Current therapies for sarcomas are often inadequate. This study sought to identify actionable gene targets by selective targeting of the molecular networks that support sarcoma cell proliferation. Silencing of asparagine synthetase (ASNS), an amidotransferase that converts aspartate into asparagine, produced the strongest inhibitory effect on sarcoma growth in a functional genomic screen of mou...
Mice allografted with different sarcomas, induced by the Schmidt-Ruppin variant of Rous sarcoma virus (RSV-SR), showed a resistance against subsequent isografting of 9 different Rous sarcomas. Transplantation resistance could also be induced by Rous mouse tumor cells x-irradiated with 8000 r or with cell-free tumor extracts, containing no demonstrable virus. No transplantation resistance could ...
Over the last few decades, research on snake venom toxins has provided not only new tools to decipher molecular details of various physiological processes, but also inspiration to design and develop a number of therapeutic agents. Isolated from the venom of Macrovipera lebetina obutusa (MLO), obtustatin represents the shortest known snake venom monomeric disintegrin specific inhibitor of α1β1 i...
ewing’s sarcoma is a round cell malignancy of bone and soft tissue that occurs predominately in adolescents and young adults.it is an uncommon malignancy, but is recognized as the second most prevalent primary bone tumor worldwide. extraosseous ewing’s sarcoma is extremely rare and can affect the skin, soft tissues, or viscera. prognostic and therapeutic features of ewing’s extraosseous tumors ...
Prognosis of patients with lung metastases of soft-tissue sarcoma is still poor. Therefore, novel systemic therapy is needed to improve the survival of soft-tissue sarcoma. In the present study, tumor-targeting therapy with a genetically-modified auxotrophic strain of Salmonella typhimurium, termed A1-R, was evaluated. Mouse models of primary soft tissue sarcoma and spontaneous lung metastasis ...
A case is reported with clear cell sarcoma (CCS) of the hand. Early diagnosis of clear cell sarcoma is always difficult due to its slow growing nature, benign clinical appearance, lack of pigmentation in most cases, and relatively young age of patients which make it to clinically appear as a benign soft tissue tumor. We report a case of clear cell sarcoma of hand in a 56 year old male with a no...
Background: Soft tissue sarcoma is a relatively rare disease from mesenchymal cells . Lung metastases occur in many of the patients with limb sarcoma . The aim of this study was the evaluation of lung metastasis due to limb osteogenic and soft tissue sarcoma in the hospitalized patients at Al-Zahra hospital in Isfahan between 1995 and 2008. Methods: This descriptive cross sectional study wa...
The biologic properties of murine sarcoma viruses in nonproducer and S(+)L(-) cells were compared. Each virus was found to be genetically stable through at least two cycles of rescue and transmission to new cells. There was no evidence for production of a defective murine leukemia virus by S(+)L(-) cells. The results are most consistent with the hypothesis that the sarcoma genome in S(+)L(-) ce...
