Histone H3K4 trimethylation in rat peripheral nerve

Project description:ChIP-seq of H3K4me3 in rat peripheral nerve was used to identify transcription start sites associated with Schwann cell-expressed genes. The analysis was performed in injured and control nerve to identify injury-responsive changes in Schwann cells. H3K4me3 ChIP samples were prepared from rat sciatic nerve at 1 day post-transection using both the distal stump of the injured nerve and the contralateral (sham) nerve.

Evaluation of phenotypic plasticity in Rana temporaria tadpole development

Project description:Traditionally, the study of evolution has focused on heritable variation, because selection on non-heritable phenotypic variation was deemed non-important for its inability to cause evolutionary responses such as diversification of lineages. Recently however, it has been suggested that also environmentally induced phenotypic variation such as phenotypic plasticity can play an important role in adaptive responses resulting in diversification. The purpose of this study is to investigate the importance of phenotypic plasticity for the diversification of lineages, using life history, morphological traits, and genomic profiling during post embryonic development in plastic and non-plastic genotypes of the common frog Rana temporaria. Six animals each originating from four different islands were reared in either constant or reduced water conditions and hepatic mRNA levels of Gosner stage 37 animals evaluated by MAGEX DNA array analysis.

Exposure time during postembryonic development influences persistent biological effects of the insecticide carbaryl in green frogs (Lithobates clamitans)

Project description:The impact of pesticides on amphibian metamorphosis may vary depending on developmental stage of individuals during the exposure period. Some anurans experience increased rates of development when exposure to the insecticide carbaryl occurs later in larval development. We exposed developing northern green frog tadpoles (Lithobates clamitans) to a 3 day pulsatile exposure of 1 mg/L carbaryl at 16 weeks relative to the starting free-swimming Gosner stage 25 (Gosner, 1960) and examined treatment effects on brain mRNA abundance profiles of Gosner stage 46 metamorphs using an amphibian cDNA microarray. Five individuals from control non exposed tadpoles and six animals that had been exposed transiently for 3 days to carbaryl at week 16 and allowed to continue development until Gosner stage 46 were randomly selected for analysis of brain mRNA levels evaluated using the MAGEX DNA microarray.

Cell surface mapping and monitoring of cell surface dynamics

Project description:Here, we present a simple and robust N-linked glycoproteome enrichment protocol optimized for deep coverage of the plasma membrane proteome. The procedure was applied to characterize the cell surface proteome of 15 standard laboratory human cell lines and three primary cell types. We observed significant differences in receptor diversity and transporter abundances between primary cells and corresponding cell lines. Relative quantification using isobaric mass tagging enabled quantitative monitoring of dynamic processes on the cell surface in multiplexed experiments. We for the first time report a comprehensive analysis of the profound remodeling of the plasma membrane proteome during monocyte to macrophage differentiation of THP-1 cells. Treatment of these cells with the kinase inhibitor dasatinib (Sprycel) during differentiation severely compromised macrophage differentiation due to an off-target activity resulting in substantial morphological and functional changes and the loss of many macrophage-associated proteins.

Genome-wide profiling of follicular lymphoma by array comparative genomic hybridization

Project description:The secondary genetic events associated with follicular lymphoma (FL) progression are not well defined. We applied genome-wide BAC array comparative genomic hybridization to 106 diagnostic biopsies of FL to characterize regional genomic imbalances. Using an analytical approach that defined regions of copy number change as intersections between visual annotations and a Hidden Markov model-based algorithm, we identified 71 regional alterations that were recurrent in â?¥10% of cases. These ranged in size from ~200 kb to 44 Mb, affecting chromosomes 1, 5, 6, 7, 8, 10, 12, 17, 18, 19, and 22. We also demonstrated by cluster analysis that 46.2% of the 106 cases could be sub-grouped based on the presence of +1q, +6p/6q-, +7 or +18. Survival analysis showed that 21 of the 71 regions correlated significantly with inferior overall survival (OS). Of these 21 regions, 16 were independent predictors of OS using a multivariate Cox model that included the International Prognostic Index (IPI) Score. Two of these 16 regions (1p36.22-p36.33 and 6q21-q24.3) were also predictors of transformation risk and independent of IPI. These prognostic features may be useful to identify high-risk patients as candidates for risk-adapted therapies.

Transcription profiling of fission yeast strains identifies widespread requirement for SWI/SNF and RSC on transcription

Project description:SWI/SNF chromatin remodeling complexes play critical roles in transcription and other chromatin-related processes. The analysis of the two members of this class in Saccharomyces cerevisiae, SWI/SNF and RSC, has heavily contributed to our understanding of these complexes. To understand the in vivo functions of SWI/SNF and RSC in an evolutionarily distant organism, we have characterized these complexes in Schizosaccharomyces pombe. While core components are conserved between the two yeasts, the compositions of S. pombe SWI/SNF and RSC differ from their S. cerevisiae counterparts and in some ways are more similar to metazoan complexes. Furthermore, several of the conserved proteins, including actin-like proteins, are strikingly different between the two yeasts with respect to their requirement for viability. Finally, phenotypic and microarray analyses identified widespread requirements for SWI/SNF and RSC on transcription including strong evidence that SWI/SNF directly represses iron transport genes.

Transcription profiling of hip1::ura4+ and slm9::ura4+ S. pombe to investigate the role of the HIRA histone chaperone complex

Project description:The assembly of nucleosomes by histone chaperones is an important component of transcriptional regulation. Here we have assessed the global roles of the S. pombe HIRA histone chaperone complex. Microarray analysis indicates that inactivation of the HIRA complex results in increased expression of at least 4% of fission yeast genes. HIRA-regulated genes overlap with those which are normally repressed in vegetatively growing cells, such as targets of the Clr6 histone deacetylase and silenced genes located in subtelomeric regions. HIRA is also required for silencing of all 13 intact copies of the Tf2 long terminal repeat (LTR) retrotransposon. However, the role of HIRA is not restricted to bona fide promoters, because it also suppresses non-coding transcripts from solo LTR elements and spurious antisense transcripts from cryptic promoters associated with transcribed regions. Furthermore, the HIRA complex is essential in the absence of the quality control provided by nuclear exosome-mediated degradation of illegitimate transcripts. This suggests that HIRA restricts genomic accessibility, and, consistent with this, the chromosomes of cells lacking HIRA are more susceptible to genotoxic agents that cause double strand breaks. Thus the HIRA histone chaperone is required to maintain the protective functions of chromatin.
