Identification of galangin as a therapeutic candidate for primary biliary cholangitis via systematic druggable genome-wide Mendelian randomization analysis and experimental validation

By integrating systematic druggable genome-wide MR analysis with experimental validation, this study identified 15 druggable genes associated with PBC. More importantly, it identified GAL as a therapeutic candidate for PBC, with its effects potentially mediated by the ADORA2A target. These findings provide novel therapeutic targets and drugs for PBC. Future research will focus on validating the functions of these druggable genes and elucidating the mechanistic pathway of the galangin-ADORA2A interaction, laying a more solid and comprehensive theoretical and practical foundation for PBC treatment.
