This study was performed to investigate the effect of tumor necrosis factor-α (TNF-α)-tumor necrosis factor receptor (TNFR) signal pathway on autophagy and apoptosis of alveolar macrophages (AMs) in CWP.
This meta-analysis suggested that TNF-a gene -308 G/A polymorphism is associated with increased silicosis and coal workers pneumoconiosis risk in the Chinese population, and further studies in other ethnic groups are required for definite conclusions.
This study was to investigate the association of TNF-alpha gene polymorphism with pulmonary tuberculosis (TB) among patients with coal worker's pneumoconiosis (CWP).
TNFA (-238) gene polymorphism principally affected CWP development and severity (OR = 3.47: 95% CI, 1.12-10.77 and OR = 4.30: 95% CI, 1.25-14.74, respectively) and also risk of CWP (OR = 3.79: 95% CI, 1.37-10.46).
We hypothesized that TNF-alpha promoter polymorphisms associate with lung responses to environmental exposure in coal worker's pneumoconiosis (CWP) patients.
To assess whether polymorphisms within the TNF promoter gene are associated with susceptibility to coal workers' pneumoconiosis (CWP), the DNA of 78 coal miners was typed for G-to-A transitions at positions -238 and -308.
Moreover TNF and IL-6 expression was associated with the presence of coalmine dust particles, suggesting a direct role of mineral particles in the cytokine production and development of pneumoconiotic lesions in CWP.
