Project description:We have created the Ts66Yah a new model for Down syndrome or T21, derived from the Ts65Dn. Ts66Yah does not contain a set of genes present in 3 copies that are not linked to T21. On this model (Ts66), we performed an RNA seq analysis on 2 structures (hippocampus and entorhinal cortex, ref: S18276) and we have done the same experiment on the Ts65Dn line to compare the 2 models. For this we sampled the hippocampus (hippo) and the entorhinal cortex (EntCortex) from 6 wild-type control male littermate animals and 6 males trisomic individual (Ts66 or Ts65).

Project description:Patterns of gene expression in the aged entorhinal cortex and hippocampus were examined one month after entorhinal administration of BDNF lentivirus. Whole-genome patterns of expression were examined using Affymetrix arrays four weeks after entorhinal injection of lentiviral-BDNF or GFP injection compared to control subjects. Experiment Overall Design: 27 Samples total: 4 biological replicates of Age rats BDNF treated, 3 biological replicates of Age rats eGFP treated, and 4 biological replicates each of Aged and Young rats controls for the Entorhinal cortex tissue. 2 biological replicates of Age rats BDNF treated, 2 biological replicates of Age rats eGFP treated, and 4 biological replicates each of Age and Young rats controls for the hippocampus tissue.

Project description:Trisomy 21 (T21) is the most frequent genetic cause of cognitive impairment. To assess the perturbations of gene expression in T21, and to eliminate the noise of the genomic variability, we studied the transcriptome of fetal fibroblasts from a pair of monozygotic twins discordant for T21. Here we show that the differential expression between the twins is organized in domains along all chromosomes that are either up- or downregulated. These gene expression dysregulation domains (GEDDs) can be defined by the expression level of their gene content, and are well conserved in induced pluripotent stem cells derived from the twinsM-bM-^@M-^Y fibroblasts. Comparison of the transcriptome of the Ts65Dn mouse model of DS and wild-type, also showed GEDDs along the mouse chromosomes that were syntenic in human. The GEDDs correlate with the lamina-associated (LADs) and replication domains of mammalian cells. The overall LADs position was not altered in trisomic cells. However, the H3K4me3 profile of the trisomic fibroblasts was modified and accurately followed the GEDD pattern. These results suggest that the nuclear compartments of trisomic cells undergo modifications of the chromatin environment influencing the overall transcriptome and that GEDDs may therefore contribute to some T21 phenotypes. mRNA-Seq profiling in Down syndrome: fibroblasts derived from a pair of monozygotic twins discordant for trisomy 21 (4 replicates), iPS cells from the same pair of discordant twins, fibroblasts from a pair of normal monozygotic twins, fibroblasts from 16 unrelated individuals (8 trisomic and 8 euploid controls), fibroblasts from the Ts65Dn mouse model of Down syndrome (1 trisomic mouse and 1 control wt).
