MicroRNA transciptional profiling in murine abdominal aortic aneurysm (AAA), porcine pancreatic elastase (PPE) model - Day 7

Project description:We sought to identify differentially regulated microRNAs in infrarenal mouse aortic tissue after AAA-induction with PPE, compared with sham-operated mice. This treatment leads to rapid development of infrarenal aortic aneurysms with significant diameter differences observed by Day 7. We found 41 miRNAs were up-regulated with aneurysm and 37 down-regulated at p<0.05, which were also altered by >1.5-fold. Utilizing the PPE infusion model, we induced AAA in Male 10-week-old C57/Bl6 mice, 7 days after AAA-induction with PPE. One array per mouse, 5 mice per group, two groups (PPE and sham).

Murine Abdominal Aortic Aneurysm, PPE Model - In Vivo Modulation of miRNA-24 (Day 7)

Project description:Transcriptional profiling of infrarenal aortic tissue from Male 10-week-old C57BL/6J mice after AAA-induction with porcine pancreatic elastase, compared with sham-operated saline-injected mice. One day after AAA-induction, the mice were injected intraperitoneally with either lentiviral packaged miR-24 antagomir (anti-miR-24) or miR-24 mimic (pre-miR-24), or a scrambled microRNA control (scr-miR). Aortic samples were obtained 7 days after operation. The goal was to examine gene expression in developing AAA in this model, and to compare the effects of scr-miR, anti-miR-24 and pre-miR-24. Four condition experiment, one infrarenal aorta per array. Sham vs. scr-miR-PPE vs. anti-miR-24-PPE vs. pre-miR-24-PPE, all harvested at Day 7 post-operatively. After QC, the final analysis group (uploaded here) consisted of 18 arrays: Sham-Saline-treated (4 arrays), scr-miR-PPE-treated (5 arrays); pre-miR-24-PPE-treated (3 arrays); and anti-miR-24-PPE-treated (6 arrays).

Is Increased Sinusoidal Flow in the Liver Remnant the primary Stimulus to Regeneration after partial Hepatectomy

Project description:The impact of portal arterialization on the liver parenchyma was studied in a series of six pigs with aortoportal shunting of liver segments II, III and IV (and 6 sham animals). Gene expression in the arterialized segments was compared to expression in sham animals. Primary endpoints were gene expression profiles in the hyperperfused segments at sampling time points 1, 5, 10, 30, 60, 90 minutes and 2, 3, 4 and 6 hours after shunt opening. Keywords: time course, treatment comparison Six pigs were treated with aortoportal shunting of segments II, III and IV and six animals were subject to sham surgery. Expression profiling was conducted by hybridizing each sample against a common reference, consisting of liver RNA from an unrelated animal..

Abdominal Aortic Aneurysm in C57BL/6J Mice - Male and Female PPE vs. Sham Day 7

Project description:Transcriptional profiling of infrarenal aorta from male and female mice (10-weeks old, C57BL/6J), treated with either porcine pancreatic elastase (PPE) local infusion or sham operation (saline infusion). Samples harvested 7 days after treatment. Goal was to examine gene expression in AAA in this model in both genders. Surgical protocol is as described in PMCID: PMC3148686/PMID: 19629030.

Testosterone deficiency altered mortality and the expression profile of protease inhibitors in an elastase-induced mouse model of emphysema

Project description:To evaluate the effect of testosterone on the pathophysiology of COPD, we created porcine pancreas elastase (PPE)-induced emphysema mouse model in sham or orchiectomized (ORX) mice [sham/PBS, sham/PPE, ORX/PBS, and ORX/PPE]. We performed microarray analysis to compare the gene expression levels in the lungs of each mice group. The results demonstrated that the levels of genes encoding protease inhibitor activity in ORX/PPE mice were lower than those in sham/PPE mice.

Gene expression profile of STIM1 deficiency for cardiac remodeling in response to pressure overload by transverse aortic constriction (TAC)

Project description:STIM1 is a Ca2+ sensor of intracellular Ca2+ stores and essentially activates the Ca2+ entry channels of the plasma membrane. STIM1 is predicted to activate transient receptor potential canonical (TRPC) channels and Orai channels, and has a critical role in promoting the development of cardiac hypertrophy. Gene array experiments were performed to analyze the effects of STIM1 deficiency using total RNA from the left ventricles of WT sham, WT TAC, STIM1KO sham and STIM1KO TAC 4 weeks after the operation.

Identification and characteristics of microRNAs in rat abdominal aortic aneurysms

Project description:Abdominal aortic aneurysm (AAA) is a lethal disease, occurring mostly in men more than 65 years of age. Until recently, the pathogenesis of AAA remains poorly understood. MicroRNAs (miRNAs) are a novel class of endogenous small noncoding RNAs that play important roles in diverse biological and pathological processes and was more recently investigated in cardiovascular physiology and pathology. In this study, we employed microarray to detect and compare miRNA expressions of AAAs in rats. Four miRNAs were validated using real time RT-PCR. Functional annotations of putative targets of deregulated miRNAs via bioinformatics approaches revealed that predicted targets were highly enriched and involved in several signaling pathways important for AAA formation. Our results indicate that miRNAs are extensively involved in rat AAA formation and provide a global view of AAA miRNA profiles, which is expected to provide new clues to develop targeted therapies against this calamitous disease. Sprague-Dawley rat AAA model was established by calcium chloride and collagenase co-incubation method. After 28 days, three rats with confirmed AAAs and three normal rats form control(sham operation) group were euthanized and the aortas specimens were used for this experiment.
