Ewing's sarcoma (ES) is a highly malignant childhood bone tumor and is considered curable by moderate doses of radiotherapy. The addition of chemical inhibitors of the activity of the nuclear enzyme poly(adenosine diphosphate ribose) [poly(ADPR)] polymerase to ES cells in culture results in
The replication of Sarcoma 180 cells in culture was inhibited by 3,6-dihydroxy-4,5-dimethylphthalaldehyde (HMPA). The inhibition of growth caused by HMPA was evident after treatment of cells with drug for only 15 min. This exposure period caused decreased in (a) cloning efficiency, (b) transport
Musculoskeletal sarcomas (MSS) are a heterogeneous group of malignancies with relatively high mortality rates. The prognosis for patients with MSS is poor, with few drugs inducing measurable activity. Alkylating agents, namely ifosfamide and dacarbazine, which act nonspecifically on proliferating
Sarcoma arises extremely rarely on foreign bodies in man, but is aggressive and often lethal. A coating for implants which would further reduce the risk in man is desirable. The incidence in mice is much greater, and responds to chemical treatment of the implant surface. Coating with histones
OBJECTIVE
The new classification of malignant fibrous histiocytoma leaves only a small group of tumors without further line of differentiation, so-called pleomorphic sarcomas, not otherwise specified (NOS) as a pseudo-entity. This study focused on these tumors and analyzed the association of gene
BACKGROUND
Cancer cachexia is a syndrome manifested by a variety of metabolic abnormalities that include depletion of host energy stores. We studied liver and skeletal muscle high energy phosphate compounds, inorganic phosphorus (Pi), and the energy charge in tumor-bearing (TB), pair fed
UMR-106 rat osteogenic sarcoma cells express two calcium signaling P2 purinergic receptors. One is a P2U receptor with EC50's for adenosine triphosphate (ATP) and uridine triphosphate (UTP) of 2.6 and 2.4 microM, respectively. The other is a novel P2T receptor for adenosine diphosphate (ADP) (EC50
The influence of 9-beta-D-arabinofuranosyladenine (ara-A) and its 5'-triphosphate derivative on programmed synthesis was tested with an intact cell system as well as with isolated enzyme systems. The effect of ara-A was tested in mouse lymphoma cells (L5178Y). The compound reduces cell proliferation
Desmoid-type fibromatoses (or desmoid tumors) are entities of intermediate biological potential and are locally invasive. Radical surgery, as state of the art therapy, is frequently limited by incomplete resections. Hormone modifying therapies are promising but further research is required. Poly
BACKGROUND
Most personalized cancer care strategies involving DNA sequencing are highly reliant on acquiring sufficient fresh or frozen tissue. It has been challenging to comprehensively evaluate the genome of advanced prostate cancer (PCa) because of limited access to metastatic
