To ascertain the potential role of CFP1 protein in ovarian cancer, immunohistochemistry was performed on ovarian cancer tissue microarrays (TMAs) to examine the expression of CFP1 protein in normal human ovarian tissues (n = 4), benign tumor (n = 5), and ovarian cancer tissues (n = 158) (Table 1). This evidence concerns the gene CXXC1 and ovarian cancer.
