FMR1 and neoplasm: Bioluminescence imaging results proved that the growth rate of renal tumors in the FMR1-knockdown group was significantly faster than that in FDX1-overexpressing group (Fig. 11A), and in vitro lung imaging results also suggested that the tumor lung metastasis rate in the FMR1-knockdown group was also faster than that in the FDX1 overexpression group (Fig. 11B).
