TLR5 and cancer: Most interestingly, more and more published studies have suggested that some established lncRNAs can regulate TLR signaling transduction and the relevant immune function in cancer, autoimmune and inflammatory disorders by acting as ceRNAs, such as networks of lncRNA SNHG1-miR-140-TLR4, lncRNA X-miR-154-5p-TLR5, and lncRNA Gm6135-miR-203-3p-TLR4 (38–41).
