Construction and characterization of rectal cancer-related lncRNA-mRNA ceRNA network reveals prognostic biomarkers in rectal cancer.

ABSTRACT: Rectal cancer is an important cause of cancer-related deaths worldwide. In this study, the differentially expressed (DE) lncRNAs/mRNAs were first identified and the correlation level between DE lncRNAs and mRNAs were calculated. The results showed that genes of highly correlated lncRNA-mRNA pairs presented strong prognosis effects, such as GPM6A, METTL24, SCN7A, HAND2-AS1 and PDZRN4. Then, the rectal cancer-related lncRNA-mRNA network was constructed based on the ceRNA theory. Topological analysis of the network revealed that the network was maintained by hub nodes and a hub subnetwork was constructed, including the hub lncRNA MIR143HG and MBNL1-SA1. Further analysis indicated that the hub subnetwork was highly related to cancer pathways, such as 'Focal adhesion' and 'Wnt signalling pathwa
