Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Studies of gene expression profiles using the whole genome wide microarray analysis in SUM149PT cells (ER-, p53mut) and SUM190PT cells (ER-, p53mut) when treated with 5 or 7.5 M CG-1521 alone and in combination with 10 nM 17-Estradiol. Comparisons between each treatment group provides evidence for the dysregulation of genes associated with the spindle assembly checkpoint.

Description
UMR106-01 osteoblastic cells are a model for studying bone mineralization. We have shown that mineralization is temporally synchronized within cultures grown under defined conditions . Cells are plated at time zero and differentiate into osteoblastic phenotype by 64 h later. If an exogenous phosphate source is added to the cultures, the cells form and deposit hydroxyapatite mineral within distinct extracellular supramolecular lipid protein complexes termed biomineralization foci (BMF) starting 12 h later. Mineralization is largely complete by 24 h later (88 h after plating). We have also shown that AEBSF, covalent serine protease inhibitor, blocks mineralization within BMF and inhibits the fragmentation of several proteins related to biomineralization. The present experiment was designed to test whether AEBSF treatment for 12 h has an effect on transcription by UMR106-01 osteoblastic cells. AEBSF is known to inactivate several serine proteases including SKI-1 (site 1, subtilisin kexin protease-1).SKI-1 functions intracellularly to activate transmembrane bound transcription factor precursors releasing the transcriptionally active N-terminal portions to imported into the nucleus. Thus, if AEBSF blocks transcription of mineralization related genes, it would support a role for SKI-1 in gene regulation in mineralizing UMR106-01 osteoblastic cells.

Illumina HiSeq 2500
Description
Purpose: identification of mRNAs that are potential targets of miR-203 in the endometrium and endometrial carcinoma Methods: mRNA profiles of three batches of wild-type (WT) and three independently generated miR-203 knockout (miR-203 KO) RUCA-I cells were produced by deep sequencing, using Illumina HiSeq 2500. The sequence reads that passed quality filters were analyzed at the transcript isoform level with TopHat followed by Cufflinks. Results: Using an optimized data analysis workflow, we mapped between 30 and 50 million sequence reads per sample to the rat genome (build rn6) and identified 26751 transcripts of which 1591 are differentially expressed in WT and miR-203 KO cells (p<0.05). Overall design: mRNA profiles of three WT batches and three independently generated miR-203 KO RUCA-I rat endometrial adenocarcinoma cell lines were produced by deep sequencing, using Illumina HiSeq2500.

- Affymetrix Human Exon 1.0 ST Array [transcript (gene) version (huex10st)
Description
The gene expression pathways leading to muscle pathology in facioscapulohumeral dystrophy (FSHD) remain to be elucidated. This muscular dystrophy is caused by a contraction of an array of tandem 3.3-kb repeats (D4Z4) at 4q35.2. We compared expression of control and FSHD myoblasts and myotubes (three preparations each) on exon microarrays (Affymetrix Human Exon 1.0 ST) and validated FSHD-specific differences for representative genes by qRT-PCR on additional myoblast cell strains. The FSHD and control myoblasts used for these experiments were shown to grow and differentiate into myotubes equally efficiently as control myoblasts. There were no significant FSHD-control differences in RNA levels for MYOD1 and MYOG at the myoblast and myotube stages and for MYF5 and MYF6 at the myoblast stage. In contrast, 295 other genes were dysregulated at least 2-fold in FSHD vs. control myoblasts (p <0.01, adjusted for multiple comparisons).

Description
Thrombospondin 1 (TSP-1) is an anti-angiogenic matricellular protein with regulatory functions in inflammation and cancer. The type 1 repeats (TSR) domains of TSP-1 have been shown to interact with a wide range of proteins that result in the anti-angiogenic and anti-tumor properties of TSP-1. To evaluate potential therapeutic effects of TSRs in inflammatory bowel disease, we conducted clinical, histological and gene microarray analyses on a mouse model of induced colitis.

Description
Purpose of arrays were to determine what the effect of deletion of Mbtps1 gene was on gene expression of osteocytes in bone in vivo. DMP1 cre driver was used to delete the Mbtps1 gene in osteocytes and osteoblasts in bone. We then isolated osteocyte enriched bone particles from 40 week old male mice to determine the effect of this deletion on gene expression. We have previously shown that Mbtps1 is needed for transcription of Phex, DMP1, and MEPE genes in osteoblasts in culture. Arrays showed these genes were reduced as expected in osteocytes in vivo. Controls represent osteocyte enriched bone from 40 week old littermates. Also, as expected, Mbtps1 expression was reduced in these knockout mice

Description
The study was performed to determine if there were alterations in the total RNA pool among the epidermal keratinocytes of K14 promotor-driven noggin overexpression compared with K14 promotor-driven BMP4 overexpression transgenic animals, which will directly relate to cellular chemistry and immune and sensory function. The total study is also aimed at determining alterations of transcrption factors and/or regulation of gene function, including methylation states and micro RNA control in keratinocytes following sensory challenge, particularly neuropathic and chronic pain conditions.
