Long Noncoding RNA UCA1 in Gastrointestinal Cancers: Molecular Regulatory Roles and Patterns, Mechanisms, and Interactions

Figure 1

Biogenesis of lncRNA UCA1. LncRNA UCA1 is produced by transcriptional process mediated by RNA polymerase II from DNA template. It then undergoes special posttranscriptional processing events, including 5′-capping, splicing, polyadenylation, and chemical base modification, to become a mature form.
