Polymorfismus rs1801282 v genu PPARγ ve vztahu ke koncentraci a složení mastných kyselin u českých adolescentů / Polymorphism rs180128 in the PPARγ gene in relation to the concentration and composition of fatty acids in Czech adolescents

Hovhannisyan, Milena January 2020 (has links)
The prevalence of obesity and type 2 diabetes in the adolescent population has been steadily rising. According to the previous studies, the rs1801282 (Pro12Ala) polymorphism in the PPARγ gene is connected to the development of obesity, hypertension, insulin resistance, hyperlipidaemia, and other metabolic complications of type 2 diabetes. Data collection was undertaken as part of the COPAT project (Childhood Obesity Prevalence and Treatment). A sample of 2246 Czech adolescents aged 13-17 was genotyped using RT-PCR and subjected to further anthropometric and clinical measurements, and biochemical testing. Data on their nutritional intake and dietary habits were collected as well. A randomly selected subgroup of 735 individuals was further tested for serum fatty acids ratios. Our goal was to 1) determine the effect of the rs1801282 polymorphism in the PPARγ gene on the anthropometric, clinical and biochemical parameters, 2) determine the effect of the interaction between the rs1801282 polymorphism in the PPARγ gene and obesity or overweightness on the observed parameters. The frequency of Ala allele in our sample was 15%. Ala allele was associated with lower fasting c-peptide (p=0,006) and fasting insulin levels (p=0,035). In obese Ala boy carriers higher levels of phospholipid and triacylglycerol...

Polymorfismus rs v genu PPARG ve vztahu ke koncentraci a složení mastných kyselin u českých adolescentů / Polymorphism rs in the PPARG gene in relation to the concentration and composition of fatty acids in Czech adolescents

The prevalence of obesity and type 2 diabetes in the adolescent population has been steadily rising. According to the previous studies, the rs1801282 (Pro12Ala) polymorphism in the PPARG gene is connected to the development of obesity, hypertension, insulin resistance, hyperlipemia, and other markers of type 2 diabetes. Data collection was undertaken as part of the COPAT project (Childhood Obesity Prevalence and Treatment). A sample of 2246 Czech adolescents aged 13-17 was genotyped using RT-PCR. 735 individuals from this sample were subjected to further anthropometric and clinical measurements, and biochemical testing. Data on their nutritional intake and dietary habits were collected as well. Our goal was to 1) determine the effect of the polymorphism on the anthropometric, clinical and biochemical parameters, 2) determine the effect of the genotype-phenotype interaction on the lipid spectra. We measured the frequency of Ala allele as 15%. Ala allele was associated with lower fasting c-peptide (p=0,006) and fasting insulin levels (p=0,035). In obese Ala carriers we detected higher levels of phospholipid and triacylglycerol ω-3 polyunsaturated fatty acid than in lean Ala carriers or obese noncarriers.

Metabolická specifika žen s pozitivní anamnézou gestačního diabetu / Metabolic specifics of women with a positive history of gestational diabetes

Jarošová, Adéla January 2017 (has links)
Gestational diabetes (GDM) is a disorder of glucose metabolism arising for the first time in pregnancy and spontaneously receding after birth. The issue of GDM is very topical since, according to the latest update of diagnostic criteria, up to 17% of pregnant women is threatened by this disorder. The incidence of GDM correlates with the increasing prevalence of overweight/obesity and metabolic syndrome. It is proved that women who have had gestational diabetes have an enormously increased risk of developing type 2 diabetes mellitus (DM2T). The risk accosiated with a gestational diabetes pregnancy stretches beyond the host, and can affect the fetus both directly (e. g. macrosomia development), and epigenetically (increases susceptibility to obesity, DM2T development or cardiovascular disease). Significant influence on the development of GDM (or DM2T) is a body composition that is directly related to lifestyle (nutritional intake and physical activity) and genetic role i salso involved. Early intervention may help delay the risk of developing DM2T and other metabolic complications. In this diploma thesis we monitored metabolic profiles of glucose and lipids and body composition based on anthropometric examination and questionnaires of nutritional income and physical activity. For the complex...
