Galactose protects pancreatic acinar cells from cerulein induced damage by regulating FGF21 and Klotho

To investigate the effect and mechanism of galactose on cerulean-induced pancreatic acinar cell injury. Acute pancreatitis cell injury model was established by arbusin-induced pancreatic acinar cell AR42J injury; galactose (25, 50, 100 mmol / L) was used to treat the injured cells, and the optimal concentration was 50 mmol / L; cell counting kit (CCK-8), enzyme linked immunosorbent assay (ELISA) to detect cell survival rate and necrosis rate; flow cytometry and Western blotting (Western blot) to detect cell apoptosis and autologous phage-related gene (Beclin1) and microtubule-associated protein 1 light chain 3 (LC3), apoptosis-related protein B-cell lymphoma / leukemia-2 (Bcl-2), Bcl-2-related X gene (Bax), and fibroblasts Expression of growth factor 21 antibody (FGF21) and anti-aging gene Klotho. A pancreatic acinar cell injury model was successfully established with cerana (100 nmol / L); galactose (25, 50, 100 mmol/L) In a concentration-dependent manner, the inhibitory effect of ceriferin on AR42J injury was inhibited at an optimal concentration of 50 mmol / L. Compared with the ceriferin group, the apoptosis rate of AR42J cells in the galactose group was significantly reduced. table Significantly increased, Bcl-2, FGF21 and Klotho protein expression was significantly increased, Bax protein was significantly decreased; the FGF21 inhibitor can be significantly reduced on galactose these caerulein-induced AR42J cells. Galactose can inhibit the apoptosis and autophagy of pancreatic acinar cells induced by cerana, and its potential mechanism is to up-regulate FGF21 and Klotho, providing a new potential drug for the treatment of acute pancreatitis.
