Compared with patients ≥65 years of age, the FOXQ1 expression level in patients <65 years of age was higher in bladder urothelial carcinoma, breast invasive carcinoma, liver hepatocellular carcinoma, ovarian serous cystadenocarcinoma, and uterine corpus endometrial carcinoma and lower in kidney renal papillary cell carcinoma and lung squamous cell carcinoma (Figure 6A). This evidence concerns the gene FOXQ1 and ovarian serous cystadenocarcinoma.
