Figure Lengend Snippet: CircRNA microarray and screening process. Results from circRNA microarray and bioinformatics analysis from five paired human RCC vs. RBM tissues were summarized in (A‐D). (A) Box plot demonstrated no significant differences in the distribution of intensity across 10 clinical samples. (B) Scatter plot displayed circRNAs expression correlation between RCC and RBM group. (C) Heat map generated from circRNAs microarray data reflecting circRNAs expression values in RCC and RBM groups. (D) Volcano plot showing DERs data. The red points indicate points‐of‐interest that display both large magnitude fold‐changes (x‐axis) and high statistical significance (‐log10 of p ‐value, y‐axis). The green line shows points above the line having p < 0.05 and points below the line having p > 0.05. This plot is colored such that those points having a fold‐change less than 2 (log2 = 1) are shown in gray. (E) The qRT‐PCR was performed to show 32 selected candidate circRNAs expression levels in cells. (F) The qRT‐PCR was performed on SW839 cells to show effects of manipulating efficiency of selected candidate circRNAs, ciR4#, ciR6#, ciR19#, and ciR26#. (G‐J) Interruption assays revealed that suppressing (G) ciR‐4# (hsa_circ_0001275), (H) ciR‐6# (hsa_circRNA_405974), expression cannot reverse/block the knocked‐down AR‐increased osteolytic formation in SW839 cells (scale bars, 200 μm), increasing (I) ciR‐19# (hsa_circ_0091743) expression, and (J) increasing ciR‐26# hsa_circ_0075303 expression cannot reverse/block the AR‐suppressed osteolytic formation in SW839 cell line (scale bars, 200 μm). For (E‐J), quantitation is at the right, and data are presented as Mean ± SD, ** p < 0.01, *** p < 0.001, **** p < 0.0001. Abbreviation: N.S., not significant
