(A) QRT-PCR was used to analyze the correlation between miR-126-5p and PRNCR1. (B) The correlation between miR-126-5p and MTDH was identified using correlation analysis. (C) QRT-PCR was employed to verify the relationship between MTDH and PRNCR1. (D) After transfection with si-NC, si-PRNCR1, si-PRNCR1+anti-NC, si-PRNCR1+anti-miR-126-5p, the protein expression of MTDH was evaluated utilizing Western blot. *P<0.05.
