Project description:Background and Objective: Currently, the cells for transplantation were derived from either autologous or allogeneic tissue. The former has a drawback that the quality of donor cells could depend on the patient’s condition, and the quantity could also be limited. To solve these problems, we investigated the potential of allogeneic cardiac mesenchymal progenitors (CMPs) derived from postmortem heart, which might be an immunological privileged like bone marrow-derived mesenchymal progenitors. Materials and Methods: We examined whether viable CMPs could be isolated from murine postmortem cardiac tissue that was harvested 24 hours postmortem. After two to three weeks propagation with high dose of basic fibroblast growth factor, we performed the cellular characteristics analyses, which included proliferation and differentiation property flow cytometric analyses, and microarray analyses. Results: Postmortem CMPs had longer lag phase after seeding than CMPs from living tissues, but they demonstrated the similar characteristics in all above examinations. In addition, global gene expression analysis by microarray indicated the similar characteristics between the cell derived from postmortem and living tissue. Conclusion: These results indicate allogeneic postmortem CMPs could have promising potential for cell transplantation as clinical applications, because of circumventing the issue of brain death. The samples were collected fom living or postmortem cardiac tissue (24 hr at 4C). We generated cardiac mesenchymal progenitors (CMPs) from these cardiac tissue, and compared global gene expression by AgilentMouse GE 8x60k Microarray. Adult, or fetal mouse heart RNAs were used as positive control. Adult mouse total heart RNAs were purchased from Clontech. Fetal mouse heart was extracted from fetus which is embryonic day 16.5 C57BL/6 strain. Tg means Transgenic mouse (C57BL/6-Tg(Myh6-EGFP)MG2).

Project description:This SuperSeries is composed of the following subset Series:; GSE5388: Adult postmortem brain tissue (dorsolateral prefrontal cortex) in subjects with bipolar disorder; GSE5389: Adult postmortem brain tissue (ortibtofrontal cortex) in subjects with bipolar disorder; Bipolar affective disorder is a severe psychiatric disorder with a strong genetic component but unknown pathophysiology. We used microarray technology (Affymetrix HG-U133A GeneChips) to determine the expression of approximately 22 000 mRNA transcripts in post-mortem brain tissue (dorsolateral prefrontal cortex and orbitofrontal cortex) from patients with bipolar disorder and matched healthy controls. Experiment Overall Design: Refer to individual Series

Project description:Down syndrome (DS) is the result of trisomy chromosome 21 but the mechanisms by which the genotype leads to the characteristic disease phenotype are unclear. We performed a microarray study using human adult brain tissue (dorsolateral prefrontal cortex) from DS subjects and healthy controls to characterise for the first time the human adult Down syndrome brain Experiment Overall Design: RNA extracted from human postmortem brain tissue from adult subjects with Down syndrome and healthy controls was hybridised to Affymetrix HG-U133A GeneChips to identify differentially expressed genes in the disease state.

Project description:Comparison between in vitro transcription- and cDNA-mediated annealing, selection and ligation (DASL)-based assays on brain-specific reference RNA, and postmortem frozen and formalin fixed brain tissue from autistic and control cases. Investigation of data preprocessing techniques for DASL-assayed RNA samples from frozen brain tissue. IVT- and DASL-based expression assays were performed on 10 reference RNA samples (brain and pooled artificially degraded at 0, 10, 30, and 60 min), 4 formalin-fixed tissue-extracted RNA samples with replicates, and 57 frozen tissue-extracted RNA samples with replicates. A subset of the 57 (N=33 samples) from frozen brain tissue assayed using the DASL-based platform were then used to test different dataset preprocessing strategies implemented in the lumi package in R/Bioconductor. The data from frozen-tissue extracted DASL-processed RNA samples passing exclusion criteria were log2 transformed and normalized using quantile normalisation with lumi in R (quantile-normalized data available as a supplementary file linked to the Series record).

Project description:Analysis of cocaine use disorder (CUD) associated epigenome-wide DNA methylation (DNAm) alterations in human postmortem brain tissue of Brodmann Area 9. Tissue samples from N=21 CUD cases and N=21 individuals without CUD originating from the Douglas Bell Canada Brain Bank (DBCBB) were included. Epigenome-wide DNAm was investigated using the Illumina Infinium MethylationEPIC array.
