Functional genomic and pharmacogenomic analysis of metabolic syndrome aspects
Krupková, Michaela ; Šeda, Ondřej (advisor) ; Haluzík, Martin (referee) ; Polák, Jan (referee)
Metabolic syndrome is a prevalent disease characterized by concurrent manifestation of insulin resistance, obesity, dyslipidemia, hypertension and other hemodynamic and metabolic disorders. It has multifactorial type of inheritance and its resultant phenotype is determined by both environmental and genetic factors as well as their interactions. That is the main reason why comprehensive analysis of the genetic component of this syndrome is complicated in human population. Genetically designed experimental animal models are significant tools for analysis of genetic architecture of human complex conditions including the metabolic syndrome. The aim of this Thesis is utilization of functional and comparative genomic tools to uncover pathogenesis of metabolic syndrome aspects and their genetic determinants. We also studied pharmacogenetic interactions of these genetic determinants with drugs affecting particular components of the metabolic syndrome. Establishing and utilizing several genetically designed congenic rat strains, we undertook four different research projects focusing on pharmacogenetic interaction of all-trans retinoic acid and ondansetron with differential segment of rat chromosome 8, pharmacogenetic interaction of differential segment of rat chromosome 4 and dexamethasone, determining Plzf...

Vztah SNP v genu pro leptin a parametrů vnitřního prostředí býků Českého strakatého skotu
Lysáková, Eva
There is a lot of factors which has impact on quality of bovine meat. The aim of this thesis was to examine correlations between chosen SNPs in leptin gene and specific hormones and metabolites, which have influence on the meat quality and also complete health condition of beef. There were 99 bulls of Czech Fleckvieh cattle used for this study. The examined parameters were insulin, glucose, cholesterol, triacylglycerol, non-esterified fatty acids and betahydroxybutiric acid. There was shown no statistically signifiant correlation between leptin gene polymorfisms and observed parameters. Only proved correlation was between leptin and cholesterol and glucose. There is lot of other factors involved in changes of amount of these substances though.

Studium SNP genu DGAT1 jako kandidátního genu pro kvalitu vepřového masa
Tomášková, Marie
This work was focused on the study of variability DGAT1 gene in the pig population Czech Large White breed. Subsequently, association analysis was performed of the gene and the different production indicators of quality of pork meat. Examined polymorphism was found at position 103 of intron 2 of chromosome 4. DGAT1 gene has a major role in the synthesis tryacylglycerols and may affect the storage of fat in the body. Relative genotype frequencies were: AA = 0.4222; AG = 0.4889; GG = 0.0889. The values of the relative frequencies of alleles were as follows: A = 0.6666 and G = 0.3334. The association analysis didn't show any statistically significant differences.

Influence of increased aplication of the file polyunsaturated fatty acids on alteration of level cholesterol of individuum.
FLANDERKOVÁ, Michaela
I have engaged in the influence of increased aplication of the file polyunsaturated fatty acids on alteration of level cholesterol of individuum in my bachelory work. At first I had studied theoretical knowledge focused the theme of polyunsatureted fatty acid and cholesterol. I had devoted to this knowledge in theoretical part of my bachelory work. After I had contacted some people. I had known that they have increased cholesterol level. This people I had acquainted with themes of my bachelory work and development of research. The acquainted people have accepted part of research. Initial measuring taked place after. The measuring determined the level of total cholesterol, LDL cholesterol, HDL cholesterol, triacylglycerol. The three month interventionist program taked place after, from march 2011 to december 2012. The Participant of research had consumed of food supplement, which contented fish oil. Fish oil is rich in content of polyunsaturated fatty acid omega 3 (EPA and DHA). Output measuring taked place after three month. On the basis of measuring got results. I worked with results in the practical part of my bachelory work. I have compared results of initial and output measuring.

Analysis of lipids mobilized by adipokinetic hormones in the firebug Pyrrhocoris apterur (Heteroptera: Pyrrhocoridae)
BÁRTŮ, Iva
An effect of two adipokinetic hormones (Pyrap-AKH and Peram-CAH-II) on distribution of diacylglycerol (DG) molecular species and their fatty acid (FA) constituents were investigated by liquid chromatography (HPLC) - electrospray ionization mass spectrometry (ESI-MS) in haemolymph of the firebug Pyrrhocoris apterus. The results show that DGs with characteristic FAs are preferentially mobilized from fat body (FB) by the action of both AKHs produced by P. apterus. Both the macropterous and brachypterous morphs show very close DG and FA profiles. A separate action of the Pyrap-AKH and the Peram-CAH-II, however, exerts distinct differences in FA distribution at the macropterous morph. It seems that partially C16 and mainly unsaturated C18 FAs play a dominant role in the AKH action with an exclusive position of linoleic acid (18:2) which represents 50 - 60% of the total DG mobilization. The metabolically active C16 and C18 FAs are preferentially absorbed from the linden seeds and accumulated in the FB.
