AK4 Promotes the Progression of HER2-Positive Breast Cancer by Facilitating Cell Proliferation and Invasion

Figure 1

AK4 was highly expressed in human HER2-positive breast cancer tissues. (a) IHC assays were performed, and the representative photographs of AK4 expression levels in HER2-positive breast cancer tissues were detected and shown (×100 and ×200 magnification, respectively). (b) IHC staining showed AK4 expression levels in adjacent nontumor tissues (×100 and ×200 magnification, respectively).
