Instead, the authors revealed that an exosomal long noncoding RNA (lncRNA) called lymph node metastasis-associated transcript 2 (LNMAT2) could stimulate human lymphatic endothelial cells (HLECs) tube formation and migration, and thus promote tumor lymphangiogenesis and lymph node metastasis (Chen et al., 2020). The gene discussed is LINC00858; the disease is neoplasm.
