MT1JP and metastatic malignant neoplasm in the lymph nodes: The expression levels of lncRNA SNHG6, ARHGAP27P1 (Rho GTPase activating protein 27 pseudogene 1), DANCR (differentiation antagonizing non-protein coding RNA), DGCR5 (DiGeorge syndrome critical region gene 5), MT1JP (metallothionein 1 J, pseudogene), SNHG17, and ZFAS1 (ZNFX1 antisense RNA 1) are closely related to the TNM stage, tumor invasion depth, and lymph node metastasis of gastric cancer [61, 64, 71, 72, 89, 90, 92].
