Oncostatin M (OSM) also known as Oncostatin M protein or OSM protein is a cytokine with significant roles in inflammation and hematopoiesis. This protein weighs around 28 kDa and is expressed mainly in activated T cells monocytes and macrophages. It interacts with specific receptors on the cell surface to transmit signals that regulate cell growth and function. Oncostatin M is part of the interleukin-6 (IL-6) family contributing to various cellular processes.

Biological function summary

Oncostatin M modulates a range of cellular activities including cell proliferation differentiation and apoptosis. This cytokine affects diverse cell types such as fibroblasts endothelial cells and epithelial cells showing particular influence in processes like tissue remodeling and immune response. It acts as a monomer and does not need assembly into a larger complex to exert its function. Its ability to trigger gene expression differentiates it from other closely related cytokines.

Pathways

Oncostatin M involves itself in significant pathways like the JAK/STAT signaling pathway and the MAPK pathway. Through these pathways it promotes signal transduction essential for immune regulation and cellular response to external stimuli. OSM interacts with proteins like the gp130 receptor a common signaling component for cytokine receptors in its family and influences downstream effectors involved in these pathways.

Oncostatin M associates itself with inflammatory diseases such as rheumatoid arthritis and cardiovascular disorders. Its elevated levels in pathological conditions highlight its role in exacerbating inflammatory responses. In rheumatoid arthritis OSM promotes synovial inflammation while in cardiovascular diseases it may influence vascular remodeling. Connections to inflammatory proteins such as IL-6 further highlight its part in driving disease pathogenesis making it an intriguing target for therapeutic intervention.
