Lucie Vybulková The study of transforming growth factor receptor during atherogenesis in mouse model of atherosclerosis Diploma thesis Charles University in Prague, Fakulty of Pharmacy in Hradec Králové Pharmacy Background: The aim of this diploma thesis was the establishment of methodology for detection of TGF-βRI, subtype ALK-5, and studying its expression in the aortic root in apoE/LDLr- deficient mice. Methods: Using female mice C57BL/6J strain with a double deficit of apolipoprotein E and LDL-receptor was performed biochemical analysis of blood specimens, histologic staining with oil red for detection of lipids in tissues and immunohistochemical analysis of segments of tissue from the aorta and the top half of the heart. To detect expression of ALK-5 was used EnVision method with DAB visualization. Results: Using biochemical analysis, we confirmed increased levels of cholesterol in mice fed cholesterol diet as compared with mice on standard diet. At histologic staining with oil red we detected increased formation of atherosclerotic lesions in mice with cholesterol diet. Immunohistochemical analysis of expression of ALK-5 we demonstrated high expression of ALK-5 in the tunica media and in atherosclerotic plaques with no significant difference in the two groups of mice. Conclusion: The results...

Immunohistochemical Analysis of Expression of Phosphorylated form Smad2 after Administration of Atorvastatin in Experimental Atherogenesis
Vybulková, Lucie ; Nachtigal, Petr (advisor) ; Doleželová, Eva (referee)
Charles University in Prague, Faculty of Pharmacy in Hradec Králové Department of Biological and Medical Sciences Candidate Mgr.Lucie Vybulková Consultant Doc.PharmDr.Petr Nachtigal, PhD Title of Thesis Immunohistochemical analysis of expression of phosphorylated form Smad2 after administration of atorvastatin in experimental atherogenesis Background: The aim of this thesis was to describe the effects of atorvastatin treatment on the expression of phosphorylated form of Smad2 in atherosclerotic plaques in ApoE/LDLr-deficient mice by immunohistochemical methods. Furthermore, the influence of atorvastatin on lipid spectrum and size of atherosclerotic plaques was observed. Methods: In our experiment there were used C57BL/6J female mice with double deficit of apolipoprotein E and LDL receptor. There was performed the biochemical analysis of blood samples, histological staining with oil red for detection of tissue lipids, quantitative analysis of size of lesions and immunohistochemical analysis of samples containing semilunar valves and aorta for the detection of expression of Smad2. It was done using the method Avidin-Biotin and detection with DAB. Results: Using biochemical analysis we confirmed increased levels of total cholesterol and VLDL after the administration of atorvastatin. Smaller size of...
