Hypoxia‐induced PGK1 expression promotes esophageal squamous cell carcinoma progression via stimulating MYH9‐mediated GSK3β/β‐catenin signalling

PGK1 promotes ESCC tumourigenicity and migratory capacity by facilitating β-catenin-dependent c-Myc transcription. Under hypoxic conditions, the PGK1‒MYH9 interaction is strengthened, and HIF-1α-mediated transcription increases PGK1 expression, thereby activating the β-catenin/c-Myc signalling pathway. Taken together, PGK1 holds promise as a potential biomarker for predicting postoperative prognosis and recurrence in patients with ESCC.
