Gene expression of tumor necrosis factor [alpha ] and TNF-receptors, p55 and p75, in nonalcoholic steatohepatitis patients

The main objective of this study was to analyze the pathogenic role of the tumor necrosis factor alpha (TNF-alpha) system in the development of nonalcoholic steatohepatitis (NASH). Fifty-two obese patients were studied. We investigated: (1) the expression of mRNA of TNF-alpha and their p55 and p75-receptors by quantitative reverse-transcriptase polymerase chain reaction (RT-PCR) in hepatic and adipose tissues; and (2) the relationship between...
