M⁶A methyltransferase KIAA1429 accelerates oral squamous cell carcinoma via regulating glycolysis and ferroptosis.

ABSTRACT: N⁶-methyladenosine (m⁶A) modification acts as the most prevalent modification on eukaryotic RNA, and its function on oral squamous cell carcinoma (OSCC) is still unclear. Here, the present research aimed to explore the novel function of m⁶A methyltransferase KIAA1429 in OSCC. Results illustrated that KIAA1429 up-regulated in the OSCC samples and cells. Gain/loss functional assays demonstrated that KIAA1429 repressed the ferroptosis of OSCC. Moreover, KIAA1429 positively accelerated the aerobic glycolysis of OSCC, including glucose uptake, lactate production, ATP level and ECAR. Mechanistically, KIAA1429 could install the m⁶A modification on the PGK1 mRNA, thereby up-regulating the methylated m⁶A level. Moreover, m⁶A reader Y
