Figure Lengend Snippet: (A) Experimental setup to detect the deregulated lncRNA in hearts subjected to HF, HF+AAV9-SERCA2a relative to Sham hearts (B) Microarray based profiling of RNA isolated from rat hearts subjected to Myocardial infarction and rescue by Serca2a gene therapy. (C) qRT-PCR of Neat1 from RNA isolated from rat ventricle after MI and MI+Serca2a gene therapy. (D) qRT-PCR for detecting the change in expression of ANP, β-MHC, Neat1, and Neat1.2 in primary neonatal rat ventricular myocytes (NRCM) challenged with 100 µM Isoproterenol for 48 h. * p value < 0.05, ** p value <0.01. t-tests were performed to compute statistical differences between both groups. (E) Neat1 expression levels detected by qRT-PCR and ejection fraction (EF%) throughout heart failure progression (TAC, transverse aortic constriction; n = 5–8). * p value < 0.05, t-tests were performed to compute statistical differences between Sham and TAC. (F) Neat1 expression levels and ejection fraction (EF%) throughout heart failure progression after subjecting mice to 15 mg/kg/day, 30mg/kg/day, and 50 mg/kg/day of isoproterenol for 10 days. * p value < 0.05, ** p value <0.01. t-tests were performed to compute statistical differences between saline and isoproterenol groups. (G) qRT-PCR for detecting the expression of total Neat1 and Neat1.2 in adult mice cardiomyocytes and adult mice non-myocyte fraction.

Article Title: LncRNA Fendrr: involvement in the protective role of nucleolin against H 2 O 2 -induced injury in cardiomyocytes

doi: 10.1080/13510002.2023.2168626

Figure Lengend Snippet: lncRNAs regulated by nucleolin in cardiomyocytes. (A) Heatmap profile of lncRNA microarray analysis. Green to red colors indicate low to high transcriptional levels. The lncRNAs differentially expressed between the two groups were identified through paired t-test P ≤ 0.05 and a fold change (FC) ≥ 2.5; n = 3 independent biological samples for each group. (B) The expression of 15 selected lncRNAs in chip test, where 10 differentially expressed up-regulated lncRNAs (up) and 5 differentially expressed down-regulated lncRNAs (down) were selected. (C) The interactions between nucleolin and lncRNAs were confirmed by RIP and identified via qRT-PCR. *, P < 0.05, vs. IgG group, n = 3. pcDNA3.1, the empty vector served as negative control; pcDNA3.1-Nuc, overexpression nucleolin group. (D) Bioinformatics website predicted Fendrr binding elements with nucleolin.

Article Snippet: Using the Aglient Rat lncRNA microarray V2.0 (Arraystar, Rockville, MD, USA), three sample pairs were prepared for lncRNA microarray analysis in the nucleolin-overexpressing rat cardiomyocyte cell line and control group.
