ZFAS1 and cervical cancer: High expression of lncRNA KCNMB2-AS1 is positively correlated with poor prognosis of cervical cancer by upregulating the oncogene IGF2BP3, which in turn increases the stability of KCNMB2-AS1 [14]; lncRNA ZFAS1 promotes the metastasis of cervical cancer by suppressing miR-647 mediated by METLL3 [15].
