Increasing evidence has demonstrated that the heat shock protein 70 (HSP70) gene
may be closely associated with tissue fibrosis; however, the association between
HSP70 and liver fibrosis remains to be fully elucidated. The present study
hypothesized that geranylgeranylacetone (GGA) exerts beneficial effects on liver
fibrosis though upregulation of the expression of HSP70. Liver fibrosis was
induced in rats using carbon tetrachloride (CCl4). The rats were subsequently
divided into three groups: Control group, CCl4 model group and CCl4 model + GGA
group. Liver fibrosis in the rats was evaluated using hematoxylin and eosin
staining, Masson's trichrome staining and Sirius red staining. The levels of
serum alanine aminotransferase, aspartate aminotransferase and total bilirubin
were determined using an automated biochemistry analyzer. The levels of total
hepatic hydroxyproline were also determined. The expression levels of ??smooth
muscle actin (??SMA) and transforming growth factor??1 (TGF??1) were determined
using immunofluorescence staining and western blotting, and the protein
expression levels of HSP70 were determined using western blotting. The
CCl4?induced rats exhibited liver fibrosis, increased hydroxyproline content,
impaired liver function, upregulated expression levels of the ??SMA and TGF??1
pro?fibrogenic proteins, and increased expression of HSP70, compared with the
control group. These changes were attenuated by treatment with GGA. These results
demonstrated that GGA exerted beneficial effects in CCl4?induced liver fibrosis
via upregulating the expression of HSP70.
