Figure 1From: YY1 overexpression is associated with poor prognosis and metastasis-free survival in patients suffering osteosarcoma Two comparative examples of YY1 expression in osteosarcomas. A, osteobastic osteosarcoma specimen with 2 as score of immunoreactivity to YY1 at lower magnification (20x); B, the same specimen as in A at higher magnification (100x); C, osteoblastic osteosarcoma specimen with 4 as score of immunoreactivity to YY1 (20x); D, the same osteoblastic osteosarcoma specimen as in C at higher magnification (100x). YY1 protein was localized in nuclei of the cells.Back to article page
