Project description:Aortic arch profiling of Apoe-/- mice fed a high fat diet (HFD, Harlan Teklad 88137, 21% fat, 0.15% cholesterol) starting at 8 weeks of age for 8, 16, and 24 weeks. B6 mice fed HFD for 16 weeks starting at 8 weeks of age were used as controls.

Project description:Strain differences influence susceptibility to atherosclerosis. Apolipoprotein E-null mice on a DBA/2J genetic background (DBA-apoE) and C57BL/6 (B6-apoe) are highly susceptible to atherosclerosis in the aortic root area compared with those on a 129S6/SvEvTac background (129-apoE). To explore strain-specific differences affecting the susceptibility to atherosclerosis, we performed microarray analysis of aortic arch and root from wild type mice of each strains.

Project description:The goal of this study is to determine whether A1 adenosine receptor (ADORA1) plays a role in atherosclerosis development and its possible mechanisms. This dataset compares gene expression (aortas) of ADORA1 knockout mice to ADORA1+APOE double-knockout mice. Mice deficient in both ADORA1 and APOE (DKO) demonstrated reduced atherosclerotic lesions in aortic arch (en face), aortic root, and innominate arteries when compared to (APOE-KO) of the same age. Treating APOE-KO with the ADORA1 antagonist DPCPX also achieved concentration-dependent reduction in lesions. The total plasma cholesterol and triglyceride levels were not different between DKO and APOE-KO, however, higher triglyceride was observed in DKO fed a high-fat diet. DKO also were heavier than APOE-KO. Plasma cytokine levels (IL-5, IL-6, and IL-13) were significantly lower in DKO. Proliferating cell nuclear antigen (PCNA) expression was also significantly reduced in the aorta from DKO. Despite smaller lesions in DKO, the composition of the innominate artery lesions and cholesterol loading and effusion [export] from bone-marrow-derived macrophages from DKO were not different from APOE-KO.

Project description:Objective—Overexpression or administration of sclerostin has been reported to have atheroprotective and anti-inflammatory effects in apolipoprotein E knockout (ApoE KO) mice infused with angiotensin II; however, effects of sclerostin inhibition on these processes are not known. This study examined the effects of sclerostin inhibition with a sclerostin antibody on transcriptional changes in the aortic arch, associated morphological changes in aortic atherosclerotic plaques, and circulating markers of inflammation in ApoE KO ovariectomized (OVX) mice fed a high-fat diet. Approach and Results—Sclerostin antibody or vehicle was administered by subcutaneous injection once weekly for 3, 8, or 16 weeks to ApoE KO-OVX and wild-type-OVX mice fed a high-fat diet. As a comparator, alendronate or saline was administered twice weekly for 16 weeks to ApoE KO-OVX mice fed a high-fat diet. Sclerostin antibody had no effect on aortic total or mineralized plaque volume, determined by microcomputed tomography. Sclerostin antibody had no meaningful effects on plaque histopathology or systemic markers of inflammation or endothelial/platelet activation. Transcriptional analysis of the aortic arch revealed significant gene expression and signaling pathway changes in ApoE KO mice compared with wild-type, consistent with the genotype and atheroprogression, that were not affected by sclerostin antibody treatment. Alendronate treatment did not alter plaque volume or histopathology. Conclusions—This study shows that inhibition of sclerostin by sclerostin antibody does not promote atheroprogression or affect systemic markers of inflammation in the high-fat diet ApoE KO-OVX mouse model and does not alter the expression of genes/pathways implicated in atherosclerosis.

Project description:Aortic arch profiling of Apoe-/- mice fed a high fat diet (HFD, Harlan Teklad 88137, 21% fat, 0.15% cholesterol) starting at 8 weeks of age for 8, 16, and 24 weeks. B6 mice fed HFD for 16 weeks starting at 8 weeks of age were used as controls. Apoe-/- mice were fed a high fat diet (HFD, Harlan Teklad 88137, 21% fat, 0.15% cholesterol) starting at 8 weeks of age for 8, 16, and 24 weeks. B6 mice fed HFD for 16 weeks starting at 8 weeks of age were used as controls. At each time point, 9 mice were studied. Mice were euthanized at each time point and whole aorta (from aortic root to renal bifurcation) of each mouse was immediately collected and flash-frozen in liquid N2. Mice were fasted overnight prior to euthanasia. the aortic arches of three mice in the same study group were pooled, resulting in three pools per study group.

Project description:ApoE-/-mice were fed chow or Western diet for 12 weeks and NPRC expression was significantly increased in the aortic tissues of Western diet-fed mice. Systemic NPRC knockout mice were crossed with ApoE-/- mice to generate ApoE-/-NPRC-/- mice, and NPRC deletion resulted in a significant decrease in the size and instability of aortic atherosclerotic lesions in ApoE-/-NPRC-/- versus ApoE-/- mice.

Project description:The experiment was performed by using Apoe-/- mice fed on a high-fat, high-cholesterol diet (Western diet, WD) for either 6 weeks. The samples were collected from aortic arch and root of two different groups of mice: one treated with rHDL (reconstituted HDL nanoparticles), and the other with PS@rHDL (reconstituted HDL nanoparticles incorporating phosphatidylserine).

Project description:The physiological functions other than lipid metabolism of APOE may interfere with the research results of Apoe-knockout mice as atherosclerosis models. The elucidation of the molecular basis of the physiological functions of APOE other than lipid metabolism will help to make rational use of the Apoe-knockout mouse model. Therefore, our aim is to reveal the changes in aortic gene expression profile caused by Apoe-knockout. We used the second generation sequencing to detect the gene mRNA expression level in the aortic tissues of 5 C57BL/6J mice and 4 Apoe knockout mice. This will provide more clues for studying the physiological function of Apoe, and also remind researchers to pay special attention to the possible interference to the results when using Apoe-knockout mice as atherosclerosis models.
