To investigate the association between TAK1 expression and the survival rates of ovarian cancer patients, Kaplan–Meier survival curves were constructed using the PrognoScan (http://dna00.bio.kyutech.ac.jp/PrognoScan/, accessed on 8 May 2021) and Kaplan–Meier Plotter (ovarian cancer) (http://kmplot.com/analysis/index.php?p=service&cancer=ovar, accessed on 8 May 2021) databases. This evidence concerns the gene MAP3K7 and ovarian cancer.
