Study of genetic and infectious risk factors in the pathogenesis of obesity in Czech adolescents.
Elblová, Lenka
4 Abstract The prevalence of obesity and its related cardiometabolic complications in children remains high across the world. Obesity is a multifactorial disease caused by interaction between genes and environmental factors. Genome-wide association studies have discovered several single nucleotide polymorphisms associated with obesity. A causal role of infection in the pathogenesis of obesity has also been considered, particularly the role of adenovirus 36 (Adv36). The aim of the Ph.D. thesis was to investigate the associations of obesity susceptibility loci (TMEM18, SH2B1, KCTD15, PCSK1, BDNF, SEC16B, MC4R, FTO) and Adv36 infection with obesity-related characteristics and complications in the Czech adolescent population. The results are described in eight publications, of which six are original papers and two are reviews. Studies were performed on a cohort of Czech adolescents recruited either from the general population (1,533 individuals from the epidemiological study) and from in-patient or outpatient weight management clinics (562 overweight/obese individuals underwent an intervention). The results demonstrated an association of TMEM18, SEC16B and FTO gene variants with obesity. Some variants of the genes involved in hypothalamic regulation of energy homeostasis − MC4R, BDNF, PCSK1 − were related to...

Pharmacogenetics of statins and metabolic syndrome
Kučera, Miroslav ; Šeda, Ondřej (advisor) ; Schierová, Michaela (referee)
Metabolic syndrome is one of the most prevalent conditions in our population. Among components of the syndrome is a major risk factor of cardiovascular diseases - a change in blood lipid profile presented by alterations in cholesterol and triacylglycerol levels. Statins are currently the drug of choice for therapy of dyslipidemia. This group of drugs is characterized by inhibition of cholesterol synthesis in liver. Pharmacogenetics is a progressive field studying interactions between drugs and genetic background of a patient. There has been described a large amount of genetic variants affecting pharmacokinetic and pharmacodynamic aspects of statin effects. These variants were shown to be important for course of treatment and development of side effects such as statin myopathy. First, this work characterizes pharmacogenetics, metabolic syndrome and statins. Second, it provides a comprehensive summary of genetic polymorphisms underlying important pharmacogenetic interactions with statins.
