PDIA3P1 and head and neck squamous cell carcinoma: Epigenetic regulation plays a pivotal role in gene expression, with m6A modification being significantly involved in the modulation of lncRNA expression.[30, 31] In Tan's research, the oncogene PDIA3P1 was identified as an m6A‐related pseudogene, exhibiting substantial m6A peaks and elevated m6A levels in head and neck squamous cell carcinoma.[24] Meanwhile, SRAMP prediction showed that PDIA3P1 enriched multiple specific m6A peaks (Figure9A).
