TRIM29 and nasopharyngeal carcinoma: To explore the role of TRIM29 in NPC metastasis in vivo, we tested the effect of TRIM29 in a xenograft metastasis model in which TRIM29 knockdown 5-8F cells, TRIM29 overexpression 6-10B cells, and their corresponding control cells were used to generate pulmonary metastases in nude mice.
