Depletion of endogenous STING in RCC and non‐RCC cell lines by three independent shRNAs (Figure 1F) led to reduced ability of colony formation (Figure 1G,H) and decreased 3D anchorage‐independent growth in vitro (Figure 1I,J) with the only exception of HEK293 cells (Figure 1G,H). This evidence concerns the gene STING1 and renal cell carcinoma.
