Psoralen-Induced Cholestasis via ERK1/2 in Zebrafish
2026-08-12
Chen and colleagues show that psoralen and isopsoralen, estrogen-like constituents of Psoraleae Fructus, induce cholestatic liver injury in zebrafish larvae through altered estrogen signaling and ERK1/2 phosphorylation. The study connects phytoestrogen exposure with bile acid synthesis and transport defects, while pharmacological rescue supports ERK1/2 as a mechanistically relevant target for further cholestasis research.
