreased in both the EN\u201050 and EN\u2010300 groups, with a more pronounced decrease in the EN\u2010300 group. Furthermore, in the EN\u2010300 group, pancreatic Zn, ZIP10, autophagy, and proliferation levels decreased, whereas mTOR1 levels increased. The pancreatic insulin synthesis observed in the EN\u201050 group was not observed in the EN\u2010300 group. In conclusion, the increased autophagy observed in the Epi group may reflect an adaptive response to oxidative stress. The effects of NAC on oxidative stress may be dose\u2010dependent, and high\u2010dose NAC administration may suppress EPI\u2010induced autophagy via mTOR1\u2010mediated signaling. Furthermore, the relationship among Zn levels, autophagy, and insulin synthesis observed in the experimental groups may contribute to a better understanding of EPI\u2010associated diabetogenic alterations.\n
