Project description:Urine was obtained from healthy kidney donors, from transplanted kidneys intrasurgery, at postoperative day 1 and at later timepoints. Exosomes were isolated and measured using nLC-MS/MS. For details, see the accompanying manuscript.
Project description:Size fractionated small RNA from total RNA extracts of Cicer arietinum leaves and from Nicotiana benthamiana infected by Cymbidium ringspot virus were mixed in a ratio of 1000 to 1 in amount, respectively. The RNA was ligated to adapters, purified again and reverse transcribed. After PCR amplification the sample was subjected to Illumina high throughput pyrosequencing. The kit used is TrueSeq Small RNA kit Please see www.illumina.com for details of the sequencing technology.
Project description:These is a collection of chromatin proteomics experiments that make up the 80 "in-house" biological conditions covered by ProteomeHD (see publication for more details). All experiments use SILAC, resulting in 80 SILAC ratios comparing the impact of various drugs (estradiol, TSA, hydroxytamoxifen, etc.), growth factors (TNFalpha) or other treatments (ionizing radiation) on chromatin composition. For a more detailed description see the Supplementary Table S2 of the publication, which can also be downloaded from here.
Project description:<p>This is a multi-centre, case-controlled study to develop a dataset containing 1000 MS cases and 1000 matched controls and to associate DNA sequence (allelic) variations with MS phenotypes.</p> <p>Study subjects were enrolled through a prospective effort initiated in 2003. Three MS clinical centres were involved in subject recruitment and biological specimen collection using identical inclusion/exclusion criteria, two in Europe (Vrije Universiteit Medical Center, Amsterdam; and University Hospital Basel) and one in the US (University of California San Francisco). This study recruited subjects of northern-European ancestry with a diagnosis of MS (<a href="http://www.ncbi.nlm.nih.gov/pubmed/11456302" target="_blank">McDonald et al., 2001</a>), with dissemination in time and space. Patients with Clinically Isolated Syndromes (CIS) were also included if they fulfilled 3 of the 4 Barkhof criteria for dissemination in space as per application of the McDonald criteria (<a href="http://www.ncbi.nlm.nih.gov/pubmed/11456302" target="_blank">McDonald et al., 2001</a>). While recruitment predominantly included subjects with a relapsing onset of MS, individuals with all clinical subtypes of the disease participated, including clinically isolated syndrome (CIS), relapsing remitting MS (RRMS), secondary progressive MS (SPMS), primary progressive MS (PPMS), and progressive relapsing MS (PRMS).</p> <p>The control group consisted of unrelated individuals, primarily spouses/partners, friends, and other volunteers.

Project description:MS/MS spectra were collected, 4 months later, from hands and phones of 10 individuals who participated to the first sample collection.

Project description:Sixteen volunteers, that were age, gender and BMI matched, were included in the study. Blood samples were taken one per each volunteer on three different days to also assess variability of gene expression markers in one individual. In all datasets variability between volunteers was higher than variability of measurables in samples collected from the same volunteer on different days. We have identified genes in individuals that are highly stable during one month period and are thus suitable as markers of individual disease/therapy progress. A list of genes with low overall variability is also available. Interestingly, data show that important components of immune response are down-regulated with BMI in T helper and NK cells. This paper also gives the first insight into the gene expression profile of T helper and NK cells in healthy population. CD4 and NK lymphocytes were isolated with positive selection using magnetic nanoparticle based kits from StemCell Inc. (Canada) and frozen to -80°C until total RNA extraction.
