Additional genes include the Ca2+ binding protein, S100A16, which participates in the EMT in breast cancer [63], the protein kinase FAM20C that promotes proliferation in triple-negative breast cancer, being also a marker of mesenchymal GSCs [64] as well as the LIM Domain Only 2 (LMO2) which is a pro-angiogenic gene [65] and a GSC marker [61]. Here, LMO2 is linked to breast cancer.
