ALKBH5 induces posttranscriptional activation of PER1 to inhibit PC progression in an m6A-YTHDF2-dependent manner. ALKBH5 loss that abrogates mRNA demethylation leads to an upregulation of PER1 m6A levels in PC cells. Then, degradation of PER1 mRNA occurs on the basis of the m6A-YTHDF2 interaction. PER1 downregulation results in the inhibition of ATM phosphorylation and inactivation of the ATM-CHK2-P53/CDC25C pathways. G2/M arrest in PC cells was suppressed as a result. The PER1-related P53 downregulation and P53-dependent transcriptional inactivation of ALKBH5 indicates a feedback loop underlying the progression of PC
