摘要


Pyroptosis has been found to be related to diverse ocular diseases, including cataract. Abnormal CRTAC1 expression has been reported to involve in cataract formation by affecting cell apoptosis. Whether CRTAC1 regulates pyroptosis in the formation progress of cataract is completely unknown. Here, we aimed to investigate the regulatory effects of CRTAC1 on pyroptosis and the potential mechanism in the UVB-induced cell damage model. The results showed that the levels of the established pyroptosis markers (NLRP3, active Caspase-1, pro Caspase-1, GSDMD-N, IL-1β and IL-18) were significantly increased in cataract patients. The above pyroptosis markers could be obviously induced by UVB-irradiation in human lens epithelial cells (HLECs), while down-regulation of CRTAC1 significantly reversed the UVB-induced pyroptosis. Up-regulation of CRTAC1 promoted HLECs pyroptosis, while the inhibitor N-acetyl-l-cysteine blocked the effects of CRTAC1 overexpression. In conclusion, our findings further suggested that the prominent role of CRTAC1 in cataract formation.
