TRIM29 and nasopharyngeal carcinoma: Interestingly, the protein expression level of TRIM29 is obviously higher in 5-8F cells with high metastatic potential than in 6-10B cells with low metastatic potential, and also higher in the poorly-differentiated CNE2 cells than in the well-differentiated CNE1 cells, suggesting that TRIM29 may be involved in NPC progression.
