COL11A1 participates in the progression of RCC through the SNHG12/miR-200c-5p/COL11A1 axis. (A) COL11A1 expression levels were discovered to be regulated by SNHG12 in a miR-200c-5p-dependent manner. COL11A1 expression levels were analyzed using RT-qPCR. (B) Expression levels of SNHG12 and COL11A1 were analyzed using RT-qPCR following the transfection with pcDNA3.1-SNHG12 or si-COL11A1, respectively. (C) miR-200c-5p inhibitor rescued COL11A1 expression levels downregulated by si-SNHG12. (D) Flow cytometric analysis of apoptosis was performed in cells co-transfected with pcDNA3.1-SNHG12 and si-COL11A1. (E) Quantification of the apoptosis results were shown as bar plots. (F) Cell viability was determined using an MTT assay following the transfection with pcDNA3.1-SNHG12 + si-COL11A1. *P<0.05. SNHG12, small nucleolar RNA host gene 12; COL11A1, collagen type XI α1 chain; miR, microRNA; NC, negative control; si, small interfering RNA; RT-qPCR, reverse transcription-quantitative PCR; 7-AAD, 7-Aminoactinomycin D.
