Resveratrol protects hepatocytes against hypoxia/reoxygenation injury and its relationship with TLR4/NF-κB pathway
Objective To determine the protective effect of resveratrol (RES) on hepatocytes induced by hypoxia/reoxygenation (H/R) and investigate the molecular mechanism. Methods Before H/R model was established
BRL-3A cells were treated with RES or HTA125 (TLR4 inhibitor). Survival rate and apoptosis were detected in the cells. Alanine transaminase (ALT) and interleukin-1β (IL-1β) in the culture were determined. The mRNA and protein expression levels of TLR4 and NF-κB p65 in the cells were determined by quantitative real-time PCR and Western blotting. Results H/R stimulation decreased cell survival rate and enhanced the apoptosis (P0.01). The expression levels of ALT and IL-1β were enhanced significantly (P0.01)
and the expression levels of TLR4 and NF-κB p65 were markedly increased (P0.01). After pretreatment with RES or HTA125
the cell survival rate was increased (P0.01) while the apoptosis decreased (P0.01). ALT and IL-1β were reduced significantly (P0.01)
and the expression levels of TLR4 and NF-κB p65 were decreased (P0.01). Moreover
RES inhibited the translocation of NF-κB p65 after H/R stimulation in BRL-3A cells (P0.01). Conclusion RES can alleviate the hepatocyte injury induced by H/R
which may be related with inhibition of TLR4/NF-κB signaling pathway.
