PELI1 and ovarian cancer: 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).
