Abstract
Chronic liver disease is marked by the gradual destruction of liver tissue over time and replacement of normal liver with nodules of scar tissue. Several liver diseases fall under this category. The end results of the gradual destruction are cirrhosis and fibrosis of the liver. It is estimated that more than 170 million people worldwideare chronically infected with the hepatitis C virus (HCV). Themost important consequence of chronic HCV infection is progressiveliver fibrosis leading to cirrhosis and finally to hepatocellularcarcinoma (HCC), which has significant morbidity and mortality. Many factors, such as alcohol intake, older ageat time of infection, male gender, and co-infection with thehuman immunodeficiency virus or hepatitis B virus acceleratedisease progression. There are two types of cholinesterase enzymes in the blood: acetylcholinesterase, found mainly in red blood cells (RBC) and butarylcholinesterase found in serum or plasma. The general term ChE is used for both enzymes MicroRNA (miRNA) was first discovered in 1993, and was characterized as a small, non-coding RNA miRNA are small RNA molecules which target many mRNA transcripts, leading to their post-transcriptional silencing. Many mRNAs can be silenced by multiple miRNA and miRNA often target more than one mRNA participating in a particular biological function (MicroRNA-132 (miR-132) targets acetylcholinesterase (AChE) and potentiates the cholinergic blockade of inflammatory reactions in cultured cells
