TP73 and brain glioma: Additionally, they determined that TP73‐AS1 may also act as a competing endogenous RNA (ceRNA) to promote HMGB1 expression by sponging miR‐142 to promote the brain glioma growth and invasion.19 CeRNA is a known mechanism of lncRNA; in this mechanism, lncRNA competes for posttranscriptional control by sponging certain relevant miRNAs.20 Previous surveys have confirmed some lncRNA‐miRNA interaction pathways, 21, 22 which provide some theoretical basis for our current research.
