Abstract
Cíl: Gen pro adiponektin bývá označován jako kandidátní gen inzulinové rezistence (IR). V naší práci byl sledován možný vztah mezi jednonukleotidovým polymorfi smem (SNP) +276 G > T a markery inzulinové rezistence včetně lipidového a lipoproteinového profi lu u 355 dyslipidemických pacientů lipidové ambulance III. interní kliniky Fakultní nemocnice Olomouc a jejich prvostupňových příbuzných. Metody: SNP genu pro adiponektin byl detekován metodou polymerázové řetězové reakce v reálném čase s hybridizačními fl uorescenčními sondami. Rozdíly mezi genotypy ve spojitých proměnných byly analyzovány metodou ANOVA (upraveno na věk, pohlaví a obvod pasu). Výsledky: Nosiči genotypu GG měli významně vyšší hladiny celkového cholesterolu (GG: 6,54 ± 1,74 mmol/l, GT: 6,18 ± 1,45 mmol/l, TT: 6,25 ± 1,64 mmol/l, p < 0,05) a LDL cholesterolu (GG: 4,12 ± 1,49 mmol/l, GT: 3,78 ± 1,31 mmol/l, TT: 3,70 ± 1,34 mmol/l, p < 0,05) než jedinci s alelou T. Přítomnost alely T na pozici 276 byla u heterozygotů naopak spojena s vyšší koncentrací inhibitoru aktivátoru plasminogenu 1 (PAI-1) (GG: 71,50 ± 41,0 μg/l, GT: 81,0 ± 38,7 μg/l, TT: 70,14 ± 44,4 μg/l, p < 0,05). Závěr: Ve studii byla zjištěna slabá asociace heterozygotů-nosičů T alely polymorfi smu +276 G > T genu pro adiponektin a jedním markerem inzulinové rezistence, avšak nebyl nalezen vztah k sérovému adiponektinu, inzulinu, body mass indexu a dyslipidemickým fenotypům.
Aim: The adiponectin gene has been proposed as a potential candidate gene for IR. We analysed possible relationship between +276 G > T SNP and IR markers together with lipid and lipoprotein profi les in 355 Czech dyslipidemic patients of Lipid Center, University Hospital Olomouc, and their fi rst degree relatives. Methods: The +276 G > T SNP of adiponectin gene was detected by real time PCR method with hybridization fl uorescence probes in LightCycler. Between-genotype differences in continuous variables were analyzed by ANOVA after adjustment for age, sex and waist circumference. Results: Subjects with GG genotype were associated with higher total cholesterol (GG: 6.54 ± 1.74 mmol/l, GT: 6.18 ± 1.45 mmol/l, TT: 6.25 ± 1.64 mmol/l, p < 0.05) and LDL cholesterol (GG: 4.12 ± 1.49 mmol/l, GT: 3.78 ± 1.31 mmol/l, TT: 3.70 ± 1.34 mmol/l, p < 0.05) in comparison with T allele carriers. On the contrary, the presence of T allele in position 276 in heterozygotes was associated with higher levels of plasma inhibitor of activator of plasminogen 1 (PAI-1) (GG: 71.50 ± 41.0 μg/l, GT: 81.0 ± 38.7 μg/l, TT: 70.14 ± 44.4 μg/l, p < 0.05). Conclusion: In this study, the poor association between carriers- heterozygotes of T alelle of +276 G > T polymorphism of gene for adiponectin and one marker of insulin resistance was found. However, no relationship was detected with plasma adiponectin, insulin, body mass index and dyslipidemic phenotypes.
