BCRP expression was positively related to mPRα and p-Akt1 S473 in breast tissue. Representative BCa specimens positive for mPRα, p-Akt1 S473, and BCRP, as detected by IHC. Photographs were taken at ×400 magnification. Invasive BCa positive for mPRα (left), p-Akt1 S473 (middle), and BCRP (right). Note that in BCa, mPRα and BCRP were detected at the membrane and/or in the cytoplasm, while p-Akt1 S473 was mainly detected in the cytoplasm.
