YB1 is also widely documented as a major player in the regulation of chemoresistance in several types of cancer, including BC (reviewed in [16]), which reenforces the association between YB1 and chemoresistance in AA TNBC tumors, given that AA TNBC are more prone to develop resistance to standards of care chemotherapies than their CA counterparts (reviewed in [16]). The gene discussed is YBX1; the disease is breast cancer.
