According to a study published by "Journal of ethnopharmacology", the water extract from the seeds of Herpetospermum pedunculosum (HPWE) possesses hepatoprotective effects against acetaminophen-induced liver injury. In vitro experiments demonstrated that HPWE treatment significantly promoted cell viability, decreased ALT/AST levels, and inhibited ROS accumulation. HPWE and Fer-1 also alleviated erasstin-induced cell ferroptosis by upregulating GPX4 and SLC7A11 expression and reducing lipid peroxides production. In vivo experiments showed that HPWE pretreatment in mice significantly alleviated serum ALT/AST levels, decreased necrotic cells and inflammatory cell infiltration, and upregulated GPX4 and SLC7A11 expression. Furthermore, HPWE treatment downregulated Nrf2 and its downstream target genes HO-1 and NQO1 while inhibiting the activation of NF-κB p65 and downregulating the expression of target genes TNF-α and IL-1β.
