====== HNF1A-AS1 ======

[[Long non-coding RNA]]s (lncRNAs) have been proven to exert important functions in the various biological processes of human [[cancer]]s. It has been reported that lncRNA HNF1 homeobox A antisense RNA 1 (HNF1A-AS1) was abnormally expressed and played a role in the initiation and development of various human cancers. In a study, Bi et al. confirmed that the expression level of HNF1A-AS1 was increased in [[glioma]] [[tissue]]s and cells. [[Knockdown]] of HNF1A-AS1 inhibited [[cell proliferation]] and promoted cell [[apoptosis]] in [[glioma]]. Then, they disclosed the [[downregulation]] of [[miR]]-363-3p in glioma tissues and cell lines. The interaction between HNF1A-AS1 and miR-363-3p was identified in glioma cells. Furthermore, an inverse correlation between HNF1A-AS1 and miR-363-3p was observed in glioma tissues. Afterwards, they recognized that [[MAP2K4]] was a direct target of miR-363-3p. The expression of MAP2K4 was negatively correlated with miR-363-3p while positively related to HNF1A-AS1 in glioma tissues. They also found the regulatory effect of HNF1A-AS1 on the MAP2K4-dependent JNK signaling pathway. All findings indicated that HNF1A-AS1 induces the upregulation of MAP2K4 to activate the JNK signaling pathway to promote glioma cell growth by acting as a miR-363-3p sponge
