Angiotensin II (AngII) is a multifunctional bioactive peptide and previous studies have shown that the renin-angiotensin system (RAS) of both host and tumor are important in tumor growth and angiogenesis in lung cancer. Angiotensin-converting enzyme 2 (ACE2) is a newly identified component of RAS, with 42% amino acid homology to ACE. However, the expression(More)
Angiotensin II (AngII) is a multifunctional bioactive peptide in the renin-angiotensin system (RAS). Angiotensin-converting enzyme 2 (ACE2) is a newly identified component of RAS. The role of AngII and ACE2 in the metastasis of non-small cell lung cancer (NSCLC) and the effects on matrix metalloproteinases (MMPs) are still unknown. In the present study, the(More)
BACKGROUND Systemic corticosteroids (SCS) have been shown to improve the outcome of acute exacerbation of chronic obstructive pulmonary disease (AECOPD). However, the optimal dose remains controversial. OBJECTIVES We performed a meta-analysis to evaluate whether high-dose SCS is better. METHODS We searched PubMed, EMBASE, CPCI-S and CENTRAL databases,(More)
The local renin-angiotensin system (RAS) is one of the crucial components in the tumor microenvironment. Recent evidence suggests that the local RAS plays an important role in tumor metabolism, survival, angiogenesis and invasion processes. Angiotensin-(1-7) [Ang-(1-7)] is an endogenous peptide of the RAS with vasodilator(More)
Angiotensin-converting enzyme (ACE) enhances the proliferation and migration of pulmonary artery smooth muscle cells (PASMCs), which contribute to the pathogenesis of hypoxic pulmonary hypertension (HPH). Previous reports have demonstrated that hypoxia upregulates ACE expression, but the underlying mechanism is unknown. Here, we found that ACE is(More)
UNLABELLED Etiologic diagnoses of lower respiratory tract infections (LRTI) have been relying primarily on bacterial cultures that often fail to return useful results in time. Although DNA-based assays are more sensitive than bacterial cultures in detecting pathogens, the molecular results are often inconsistent and challenged by doubts on false positives,(More)
Hypoxia stimulates the migration of pulmonary artery smooth muscle cells (PASMCs), which contributes to the pathogenesis of pulmonary vessel structural remodeling in hypoxic pulmonary hypertension (HPH). In the present study, we found, using a proteomics-based method, that gelsolin-like actin-capping protein (CapG) and transgelin were preferentially(More)
The T-box transcriptional factor T-bet is crucial in the development, differentiation and function of Th1 cells. It drives Th1 immune response primarily through promoting expression of Th1 hallmark cytokine IFN-γ. Although T-bet was found associated with many immune-mediated diseases such as asthma and systemic sclerosis, little is known about the(More)
As one of the most important endogenous chemotactic factors for neutrophils, the chemokine CXCL8 (IL-8) is involved in the pathogenesis of acute lung injury (ALI) and acute respiratory distress syndrome (ARDS), characterized by massive neutrophil infiltration in the lung. Since neutralization of CXCL8 with polyclonal antibody has been shown to reduce the(More)
Interleukin-17 (IL-17) is involved in protection against extracellular bacteria. However, IL-17 is likely to be deleterious to a host with chronic pulmonary Pseudomonas aeruginosa infection. The role of IL-17 during acute pulmonary P. aeruginosa infection remains unknown. Here, we evaluated the role that IL-17 plays in acute pulmonary P. aeruginosa(More)
