Psoralen-Induced Cholestasis via ERK1/2
2026-08-10
Chen et al. show that psoralen and isopsoralen, estrogen-like constituents of Psoraleae Fructus, produce cholestatic liver injury in zebrafish larvae through ERK1/2 activation. By combining estrogenic, hepatobiliary, gene-expression, and pharmacologic rescue assays, the study identifies ERK1/2 as a mechanistically testable node in phytoestrogen-induced cholestasis.
