The current study investigated the effects of [6]-gingerol, a ginger phytochemical, on the expression of autophagy-related genes and the activation of antioxidative enzymes in the pancreas of mice with cerulein-induced acute pancreatitis. The following were studied: pancreatic edema, ${alpha}$-amylase activity in serum, expression of autophagy genes, activities of antioxidative defense enzymes, such as superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), and the production of lipid peroxidation (LPO). The results revealed that cerulein-induced edema in the pancreas and ${alpha}$-amylase activity in the cerulein group significantly increased compared with that of the control. However, that of the [6]-gingerol pretreated group was significantly decreased compared with that of the cerulein-alone injected group (positive control). There was no significant difference compared with that of control. The expression of autophagy-related proteins, including Beclin-1 and cleaved microtubule-associated protein 1 light chain 3, were significantly increased in the positive control but significantly decreased in the [6]-gingerol-pretreated group. Furthermore, the activities of SOD and GSH-Px in the positive control were decreased compared with those of the control. However, those of the [6]-gingerol pretreated group were significantly increased compared with those of the cerulein-alone group. The mRNA levels and antioxidant enzyme activities were similar. The production of LPO in the cerulein with and without [6]-gingerol groups was increased by 133.1% and 26.3%, respectively, compared with that of the control, whereas that of the [6]-gingerol-pretreated group was significantly decreased by 48.5% compared with that of the positive control. Therefore, [6]-gingerol may be a strong candidate in reducing autophagy and LPO production and in enhancing antioxidative enzyme activities to help prevent acute and chronic pancreatitis.
