Abstract

MicroRNA-122 (miR-122) is the foremost liver-related micro-RNA, but its role in the hepatocyte is not fully understood. To evaluate whether circulating levels of miR-122 are elevated in chronic-HCV for a reason other than hepatic injury, we compared serum level in patients with chronic hepatitis C to other forms of liver injury including patients with acute liver failure and healthy controls. MiR-122 was quantitated using sera from 35 acute liver failure patients (20 acetaminophen-induced, 15 other etiologies), 39 chronic-HCV patients and 12 controls. In parallel, human genomic DNA (hgDNA) levels were measured to reflect quantitatively the extent of hepatic necrosis. Additionally, six HIV-HCV co-infected patients, who achieved viral clearance after undergoing therapy with interferon and ribavirin, had serial sera miR-122 and hgDNA levels measured before and throughout treatment. Serum miR-122 levels were elevated approximately 100-fold in both acute liver failure and chronic-HCV sera as compared to controls (P10 decrease in miR-122 levels ranging from 0.16 to 1.46, after sustained viral response. Chronic-HCV patients have very elevated serum miR-122 levels in the range of most patients with severe hepatic injury leading to acute liver failure. Eradication of HCV was associated with decreased miR-122 but not hgDNA. An additional mechanism besides hepatic injury may be active in chronic-HCV to explain the exaggerated circulating levels of miR-122 observed.
