Many studies have shown that NEK2 is found in many human cancers, including non-small cell lung cancer (Zhong et al., 2014a; Zhong et al., 2014b), myeloma (Zhou et al., 2013), ovarian cancer (Liu et al., 2014), BC (Lee and Gollahon, 2013a; Lee and Gollahon, 2013b), prostate cancer (Zeng et al., 2015), colorectal cancer (Neal et al., 2014), malignant peripheral nerve sheath tumor (Stricker et al., 2013), and pancreatic ductal adenocarcinoma (Ning et al., 2014). This evidence concerns the gene NEK2 and ovarian cancer.
