Relative expression levels of microRNA-122.
The expression levels of hepatic (a) and serum (b) miR-122 in chronic hepatitis C patients with normal and elevated alanine transaminase (ALT) levels were compared with those of healthy controls. Boxes represent range, median and quartiles of the normalized miR-122 expression (∆Cq) levels. Asterisks indicate level of significant difference between analysed groups and are as follows: ****P < 0.0001, ***P < 0.001, **P < 0.01 and *P < 0.05.
