Project description:Acidified seawater not only resulted in the less settlement of A. gemmifera embryos, but also decreased juvenile sizes and slowed the development of skeleton. The solute carriers (SLC) (membrane transport proteins) responsible for the calcium and bicarbonate transports were downregulated due to elevated CO2.

Project description:To investigate the mechanism of histamine H1 receptor (H1R)- mediated proliferation and angiogenesis of endothelial cells, mRNA profiles of HUVEC cells transduced with shNT or shH1R under histamine treatment for 9 hrs were generated by deep sequencing, in replicate, using Illumina GAIIx. We identified the upregulation of genes in several pathways including angiogenesis, proliferation and migration that could be responsible for the increased tube formation in histamine treated shNT expressing HUVEC cells

Project description:Transporters such as solute carriers (SLCs) are required to transport substrates such as nutrients or metals across cellular membranes. We here aimed to indentify which transporters are required for the proliferation of HCT116 WT and KO cells (SLC16A1, SLC16A3, SLC16A13, SLC25A28, SLC25A37 and SLC6A8 KOs).

Project description:The advent of high-throughput measurements of gene expression and bioinformatics analysis methods offers new ways to study gene expression patterns. The primary goal of this study was to determine the time sequence for gene expression in a bone subjected to mechanical loading, during key periods of the bone formation process, including expression of matrix-related genes, the appearance of active osteoblasts, and bone desensitization. A standard model for bone loading was employed in which the right forelimb was loaded axially for three minutes per day, while the left forearm served as a non-loaded, contralateral control. We evaluated loading-induced gene expression over a time course of 4 hours to 32 days after the first loading session. Six distinct, time-dependent patterns of gene expression were identified over the time course and categorized into three primary clusters: genes upregulated early in the time course, genes upregulated during matrix formation, and genes downregulated during matrix formation. Genes were then grouped based on function and/or signaling pathways. Many gene groups known to be important in loading-induced bone formation were identified within the clusters, including AP-1-related genes in the early response cluster, matrix-related genes in the upregulated gene clusters, and Wnt/?-catenin signaling pathway inhibitors in the downregulated gene clusters. Several novel gene groups were identified as well, including chemokine-related genes which were upregulated early but downregulated later in the time course, solute carrier genes which were both up- and downregulated, and muscle-related genes which were primarily downregulated. Time Course with 11 time points, each plus & minus mechanical stimulation with 5 replicates per experimental group (except 12d group which has 4 replicates). Daily mechanical loading was applied to the forearm (24 hours between loading sessions), and ulnae were sampled at indicated time points (4h, 12h, 1d, 2d, 4d, 6d, 8d, 12d, 16d, 24d, or 32d).

Project description:Endocrine cells employ regulated exocytosis of secretory granules to secrete hormones and neurotransmitters. Secretory granule exocytosis depends on spatio-temporal variables such as proximity to the plasma membrane and age, with newly-generated granules being preferentially released. Despite recent advances, we lack a comprehensive view about the molecular composition of insulin granules and associated changes over their lifetime. Here we report a strategy for the purification of insulin secretory granules of distinct age from insulinoma INS-1 cells. Tagging the granule-resident protein phogrin with a cleavable CLIP tag, we obtain intact fractions of age-distinct granules for proteomic and lipidomic analyses. We find that the lipid composition changes

Project description:We previously showed that transgenic enhancement of histamine production in B16-F10 melanomas strongly supports tumor growth in C57Bl/6 mice (Cancer Res, 2005 Pos et al.). In this array experiment, gene expression profiles of transgenic mouse melanomas, secreting different amounts of histamine, were compared by whole genome microarrays. Experiment Overall Design: By modifying the levels of L-histidine decarboxylase (HDC), the sole enzyme responsible for histamine production, we introduced three novel variants of the B16-F10 mouse melanoma cell line, displaying diminished (B16-F10 HDC-A), unmodified (B16-F10 HDC-M) or enhanced (B16-F10 HDC-S) capacities to produce and secrete histamine. Experiment Overall Design: In this experiment, B16-F10 HDC-A, HDC-M, and HDC-S experimental mouse melanomas were compared by analyzing 6-6 tumors in each group. Experiment Overall Design: In order to reduce the amount of arrays required, equal amounts of randomly chosen RNA sample pairs were pooled in each group, thus, at the end, each group consisted of 3 pooled tumor samples. All samples were biological replicates, no technical replicates or dye swapping were done. Experiment Overall Design: Gene expression patterns of the three tumor groups were compared indirectly, via a common reference samplei n a two-color array design. Arrays shown here represent gene expression patterns of individual tumor samples compared to the reference sample.

Project description:The functions of cohesin are central to genome integrity, chromosome organization, and transcription regulation through its prevention of premature sister-chromatid separation and the formation of DNA loops. The loading of cohesin onto chromatin depends on the Scc2-Scc4 complex, however, little is known about how it stimulates the cohesin loading activity. Here we determine the large “hook” structure of Scc2 responsible for catalyzing cohesin loading. We identify key Scc2 surfaces that are crucial for DNA binding and for cohesin loading in vivo. Using previously determined structures and modeling, we derive a pseudo-atomic structure of the full-length Scc2-Scc4 complex. Finally, our crosslinking and electron microscopy analyses reveal that Scc2-Scc4 utilizes its modular structure to make multiple contacts with a folded cohesin at an interface created by the cohesin head-hinge interaction.

Project description:Because lymphoid progenitors can give rise to natural killer (NK) cells, NK ontogeny has been considered to be exclusively lymphoid. Here, we show that rare human CD34(+) hematopoietic progenitors develop into NK cells in vitro in the presence of cytokines (interleukin-7, interleukin-15, stem cell factor, and fms-like tyrosine kinase-3 ligand). Adding hydrocortisone and stromal cells greatly increases the frequency of progenitor cells that give rise to NK cells through the recruitment of myeloid precursors, including common myeloid progenitors and granulocytic-monocytic precursors to the NK-cell lineage. WNT signaling was involved in this effect. Cells at more advanced stages of myeloid differentiation (with increasing expression of CD13 and macrophage colony-stimulating factor receptor [M-CSFR]) could also differentiate into NK cells in the presence of cytokines, stroma, and hydrocortisone. NK cells derived from myeloid precursors (CD56(-)CD117(+)M-CSFR(+)) showed more expression of killer immunoglobulin-like receptors, a fraction of killer immunoglobulin-like receptor-positive-expressing cells that lacked NKG2A, a higher cytotoxicity compared with CD56(-)CD117(+)M-CSFR(-) precursor-derived NK cells and thus resemble the CD56(dim) subset of NK cells. Collectively, these studies show that NK cells can be derived from the myeloid lineage.
