as a biomarker for hepatectomy-induced liver injury in patients with hepatocellular carcinoma. It is important to note that detection of miR-122 and other microRNAs in Body fluid like blood can be interfered by heparin contaminated. The commonly used anticoagulant heparin profoundly inhibits the by reverse transcription polymerase chain reaction (RT-PCR) used for microRNA quantification.
