We then searched Biewenga Cervix database and found that the expression of KMT2A was upregulated in cervical squamous cell carcinoma compared with the cervix uteri (Supplementary Figure 1B), and the differentiation grade of cervical cancer was negatively correlated with KMT2A expression (Supplementary Figure 1C). This evidence concerns the gene KMT2A and cervical squamous cell carcinoma.
