Abstract
Viruses are one of the main reasons that cause healthy cells to proliferate and become cancerous. Several viruses have been identified as causative factors for various forms of cancer. Tumor occurrence can be caused by viral oncoprotein activity, persistent infection or inflammation. The molecular process is still complicated to be understood. In recent decades, Homo sapiens cell microRNA (hsa-miRNA) has been discovered by small non-coding RNAs that affect post-transcriptional gene expression. hsa-miRNA is a key control factor for several key biological processes and has a much greater impact on the target gene group. even though they occupy a small part of the genome, they play a great role in the development of cancer. Several viruses produce this tiny RNA, which can regulate their gene expression or affect the host's gene expression. A new hypothesis is that Epstein-Barr virus (EBV) is the first cancer causing virus that is found to produce microRNAs (v-miRNAs). In addition, evidence shows that miRNA encoded by EBV contributes to the occurrence and progression of EBV-related malignancies. Generally, these compounds reduce messenger RNA (mRNA) instability, such as genes that regulate tumorigenesis mechanisms like inflammation, cell cycle control, stress response, differentiation, apoptosis, invasion, and immune pathways. Therefore, EBV-miRNAs are important in the complex interaction between host, virus and EBV tumorigenesis. In terms of malignant tumors, the combinatorial process behind EBV-miRNA still needs further study. In this article, we will introduce EBV-miRNA, including the cellular processes affected by the virus, and their ability to promote cancer.
