RNA Sequencing of livers from ApoE-/- mice treated with HIF1a inhibitor PX-478 or Saline

Project description:Purpose: HIF1a inhibitor PX-478 prevents hypercholesterolemia in ApoE-/- mice fed Western diet for 3 months. The goal of this study was to determine the mechanisms in the liver through which PX-478 regulates cholesterol. Methods: 4-week old ApoE-/- mice were fed a Western diet and injected intraperitoneally, bi-weekly with either PX-478 (40 mg/kg) or Saline for 3 months. The livers of 3 PX-478-treated mice and 4 Saline-treated mice were used for this RNA-seq study. Results: We identified 800+ differentially expressed genes in the PX-478-treated ApoE-/- mice livers relative to the saline-treated control livers. A subset of these genes were found to play important roles in cholesterol regulation and were further validated by qPCR analysis. Conclusions: Our study details potential hepatic cholesterol regulating mechanisms for HIF1a inhibitor PX-478. These results, coupled with our findings on the effect of PX-478 on two different mouse models of atherosclerosis, demonstrate that PX-478 is a potential anti-atherogenic and anti-hypercholesterolemic drug.

Transcription profiling of mouse suprarenal aorta from ApoE knock-outs treated with angiotensin II or saline to study developing abdominal aortic aneurysm (AAA)

Project description:Transcriptional profiling of suprarenal aorta from ApoE-/- mice (12-14 weeks old, C57BL/6J background) treated by subcutaneous pump with angiotensin II or saline for 7d, 14d and 28d. Includes Ang II-treated samples at 7d found to have dissected aneurysms. Goal was to examine gene expression in developing AAA in this model over time. Experiment Overall Design: Two condition experiment, one suprarenal aorta per array. Saline vs. angiotensin II at 3 time points, with inclusion of 3 Ang II-treated dissected. Total 35 arrays: 6 saline 7d, 6 saline 14d, 5 saline 28d, 4 Ang II 7d, 5 Ang II 14d, 6 Ang II 28d, 3 Ang II-dissected 7d.

Angiotensin II induced aneurysms in male ApoE mice

Project description:In this study we used microarrays to examine relative genes expression within the aorta of ApoE-/- infused with angiotensin II in relation to aneurysm formation. Infusion of angiotensin II induces aortic dilatation particularly of the suprarenal aorta in ApoE-/- mice. Based on studies carried out in our and other laboratories the response to angiotensin II is variable, with some mice developing large aneurysms but other animals appearing resistant to aneurysm formation with aortic diameters similar to that of saline controls. We compared RNA expression from whole aortas of 17 week old male ApoE-/- mice exposed to angiotensin II (1.44 Âµg/kg/min) for 4 weeks where there was clear evidence of aortic aneurysm formation (n=5) with that of mice failing to develop aneurysms (n=7) and those exposed to saline infusion (n=6). AAA was defined as diameter of suprarenal aorta greated than 1.5mm measured on photographs of aortas at necroscopy. Keywords: Disease state analysis 18 samples analysed, AAA (n=5), no AAA (n=7), saline (n=6). AAA - abdominal aortic aneurysm

Metaproteomic datasets of wheat rhizosphere from saline and non-saline soils

Project description:We present metaproteome data from wheat rhizosphere from saline and non-saline soil. For collection and acquisition of metaproteome from wheat rhizosphere under saline and normal conditions, a survey was conducted in regions of Haryana, India. Samples from 65 days old plants (wheat var HD2967) were collected and pooled and based on EC,saline (NBAIM B; EC 6mS cm-1; pH 9.0; Bhaupur 2, Haryana, INDIA; 29°19'8"N;76°48'53"E) and normal soil samples (NBAIM C; EC 200 uS cm-1; pH 7.2; Near Nainform, Haryana, INDIA; 29°19'8"N;76°48'53"E) were selected for isolation of proteome with the standardized protocol at our laboratory followed by metaproteome analysis with the standardized pipepline. In total 1538 and 891 proteins were obtained from wheat rhizosphere from saline and non-saline respectively with the given parameters and software. Among 1410 proteins unique for saline soil, proteins responsible for glycine, serine and threonine metabolism and arginine and proline biosynthesis were found in saline and absent in non-saline. The present study extends knowledge about the physiology and adaptations of the wheat rhizosphere associated microbiota under saline soil.
