文题释义:
基因多态性:是指在一个生物群体中,同时和经常存在两种或多种不连续的变异型或基因型(genotype)或等位基因(allele),从本质上来讲,多态性的产生在于基因水平上的变异,一般发生在基因序列中不编码蛋白的区域和没有重要调节功能的区域,通常分为3大类:DNA片段长度多态性、DNA重复序列多态性、单核苷酸多态性。
烟酰胺N-甲基转移酶基因多态性与运动能力的关联:烟酰胺N-甲基转移酶基因表达水平与机体能量代谢高度相关,其DNA序列上单核苷酸变异引起的多态性位点多达几百个,某些多态性变异对机体烟酰胺N-甲基转移酶基因的活性或表达水平具有明显的调控作用。多态性可以通过调控烟酰胺N-甲基转移酶基因的表达水平影响机体能量代谢,与人体运动能力具有密切联系。
摘要
背景:
研究证实,烟酰胺N-甲基转移酶基因(nieotinamideN-methyl-transferase,NNMT)多态性与人体有氧运动能力相关。手球是一种混氧运动,比赛或平时训练中无氧运动占一定比例,主要进行有氧运动。   
目的:探讨NNMT基因单核苷酸多态性位点rs2256292与手球运动能力的关联。
方法:采用PCR-LDR方法检测28名中国国家青年男子手球队运动员(实验组)和53名普通男学生(对照组)NNMT基因单核苷酸多态性位点rs2256292,测试相对最大摄氧量VO2 max和骨骼肌百分比、体脂百分比身体成分指标。
结果与结论:①实验组G等位基因和GG基因型频率显著高于对照组(P < 0.05);②在28名运动员中,基因型GG组相对VO2 max明显高于基因型CG组(P < 0.05);在53名普通学生中,基因型GG组、基因型CG组及基因型CC组间相对VO2 max无差异;③在28名运动员中,基因型GG组骨骼肌百分比高于基因型CC组、基因型CG组(P < 0.05);在53名普通学生中,基因型GG组骨骼肌百分比高于基因型CG组(P < 0.05);④在28名运动员中,基因型GG组、基因型CG组及基因型CC组间体脂百分比无差异;在53名普通学生中,基因型GG组、基因型CG组及基因型CC组间体脂百分比无差异;⑤结果表明,NNMT基因单核苷酸多态性位点rs2256292与手球运动能力明显相关,运动员更倾向于G等位基因,基因型GG携带者运动能力较强。

Abstract:

BACKGROUND: Studies confirm that niacinamide N-methyl transferase gene (NNMT) polymorphism is associated with human body aerobic exercise capacity. Handball is a kind of mixed oxygen sports, accounting for a proportion of anaerobic exercise in competition or peacetime training, mainly in aerobic exercise.
OBJECTIVE: To explore a NNMT gene single nucleotide polymorphism locus rs2256292 associated with the athletic ability of handball players.
METHODS: The NNMT genetic polymorphism locus rs2256292 in 28 athletes from Chinese national male handball team (experimental group) and 53 male students (control group) was tested by polymerase chain reaction-ligase detection reaction. The relative VO2max and body constituents index of skeletal muscle, body fat percentage were also tested.
RESULTS AND CONCLUSION: Frequencies of G allele and GG genotype in the experimental group were significantly higher than those in the control group (P < 0.05). Among the 28 athletes, the relative VO2max in the GG genotype group was higher than that in the CG genotype group (P < 0.05). Among the 53 general students, there were no differences in relative VO2max among genotypes. Among the 28 athletes, the skeletal muscle percentage in the GG genotype group was significantly higher than that in the CC and CG genotype groups (P < 0.05). Among the 53 general students, the skeletal muscle percentage in the GG genotype group was significantly higher than that in the CG genotype group (P < 0.05). In addition, there were no differences in the body fat percentage among genotypes in athletes or general students. These results suggest that the NNMT genetic polymorphism locus rs2256292 is significantly correlated with the athletic ability of handball players, with the athletes being more likely to have G allele and carriers of GG genotype having stronger athletic ability.
