Abstract:
Objective To explore the relationship between Sirt1 single nucleotide polymorphisms ( rs2236319 ) and chronic obstructive pulmonary disease ( COPD ) susceptibility. Methods The subjects included 149 patients with stable COPD in the First People′s Hospital of Jining outpatient or ward from March 2014 to March 2015, and 160 cases of the same period health check. Sirt1?rs 2236319 genotype distribution frequency was detected by real?time PCR,and the levels of inflammatory factors were compared,including IL?6 and CRP. Results The AA,AG,GG genotype frequency of COPD group were 59. 1%( 88/149) ,35. 6%( 53/149),5. 4%(8/149) respectively,of control group were 45. 0%(72/160),48. 8%(78/160),6. 3%(10/160) respectively,the allele A,G frequency of COPD group were 76. 8%(229/298),23. 2%(69/298) respectively,of control group were 69. 4%( 222/320 ) , 30. 6%( 98/320 ) respectively, there were statistically significant differences between the two groups(χ2=6. 23,6. 06,P<0. 05) . IL?6 and CRP levels were significantly increased in COPD group carrying AA genotype as compared to COPD group carrying AG+GG genotype((10. 30±0. 40) mmol/L,(10. 16±0. 36) mmol/L;(2. 56±0. 20) mg/L,(2. 46±0. 22) mg/L;F=4. 52,8. 04,P<0. 05);There were no significant differences in terms of IL?6 and CRP levels in control group carrying AA genotype as compared to control group carrying AG+GG genotype ( P>0. 05 ) . Both the level of IL?6 and CRP were significantly increased in COPD group carrying AA genotype and AG+GG carriers compared to controls((10. 30 ± 0. 40 ) , ( 9. 88 ± 0. 56 ) mmol/L, ( 10. 16 ± 0. 36 ) , ( 9. 86 ± 0. 57 ) mmol/L;( 2. 56 ± 0. 20 ) , ( 2. 28±0. 25) mg/L,(2. 46±0. 22),(2. 26±0. 26) mg/L;F=34. 52,11. 09,73. 06,19. 38;P<0. 01). Conclusion The polymorphisms of Sirt1?rs2236319 may be an additional risk factor for COPD and associate with inflammatory factors. Furthermore the involvement of rs2236319 in the initiation and progression of COPD may relate to inflammatory processes.
