The results revealed that both WT and Peli1‐deficient mice showed significant tumor uptake of 18F‐FDG as determined by a PET/CT scan, and there was no significant difference in SUVmax between the two groups (3.67 ± 0.90 vs 3.83 ± 0.33, P = 0.818) (Fig. 2A,B). This evidence concerns the gene PELI1 and neoplasm.
