Supplementary Figure S2A presented a heatmap depicting correlations between PELI1 and 21 m6A regulators across diverse cancer types. Notably, PELI1 expression exhibited significant associations with m6A regulators of ovarian cancer (OV), PRAD, pan-kidney cohort (KICH+KIRC+KIRP) KIPAN and HNSC. To further characterize PELI1 regulation by m6A, we bioinformatically predicted m6A modification sites within the PELI1 gene sequence (Supplementary Figure S2B). This evidence concerns the gene PELI1 and ovarian carcinoma.
