In addition, we observed the expression of the FNDC family members, except FNDC7, in ovarian serous cystadenocarcinoma, the most frequent type of ovarian cancer, using TIMER (see Figure S1, Supplemental Digital Content, http://links.lww.com/MD/I31, which demonstrates the mRNA expression levels of the FNDC family in human cancers from TIMER). This evidence concerns the gene FNDC7 and cancer.
