ABSTRACT: Prevotella bryantii B14 was cultivated with monensin. Growth was monitored over a period of 9h with a broad range of monensin concentrations.
Project description:Prevotella bryantii B14 was cultivated with monensin. Growth was monitored over a period of 72h including frequent sampling of cells.
Project description:P. bryantii B14 cells were cultivated separately in acetic (Acet), propionic (Prop), butyric (But), iso-butyric (iBut), valeric (Val), iso-valeric (iVal) and 2-methyl butyric acid (2MB) as well as in a mixture of all mentioned short-chain fatty acids (Mix). All 8 treatments were analyzed regarding their proteomes in order to understand the requirements and effects of each SCFA on the metabolism.
Project description:Gene expression profiles of human immature dendritic cells after 3h, 6h, 9h and 12h of co-cultivation with Aspergillus fumigatus were compared to expression profiles from human immature dendritic cells after 3h, 6h, 9h and 12h of cultivation.
Project description:Transcriptional profiling of Schmidtea mediterranea planarians that have been subjected to 2 weeks of runt-1 or control RNAi, amputated and RNA was directly collected at 5min, 9h, and 24h, or neoblasts (X1) were isolated from 9h wounded animals and subsequently RNA was extracted
Project description:The aim of the present work was to investigate the effect of monensin on the in vitro growth of T. gondii tachyzoites and on the host cells (human brain microvascular endothelial cells - hBMECs). The hypotheses were that (1) inhibition of the WNT signalling pathway by monensin can reduce the growth of T. gondii infecting human brain microvascular endothelial cells (hBMECs) and (2) by suppression of the growth of T. gondii using monensin, impairment of the BBB integrity can be restored (3) inhibition of WNT pathway by monensin can be detected by microarray experiment.
Project description:Prevotella species in the human gut microbiome are primarily comprised of Prevotella copri, and its diversity and function were recently investigated in detail. Much less is known about other Prevotella species in the human gut. Here, we examined the composition of Prevotella species in human guts by mapping publicly available gut metagenomes to a dereplicated set of metagenome-assembled genomes (MAGs) representing Prevotella lineages found in human guts. In most human cohorts, P. copri is the most relatively abundant species (e.g. up to 14.3% relative abundance in Tangshan, China). However, more than half of the metagenome reads in several cohorts mapped to Prevotella MAGs representing P. stercorea and several other species sister to P. stercorea and P. copri. Analyses of genes encoded in these genomes indicated that P. stercorea and related lineages lacked many hemicellulose degrading enzymes and were thus less likely to metabolise hemicelluloses compared with P. copri and copri-related lineages. Instead, P. stercorea genomes possess several carbohydrate esterases that may be involved in releasing ester modifications from carbohydrates to facilitate their degradation. These findings reveal unexplored Prevotella diversity in the human gut and indicate possible niche partitions among these related species.
Project description:In contrast to most filamentous fungi, A. gossypii displays <br>a very simple haploid life cycle. This is a transcriptome analysis <br>of A. gossypii at different developmental stages. Individual transcription profiles<br>were developed from spores to bipolar germlings (time<br>frame 9 h), from bipolar germlings to advanced mycelia<br>and to very fast growing hyphae (time frame 9h and 4 d, <br>respectively) and from very fast growing hyphae to <br>sporulating mycelium (time frame 2 d).
Project description:Our preliminary findings lead us to propose bone marrow adipocyte secretions as new actors of bone loss. Indeed, using a coculture model based on human bone marrow stromal cells, we previously showed that soluble factors secreted by adipocytes induced the conversion of osteoblasts towards an adipocyte-like phenotype. To further decipher the molecular changes triggered by the coculture, we performed transcriptional analyses using Agilent 60-mer Sure Print G3 Human Gene Expression Microarray Kit containing a 50, 599 probes. Transcriptional changes were monitored in 7 biological replicates each consisting of osteoblasts grown alone (OB) and cocultured osteoblasts (OB-CC) upon 9h or 48h and adipocytes (AD) at day 14 of differentiation placed in serum-free medium for 9h or 48h.
Project description:Gene expression profiles of human immature dendritic cells after 3h, 6h, 9h and 12h of co-cultivation with Aspergillus fumigatus were compared to expression profiles from human immature dendritic cells after 3h, 6h, 9h and 12h of cultivation. We used microarrays to detail the gene expression of human immature dendritic cells after 3h, 6h, 9h and 12h of co-cultivation with Aspergillus fumigatus
