Using the RNA Seq-based gene expression data of the TNMplot online tool (18), we found that the expression of Sdc-1 in 3 paired samples of adjacent normal cervical tissue cervical squamous cell carcinoma and endocervical adenocarcinoma was strongly, yet non-significantly upregulated in the malignant tissue (Figure 1A). Here, SDC1 is linked to cervical squamous cell carcinoma.
