Thymic epithelial tumours are broadly classified into thymomas and thymic carcinomas. Although both tumours occasionally show invasive growth, they exhibit different clinical and biological findings. The oncogene and anti-oncogene in thymic epithelial tumours have not been evaluated fully. We investigated the expression of p53 protein by immunohistochemical(More)
In this study, we analyzed high expression of protein phosphatase (PP) 2A in Alzheimer's disease brain compared to that of the control brain, which result from hyperphosphorylation of histone H1. PP1alpha and PP1gamma1 were slightly expressed in all cases, but there was no relation to the levels of the phosphate in histone H1.
We previously reported that PP1gamma1 is highly expressed in osteosarcoma and chondrosarcoma, and suggested that this protein plays a role in malignancy of osteogenic tumors. In this study, we investigated the correlation of the expression of PP1gamma1 with telomerase activity. PP2A protein was not positive in any of the 5 cases of Ewing's sarcoma, but(More)
