Additionally, we found genes highly expressed in breast cancer stroma in the Human Protein Atlas (EGR1, OSBPL8, FAM171A2, FGD6, and CEP131), or likely expressed in fibroblasts (MMP13), that are reported to play a role in breast cancer progression among the most important ones [59,60,61,62,63]. Here, FAM171A2 is linked to breast cancer.
