Pregnancy proteins - molecular biological and biochemical analysis
Muravská, Alexandra ; Kalousová, Marta (advisor) ; Černá, Marie (referee) ; Průša, Richard (referee)
The aim of this thesis was to establish methods for selected PAPP-A (Pregnancy- Associated Plasma Protein A) gene polymorphisms analysis and to study genetic background of PAPP-A and biochemical background of PAPP-A and PlGF (Placental Growth Factor) in relation to risk pregnancy. Secondly, the aim was to establish method for two-dimensional (2D) electrophoresis of amniotic fluid. Methods for analysis of ten PAPP-A gene polymorphisms were established. These polymorphisms, PAPP-A and PlGF levels were studied in together 165 women in third trimester pregnancies complicated with threatening preterm labor (n=98), preeclampsia (n=35), IUGR (Intrauterine Growth Restriction) (n=34) and ICP (Intrahepatic Cholestasis of Pregnancy) (n=15). 114 healthy pregnant women served as controls. The method for 2D electrophoresis of amniotic fluid was established. Preeclamptic patients had significantly higher frequency of TT genotype of Cys327Cys (C/T) PAPP-A gene polymorphism compared to controls. Patients with ICP had increased serum levels of PAPP-A compared to controls, in patients with threatening preterm labor PAPP-A levels were rather decreased. PlGF levels did not differ from control group in patients with ICP and threatening preterm labor. Positive correlation was found between PAPP-A and PlGF in group of...

Novel biomarkers in patients with renal disease
Zakiyanov, Oskar ; Kalousová, Marta (advisor) ; Teplan, Vladimír (referee) ; Průša, Richard (referee)
Chronic kidney disease (CKD) and acute kidney injury (AKI) are major public health problems. It is important to be able to identify those at high risk of adverse outcome, CKD progression and associated cardiovascular disease. The aim of the thesis was to study novel promising biomarkers, their relationship to kidney function, chronic inflammation and/or cardiovascular risk - placental growth factor (PlGF), pregnancy associated plasma protein A (PAPP-A), matrix metalloproteinase 2 (MMP-2), matrix metalloproteinase 9 (MMP-9), soluble receptor for advanced glycation end products (sRAGE), calcium binding protein S100A12 or extracellular newly identified RAGE binding protein (EN-RAGE), and high mobility group box protein-1 (HMGB-1) in patients with renal diseases including CKD, haemodialysis (HD), AKI patients, and healthy controls for comparison. First study revealed that PlGF is elevated in patients with decreased renal function. Second study demonstrated the association of MMP-2 and PAPP-A with proteinuria in patients with CKD. Moreover, serum MMP-2, MMP-9 and PAPP-A levels significantly differed in patients with various nephropathies. EN-RAGE levels are not elevated in patients with CKD, but are related to inflammatory status. PAPP-A, EN-RAGE and HMGB-1 levels are significantly elevated, but sRAGE and PlGF...
