Project description:Microarray gene expression profiling of aorta genes of APOE-deficient mice receiving atherosclerosis treatment with the ACE inhibitor captopril. Hypercholesterolemic APOE-deficient mice were used as a standard model of atherosclerosis to study gene expression changes during atherosclerosis treatment with the ACE inhibitor captopril. Microarray analysis was performed of whole aortas isolated from captopril-treated APOE-deficient mice relative to untreated APOE-deficient mice with overt atherosclerosis, and nontransgenic control mice. Microarray gene expression profiling revealed that captopril-mediated atherosclerosis prevention involved inhibition of aorta-infiltrating immune cells such as pro-atherogenic T lymphocytes and macrophages. Experiment Overall Design: Microarray gene expression profiling was performed of whole aortas isolated from APOE-deficient mice with atherosclerosis relative to captopril-treated APOE-deficient mice, and nontransgenic control mice. Three study groups were analyzed, i.e. 8-months-old untreated APOE-deficient mice with overt atherosclerosis, age-matched APOE-deficient mice treated for 7 months with the angiotensin-converting enzyme (ACE) inhibitor, captopril (20 mg/kg in drinking water), and nontransgenic control C57BL/6J mice. Two biological replicates were made of each group, and total RNA of three aortas was pooled for one gene chip.

Project description:Hypercholesterolemic APOE-deficient mice are a widely used experimental model of atherosclerosis and increased generation of reactive oxygen species (ROS) is a prominent feature of atherosclerosis development. To study the impact of ROS on atherogenesis, we treated APOE-deficient mice for 7 months with the antioxidant vitamin E (2000 IU/kg diet) and performed whole genome microarray gene expression profiling of aortic genes. Microarray gene expression profiling was performed of whole aortas isolated from vitamin E-treated APOE-deficient relative to untreated APOE-deficient mice with overt atherosclerosis, and nontransgenic B6 control mice. Microarray gene expression profiling revealed that vitamin E treatment prevented atherosclerosis-related gene expression changes of the aortic intima and media. Microarray gene expression profiling was performed of whole aortas isolated from APOE-deficient mice with atherosclerosis relative to vitamin E-treated APOE-deficient mice, and nontransgenic B6 control mice. Three study groups were analyzed, i.e. 8 months-old untreated APOE-deficient mice with overt atherosclerosis, age-matched APOE-deficient mice treated for 7 months with the antioxidant vitamin E (2000 IU/kd diet), and nontransgenic B6 control (C57BL/6J) mice. Two biological replicates were made of each group, and total RNA of three aortas was pooled for one gene chip. The study complements microarray study GSE19286.

Project description:Chronic kidney disease (CKD) can induce AoSMCs premature senescence and phenotypic switching, which ultimately promotes AS progression and plaque vulnerability. However, the underlying mechanisms are still unknown. To identify the underlying mechanisms of AoSMCs senescence and phenotype switching in CKD. We performed integrated microarray analysis of AoSMCs from normal-diet fed ApoE-/- (ND) mice, high fat-fed ApoE-/- (AS) mice and CKD ApoE-/- (accelerated atherosclerosis mouse model, AAS) mice.

Project description:Enhanced prenatal fatty streak formation in human fetuses has been associated with maternal hypercholesterolemia. However, the possible roles of maternal genetic background and in utero environment on development of atherosclerosis in adult life have not been unraveled. We generated genetically identical heterozygous apoE-deficient mice offspring with a different maternal background to study the intrauterine effect of maternal genotype and associated hypercholesterolemia on the developing vascular system. As read out for increased atherosclerosis development in adult life, a constrictive collar was placed around the carotid artery to induce lesion formation. A significant increase in endothelial cell activation and damage was detected in the carotid arteries of heterozygous apoE-deficient fetuses with apoE-deficient mothers compared with offspring from wild type mothers, but no fatty streak formation was observed. Postnatally, all carotid arteries revealed normal morphology. In adult offspring with maternal apoE-deficiency, the constrictive collar resulted in severe lesion (9/10) development compared with no to only minor lesions (2/10) in offspring of wild type mothers. Microarray analysis showed no effect of maternal apoE-deficiency on gene expression in adult offspring. We conclude that maternal apoE-deficiency not only affects fetal arteries, but also increases the susceptibility for development of collar-induced atherosclerosis in adult life. Experiment Overall Design: Crossing of hypercholesterolemic female with normocholesterolemic male and vice versa, determination of susceptabilioty to atherosclerosis in offspring

Project description:Chronic apical periodontitis, typified by inflammatory granulation tissue formation and alveolar bone destruction, is the immune response around the apical root caused by long-term infection and pathogenic stimulation in the root canal. Through the recruitment and infiltration of immune cells and inflammatory mediators, wound healing begins accompanied by the starting of infection. Hence, a comprehensive understanding of biological processes and disease development from the cellular microenvironment in inflammatory periapical areas has important implications.

Project description:Atherosclerosis and pressure overload are major risk factors for the development of heart failure in patients. Cardiac hypertrophy often precedes the development of heart failure. However, underlying mechanisms are incompletely understood. To investigate pathomechanisms underlying the transition from cardiac hypertrophy to heart failure we used experimental models of atherosclerosis- and pressure overload-induced cardiac hypertrophy and failure, i.e. apolipoprotein E (apoE)-deficient mice, which develop heart failure at an age of 18 months, and non-transgenic C57BL/6J (B6) mice with heart failure triggered by 6 months of pressure overload induced by abdominal aortic constriction (AAC). The development of heart failure was monitored by echocardiography, invasive hemodynamics and histology. The microarray gene expression study of cardiac genes was performed with heart tissue from failing hearts relative to hypertrophic and healthy heart tissue, respectively. The microarray study revealed that the onset of heart failure was accompanied by a strong up-regulation of cardiac lipid metabolism genes involved in fat synthesis, storage and oxidation. Microarray gene expression profiling was performed with heart tissue isolated from (i) 18 month-old apoE-deficient mice relative to age-matched non-transgenic C57BL/6J (B6) mice, (ii) 6 month-old apoE-deficient mice with 2 months of chronic pressure overload induced by abdominal aortic constriction (AAC) relative to sham-operated apoE-deficient mice and nontransgenic B6 mice, (iii) 10 month-old B6 mice with 6 months of AAC relative to sham-operated B6 mice, and (iv) 5 month-old B6 mice with 1 month of AAC relative to age-matched B6 mice.

Project description:Dendritic cells (DCs) are essential for priming of immune responses. Although immune mechanisms are known to control the pathogenesis of atherosclerosis, the role of DCs remains elusive. Here we show that Ccl17 expressing mature, myeloid DCs accumulate within atherosclerotic lesions. Deletion of Ccl17 in apolipoprotein E-deficient (Apoe-/-) mice reduces the development and progression of atherosclerosis in several disease models. While Ccl17 expression by DCs dampened antigen-specific T cell proliferation, it is required for efficient polarization of T helper type 1 (Th1) and Th17 as reflected by a preponderance of Th2 cytokines in Ccl17-/- Apoe-/- mice. In line with these findings, only transfer of T cells from Apoe-/-, but not from Ccl17-/- Apoe-/- precipitated atherosclerosis in T cell depleted Apoe-/- recipients. These findings identify Ccl17+ DCs as central immune regulators in atherosclerosis and Ccl17 as a potential target in the treatment of this disease. There are three samples analyzed with no replicates included. There is one control sample included.

There were two samples analyzed with no replicates included. The two samples should be compared with each other.
