MCHR2 and carcinoma of esophagus: Liu et al. identified TLR-related lncRNAs, AP000696.1, LINC00689, LINC00900, and AP000487.1, that are associated with the overall survival of esophageal carcinoma [130], and Chu et al. also reported three lncRNAs (MCHR2, AC011472.4, and AC063944.1) that regulate TLR signaling [131].
