MTA1 and nasopharyngeal carcinoma: QRT-PCR and Western blot assays were performed to further explore the interaction between miR-30e-5p and MTA1 of NPC cells, and the data revealed that up-regulated miR-30e-5p obviously decreased the mRNA and protein expressions of MTA1 of the 5-8F cells (Figure 4D,E, P<0.01), while down-regulation of miR-30e-5p obviously increased the mRNA and protein expression of MTA1 of the 6-10B cells (Figure 4F,G, P<0.01).
