IntroductionMany studies suggest that lncRNA has an important role in myocardial hypertrophy (MH) and non-coding RNAs may involve in the regulation of transcription factors during cardiac hypertrophy. We obtained human heart tissues and performed RNA-seq, analyzed the sequencing results using a bioinformatics approach, searched for differentially expressed non-coding RNAs and predicted possible transcription factor targets, expecting to provide new ideas for the prevention and treatment of MH.Method and resultMethod: Myocardial tissues, selected from organ donor patients, were divided into a control group and a hypertrophy group, 3 cases each, for lncRNA and mRNA sequencing. Microarray imaging and data analysis, GO enrichment and KEGG pathway analysis were applied to select differentially expressed genes. The coding-non-coding gene co-expression network (CNC network) was constructed based on the correlation analysis between the differential expressed lncRNA and mRNAs. qRT-PCR and immunohistochemistry verified the analysis results. Result: GO results and KEGG pathway analysis showed that the DEmRNAs were mainly enriched in cytokine-cytokine receptor interaction, phagosome, immune system, and mRNAs are mainly involved in the JAK/STAT signaling pathway, interlukin-6 family signaling. qRT-PCR results showed that p2862(ENST00000500113.1) was significantly downregulated in MH group. In immunohistochemistry, the STAT3 expression was significantly up-regulated in the MH group compared with the normal group, and correlation analysis showed that the relative expression of ENST00000500113.1 was significantly positively correlated with STAT3.ConclusionSeveral lncRNA was demonstrated in the development of cardiomyocyte hypertrophy, and bioinformatics research suggested that lncRNA may be connected to mRNA expression. ENST00000500113.1 may control STAT3 to contribute to progression of myocardial hypertrophy.
