PROX1 and urinary bladder cancer: The lymph node metastasis-associated transcript 2 (LNMAT2) increases lymphatic metastasis in bladder cancer, most likely by binding to the prospero homeobox 1(PROX1) promoter, where it regulates PROX1 transcription by inducing hnRNPA2B1-mediated H3 lysine 4 trimethylation, resulting in lymphangiogenesis and lymphatic metastasis [95].
