Method for regulating cell growth, leukocyte differentiation and tumor cell growth using Oncostatin M to stimulate synthesis of IL-6

摘要

The present invention relates to methods of using oncostatin M (OM). In particular, it relates to the use of OM to stimulate interleukin 6 (IL- 6) synthesis in target cells, especially human endothelial cells. The resultant IL-6, in turn, may perform a variety of functions such as cell growth regulation, leukocyte differentiation, and tumor inhibition. Furthermore, the present invention also relates to the use of OM to treat cytopenias, including anemia and thrombocytopoiesis, and to increase tolerance to irradiation and cytotoxic drugs. Therefore, the methods of the invention may have a wide range of applications, including, but not limited to, the inhibition of tumor growth, the treatment of cytopenias, and to increase the tolerance to radio- and chemotherapy. OM may be used in combination with various cytokines, including erythropoietin, colony- stimulating factors, interleukin-3 or thrombopoietin.
