Besides, the data of qRT-PCR showed that, miR-195-3p expression level was remarkably higher in the NPC tissues of the radioresistance group compared with that in the NPC tissues of the radiosensitive group (Figure 3d), and CDK1 mRNA expression level was negatively associated with miR-195-3p expression level in NPC tissues (Figure 3e). Here, CDK1 is linked to nasopharyngeal carcinoma.
