“…Physiologically, these pericytes secrete α-SMA that is responsible for connective tissue formation in response to liver injury, and α-SMA is commonly used as a marker of myofibroblast formation [3,4]. Liver lesions from fibrosis are difficult to cure, but clinical interventions may block further development or reduce related complications [5]. However, current medications for managing hepatofibrosis are limited due to unwanted side effects [6].…”

Background/Aims: Our previous studies have shown that plumbagin effectively inhibits hepatic stellate cell (HSC) proliferation. Thus, plumbagin-mediated anti-fibrotic effects in vivo merit further investigation. Methods: We used rat models to assess the potential benefits of plumbagin against CCl₄-induced liver fibrosis. Results: The results showed that plumbagin lowered the serum concentrations of liver functional enzymes (ALT, AST, ALB, TBIL) in CCl₄-fibrotic rats while reducing inflammatory cytokine levels (IL-6, TNF-a). As reflected in pathological examinations, rats that were administered plumbagin showed decreased collagen markers (HA, LN, PCIII and CIV) in liver tissues and improved hepatocellular impairments. In addition, plumbagin contributed to down-regulating NF-κB and TLR-4 mRNA in CCl₄-lesioned livers. As revealed in the immunohistochemical assay, plumbagin-administered rats showed reduced levels of a-SMA and TNF-a immunoreactive cells in liver tissue. Conclusion: Collectively, these findings offer appealing evidence that plumbagin may serve as an anti-fibrotic medication through inactivating the NF-κB/TLR-4 pathway that is associated with inflammatory reactions, thereby mitigating liver fibrosis.
