Gene Expression-Based Outcome for Breast Cancer Online (GOBO) (http://co.bmc.lu.se/gobo) database showed consistent results, in which the expression of ZMYND10 was lower in tri-negative (ER−/PR−/HER2−) tumors compared to that in other molecular type tumors, and was closely related to tumor grade (Fig. 1c–e). This evidence concerns the gene ERBB2 and breast cancer.
