Among genetic variants of the gene +276 G>T (rs1501299) and -11377 G>C (rs266729) are the most frequently investigated polymorphisms which were described in the context of genetic conditioning for a predisposition to obesity. However, the information of polymorphisms' potential modifying effect on obesity-related traits achieved through training procedures are still unknown. DNA was extracted from buccal cells donated by the 201 participants and genotyping was carried out using real-time PCR. The genotype distribution was examined in a group of women measured for chosen traits before and after the completion of a 12-week training programme. Our results suggest that the genotypes analyzed individually or in combination can modulate training-induced body mass measurements changes: after the training programme, carriers of rs1501299 T allele and rs266729 C allele were characterized by a greater reduction in fat mass percentage (FM), fat mass, and body mass. Moreover, the polymorphisms were associated with changes in lipid profile in response to training. Additionally, we showed three main effects of genotypes for the FM, LDL-C (rs266729), and TBW (rs1501299). Our study indicate that the both polymorphisms are associated with changes in obesity-related traits in response to 12-week aerobic training programme in Caucasian women. From this evidence, it could be concluded that rs1501299 G and rs266728 G variants may be considered as disadvantageous factor in the context of training-induced effects on body mass traits.
在该基因的遗传变异中,+276 G>T(rs1501299)和-11377 G>C(rs266729)是最常被研究的多态性,它们是在肥胖易感性的遗传条件背景下被描述的。然而,通过训练程序实现的多态性对肥胖相关性状的潜在修饰作用的信息仍然未知。从201名参与者捐赠的颊细胞中提取DNA,并使用实时PCR进行基因分型。在一组女性中检查基因型分布,这些女性在完成12周训练计划前后测量了选定的性状。我们的结果表明,单独或组合分析的基因型可以调节训练引起的体重测量变化:在训练计划后,rs1501299 T等位基因和rs266729 C等位基因的携带者的特征是脂肪质量百分比(FM)、脂肪量和体重有更大程度的降低。此外,这些多态性与训练后血脂谱的变化有关。此外,我们显示了基因型对FM、低密度脂蛋白胆固醇(rs266729)和总体水(rs1501299)的三个主要影响。我们的研究表明,这两种多态性都与白种女性在12周有氧训练计划后肥胖相关性状的变化有关。据此可以得出结论,在训练对体重性状的影响方面,rs1501299 G和rs266728 G变体可能被视为不利因素。
