In order to detect DOCK4 expression pattern among different tumors, the webserver of UALCAN (http://ualcan.path.uab.edu/analysis.html) was employed to present DOCK4 gene expression pattern among 33 tumors with TCGA RNA-Seq expression data (Figure 3(f)), which indicated that DOCK4 gene does not have low expression in ovarian cancer. This evidence concerns the gene DOCK4 and ovarian cancer.
