UCA1 and cancer: Long noncoding RNAs (lncRNAs) can form complex networks by the interactions with microRNAs (miRNAs), messenger RNAs (mRNAs), and proteins, and play pivotal roles in different cancers.5 LncRNAs are involved in the progress of OSCC through affecting various aspects of cellular homeostasis.6 LncRNA urothelial cancer‐associated 1 (UCA1) exerts critical effects on various cancers.
