We examined the effect pg IGF1 actibation on cellular contractility and migration in SSC osteoblast cells. Based on microarray levels of IGF1 expression, we selected fifteen cases and nine controls spanning from the highest IGF1 expression to the lowest in cases and controls. Subsequently, the pattern of IGF1 expressions in these cells was assessed using high throughput RNA sequencing. Overall design: RNA-seq based gene expression profiling of fifteen SSC osteoblasts and nine control osteoblasts.
Activation of the IGF1 pathway mediates changes in cellular contractility and motility in single-suture craniosynostosis.

View SamplesExperiment: Establishment of expression profiles in a brain metastasis from a PTC (RNA processing and hybridization to Affymetrix microarray done twice to yield a technical replicate), in non-brain metastatic, stage III and IV PTCs, and primary brain tumors. Biostatistics analysis identified genes and biofunctions related to the brain metastatic PTC.
Microarray expression profiling identifies genes, including cytokines, and biofunctions, as diapedesis, associated with a brain metastasis from a papillary thyroid carcinoma.

View SamplesExperiment: Establishment of expression profiles in HT, PTC with HT, PTC without HT, and mPTC in comparison to TN samples. TN samples were downloaded as CEL files from the repository of the microarray vendor. Biostatistical analysis focussed in first instance on identifying genes and biofunctions related to HT and PTC with HT.

View SamplesExperiment: Expression profiling in breast cancer brain metastases (BC) compared to breast cancers (BC) and primary brain tumors (prBT). The objectives are to identify expression profiles that are specific to BCBM in order to identify new molecular biomarkers. The characterization of the BCBM samples included adjacent genetic techniques.

View SamplesPolycomb repressive complex-2 (PRC2) is a group of proteins that play important role during development and in cell differentiation. PRC2 is a histone-modifying complex that catalyses methylation of lysine 27 of histone H3 (H3K27me3) at differentiation genes leading to their transcriptional repression. JARID2 is a co-factor of PRC2 and is important for targeting PRC2 to chromatin as well as modulating its activity. Here, we show that in many human cells, including human epidermal keratinocytes, JARID2 predominantly exists as a novel low molecular weight form, which lacks the N-terminal PRC2-interacting domain (?N-JARID2). We show that ?N-JARID2 is a cleaved product of full-length JARID2 spanning the C-terminal conserved region consisting of jumonji domains. JARID2 knockout in keratinocytes results in up-regulation of cell cycle genes and repression of many epidermal differentiation genes. Surprisingly, repression of epidermal differentiation genes in JARID2-null keratinocytes can be relieved by expression of ?N-JARID2 suggesting that this form promotes activation of these genes and has opposing function to that of PRC2 in regulation of differentiation. We propose that a switch from expression of full-length JARID2 to ?N-JARID2 is important for the up-regulation of genes during differentiation. Overall design: RNA-seq analysis of Wildtype and JARID2-null keratinocytes (HaCaTs) on day 0 and day 3 of calcium induced differentiation.
A novel form of JARID2 is required for differentiation in lineage-committed cells.

View SamplesBackground: Epigenetic modifications such as methylation silencing of genes with CpG-island-associated promoters is frequently observed in cancer. Studies regarding the implications of epigenetic modifications in osteosarcoma (OS) have been limited. The epigenetic drug decitabine is a potential re-activator of silenced genes through de-methylation, and is currently undergoing clinical trials for cancer treatment. No study to date has utilized decitabine to modify gene expression in OS-derived cells to identify gene-specific methylation targets that may have therapeutic importance. The objective of this study was to measure the response of the OS cell line, U-2OS, to decitabine treatment both in vitro and in vivo.
Modulation by decitabine of gene expression and growth of osteosarcoma U2OS cells in vitro and in xenografts: identification of apoptotic genes as targets for demethylation.

View SamplesCumulus cells are biologically distinct from other follicular cells and perform specialized roles, transmitting signals within the ovary and supporting oocyte maturation during follicular development. The bi-directional communication between the oocyte and the surrounding cumulus cells is crucial for the acquisition of oocyte competence. Using Illumina/deep-sequencing technology, we dissected the small RNAome of pooled human mature MII oocytes and cumulus cells. Overall design: Cumulus cells and MII mature oocytes small RNA profiles were generated by deep-sequencing, using Illumina 1G sequencer
