TEAD4 and bladder transitional cell carcinoma: To further validate the metastasis-promoting roles of TEAD4 in BLCA cells, we constructed a lung metastasis model by injecting T24 cells stable transfected with LV-NC or LV-shTEAD4 into the tail veins of nude mice (1 × 106 cells per mouse, n = 6 for each group) (Fig. 9A).
