The relationship between AATF protein expression in the CPTAC database and the pathological stage of 8 tumors was analyzed on the UALCAN website, of which 7 tumors had differences in different pathological stages, including breast invasive carcinoma (BRCA), colon adenocarcinoma (COAD), kidney renal clear cell carcinoma (KIRC), head and neck squamous cell carcinoma (HNSC), lung adenocarcinoma (LUAD), ovarian serous cystadenocarcinoma (OV), and uterine corpus endometrial carcinoma (UCEC) (P < 0.05, Figure 3(b)). Here, AATF is linked to invasive breast carcinoma.
