Kaposi's sarcoma-associated herpesvirus (KSHV) is the causative agent of Kaposi's sarcoma (KS), an AIDS-related endothelial cell malignancy that is the most common cancer in central and southern Africa. The KSHV viral G protein-coupled receptor (vGPCR) is a viral oncogene that conveys a survival

Chick embryo cells transformed by either of two strains of Rous sarcoma virus (Bryan high titer or Schmidt-Ruppin) have low levels of alkaline phosphatase activity compared with nontransformed chick embryo cells. Essentially no differences in acid phosphatase activity were observed between these

During the period January 1975 to August 1977, alkaline phosphatase levels in 30 patients with osteogenic sarcoma were closely followed in an attempt to determine if these measurements had clinical value in predicting the course of patients with this disease. Of 17 patients with elevated

The specific activity of alkaline phosphatase was increased in two human osteogenic sarcoma cell lines, SAOS and TE85, after treatment with 1,25 dihydroxy-vitamin D3 (1,25(OH)2D3). Enzyme activity increased when the cells were incubated with concentrations of 1,25(OH)2D3 between 10(-9) and 10(-7) M

The localization of alkaline phosphatase in eight osteogenic sarcomas of osteoblastic. chondroblastic, and fibroblastic type was investigated at the fine structural level using beta-glycerophosphate as substrate and lead as capturing ion. Final product marking localization of alkaline phosphatase

BACKGROUND Magnetic resonance imaging is a pictorial depiction of the patho-anatomy of a bony lesion. As different parts of the tumor in Osteogenic sarcoma concurrently undergo various biological processes i.e. osteoblastic new bone formation, cell death, necrosis, bony destruction and

In chicken embryo fibroblasts, phosphorylation of the 40S ribosomal protein S6 increases during G1 but returns to basal level by mitosis. In contrast, in Rous sarcoma virus (RSV)-transformed fibroblasts, S6 remains highly phosphorylated throughout mitosis. This study investigated the mechanism by

The morphology of 26 cases of osteogenic sarcoma was studied using electron microscopic techniques, and the localization of acid and alkaline phosphatase activity at the ultrastructural level elucidated. Four different cells were present in the tumours: osteoblast-like, fibroblast-like,

Electron microscopic study of osteogenic sarcomas has revealed association of the product of the reaction for alkaline phosphatase with membranous structures. The structural and function polymorphism of osteogenic sarcoma cells is also shown.

OBJECTIVE To study the relationship between the serum levels of alkaline phosphatase (AP) and lactate dehydrogenase (LDH), and the percentage of tumor necrosis (TN) in patients with Ewing´s Sarcoma (ES) . METHODS This is a case series with retrospective evaluation of patients with diagnosis of ES

Tetramisole and its analogues are potent inhibitors of alkaline phosphatase, including isoenzymes of Sarcoma 180/TG which appear to be involved in the mechanism of resistance of this neoplastic cell line to the 6-thiopurines. To determine the requirement for the thiazole ring system of tetramisole

To study the effects of cisplatin [cis-dichlorodiammine-platinum (II)] on tumor cells in the presence or absence of the immune system, animals with ascites sarcoma-180 tumor burden were treated with therapeutic dose levels (9 mg/kg). Similarly, ascites sarcoma-180 cells were maintained in tissue

Membrane vesicles; isolated from normal and Rous sarcoma virus-transformed rat cells, have an associated cyclic-AMP independent kinase that phosphorylates a Mr 37,000 protein in vesicles from normal cells and proteins of Mr 37,000, 50,000, and 67,000 in vesicles from transformed cells. Proteins in

Alkaline phosphatase (AP) has been demonstrated by combined electron microscopy and histochemistry in a transplantable rat osteogenic sarcoma, using a modified Gomori technique (Salomon, 1974). During the early stages of growth of subcutaneously implanted tumors, AP was detected in intracellular

Ewing sarcoma (ES) is a malignant pediatric bone and soft tissue tumor. Patients with metastatic ES have a dismal outcome which has not been improved in decades. The major challenge in the treatment of metastatic ES is the lack of specific targets and rational combinatorial therapy. We recently
