Rs and enhancers), untranslated regions (UTR) and telomeres [18,19] and kind RNA NA, RNA NA or RNA rotein interactions to execute their particular activities. lncRNAs are reported to function as guide, scaffold, signaling and decoy RNAs [20] (Figure 1). Guide lncRNAs, which include X inactive-specific transcript (Xist) and Hox transcript antisense RNA (HOTAIR), regulate gene expression in cis or in trans through recruiting chromatin-modifying enzymes to particular genomic regions [21,22]. As scaffold lncRNAs, HOTAIR or metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) recruit numerous proteins to type ribonucleoprotein complexes and modulate gene expression [23]. Various signaling lncRNAs, like HOTAIR and regulator of reprogramming lincRNA (linc-ROR), act as molecular signals and integrate with specific signaling pathways [24] whilst the decoy lncRNAs, for example, P21-associated ncRNA DNA harm activated (PANDA) and MALAT1, sequester transcription aspects away from chromatin and regulate gene expression. Functional small peptides encoded by lncRNAs happen to be identified that happen to be involved in cellular functions [25]. Increasing evidence suggests that the stability of lncRNAs is regulated by miRNAs. However, lncRNAs can act as competing Somatostatin Receptor Compound endogenous (ce) RNAs and sequester certain miRNAs away from their target genes, consequently inhibiting miRNA-mediated functions [26]. Interplay patterns between lncRNAs and miRNAs seem to become important events in cancer progression. Emerging data help the involvement of lncRNAs in tumor-stroma communication, a potentially critical occasion in cancer progression. Recently, Sang et al. [27] demonstrated that lncRNA for calcium-dependent kinase activation (CamK-A) is upregulated in quite a few cancers andInt. J. Mol. Sci. 2018, 19,three ofInt. J.
