Cui et al. (2018) showed that DACH1, which is expressed widely in normal adult tissues and functions as a tumor suppressor in a variety of neoplasms [125], is differentially expressed between MBC and FBC, concluding that the DACH1 gene was downregulated in MBC and HER2 was overexpressed in FBC [107]. Here, ERBB2 is linked to neoplasm.
