MicroRNA-221: A Fine Tuner and Potential Biomarker of Chronic Liver Injury

Circulating microRNA-122 as a potential biomarker for liver injury.

Liver-specific microRNA-122 (miR-122) is involved in the replication of hepatitis C virus (HCV) and its potential as a target for antiviral intervention was recently assessed. However, the use of circulating miR-122 in the evaluation of liver function has never been reported. In the present study, changes of serum miRNA levels were first evaluated in acute human hepatotoxicity due to paraquat e...

Role of microRNA as a biomarker in Alzheimer’s disease

Introduction: MicroRNAs are small, non-coding, and protected RNA molecules that regulate gene expression after transcription by mRNA degradation or inhibition of protein synthesis. The function of these molecules is critical to many cellular processes, including growth, development, differentiation, homeostasis, apoptosis, aging, stress resistance. In addition, some diseases including cancer, a...

Circulating Liver-Specific miR-122 as a Novel Potential Biomarker for Diagnosis of Cholestatic Liver Injury

BACKGROUND Circulating microRNA-122 (miR-122) has been increasingly reported to be a potential biomarker for drug-, viral-, alcohol- and chemical-induced liver injury. The present study was initiated to determine the potential of circulating miR-122 as a biomarker for cholestatic liver injury. METHODS Both bile-duct ligation (BDL) mice and patients with biliary calculi were employed as choles...

MicroRNA Expression Profiling in PBMCs: A Potential Diagnostic Biomarker of Chronic Hepatitis C

The expression levels of miR-16, miR-193b, miR-199a, miR-222, and miR-324 in PBMCs were significantly higher in CHC patients compared with healthy controls and significantly different between CHC patients with HCV genotype 1 (GT-1) and non-genotype-1 (non-GT-1). Multivariate logistic regression analysis also showed that patients with high expression levels of the six target miRNAs had an approx...
