Research progress of FHIT gene and its protein expression in the pathogenesis of lung cancer.

Fragile histidine triad (FHIT) gene is an important tumor suppressor gene,in non-small-cell lung cancer and precancerous lesions its protein deficiency is common,reflecting the FHIT gene is changing in lung cancer occurred in the early molecular events.Ferredoxin in the participation of Fhit protein promotes the electron transport function,and promotes the apoptosis of tumour cells in oxidative stress environment.Fhit protein expression combined platinum enhanced the apoptosis of tumor cell response.With early occuring,high-frequency and facilitate detection,the abnormal changes of FHIT/FRA3B,which take great significance to explain the factors,such as race,genetic polymorphism,geography,environment,respiratory diseases in the pathogenesis of lung cancer. Key words: FHIT gene; Lung neoplasms; Pathogenesis
