Liver fibrosis is a serious disease that affects around 350–400 million people worldwide. The main approach for fibrosis staging is liver biopsy, which is an invasive procedure that is not endured pretty well by patients. Currently, some serum-based biomarker panels are available for diagnosis and staging of liver fibrosis. Recent high-throughput proteomic studies are also very promising for identification of novel biomarkers for diagnosis and/or treatment of liver fibrosis. We hereby review the application of proteomic profiling studies for identification of fibrosis biomarkers with their advantages and drawbacks.

Non-alcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver diseases with 10–30% prevalence in western countries. The severity of NAFLD ranges from simple steatosis to non-alcoholic steatohepatitis (NASH), cirrhosis, and hepatocellular carcinoma (HCC). However, the wide range of clinical staging of the disease prevents the clear understanding of its pathogenesis. Recently, high-throughput genomic, transcriptomic, and proteomic studies focus on enlightening the complex mechanisms responsible for NAFLD and NASH development. All together these Omics studies, in different cohorts once again, proved that NAFLD and NASH are linked with many complex mechanisms such as accumulation and traffic of various lipids in the liver and activation of inflammation responses. Moreover, some of these studies may have identified potential biomarkers and candidate risky or protective alleles that can be a valuable tool for the assessment of susceptibility and histological severity of NAFLD. Nonetheless, confirmation of these potential biomarkers and candidate genes by multiple Omics tools is required for their clinical application in the diagnosis and treatment of NASH and NAFLD.
