Summary of "Serum miR-483-5p and miR-133a as Biomarkers for Diagnosis of Hepatocellular Carcinoma Post-Hepatitis C Infection in Egyptian Patients."

Hepatocellular Carcinoma (HCC) is one of the most common malignant tumors with high incidence and mortality rate. Identification of new, reliable and non invasive biomarkers are important to improve early detection of hepatocellular carcinoma. Circulating micro-RNAs are abundant and play a central role in different biological process of hepatocellular carcinoma. We aimed to evaluate miR-483-5p and miR-133a as potential biomarkers for diagnosis of hepato-cellular carcinoma in cirrhotic patients post chronic hepatitis C virus infection and compare their sensitivity and specificity to currently used alpha fetoprotein test. The study included 20 patients with HCC on top of hepatic cirrhosis post chronic hepatitis C viral infection, 20 patients with hepatic cirrhosis post chronic hepatitis C viral infection, and 20 age and sex matched healthy controls. Serum miRNAs 483 5p and 133a were measured by quantitative real-time polymerase chain reaction (qRT-PCR). Expression levels of miR-483-5p and miR-133a were higher in HCC patients than in patients with liver cirrhosis (P < 0.00).miR-483-5p could predict HCC with sensitivity 100%, specificity 75%, accuracy 0.907, and cut off value > 3.89 while, miR-133a could predict HCC with sensitivity 70%, specificity 90%, accuracy 0.84, and cut off value > 4.79. However, the sensitivity and the specificity of AFP were 80% and 100% respectively. In detecting HCC, combining a-fetoprotein (AFP) and serum miR-483-5p (sensitivity = 95%) and miR 133 a (sensitivity = 90%) were better than AFP alone (sensitivity = 80%). In conclusion; serum miR- 483-5p and miR-133a might serve as noninvasive diagnostic biomarkers for hepatocellular carcinoma. Combination of serum miR-483-5p and miR-133a with AFP might complement the role of AFP in detecting hepatocellular carcinoma.

Medical and Biotech [MESH] Definitions

The type species of the genus ORTHOHEPADNAVIRUS which causes human HEPATITIS B and is also apparently a causal agent in human HEPATOCELLULAR CARCINOMA. The Dane particle is an intact hepatitis virion, named after its discoverer. Non-infectious spherical and tubular particles are also seen in the serum.

An ORTHOHEPADNAVIRUS causing chronic liver disease and hepatocellular carcinoma in woodchucks. It closely resembles the human hepatitis B virus.

The first alpha-globulins to appear in mammalian sera during development of the embryo and the dominant serum proteins in early embryonic life. They reappear in the adult serum during certain pathologic states, primarily hepatocellular carcinoma. They may also be elevated in the amniotic fluid and maternal serum during pregnancy in ANENCEPHALY.

A chronic self-perpetuating hepatocellular INFLAMMATION of unknown cause, usually with HYPERGAMMAGLOBULINEMIA and serum AUTOANTIBODIES.

INFLAMMATION of the LIVER with ongoing hepatocellular injury for 6 months or more, characterized by NECROSIS of HEPATOCYTES and inflammatory cell (LEUKOCYTES) infiltration. Chronic hepatitis can be caused by viruses, medications, autoimmune diseases, and other unknown factors.
