Identification of differentially expressed microRNA in human alveolar bone cells cultured on different titanium surfaces.

ABSTRACT: To evaluate miRNA expression profile (miRNOME), we identified microRNAs of osteoblastic cells from human alveolar crest culture in contact with different titanium surfaces: control (polished), nanotextured (polished titanium discs, etching at 25°C with 50% H2SO4conc and 50% H2O2aq) , nano+submicrotextured (polished titanium discs, etching at 50°C with 50% H2SO4conc and 50% H2O2aq) and rough microtexture (polished titanium discs, etching at 50°C with 100% H2O2aq). The osteoblastic cells were cultured in the alpha-minimum essential medium, supplemented with fetal bovine serum, gentamicin, fungizone, dexamethasone, ascorbic acid and β-glycerophosphate. The microRNA expression profiling was analyzed through hybridizations with Agilent miRNA-microarray (8x15K format).

Identification of differentially expressed genes in human alveolar bone cells cultured on different titanium surfaces.

Project description:To evaluate mRNA expression profile (transcriptome), we identified mRNAs of osteoblastic cells from human alveolar crest culture in contact with different titanium surfaces: control (polished), nanotextured (polished titanium discs, etching at 25oC with 50% H2SO4conc and 50% H2O2aq) , nano+submicrotextured (polished titanium discs, etching at 50oC with 50% H2SO4conc and 50% H2O2aq) and rough microtexture (polished titanium discs, etching at 50oC with 100% H2O2aq). The osteoblastic cells were cultured in the alpha-minimum essential medium, supplemented with fetal bovine serum, gentamicin, fungizone, dexamethasone, ascorbic acid and β-glycerophosphate. The mRNA expression profiling was analyzed through hybridizations with whole-human genome Agilent microarray (4x44K format).

Identification of netwoks mirna-mrna interactions during osteoblast differentiation of human dental pulp stem cells

Project description:To evaluate the miRNA and mRNA expression profiles (miRNOME and transcriptome) we reconstructed networks identifying miRNAs and mRNA 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 to 21 days. The microRNA or mRNA expression profiling during the differentiation process was analyzed through hybridizations with Agilent miRNA-microarray (8x15K format) or whole-human genome Agilent microarray (4x44K format).

The effect of the autoimmune regulator (Aire) gene on the transcriptional expression 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. PTA expression in mTECs is largely dependent on the autoimmune regulator (Aire) gene. Here we used a Mus musculus mTEC cell line (3.10 mTEC line, which constitutively express Aire in culture) to knockdown Aire gene by means of siRNA transfection. Aire knockdown was confirmed by means of qRT-PCR and RNA-FISH (for Aire mRNA levels), immunofluorescence and western blot (for AIRE protein levels).The Agilent oligo microarrays were used to determine the large scale transcriptional expression profiles of control or Aire-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. 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 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 effect of Dicer knockdown on the transcriptional expression 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. Medullary thymic epithelial cells (mTECs) express close to 90% of the protein-coding genome, besides they play an important role to self-tolerance through the ectopic expression of peripheral tissue antigens (PTAs) in the thymus. MicroRNAs are potent post-transcriptional regulators in developmental switches, lineage commitment and gene expression regulation, but their role in representation of the immunological self in mature mTECs is not fully understood. So we used a Mus musculus mTEC cell line (mTEC 3.10) to knockdown Dicer transcript by means of siRNA transfection and then observe the effect of Dicer knockdown in the transcriptional profile of messenger RNAs (mRNAs) by means of oligo microarray hybridization. The Agilent oligo microarrays were used to determine the large scale mRNA transcriptional profiles of control or Dicer-knockdown 3.10 mTECs.

Intubated patients developing Tracheobronchitis or Pneumonia have distinctive complement system gene expression signatures

Project description:The onset of an infection-specific transcriptional program precedes the clinical diagnosis in patients who developed Ventilator-associated pneumonia (VAP). Ventilator-associated tracheobronchitis (VAT) is another respiratory infection affecting outcomes in intubated patients, but interactions between VAT and VAP remains unknown.
