Chen et al. demonstrated in their study that exosomal lncRNA lymph node metastasis-associated transcript 2 (LNMAT2), plays a significant role in promoting tube formation and migration of human lymphatic endothelial cells, as well as enhancing tumor lymphangiogenesis and lymph node (LN) metastasis in bladder cancer (BCa). The gene discussed is LINC00858; the disease is urinary bladder carcinoma.
