State transition is a dynamic process to balance the amount of light energy received by photosystem I (PSI) and photosystem II (PSII) so as to maintain an optimal photosynthetic yield and to minimize photo-damage in a fluctuating light environment. Recent studies show that chloroplast acetyltransferase participates in the acetylation of photosynthetic proteins and state transitions. However, the exact molecular mechanisms are poorly understood. In this study, we characterized a chloroplast acety ...[more]

Mass spectrometry reflects key aspects of copper-amyloid β chemistry

Project description:In this study, we examined the gas-phase redox chemistry of the [copper(II) – amyloid β] complex. Our findings reveal that the sequence-dependent variations in this chemistry correspond to significant aspects of the in vitro behavior of different peptide variants.

Transcription profiling of mouse B16-F10 melanoma cells transfected with FoxD3

Project description:We wished to examine the genes regulated by FoxD3 in pigment cells to gain understanding in how FoxD3 represses melanoblast specification in the neural crest. For technical reasons, we could not use neural crest cells, so we used melanoma cells, since they are derived from neural crest cells. To this end, we transfected B16-F10 mouse melanoma cells with constructs expressing FoxD3, or FoxD3-VP16, in which the C-terminal portion of FoxD3 (which contains the transcriptional repression domain) has been replaced by the VP16 transcriptional activation domain. Experiment Overall Design: The base vector used for these studies was pMES, which expresses the gene of interest under control of the chick beta-actin promoter. EGFP is also expressed from the bicistronic mRNA through the use of an IRES. Experiment Overall Design: B16-F10 cells were transfected with either empty pMES, pFoxD3 (which contains FoxD3 inserted into pMES), or pFoxD3-VP16 (similar to pFoxD3, except that the C-terminal portion of FoxD3, which contains the transcriptional repression domain, has been replaced by the transcriptional activation domain of VP16). Experiment Overall Design: 24 hours after transfection, EGFP-positive cells were collected by FACS and those cells were subjected to microarray analysis.

ChIP-seq analysis reveals distinct H3K27me3 profiles associated with gene regulation [ChIP-seq]

Project description:Transcriptional control is dependent on a vast network of epigenetic modifications. One epigenetic mark of particular interest is tri-methylation of lysine 27 on histone H3 (H3K27me3), which is catalyzed and maintained by the Polycomb Repressor Complex (PRC2). Although this histone mark is studied widely, the precise relationship between its local pattern of enrichment and regulation of gene expression is currently unclear. We have used ChIP-seq to generate genome wide maps of H3K27me3 enrichment, and have identified three enrichment profiles with distinct regulatory consequences. First, a broad domain of H3K27me3 enrichment across the body of genes corresponds to the canonical view of H3K27me3 as inhibitory to transcription. Second, a peak of enrichment around the transcription start site is commonly associated with â??bivalentâ?? genes, where H3K4me3 also marks the TSS. Finally and most surprisingly, we identified an enrichment profile with a peak in the promoter of genes that is associated with active transcription. Genes with each of these three profiles were found in different proportions in each of the cell types studied. The data analysis techniques developed here will be useful for the identification of common enrichment profiles for other histone modifications that have important consequences for transcriptional regulation. Genomic DNA was extracted from ES cells and G1ME cells in mouse. ChIP-seq with antibodies for H3K27me3, RNApol-II were run for both cell types. As a control, whole cell extract or Input DNA was also sequenced for both cell types without the inclusion of an antibody.

STING mediates lupus via the activation of conventional dendritic cell maturation and plasmacytoid dendritic cell differentiation

Project description:BMDCs from WT, Fcgr2b-/- and Stinggt/gt were cultured, then stimulated with DMXAA for 3 and 6 hr. Cells were collected and lysed with 1 % IGEPAL CA-630, 0.5% TritonX-100, 150 mM NaCl, 50 mM Tris pH 7.4, 5% glycerol, 100 mM beta-Glycerophosphate, 2 mM Na3VO4 and 1X proteases inhibitor cocktail (Roche). First, antibody were mixed with the magnetic beads by adding 10 µg of STING antibody with 400 ug of SureBeads™ Protein A magnetic beads (Biorad, California, USA) and incubated for 1 hour at room temperature. Then, Protein lysates were added and incubated with antibody-conjugated beads for overnight at 4oC. After incubation, the beads were washed 3 times with wash buffer (150 mM NaCl and 50 mM Tris-HCL pH 7.4). Samples were eluted by adding 5X laemmli buffer and, boiled 950C for 10 minutes. The eluted protein samples were separated by 10 % SDS-PAGE gel. The STING interacting proteins from co-IP were analyzed by in-gel digestion followed by LC-MS/MS analysis.

Maturation kinetics of a multiprotein complex revealed by metabolic labeling

Project description:The project aims at computing in vivo co-assembly kinetics from metabolomic-inspired approaches. In short, we performed reciprocal pull-down experiments from complex cellular components at different time points following pulsed-SILAC metabolic labeling. We applied the method to 320 pairs of yeast nucleoporin (NUP) proteins constituting the ~ 50 MDa Nuclear Pore Complex (NPC). Our analysis reveals a hierarchical principle of the NPC biogenesis where individual subcomplexes form on a minute time-scale, followed by their co-assembly from central to peripheral subunits in a ~ 1 hour long maturation process.
