Impaired autophagy is a critical hallmark of acute pancreatitis (AP).<\/jats:p>\n AIM<\/jats:p>\n To explore the role of the m6A modification of ZKSCAN3 in the regulation of autophagy in AP.<\/jats:p>\n METHODS<\/jats:p>\n The AP mouse cell model was established by cerulein-treated mouse pancreatic acinar cells (MPC-83), and the results were confirmed by the levels of amylase and inflammatory factors. Autophagy activity was evaluated by specific identification of the autophagy-related microstructure and the expression of autophagy-related genes. ZKSCAN3 and ALKBH5 were knocked down to study the function in AP. A m6A RNA binding protein immunoprecipitation assay was used to study how the m6A modification of ZKSCAN3 mRNA is regulated by ALKBH .<\/jats:p>\n RESULTS<\/jats:p>\n The increased expression of amylase and inflammatory factors in the supernatant and the accumulation of autophagic vacuoles verified that the AP mouse cell model was established. The downregulation of LAMP2 and upregulation of LC3-II\/I and SQSTM1 demonstrated that autophagy was impaired in AP. The expression of ZKSCAN3 was upregulated in AP. Inhibition of ZKSCAN3 increased the expression of LAMP2 and decreased the expression of the inflammatory factors, LC3-II\/I and SQSTM1 . Furthermore, ALKBH5 was upregulated in AP. Knockdown of ALKBH5 downregulated ZKSCAN3 expression and restored decreased autophagic flux in AP. Notably, the bioinformatic analysis revealed 23 potential m6A modification sites on ZKSCAN3 mRNA. The m6A modification of ZKSCAN3 mRNA was significantly decreased in AP. Knockdown of ALKBH5 increased the modification of ZKSCAN3 mRNA, which confirmed that ALKBH5 upregulated ZKSCAN3 expression in a m6A-dependent manner.<\/jats:p>\n CONCLUSION<\/jats:p>\n ALKBH5 inhibits autophagic flux through m6A demethylation of ZKSCAN3 mRNA in AP, thereby aggravating the severity of the disease.<\/jats:p>","DOI":"10.3748\/wjg.v30.i12.1764","type":"journal-article","created":{"date-parts":[[2024,3,28]],"date-time":"2024-03-28T05:23:35Z","timestamp":1711603415000},"page":"1764-1776","source":"Crossref","is-referenced-by-count":5,"title":["ALKBH5<\/i>
