FOXP1 inhibits cell growth and attenuates tumorigenicity of neuroblastoma

Project description:Single-color gene expression profiles from 3 neuroblastoma cell lines were generated using 44K oligonucleotide microarrays. To gain insights into the molecular processes occurring upon FOXP1 re-expression, we performed series of time-resolved gene expression measurements in FOXP1 and GFP transgenic neuroblastoma cell lines. Single-color gene expression profiles from 3 neuroblastoma cell lines were generated using 44K oligonucleotide microarrays. Total RNA of FOXP1- and GFP-expressing IMR-32, CHP-212 and SK-N-BE(2) cells was isolated at 0, 12, 24 and 72 h using Trizol. To determine global differences in the expression profiles of FOXP1- and GFP-induced IMR-32, CHP-212 and SK-N-BE(2) cells, mean expression levels of each gene between FOXP1-induced and control (GFP) cells were compared.

Hox-C9 activates the intrinsic pathway of apoptosis and is associated with spontaneous regression in neuroblastoma [cell line_genex_44k]

Project description:Single-color gene expression profiles from 2 neuroblastoma cell lines were generated using 44K oligonucleotide microarrays. To gain insights into the molecular processes occurring upon HOXC9 re-expression, we analyzed gene expression profiles of IMR-32 and SK-N-AS cells after Hox-C9 induction using microarrays. We used gene ontology (GO) annotations to find classes of genes that are significantly over-represented in gene sets that were either up- or downregulated after HOXC9 re-expression. One-color gene expression analysis Single-color gene expression profiles from 2 neuroblastoma cell lines were generated using 44K oligonucleotide microarrays. Total RNA of HOXC9- and GFP-expressing SK-N-AS and IMR-32 cells was isolated at 0, 6, 12, 24, 48 and 96 h using Trizol. To determine global differences in the expression profiles of HOXC9- and GFP-induced SK-N-AS and IMR-32 cells, mean expression levels of each gene between HOXC9-induced and control (GFP) cells were compared. Gene Ontology Tree Machine (GOTM) was used to identify functional categories associated with the condition of the respective cell line.

MJAY analysis of vestibular macula RNA obtained from Bronx waltzer and control mice.

Project description:The spontaneous mutant Bronx waltzer (bv) mouse line is characterized by deafness and balance defect. We located the bv mutation to the Srrm4 gene which encodes a regulator of alternative pre-mRNA splicing. We found that Srrm4 is expressed in balance and hearing organs (i.e. in the vestibular maculas and the cochlea). Srrm4 is also expressed in the central nervous system including the cerebellum. To identify potential splicing defects in bv/bv mice, we analyzed RNA samples from the vestibular maculas and cerebellums of bv/bv mice and control (bv/+) littermates, using mouse exon junction microarrays (MJAY). In this dataset, we include probe-set level data obtained from vestibular macula samples. The processed data represent probe-set intensities that have been normalized to gene expression levels (Inorm). Inorm was calculated using batch-corrected data as well as data that were not corrected for a batch effect. 7 total samples were analyzed: vestibular maculas from 4 heterozygous (bv/+) and 3 homozygous (bv/bv) mouse embryos at E16.5.

Brain heterotopia formation by ciliopathic breakdown of neuroepithelial and blood-cerebrospinal fluid barriers

Project description:In this study, we found that ablation of genes encoding ciliary transport proteins such as intraflagellar transport homolog 88 (Ift88) and kinesin family member 3a (Kif3a) in cortical radial progenitors led to periventricular heterotopia during late mouse embryogenesis. Conditional mutation of primary cilia unexpectedly caused breakdown of both the neuroepithelial lining and the blood-choroid plexus barrier. Choroidal leakage was partially caused by enlargement of the choroid plexus in the cilia mutants. We found that the choroid plexus expressed platelet-derived growth factor A (Pdgf-A) and that Pdgf-A expression was ectopically increased in cilia-mutant embryos. Cortices obtained from embryos in utero electroporated with Pdgfa mimicked periventricular heterotopic nodules of the cilia mutant.

A strand-specific switch in noncoding transcription switches the function of a Polycomb/Trithorax response element

Project description:Polycomb/Trithorax response elements (PRE/TREs) can switch their function reversibly between silencing and activation, by mechanisms that are poorly understood. Here we show that a switch in forward and reverse noncoding transcription from the Drosophila vestigial (vg) PRE/TRE switches the status of the element between silencing (induced by the forward strand) and activation (induced by the reverse strand). In vitro, both ncRNAs inhibit PRC2 histone methyltransferase activity, but in vivo only the reverse strand binds PRC2. Overexpression of the reverse strand evicts PRC2 from chromatin and inhibits its enzymatic activity. We propose that interactions of RNAs with PRC2 are differentially regulated in vivo, allowing regulated inhibition of local PRC2 activity. Genome-wide analysis shows that strand switching of ncRNAs occurs at several hundred PcG binding sites in fly and vertebrate genomes. This work identifies a novel and potentially widespread class of PRE/TREs that switch function by switching the direction of ncRNA transcription. E(Z) and H3K27me3 profile in Drosophila embryos of two transgenic lines (pKC27.vg.fwd' and pKC27.vg.rev') that were crossed to daGAL4 in order to overexpress the forward or the reverse vg PRE/TRE ncRNA from an ectopic site ('site 1' in this study).

Analysis of embryonic day E14.5 and E16.5 mouse ureters from Tshz3LacZ/LacZ mutants and wild types

Project description:In the urinary tract, smooth muscle (SM) is present in the renal pelvis, the ureter, the bladder and the urethra and plays a crucial role in the functional and structural integrity of these organs. In Tshz3 mutant ureters the myogenic program is not activated in the proximal region due to the absence of expression of myocardin (Myocd), a key regulator of SM differentiation. We set out to characterize TSHZ3-dependent mechanisms that participate to the process of ureteric smooth muscle cells (SMC) differentiation. To this aim, we used microarrays to identify distinct classes of up- and down-regulated genes in Tshz3LAcZ/LacZ mutant ureters at two different time points; at E14.5, which corresponds to the onset of the myogenic program and at E16.5, when SMC express the full repertoire of differentiation marker genes. Mouse embryonic (E14.5 and E16.5) wild type and Tshz3LacZ/LacZ mutant ureters were dissected for RNA extraction and hybridization on Affymetrix microarrays.
