Comprehensive identification of RNA transcripts and construction of RNA networks in coronary arterial calcification. Comprehensive identification of RNA transcripts and construction of RNA networks in coronary arterial calcification

Here, we report a comprehensive analysis of dysregulated mRNAs, lncRNAs, miRNAs and circRNAs in peripheral blood of CAC patients with high-throughput RNA sequencing. We mapped about 50 million sequence reads per sample to the human genome. GSEA analysis showed that these dysregulated RNAs correlate with several critical biological processes such as RNA modification, and RNA metabolism. RT-qPCR (SYBR Green assays) with more clinical CAC samples were used for the validation of some dysregulated RNAs. We have also constructed the co-expression network between lncRNA and mRNA, and established the circRNA-miRNA-mRNA in CAC based on this data. This study provides valuable insights to understand the RNA involvement and regulation in CAC, assisting future CAC investigations.
