Difference in the polymorphism of exon 5 +3953C/T of interleukin-1 beta gene between Guangxi Zhuang population and Han population
摘要
Abstract
BACKGROUND: Polymorphism of exon 5 +3953C/T of interleukin-1β (IL-1β) gene is found in some studies. This gene polymorphism is related to stomach cancer, rheumatism, arthritis and other diseases. However, what is the distribution property of genotype of IL-1β gene in Guangxi Zhuang population? OBJECTIVE: To observe the distribution of the polymorphism of exon 5 +3953C/T of 1L-1β gene in Chinese Guangxi Zhuang population and Han population, and compare its distribution with Caucasians and African white people.DESIGN: Contrast observation.SETTING: Department of Histology and Embryology,Youjiang Medical College for Nationalities.PARTICIPANTS: Persons who received the health examination in the Affiliated Hospital of Youjiang Medical College for Nationalities were recruited in the experiment. Among them, 155 were Zhuang nationality, including 80 male and 75 female, aged (37) years, and 195 were Han na tionality, including 100 male and 95 female, aged (38) years. Blood relationship was not found among them,and informed consents were obtained from all the participants.METHODS: This experiment was carried out in the Experimental Center for Medical Sciences,Guangxi Medical University from June 2003 to May 2005. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique was used to detect the polymorphism of exon 5 +3953C/T of IL-1β gene in Guangxi Zhuang population (n=155) and Han population (n=195).Genotype and allele frequency of IL-1β gene of healthy population were directly calculated with counting method, and they were compared between Caucasians and African white people combining with literatures.MAIN OUTCOME MEASURES: Comparison of genotype frequency and allele taking frequency of IL-1β gene (+3953) among different ethnic populations.RESULTS: Subjects who received healthy examination including 155 Guangxi Zhuang nationality and 195 Chinese Han nationality participated in result analysis. ①The frequencies of genotypes and allele of IL-1β gene (+3953C/T) were close between Guangxi Zhuang population and Han nationality (Frequency of genotype CC,CT TT and allele C and T of Zhuang population was 94.8％,5.2％,0,97.4％,2.6％,respectively,and that of Han population was 93.3％,6.7％,0,96.7％,3.3％,respectively,P＞0.05).②There were significant differences in genotype distribution and allele taking frequency of IL-1β gene between Caucasians,African white people and Guangxi Zhuang population,Han population (Frequency of genotype CC,CT TT and allele C and T of Caucasians was 52.2％,43.9％,3.9％,74.1％,25.9％,respectively,and that of African white people was 60.4％,33.2％,6.4％,76.4％,23.6％, respectively, P＜0.01).CONCLUSION: The distribution of polymorphism of exon 5 +3953C/T of IL-1β gene is close between Guangxi Zhuang population and Han population,but significant difference exists in comparison with Caucasians and African white people.关键词
