Cirrhosis is a complex process that involves a dynamic modification of
liver cell phenotype associated to gene expression changes. This study
investigates the reversing capacity of an adenosine derivative compound
(IFC305) on a rat model of liver cirrhosis and gene expression changes
associated with it. Rats were treated with IFC305 or saline for 5 or 10
weeks after cirrhosis induction (CCl(4) treatment for 10 weeks).
Fibrosis score, collagenase activity and amount of hepatic stellate
cells (HSC, activated and with a lipid storing phenotype) were measured
in livers. In addition, gene expression analysis was performed using 5K
DNA microarrays and quantitative RT-PCR. Treatment of cirrhotic rats
with IFC305 for 5 or 10 weeks compared to saline control, induced: 1)
reduction of fibrosis (50-70%) and of collagen, of alpha-SMA and desmin
proteins, as well as of activated HSCs in liver, 2) increased
collagenase activity and cell number of lipid storing HSC, 3) improved
serum parameters of liver function, such as reduced activity of
aminotransferases and bilirubin. Expression of 413 differential genes,
deregulated in cirrhotic samples, tended to be normalized by IFC305
treatment. Some genes modulated at transcript level by IFC305 were
Tgfb1, Fn1, Col1a1, C9, Apoa1, Ass1, Cps1, and Pparg. The present study
shows that IFC305 reverses liver fibrosis through modulation of
adipogenic and fibrosis-related genes and by ameliorating hepatic
function. Thus, understanding of the anti-cirrhotic effect of IFC305
might have therapeutical potential in patients with cirrhosis.
