B The length distribution of m 6 A-modified lncRNA transcripts (≤ 3000 bp). C The chromosomal localization of m 6 A-modified lncRNA transcripts. D Volcano plot showed that in 2846 m 6 A-modified lncRNA transcripts, 143 were differentially modified (|log 2 FC|> 0.585, P < 0.05, unpaired t test), and 123 were hypermethylated and 20 were hypomethylated. E The methylation level heatmap of 143 differentially modified lncRNA transcripts. F Volcano plot showed that in 143 differentially modified lncRNA transcripts, 32 were upregulated and 48 were downregulated (|log 2 FC|> 1, P < 0.05, unpaired t test). G The expression level heatmap of 143 differentially modified lncRNA transcripts

Figure Lengend Snippet: Combined analyses of m 6 A modification and expression profiles of 143 differentially m 6 A-modified lncRNA transcripts in LUAD tissues. A The UpSet diagram was used to divide lncRNAs into six categories. B Spearman correlation analyses between the expression levels and methylation levels of 143 lncRNA transcripts in normal tissues (left), tumor tissues (middle), and all tissues (right). A point’s horizontal and vertical coordinates were the mean m 6 A level and mean expression level of a lncRNA transcript in six normal tissues (left), four tumor tissues (middle), and all ten tissues (right), respectively. C Validation of four lncRNAs’ expression levels in six pairs of clinical tissues; GAPDH served as the reference gene. * P < 0.05 and not significant (ns) P > 0.05. Paired t test. D Validation of four lncRNAs’ m 6 A levels in six pairs of clinical tissues by MeRIP-qPCR assays; Input was used as the reference. * P < 0.05, ** P < 0.01 and *** P < 0.001. Paired t test

Figure Lengend Snippet: The screening of prognostic m 6 A-regulated lncRNAs. A The screening criteria of 215 m 6 A-regulated lncRNAs and its expression correlation with m 6 A regulators. B Forest plot of univariate Cox regression analysis of m 6 A-regulated lncRNAs ( P < 0.01). The hazard ratio (HR) value, its 95% confidence interval (CI), as well as the associated P value, were shown. HR > 1 indicated that the lncRNA was a risk factor and its high expression was unfavorable for prognosis, while the high expression of the protective lncRNA of HR < 1 was favorable for prognosis. C The expression correlation between 13 prognostic m 6 A-regulated lncRNAs and m 6 A regulators

Figure Lengend Snippet: Construction of m 6 A-induced ceRNA Network. A The subcellular localization of 43 differentially m 6 A-modified lncRNAs according to RNALoate. B The construction process of the ceRNA network, which consisted of 11 correlative m 6 A regulators, seven differentially modified lncRNAs, 30 sponged miRNAs, and 110 targeted mRNAs. C The diagram of the ceRNA network. The lines connecting m 6 A regulators and lncRNAs represented RNA co-expression in TCGA-LUAD set (| r |> 0.3 and P < 0.001), and the red line represented the lncRNA-m 6 A regulator protein combination detected by CLIP-seq recorded in the POSTAR3 database. D The chart emphasized the dysregulated targeted mRNAs in LUAD, whose numbers of connecting nodes were greater than or equal to 3 in the ceRNA network. FC represented the expression fold change of T-median/N-median. WilcoxTest. *** P < 0.001
