چکیده

produced by hepatic stellate cells (HSC). Alpha-smooth muscle actin (α-SMA) and liver enzymes are the two hallmarks of liver injury. Previously, it has been confirmed that berberine (BBR) attenuates liver injury. This study aimed to investigate the protective effect of Poly Lactic-co-Glycolic Acid (PLGA) encapsulated BBR against liver injury. Methods: Nanoprecipitation, encapsulation, and physio-chemical characterization of BBR-PLGA nanoparticles (BBR-PLGA-NP) have been done. The protective effects of BBR-PLGA-NPs and BBR against carbon tetrachloride (CCl4)-treated Wistar rats were investigated. The serum levels of alanine aminotransferase and aspartate transaminase were measured, and the expression level of α-SMA was quantified by qRT-PCR. To evaluate the liver changes, morphological and histological staining was done. Results: BBR-PLGA-NPs markedly reduced serum ALT and AST in rats treated with CCl4. Although the expression level of α-SMA was downregulated in the CCl4-injected rats that were treated with BBR, α-SMA expression in this group was still remarkably higher than the control group. α-SMA mRNA was significantly under-expressed (p < 0.05) by BBR-PLGA-NPs and the hepatic histology revealed BBR-PLGA-NPs made further improvements than free BBR. Conclusion: The use of nanoparticle to encapsulate BBR is a worthy approach to enhance the curative effect of BBR against liver injuries, which donate a safe and effective drug delivery strategy to treat liver injuries
