Oxidative stress plays an important role in the pathogenesis of chronic obstructive pulmonary disease (COPD) and in the induction of corticosteroid (CS) insensitivity. Chronic ozone exposure leads to a model of COPD with lung inflammation and emphysema. Mitogen-activated protein kinase phosphatase-1 (MKP-1) may underlie CS insensitivity in COPD. We determined the role played by MKP-1 by studyin...
background : breast cancer is a complicated disease and has various clinical manifestations and prognosis. the aim of this study is to make a breast cancer model suitable for basic, preclinical and clinical studies. materials and methods: five virgin bulb/c mice aged 6 weeks and spontaneous murine mammary adenocarcinoma cells (mmac) were used. after anesthesia induction, 1-3 million of mmacs we...
Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide. While the primary risk factor for COPD is cigarette smoke exposure, vitamin D deficiency has been epidemiologically implicated as a factor in the progressive development of COPD-associated emphysema. Because of difficulties inherent to studies involving multiple risk factors in the progression of...
Protease-antiprotease imbalance and oxidative stress are considered to be major pathophysiological hallmarks of severe obstructive lung diseases including chronic obstructive pulmonary disease (COPD) and cystic fibrosis (CF), but limited information is available on their direct roles in the regulation of pulmonary phenotypes. Here, we utilized βENaC-transgenic (Tg) mice, the previously establis...
BACKGROUND There is strong evidence that oxidative stress is associated with the pathogenesis of chronic obstructive pulmonary disease (COPD). The transient receptor potential melastatin-2 (TRPM2) is an oxidative stress sensing channel that is expressed in a number of inflammatory cells and therefore it has been suggested that inhibition of TRPM2 could lead to a beneficial effect in COPD patien...
Chronic obstructive pulmonary disease (COPD) is related to an abnormal chronic inflammatory response of the lung to mainly cigarette smoke (CS) and the disease risk is increased in aged individuals. The source of this chronic inflammation is due to the repeated and progressive activation of immune cells. We hypothesize that in a chronic CS-induced mouse model, the predisposition to COPD pathoge...
Adiponectin is a cytokine with both proinflammatory and anti-inflammatory properties that is expressed in epithelial cells in the airway in chronic obstructive pulmonary disease-emphysema (COPD-E). To determine whether adiponectin modulates levels of lung inflammation in tobacco smoke-induced COPD-E, we used a mouse model of COPD-E in which either adiponectin-deficient or wild-type (WT) mice we...
مقدمه: یکی از شایعترین اختلالات ریوی در بزرگسالان بیماری های انسدادی مزمن ریه (copd) است که شامل برونشیت مزمن و آمفیزم می باشد. شدت این اختلال در تعیین میزان پاسخ به درمان موثر است و لذا امروزه سعی می شود معیارهای مختلفی در جهت درجه بندی شدت بیماری copd استفاده شود که از جمله آنها می توان به معیارهای بالینی ارائه شده توسط american thoracic society (ats) اشاره نمود. شناسایی ارتباطات موجود بین ای...
BACKGROUND Chronic obstructive lung disease (COPD) is a common cause of death in industrialized countries often induced by exposure to tobacco smoke. A substantial number of patients with COPD also suffer from pulmonary hypertension that may be caused by hypoxia or other hypoxia-independent stimuli - inducing pulmonary vascular remodeling. The Ca(2+) binding protein, S100A4 is known to play a r...
Chronic obstructive pulmonary disease (COPD) is characterised by a local pulmonary inflammatory response to respiratory pollutants and by systemic inflammation. Tumour necrosis factor (TNF)-alpha has been implicated in systemic effects of COPD and operates by binding the p55 (R1) and p75 (R2) TNF-alpha receptors. To investigate the contribution of each TNF-alpha receptor in the pathogenesis of ...
