Recent studies have indicated that ZWINT-1 may function as a biomarker for cancer due to its high expression in some human malignancies such as glioblastoma (Yang et al., 2020), breast cancer (Zhou G. et al., 2020), ovarian cancer (Zhao and Yu, 2020), bladder cancer, lung cancer (Yi et al., 2020), and hepatocellular carcinoma (Xie et al., 2020). The gene discussed is ZWINT; the disease is breast cancer.
