Thrombocytopoietic Properties of Oncostatin

A comparative study on oncostatin M secretion by transplantable melanoma cells with regard to their biological properties and progression.

The authors have studied oncostatin M secretory activity of cells of two lines of transplantable melanoma with different biological properties. The level of OSM in melanoma cells supernatant was determined by ELISA test and OSM bioactivity was measured by using biotest line sensitive to OSM cytostatic activity--A 375 melanoma cells. OSM presence was confirmed in cellular lysates by western blot...

Effects of degree of thrombocytopenia on thrombocytopoietic response.

اثر 6 هفته تمرین هوازی بر حجم تومور و سطح سرمی انکوستاتین-ام در موش‌های مبتلا به سرطان پستان

    Background and Objectives: Breast cancer is a major health concern in women, but it seems that exercise plays an important role in controlling it. Therefore, the aim of the present study was to examine the effects of six weeks of aerobic training on the tumor volume and oncostatin-M serum level in mice with breast cancer. Materials and Methods: This research was an experimental...

Discovery of novel ansamycins possessing potent inhibitory activity in a cell-based oncostatin M signalling assay.

We describe the isolation and characterisation of novel non-benzoquinone ansamycin metabolites related to geldanamycin from a culture of Streptomyces sp. S6699. The compounds possess potent inhibitory activity in a cell-based assay measuring inhibition of oncostatin M signalling in a reporter cell line utilising a secreted placental alkaline phosphatase (sPAP) readout. In this paper we report t...

Oncostatin M is a proinflammatory mediator. In vivo effects correlate with endothelial cell expression of inflammatory cytokines and adhesion molecules.

Oncostatin M is a member of the IL-6 family of cytokines that is primarily known for its effects on cell growth. Endothelial cells have an abundance of receptors for oncostatin M, and may be its primary target. We determined if oncostatin M induces a key endothelial cell function, initiation of the inflammatory response. We found that subcutaneous injection of oncostatin M in mice caused an acu...
