Background:
Coal workers' pneumoconiosis (CWP) is characterized by progressive pulmonary fibrosis. Inflammation is crucial in the host response to silica and it contributes to pulmonary fibrosis. Cyclooxygenase-2 is involved in this process. The association between single-nucleotide polymorphisms in cyclooxygenase-2 gene with pneumoconiosis risk was investigated.
Methods:
An association study was conducted by analyzing two single-nucleotide polymorphisms of cyclooxygenase-2 (rs689466 and rs20417) in a case-control study involving 90 patients and 90 healthy individuals (controls). Genotyping was performed by the TaqMan method.
Results:
The rs689466 AG and GG and rs689466 GC polymorphisms were significantly less frequent in patients than in controls. Cyclooxygenase-2 rs689466 and rs20417 variant genotypes exhibited 21% and 12% decreased CWP risk, respectively.
Conclusion:
Cyclooxygenase-2 rs689466 and rs20417 polymorphisms were associated with CWP risk.
