a. Mortalin protein was detected in tissue microarray of breast lesions by Immunohistochemical staining. b1. Normal breast tissues are negative for Mortalin expression. b2. Positive Mortalin protein expression was detected in the cytoplasm of DCIS. b3. Mortalin protein is strongly positive in breast cancer with lymph node metastasis. b4. Mortalin protein is weak positive in breast cancer without metastasis. b1:×100; b2-b4:×200
