PVT1 and endometrial cancer: For instance, lncRNA TMPO‐AS1 upregulates GLUT1 by directly binding to miR‐140 and miR‐143 in endometrial cancer,[45] while lncRNA MCM3AP‐AS1 acts as a competitive endogenous RNA for miR‐218, enhancing GLUT1 expression in papillary thyroid cancer.[46] Additionally, lncRNA PVT1 binds to miR‐150‐5p, reducing its inhibition of GLUT1 and promoting its expression.[47] The present study identified a novel ceRNA mechanism whereby PDIA3P1 acts as a ceRNA for miR‐152‐3p, reducing the degradation of GLUT1 mRNA by miR‐152‐3p.
