 This paper examines the role of microRNAs, mRNAs in viral-related cancers, specifically those caused by Epstein-Barr virus, EBV, and human papilloma virus, HPV. It summarizes the current knowledge on the subject, including the effects of these viruses on the expression of mRNAs and how these changes affect the development of cancer. The authors conclude that mRNAs could serve as useful biomarkers for identifying individuals who are at risk of developing viral-related cancers.
