Crosstalk between the Notch signaling pathway and long non-coding RNAs.

The Notch signaling pathway has a key role in cellular development and is involved in initiation and progression of cancer by fundamentally influencing cellular processes such as differentiation, proliferation or migration. The pathway is regulated on many stages, generating diverse outcomes depending on cellular context or signaling dose. Recent studies suggest that long non-coding RNAs (lncRNAs), a class of non-coding RNAs deregulated in many cancers, are involved in regulating the Notch pathway activity by modulating the expression of receptors or ligands on transcriptional or posttranscriptional levels. LncRNAs are also downstream targets of Notch signaling and some of these Notch-induced lncRNAs have been reported to be inducers of its oncogenic effects. This cross-talk between Notch signaling and lncRNAs makes those molecules potential biomarkers for Notch signaling activity and interesting therapeutic RNA-based targets in the future.
