We found 3q amplifications as a signature of CC samples, which resulted in SOX2 (3q26.33), TP63 (3q28), SHOX2 (3q25.32), EAF2 (3q13.33) amplifications in CHI-CC; these genes were also proved significantly over-expressed in TCGA-CESC (Figure 3A) as compared with TCGA-UCEC and TCGA-OV. This evidence concerns the gene SOX2 and cervical squamous cell carcinoma.
