The tobacco-specific carcinogen-operated calcium channel promotes lung tumorigenesis via IGF2 exocytosis in lung epithelial cells

open access: yesNature Communications, 2016
The binding of tobacco-specific carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) to nicotinic acetylcholine receptors (nAChRs) induces calcium signalling.

Alpha-1 antitrypsin deficiency [PDF]

open access: yes, 2001
α-1 antitrypsin is synthesised in the liver and protects lung alveolar tissues from destruction by neutrophil elastase. α-1 antitrypsin deficiency is a common autosomal recessive condition (1:1600 to 1:1800) in which liver disease results from retention ...

Comparison of distinctive models for calculating an interlobar emphysema heterogeneity index in patients prior to endoscopic lung volume reduction [PDF]

open access: yes, 2017
Background: The degree of interlobar emphysema heterogeneity is thought to play an important role in the outcome of endoscopic lung volume reduction (ELVR) therapy of patients with advanced COPD.

Value of metalloproteinases in predicting COPD in heavy urban smokers

open access: yesRespiratory Research, 2020
Background Emphysema in asymptomatic heavy smokers can be detected during CT-scan screening for lung cancer. Metalloproteinases (MMPs) have been found to play a role in the pathogenesis of chronic obstructive pulmonary disease and to possibly serve as ...

The impact of emphysema on surgical outcomes of early-stage lung cancer: a retrospective study

open access: yesBMC Pulmonary Medicine, 2019
Background The presence of emphysema on computed tomography (CT) is associated with an increased frequency of lung cancer, but the postoperative outcomes of patients with pulmonary emphysema are not well known.

Lung volumes identify an at-risk group in persons with prolonged secondhand tobacco smoke exposure but without overt airflow obstruction. [PDF]

open access: yes, 2018
IntroductionExposure to secondhand smoke (SHS) is associated with occult obstructive lung disease as evident by abnormal airflow indices representing small airway disease despite having preserved spirometry (normal forced expiratory volume in 1 s-to ...
