Many types of human malignant tumor have been reported to amplify transforming growth factor-beta 1 (TGF-beta 1) gene and overexpress its protein. However, little work has been done about the content of TGF-beta 1 protein in tissue and blood of patients with malignant tumors. TGF-beta 1 protein of tissue (n = 29) and serum TGF-beta 1 levels in patients with(More)
Transforming growth factor-beta (TGF-beta) comprises a group of multifunctional regulatory proteins, whose effects include angiogenesis. The expression of TGF-beta 1 in gastric carcinomas (70 cases) has been determined and related to pathological features and microvessel count by immunohistochemical staining for TGF-beta 1 and Factor VIII related antigen.(More)
Neovascularization is an important factor in the prognosis of brain tumor and many angiogenetic factors have been evaluated for prognostic significance. Among them, basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF) are known as potent angiogentic factors and mitogens. We evaluated seven cases of grade II brain astrocytoma.(More)
p21 protein has been reported to be a critical downstream effector of p53 and a potent inhibitor of cyclin-dependent kinases. Thus, the p21 gene is thought to play a central role in tumor suppression. In this study we investigated p21 protein expression and mutation in gastric adenocarcinoma. A total of 76 primary gastric carcinoma specimens were(More)
We present a case of retroperitoneal teratoma in a 4-year-old girl in which a Wilms' tumor-like element was predominant, unlike the usual pattern of the immature or malignant teratoma. Mature elements were composed of adipose tissue, neural plexus and ganglia, cartilage, smooth and skeletal muscles, and glandular epithelium of the respiratory and(More)
