Project description:Calcific aortic valve disease is the most common form of valvular heart disease in the Western World. Milder degrees of aortic valve calcification is called aortic sclerosis and severe calcification with impaired leaflet motion is called aortic stenosis. We used microarrays to detail the global programme of gene expression underlying cdevelopment of calcified aortic valve disease in humans.

Project description:Reactive gliosis is a complex process that involves profound changes in gene expression. We used microarray to indentify differentially expressed genes and to investigate the molecular mechanisms of reactive gliosis in optic nerve head in response to optic nerve crush injury. C57Bl/6 female mice were 6-8 weeks old at the time of optic nerve crush surgery. The optic nerve in the left eye was crush 1 mm behind the globe for 10 seconds and the right eye served as contralateral control. The animals were allowed to recover for 1 day, 3 day, 1 week, 3 weeks and 3 months before the optic nerve heads were collected. The naive control mice did not receive any surgery in either eye. Due to the small tissue size of the mouse optic nerve head, two optic nerve heads were pooled together for each microarray chip. The left eyes and the right eyes of two mice were combined respectively to form one pair of experiment and control samples. There were five biological replicates (10 mice) for each condition.

Project description:Erythrocytes were infected with Plasmodium chabaudi chabaudi AS strain expressing GFP. After 2 or 3 passages, a suspension of 100,000 infected erythrocytes in 1X-PBS (adjusted volume of 200µl) were injected i.p. in wild-type C57BL/6j mice and Homozygous mutant Ighm tm1Cgn mice (lacking mature B-cells). As a control, wild-type C57BL/6j mice and Homozygous mutant Ighm tm1Cgn mice were injected i.p with PBS. There were 3 mice (biological replicates) for each of the 4 experimental conditions. Parasitemia was monitored by flow cytometry and PCR weekly. 117 days post infection, mice were euthanized in CO2 chamber and femur and tibia bones were collected in 1X-HBSS/2% FBS. The cells were removed from the bones and the erythrocytes lysed by hypotonic lysis. Cells (20 million) were antibody stained and the 100K cells (Live/CD11b+/Ly6G-/F4/80+) were sorted in 1X-HBSS/20% FBS. For each sample. 50,000 viable cells were pelleted and lysed with cold ATAC-Resuspension Buffer (RSB) containing 0.1% NP40, 0.1% Tween-20, and 0.01% Digitonin and incubated in ice for 3 minutes. The lysaste was washed with 1 ml of cold ATAC-RSB containing 0.1% Tween-20 but NO NP40 or digitonin. Nuclei were pelleted at 500 RCF for 10 min at 4 degrees celcius. The supernatant was discarded and the pellet was resuspended in 50 uL of transposition mixture (25 ul 2x TD buffer, 2.5 ul transposase (100nM final), 16.5 ul PBS, 0.5 ul 1% digitonin, 0.5 ul 10% Tween-20, 5 ul H2O). The reaction was incubated for 30 minutes in a thermomixer with 1000 RPM mixing. Zymo DNA Clean and concentrator kit (cat# D4014) was used as a cleanup step. The DNA was amplified at 98 degrees C for 30 seconds, then 13 cycles of: 98 degrees C for 10 seconds, 63 degrees C for 30 seconds, 72 degrees C for 1 minute.The library was evaluated in an Agilent TapeStation system and the DNA concentration evaluated by Qubit. Sequencing was performed on Illumina Nextseq 500 with Buffer cartridge v2: Ref: 15057941, High output reagent cartridge v2: Ref: 15057934, NextSeq accessory Box v2: Ref: 15058251, and High output Flow Cell cartridge v2.5: Ref: 20022408

Project description:Patients received standardized coartem therapy. Briefly, each pill contains 20 mg of artemether and 120 mg of lumefantrine. The dose and total coarse of tablets is based on the patients body weight. Blood was drawn from patients prior to anti-malarial treatment (day 0) and after treatment (day42 for children and day 28 for adults). Peripheral Blood Mononuclear Cells were isolated from all patients. Briefly, for PBMC isolation, whole blood from was diluted 1:2 in sterile PBS and overlaid on Ficoll Paque-PLUS in 50 mL conical tubes and centrifuged 800xg for 15 minutes at 25°C with no brake. Resulting buffy coats were collected and washed twice in RPMI 1640 medium, and then cells were treated with Red Blood Cell Lysis Buffer for 3 minutes at room temperature. Cells were washed in RPMI and counted on a hemacytometer. Monocytes were purified from PBMC using a miltenyi Pan Monocyte Isolation negative selection kit according to the manufacturer's instructions. For each sample. 50,000 viable cells were pelleted and lysed with cold ATAC-Resuspension Buffer (RSB) containing 0.1% NP40, 0.1% Tween-20, and 0.01% Digitonin and incubated in ice for 3 minutes.

Project description:<p><strong>BACKGROUND:</strong> Calcific aortic valve stenosis (CAVS) is the most prevalent valvular heart disease in developed countries with significant morbidity and mortality. Given the poor understanding of the pathophysiological processes leading to CAVS, we utilized a joint non-targeted metabolomics and targeted lipidomics approach to better characterize the metabolic perturbations involved in its development and progression.</p><p><strong>METHODS:</strong> We collected human aortic valve tissue from 106 patients undergoing aortic valve replacement surgery. Our cohort represented aortic valvular hemodynamics from mild to severe aortic stenosis with varying degrees of valvular calcification.</p><p><strong>RESULTS:</strong> Seventy-two significantly differential (p<0.01) metabolites across different stages of CAVS severity were filtered and identified from the tissue metabolome. Each stage of valvular stenosis was characterized by a distinct metabolic signature. The top three perturbed metabolic pathways in the setting of CAVS involved glycerophospholipid metabolism, linoleic acid metabolism and primary bile acid biosynthesis. The lysophosphatidic acid species (LysoPA) exhibited significant (p<0.05) association with CAVS severity and were also found to select patients with accelerated rate of CAVS progression. Two LysoPA species namely, 18:2 LysoPA and 20:4 LysoPA, exhibited potential to serve as biomarkers of CAVS severity.</p><p><strong>CONCLUSIONS:</strong> The present study reports the largest and most comprehensive metabolomics analysis of human aortic valve stenosis that highlights the dysregulated LysoPA pathway involved in the pathogenesis of CAVS.</p>

Project description:Guided by gut sensory cues, humans and animals prefer nutritive sugars over non-caloric sweeteners. But how the gut differentiates such stimuli to rapidly guide preferences remains unknown. In the intestine, innervated enteroendocrine cells synapse with the vagus nerve to convey luminal sugar stimuli to the brain within seconds. Here, we sequenced individual vagal nodose neuron cells from the left and right nodose to assess their relative contribution to sugar signaling from the gut. The neurons lack expression of sugar receptors and transporters, but do express receptors for neurotransmitters and neuropeptides secreted by intestinal sensory epithelial cells.

Project description:(Erectile dysfunction) ED during the radical prostatectomy (RP) treatment is caused by surgical injury of the cavernous nerve which is the final neuronal pathways of penile erection. We performed microarray experiment focused on theto understanding the gene signature alteration in the corporal cavernous tissue of the CNI-induced ED rat model. A total of 6 adult male Sprague-Dawley rats were randomly divided into two groups, sham operation (n=3) and bilateral CN resection (n=3) group. At 12 weeks after CN resection, penile tissue was harvested and microarray experiment was performed.
