HMGA2 and bladder transitional cell carcinoma: In BLCA, linc00355 could act as a sponge of miR-424-5p to modulate high mobility group AT-hook 2 (HMGA2) expression, which could regulate the EMT-related proteins ZEB1, E-cadherin and vimentin and finally contribute to BLCA EMT and lung metastasis [86].
