For example, Chen et al. (2019) demonstrated that DUXAP8 and DUXAP9 enhanced growth of renal cell carcinoma by binding to miR-29c-3p and leading to upregulation of COL1A1 and COL1A2; Huang T. et al. (2018) suggested that DUXAP8 facilitated progression of renal cell carcinoma by sponging miR-126. Here, COL1A2 is linked to renal cell carcinoma.
