Abstract:
Objective To investigate the association of transforming growth factor (TGF) gene rs1800469 (TGF1-509C/T) and rs1982073 (TGF1+869T/C) single nucleotide polymorphisms (SNP) with susceptibility of lung cancer. Methods The case group consisted of 193 histologically diagnosed lung cancer patients, and control group of 211 controls were selected from cancer-free patients at the same time. The single nucleotide polymorphisms of rs1800469 (TGF1-509C/T) and rs1982073(TGF1+869T/C) were analyzed by real-time fluorescent quantitative reverse transcription polymerase chain reaction method. The demographic characteristics, correlated risk factors of exposure and SNP between 2 groups were compared. Results The genotype distribution frequency of TGF1+869T/C and TGF1-509C/T in control group was accorded with Hardy-Weinberg law (P>0.05). The TT, TC and CC genotype distribution frequency in TGF1+869T/C in case group were 16.1%(31/193), 55.4%(107/193) and 28.5%(55/193), while these in control group were 22.3% (47/211), 50.2% (106/211) and 27.5% (58/211), and there were no statistical differences (P>0.05). The TT, TC and CC genotype distribution frequency in TGF1-509C/T in case group were 28.0%(54/193), 56.0%(108/193) and 16.1%(31/193), while these in control group were 27.0% (57/211), 51.2% (108/211) and 21.8% (46/211), and there were no statistical differences (P>0.05). The allele in rs1800469 (TGF1-509C/T) and rs1982073 (TGF1+869T/C) showed no association with lung cancer (P>0.05). Conclusions TGF gene SNP may not be associated with susceptibility to lung cancer in Han Chinese in North China.
