Emerging cardiovascular risk markers in diagnostics and therapy
Tůmová, Eva ; Vrablík, Michal (advisor) ; Freiberger, Tomáš (referee) ; Polák, Jan (referee)
Cardiovascular diseases (CVD) have been one of the leading causes of morbidity and mortality in developed countries with an enormous influence on individual health and significant socioeconomic impact as well. The aim of most physicians in recent decades is to seek the best possible predicative risk factor (RF) (or combination of several RF) which could help to determine the individual risk of developing CVD. This risk stratification can be used to identify the high risk patients and treatment intensification or establishment of early preventive measures. Currently, several RF of atherosclerosis and CVD are commonly used to individualize health care. However, individuals with low levels of these RF suffer of CVD, therefore the effort to find as much as possible specific RF still persists. In recent years, the inflammatory markers, crucial in the atherosclerosis development, raise great expectation In our studies, we focused on investigating the levels of inflammatory parameters in specific groups of patients (obese children and patients with metabolic syndrome) and observed the effect of weight loss following lifestyle changes. Our main concern was lipoprotein-associated phospholipase A2 (Lp-PLA2), oxidized LDL particles (ox-LDL) and myeloperoxidase (MPO). The results demonstrated significantly...
Variability in LPA gene transcription regulatory sequences

Charles University in Prague, The First Faculty of Medicine Thesis: Variability in LPA gene transcription regulatory sequences Name: Mgr. Kateřina Zídková Thesis Adviser: Prof. Richard Češka, M.D., Ph.D. Consulting Thesis Adviser: Assoc. Prof. Milada Kohoutová, M.D., Ph.D. Summury of Doctorate thesis Increased Lp(a) concentration is an independent risk factor for premature atherosclerosis. The Lp(a) concentration is almost entirely genetically determined with an exclusive linkage to a unique locus, the gene for apo(a), so called LPA locus. Nevertheless Lp(a) concentrations varies widely between individuals in all populations studied so far. There is a LPA gene size heterogeneity (KLPAIV type 2 repetition) accounting for 40-60% of the variance. Some of the variance could be additionally related to polymorphic sites either in the coding sequence or in transcription regulatory regions of LPA gene. We had scanned the LPA gene transcription regulatory regions (promoter, DHII, and DHIII enhancers) for variabilty. None of them was revealed to be extremely polymorphic. However significant linkage disequilibrium was detected even between polymorphic sites from far regulatory sequences. We have investigated if certain compound genotypes of apo(a) gene regulatory sequences could be associated with a narrow range of...
