KCTD11 and neoplasm: Six weeks later, KCTD11‐overexpressing A549 cells showed less progressive tumour growth in the nude mice than in the control group (KCTD11 vs. control group: 0.5836 ± 0.05839 vs. 0.2707 ± 0.03628, p < 0.05, n = 3) (Figure 2G, H and I; Figure S1G), whereas KCTD11‐overexpressing A549 cells showed less metastasis in the nude mice than in the control group (Figure 2J and Figure S1H).
