Targeting of IL-6-Relevant Long Noncoding RNA Profiles in Inflammatory and Tumorous Disease.

Interleukin-6 (IL-6) is a critical cytokine with a diverse repertoire of physiological functions. Dysregulation of IL-6 signaling is associated with inflammatory disorders as well as cancers. However, blockade of IL-6 activity via antibodies directed against the IL-6 signaling pathway may compromise the efficacy of the immune system; therefore, patients may not have a uniformly satisfactory response to treatment. Long noncoding RNAs (lncRNAs) have been discovered to be evolutionary conserved transcripts of noncoding DNA sequences and have emerged as biomarkers with great predictive and prognostic value, further employed as a targeted anticancer therapy. LncRNAs have been recently implicated in the regulation of IL-6-related signaling and function; they are tightly linked to the development of a range of IL-6 dysregulated diseases. Here, we will highlight those lncRNAs involved in IL-6 signaling, with an emphasis on the mechanisms of lncRNAs that interact with IL-6. Targeting of such lncRNAs related to IL-6 regulation could be, in the near future, a promising therapeutic strategy in the treatment of inflammatory- and tumor-related diseases.
