Acute lung injury (ALI) is characterized by inflammatory cell infiltration, macrophage activation, and excessive pro-inflammatory cytokine production. Bleomycin (BLM) is widely used to induce acute lung injury (ALI) and fibrosis in murine models. Intratracheally administration of BLM leads to the early stage of inflammatory response and the late stage of collagen deposition. Omentin-1 exerts an anti-inflammatory role in reducing tumor necrosis factor α (TNF-α)-induced cyclooxygenase-2 expression in endothelial cells and attenuating lipopolysaccharide (LPS)-induced ALI. However, the role of omentin-1 in BLM-induced ALI remains unclear. The aim of this study is to examine the effects of omentin-1 on BLM-induced ALI. We found that omentin-1 was decreased in lungs of BLM-induced ALI mice. Omentin-1 overexpression mediated by adenovirus alleviated lung injury and maintained the integrity of the alveolar septa. Omentin-1 overexpression also remarkably decreased the aggregation of neutrophil and macrophages activation, the expression of monocyte chemotactic protein 1 (MCP-1), and down-regulated expression of interleukin 1β (IL-1β) in lungs of BLM-induced ALI mice. Furthermore, we observed that omentin-1 reduced oxidative stress and suppressed the activation of NF-κB pathway in BLM-induced ALI and LPS-induced macrophages activation. Together, our findings indicated that omentin-1 protected mice from BLM-induced ALI may through reducing inflammatory cells recruitment and macrophages activation via alleviation of oxidative stress and NF-κB pathway. Thus, therapeutic strategies aiming to restore omentin-1 levels may be valuable for the prevention of BLM-induced ALI.

UI MeSH Term Description Entries
D008070 Lipopolysaccharides Lipid-containing polysaccharides which are endotoxins and important group-specific antigens. They are often derived from the cell wall of gram-negative bacteria and induce immunoglobulin secretion. The lipopolysaccharide molecule consists of three parts: LIPID A, core polysaccharide, and O-specific chains (O ANTIGENS). When derived from Escherichia coli, lipopolysaccharides serve as polyclonal B-cell mitogens commonly used in laboratory immunology. (From Dorland, 28th ed) Lipopolysaccharide,Lipoglycans

D015398 Signal Transduction The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

D016207 Cytokines Non-antibody proteins secreted by inflammatory leukocytes and some non-leukocytic cells, that act as intercellular mediators. They differ from classical hormones in that they are produced by a number of tissue or cell types rather than by specialized glands. They generally act locally in a paracrine or autocrine rather than endocrine manner. Cytokine
