Hepatic differentiation induced by oncostatin M attenuates fetal liver hematopoiesis.
Embryonic liver is a transient site for definitive hematopoiesis. Along with maturation of the bone marrow and spleen, hematopoietic cells relocate from the liver to their final destinations while the liver starts organizing its own structure and develops numerous metabolic functions toward adult. Recently, it was demonstrated that the signal exerted by oncostatin M (OSM) through gp130 plays a ...
متن کاملOncostatin M differentially regulates CXC chemokines in mouse cardiac fibroblasts.
Ischemia-reperfusion injury in the heart is characterized by marked infiltration of neutrophils in the myocardial interstitial space. Studies in human, canine, and murine models have revealed oncostatin M (OSM) expression in infiltrating leukocytes. In an effort to assess possible roles of OSM in the myocardium, we used cardiac fibroblasts (mCFs) isolated from adult mouse heart to determine whe...
متن کاملChanges in the lymph node microenvironment induced by oncostatin M.
Oncostatin M (OM) transforms the lymph node (LN) into a "super lymphoid organ" with 2 striking features: massive thymus-independent T-cell development and major expansion of the memory T-cell pool. We report that T-cell development in the LckOM LN is regulated by a cyclooxygenase-2 (COX-2)-dependent neoangiogenesis involving high endothelial venules (HEVs). That LN HEVs are particularlyrich in ...
متن کاملOncostatin M down-regulates basal and induced cytochromes P450 in human hepatocytes.
The effects of oncostatin M on the expression of different cytochrome P450 (CYP) isozymes has been investigated in human hepatocytes. The dose-response and time-course analyses of effects on CYP1A2 and CYP3A4 isozymes revealed that maximal inhibition was reached after 48 hr of exposure of human hepatocytes to 25 units/ml oncostatin M. Reductions in CYP1A2 and CYP3A4 activity produced by oncosta...
متن کاملOncostatin M regulates endothelin-1 production in human endothelial cells.
The effect of the macrophage- and T-lymphocyte-derived cytokine oncostatin M (OSM) on endothelin-1 (ET-1) production in cultured human umbilical cord vein endothelial cells (HUVEC) was studied. OSM (2.5-10 ng/ml) stimulated ET-1 production and the expression of preproendothelin-1 mRNA. The stimulatory effect of OSM was reversed by anti-interleukin (IL)-6 IgG (33 μg/ml). IL-6 (10 ng/ml) was show...
