CDK1 and nasopharyngeal carcinoma: To further probe the effects of miR-195-3p and CDK1 on NPC cell growth, apoptosis, cell cycle and radiosensitivity, NC mimics, miR-195-3p mimics and miR-195-3p mimics + CDK1 overexpression plasmids were transfected into 5–8 F-R and 6–10B-R cells, respectively, and qRT-PCR validated the successful transfection (Figure 4a).
