Recently an outbreak that emerged in Wuhan, China in December 2019, spread to the whole world in a short time and killed >1,410,000 people. It was determined that a new type of beta coronavirus called severe acute respiratory disease coronavirus type 2 (SARS-CoV-2) was causative agent of this outbreak and the disease caused by the virus was named as coronavirus disease 19 (COVID19). Despite the information obtained from the viral genome structure, many aspects of the virus-host interactions during infection is still unknown. In this study we aimed to identify SARS-CoV-2 encoded microRNAs and their cellular targets. We applied a computational method to predict miRNAs encoded by SARS-CoV-2 along with their putative targets in humans. Targets of predicted miRNAs were clustered into groups based on their biological processes, molecular function, and cellular compartments using GO and PANTHER. By using KEGG pathway enrichment analysis top pathways were identified. Finally, we have constructed an integrative pathway network analysis with target genes. We identified 40 SARS-CoV-2 miRNAs and their regulated targets. Our analysis showed that targeted genes including
NFKB1, NFKBIE, JAK1–2, STAT3–4, STAT5B, STAT6, SOCS1–6, IL2, IL8, IL10, IL17, TGFBR1–2, SMAD2–4, HDAC1–6
and
JARID1A-C, JARID2
play important roles in NFKB, JAK/STAT and TGFB signaling pathways as well as cells' epigenetic regulation pathways. Our results may help to understand virus-host interaction and the role of viral miRNAs during SARS-CoV-2 infection. As there is no current drug and effective treatment available for COVID19, it may also help to develop new treatment strategies.
Our findings indicated that the association between FOXP3 rs2232365 polymorphism and knee OA tended to yield negative results but the FOXP3 rs3761548 C allele was associated with elevated risk of OA in Grade 4 knee OA patients in a Turkish population.
Objective:Cardiovascular diseases are the most important cause of mortality worldwide, particularly atherosclerosis. Recently, lncRNAs affecting atherosclerotic progression have been reported in vascular smooth muscle cells, endothelial cells, and monocytes, suggesting that lncRNAs play an important role in atherosclerosis.Methods:In recent clinical studies, nowadays, it was determined that internal mammary bypass grafts are closest to ideal grafts in coronary artery bypass surgery. In this study, we used tissue samples taken from atherosclerotic coronary arteries and the internal mammary artery (IMA) during coronary artery bypass surgery. Using RT-PCR, we investigated the role of two lncRNAs, FENDRR and LincRNA-p21, by comparing their expression levels in coronary artery plaques and normal mammary arteries of 20 atherosclerotic patients.Results:We found that the FENDRR and LincRNA-p21 expressions decreased by approximately 2 and 7 fold in coronary artery plaques, respectively, compared with those in IMA, which is known to have no plaque development.Conclusion:This study was the first to use mammary artery tissues of the same patients as a control and to study FENDRR expression. Our data may provide helpful insights regarding the association of lncRNAs and atherosclerosis.
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.
