Crosstalk Relationship m6A  →  ncRNA Enhancement
Crosstalk Mechanism m6A regulators directly modulate the functionality of ncRNAs through specific targeting ncRNA
Crosstalk Summary The GAS5 antisense RNA 1 (GAS5-AS1) expression in cervical cancer tissues was markedly decreased when compared with that in the adjacent normal tissues. GAS5-AS1 interacted with the tumor suppressor Growth arrest specific 5 (GAS5), and increased its stability by interacting with RNA demethylase ALKBH5 and decreasing GAS5 N6-methyladenosine (m6A) modification. m6A-mediated GAS5 RNA degradation relied on the m6A reader protein YTHDF2-dependent pathway.
