Project description:Purpose: Evaluation of differential expression using Illumina HiSeq 2500 analysis of RNA of pure cultures of H. congolense grown in biofilms on various surfaces to assess the impact of surface type on transcriptome.
Project description:Pure cultures of S. aciditrophicus grown in 250 ml of 20 mM crotonate medium in 500-ml Schott bottles were used for proteomic analysis after 2-dimensional (2-D) PAGE.
Project description:Transcription profile of Escherichia coli cells in mono-species pure planktonic cultures was compared to that of E. coli cells in E. coli-Stenotrophomonas maltophilia dual-species planktonic cultures E. coli cells were separated from dual-species planktonic cultures before total RNA extraction to eliminate possible cross hybridization from S. maltophilia transcripts. The separation method was developed by combining the use of reagent RNAlater and immuno-magnetic separation. Pure E. coli planktonic cultures were processed with the same separation protocol before RNA extraction.
Project description:Parietal epithelial cells (PECs) are crucially involved in the pathogenesis of rapidly progressive glomerulonephritis (RPGN) as well as in focal and segmental glomerulosclerosis (FSGS). In this study, transgenic mouse lines were used to isolate pure, genetically tagged primary cultures of PECs or podocytes using FACsorting. By this approach, the morphology of primary glomerular epithelial cells in culture could be resolved: Primary podocytes formed either large cells with intracytoplasmatic extensions or smaller spindle shaped cells, depending on specific culture conditions. Primary PECs were small and exhibited a spindle-shaped or polygonal morphology. In the very early phases of primary culture, rapid changes in gene expression (e.g. of WT-1 and Pax-2) were observed. However, after prolonged culture primary PECs and podocytes still segregated clearly in a transcriptome analysis - demonstrating that the origin of primary cell cultures is important. Of the classical markers, synaptopodin and podoplanin expression were differentially regulated the most in primary PEC and podocyte cultures. However, no expression of any endogenous gene allowed to differentiate between the two cell types in culture. Finally, we show that the transcription factor WT1 is also expressed by PECs. In summary, genetic tagging of PECs and podocytes is a novel and necessary tool to derive pure primary cultures with proven origin. These cultures will be a powerful tool for the emerging field of parietal epithelial cell biology.
Project description:This dataset has been used to establish GroEL-SIP, coupling a targeted proteotyping approach for assessing bacterial community compositions using the taxonomic marker protein GroEL with stable isotope probing to link the identified taxa to substrate assimilation. This dataset contains raw data of four experiments: 1.) Pure cultures of T. aromatica cultivated with 13C or 12C benzoate mixed in defined ratios. 2.) Pure cultures of P. putida cultivated with 13C or 12C benzoate mixed in a 1:1 ratio. 3.) Pure cultures of E. coli cultivated with 12C acetate and 13C or 12C benzoate mixed in a 1:1 ratio. 4.) Co-cultivated biculture of T. aromatica and P. putida cultivated with 13C or 12C benzoate and mixed in a 1:1 ratio. 5.) Co-cultivated biculture of T. aromatica and E. coli cultivated with 12c acetate and 13C or 12C benzoate and mixed in a 1:1 ratio. 1)-3) were analyzed after in-solution digestion 4)-5) were analyzed after in-gel digestion of the 60 kDa band
Project description:Whole transcriptome comparisons of proliferating pure cultures of neonatal dermal microvacsular endothelial cells to infantile hemangioma endothelial cells. The total RNA was obtained from human dermal microvascular endothelial cells and infantile hemangioma endothelial cells. Illumina microarrays were performed to determine the whole genome expression differences between the cell lines.
Project description:We developed a method that allows measuring the stable carbon isotope composition of individual species in microbial communities using metaproteomics. We call this methods “Direct Protein-SIF”. To benchmark this method, we measured twenty pure culture species using the Direct Protein-SIF method as well as Isotope Ratio Mass Spectrometry. Some of the pure cultures were measured in technical replicates to see how consistent Protein-SIF measurements are between mass spec runs. This submission thus contains 29 raw files for the pure cultures. See table in the submission for details of which species was measured for which .raw file. We also included the Direct Protein-SIF specific isotope pattern files as well as the .mzML files and PSM files required as input for the Direct Protein-SIF software. In addition to the pure culture a protein reference material (MKH files) was measured. The respective .raw files and isotopic pattern files are also included in this submission (see publication for details on how the reference material is used to calibrate the method).
Project description:To understand the behaviour in terms of special genome components that are expressed by L.monocytogenes in the presence of another bacterium as may be the condition in its natural environments was our objective, for which we have used microarray gene expression at different time intervals of growth from 4hrs to 24 hrs. Expression of L.monocytogenes as co-cultures, both in broth culture state and biofilm state were differentiated to that of 24hrs pure broth culture. Also genes regulated for and during biofilm formation as pure cultures were identified with comparision to 24hrs pure broth culture. Distinguishing features with notable variation in all of the three sample sets as L.monocytogenes in pure culture biofilm, co-culture broth and co-culture biofilm were observable. Genes that are specifically up-regulated at each of growth condition and time interval were identified, genes regulated with ascending and descending patterns in time were also noticable. These variation in the gene expression gives an insight into the alterations in the biosynthetic and metabolic pathways under different states of growth
