Abstract
Endothelial cells maintain vascular homeostasis through the regulation of permeability and coagulation. Interferon-gamma (IFN-γ), a proinflammatory cytokine released by activated T lymphocytes and natural killer cells, disrupts endothelial junctional integrity, leading to barrier dysfunction. Octreotide (OCT), a synthetic somatostatin analog (SSA), is used to suppress excessive growth hormone secretion and inhibits tumor growth. The present study investigates the potential anti-inflammatory and cytoprotective properties of OCT in IFN-γ-induced endothelial injury. Our observations suggest that OCT suppresses IFN-γ-induced activation of cofilin, MLC2, JAK2, STAT1, STAT3, and P38; as well as endothelial hyperpermeability and ROS generation. Hence, the study supports ongoing efforts aiming to substantiate the protective role of somatostatin analogs in endothelium-dependent disorders, including lung injury and sepsis.
期刊介绍：
The Journal of Biochemical and Molecular Toxicology is an international journal that contains original research papers, rapid communications, mini-reviews, and book reviews, all focusing on the molecular mechanisms of action and detoxication of exogenous and endogenous chemicals and toxic agents. The scope includes effects on the organism at all stages of development, on organ systems, tissues, and cells as well as on enzymes, receptors, hormones, and genes. The biochemical and molecular aspects of uptake, transport, storage, excretion, lactivation and detoxication of drugs, agricultural, industrial and environmental chemicals, natural products and food additives are all subjects suitable for publication. Of particular interest are aspects of molecular biology related to biochemical toxicology. These include studies of the expression of genes related to detoxication and activation enzymes, toxicants with modes of action involving effects on nucleic acids, gene expression and protein synthesis, and the toxicity of products derived from biotechnology.
