The results demonstrated that two circRNAs were upregulated (cirR26, and cirR19) and three circRNAs (cirR6, cirR4, and cirR2) were downregulated in ccRCC cell lines in response to altered AR expression (upregulated AR in 786‐O cells and downregulated AR in SW839 cells) by using circRNA‐specific divergent primers (Figure 2E and Table S4). The gene discussed is AR; the disease is nonpapillary renal cell carcinoma.
