PDIA3P1 and esophageal squamous cell carcinoma: To test this, MeRIP‐qPCR results demonstrated increased m6A levels of PDIA3P1 in ESCC cell lines (KYSE‐30, KYSE‐150, KYSE‐520, TE‐1, and Eca‐109) compared to the normal oesophageal epithelial cell line HEEC, indicating that m6A contributes to the upregulation of PDIA3P1 expression (Figure 9B).
