RNAs are versatile biomolecules and can be coding or non-coding. Among the non-coding RNAs, miRNAs are small endogenous molecules that play important role in posttranscriptional gene regulation. miRNAs are identified in viruses too and involved in down regulation of host genes. Flavivirus family members are classified in to two groups: mosquito-borne flaviviruses (MBFV) and tick-borne flaviviruses (TBFV). Kyasanur forest disease virus (KFDV) found in India in 1957 (Karnataka) relates to TBFV. Virus has been diffuse to new areas in India and needs attention as it can cause severe hemorrhagic fever. Here in this study, we scanned the virus genome for prediction of miRNAs that can inhibit host target genes. VMir, tool was used for extraction of pre-miRNAs. A total of four miRNAs were found and submitted to ViralMir for classification in to real or pseudo. Interestingly, all four pre-miRNAs were classified as real.Eight mature miRNAs were located in pre-miRNAs by Mature Bayes. A total of 539 human target genes has been identified by using miRDB but ANGPT1 (angiopoietin 1) and TFRC (transferrin receptor) genes were screened to play role in hemorrhagic fever and neurological problems. GO analysis of target genes also supported the evidences.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
