Expression analysis based on TCGA data indicated that HOXA1 was significantly upregulated in most cancer types (Figure 1A), including CESC (cervical squamous cell carcinoma and endocervical adenocarcinoma), LGG (low-grade glioma), GBM (Glioblastoma multiforme), and HNSCC. This evidence concerns the gene HOXA1 and cervical squamous cell carcinoma.
