For example, GRB7 overexpression has been linked to increased tumor proliferation and migration in cervical and ovarian cancers (Wang et al., 2010; Zhao et al., 2017) and enhanced cell invasion in breast cancer and esophageal adenocarcinoma (Gotovac et al., 2020; Chu et al., 2010). This evidence concerns the gene GRB7 and breast cancer.
