BTRC and nasopharyngeal carcinoma: EBV-miR-BART10-3p mimics was transfected into two EBV negative NPC cell lines, HNE2 and 5-8F, which confirmed by Real-time PCR (Figure 3A) and Northern blotting (Figure 3B), that the expression of BTRC was significantly decreased at both the mRNA (Figure 3C) and protein (Figure 3D) levels.
