Transcriptional profiling by microarray of microRNAs of osteoblastic cells from calvaria and bone marrow of ovariectomized rats.

ABSTRACT: The microRNA oligo microarrays from Agilent were used to evaluate behavioral differences in osteoblast-like cells from calvaria and bone marrow of rats induced to osteoporosis by ovariectomy. The miRNAs data were normalized using the quantile and after statistical analysis by moderate t-test with p-value ≤ 0.05 and subsequent fold change ≥ 1.5, 84 miRNAs differentially expressed in calvaria cells were detected and 55 miRNAs in bone marrow cells.

Identification of mirna during osteoblast differentiation of human dental pulp stem cells

Project description:To evaluate the miRNA and mRNA expression profiles (miRNOME) we identified miRNAs during in vitro osteogenic differentiation of human dental pulp stem cells (DPSC). The DPSCs were cultured in the DMEM + beta-glycerol phosphate, ascorbic acid and dexamethasone for 2 dias to 21days. The microRNA or mRNA expression profiling during the differentiation process was analyzed through hybridizations with Agilent miRNA-microarray (8x15K format).

The effect of the Autoimmune regulator (Aire) gene on microRNA transcriptional profile of 3.10 mTEC cell line

Project description:Medullary thymic epithelial cells (mTECs) contribute to self-tolerance through the ectopic expression of peripheral tissue antigens (PTAs) in the thymus. Autoimmune regulator (Aire) is to date the best characterized transcriptional regulator known to at least partially coordinate PTA expression in mTECs. Furthermore the expression of Aire-dependent and -independent genes is also modulated by microRNAs. Given the transcriptional regulation exerted by Aire in mTEC cells and the role of miRNAs in post-transcriptional control, we used a Mus musculus mTEC cell line (3.10) which constitutively express Aire in culture) to knockdown Aire gene by means of siRNA transfection and then observe the effect of Aire knockdown in the transcriptional profile of miRNAs by means of oligomicroarrays. The Agilent oligomicroarrays were used to determine the large scale the miRNA transcriptional profiles of control or Aire-knockdown 3.10 mTECs.

The effect of Dicer knockdown on the microRNA transcriptional profile of 3.10 mTEC cell line.

Project description:Dicer, also known as endoribonuclease Dicer or helicase with RNase motif, cleaves double-stranded RNA (dsRNA) and pre-microRNA (pre-miRNA) into short mature double-stranded RNA fragments called small interfering RNA and microRNA, respectively. MicroRNAs are potent post-transcriptional regulators in developmental switches, lineage commitment and gene expression regulation. To evaluate their post-transcriptional role in gene expression of Medullary thymic epithelial cells (mTECS) we knocked down Dicer transcript by means of siRNA transfection in a Mus musculus mTEC cell line (3.10 mTEC). The Agilent oligo microarrays were used to determine the large scale microRNA (miRNA) transcriptional profiles of control or Dicer-knockdown 3.10 mTECs.

Transcription profiling of aortic samples from newborn and 6 week old C57/black6 wild type mice

Project description:Aortic samples ranging from the aortic valve to the diaphragm were harvested from 15 newborn and 15 six-week old C57/black6 wildtype mice. Frozen samples of 5 animals each were pulverized and directly dissolved in RNA pure (PeqLab) to get three samples for each group. Total RNA was isolated using phenol/chloroform extraction.<br><br>For gene-expression analysis, 500 ng total RNA of each RNA sample was labeled using the Agilent single-color Quick-Amp Labeling Kit and hybridized on Agilent Whole Mouse Genome Microarrays (4x44K). For<br><br>analysis of microRNA, 200 ng total RNA of each sample was labeled using the Agilent miRNA Labeling Reagent and Hyb Kit, and hybridized on Agilent Mouse miRNA Microarrays (8x15K) according to the manufacturer's instructions.

The purpose of the experiment was to study miRNA expression in prostate cancer cell lines and xenografts and to combine it with miRNA gene copy number data that we already had to identify miRNAs that could be overexpressed or underexpressed as a consequence of amplification or deletion of the miRNA gene, respectively.
