Project description:PTIP (Pax2 transactivation domain-interacting protein) is a nuclear protein containing six BRCT domains. It has been shown that PTIP affects gene expression by controlling the activity of the transcription factor Pax2 and histone H3 lysine 4 methyltransferase complexes. In addition to its role in transcriptional regulation, PTIP has been implicated in DNA damage response. To ask if the depletion of PTIP affects the expression level of genes encoding DNA damage response factors , we compared the whole transcripts between wild-type and PTIP deficient chicken DT40 B cell lines. The total RNAs were isolated from wild-type and PTIP deficient cells (PTIP-/-/-) using Sepasol®-RNA I (Nacalai tesque, Japan). The gene expression profiles were examined using Genechip® Chicken Genome Array (Affymetrix Cat #900590), by GeneticLab co. Ltd. Japan, following Genechip® protocol.

Project description:Transcription profiling of chicken Pax5 deficient DT40 B cell line to investigate the targets of Pax5 which is required for B-cell differentiation Used in cross-species comparison to investigate evolutionarily conserved regulatory circuits in B cell development Pax5 deficient DT40 B cells (3 biological replicates) were compared to DT40 wild-type cells (3 biological replicates).

Project description:The aim of experiment was to study on genome-wide level IRF4 target genes in chicken DT40 B cell line, by comparizon of gene expression profiles of IRF4-deficient DT40 cells with WT IRF4 DT40 cells .
Project description:Glomerular RNA comparison between wild-type and podocyte specific deletion of the PTIP gene in 1 month old kidneys. The PTIP gene was deleted using a floxed allele and a Podocin-Cre driver strain. These mice develop protein urea by 3 months of age. This study was designed to find gene expression differences prior to the onset of the phenotype.

The PTIP gene was deleted using a floxed allele and a Podocin-Cre driver strain. These mice develop protein urea by 3 months of age. This study was designed to find gene expression differences prior to the onset of the phenotype. A ptip floxed allele was crossed into the Podocin-Cre expressing strain to generate ptip fl/fl homozygous mice or ptip fl/- transheterozygous mice with or without the Cre expressing transgene. Animals were genotyped and assigend into two groups: Mutants with PTIP deletion (PTIP-) with the genotype ptip fl/fl:Pod-Cre or ptip fl/-:Pod-Cre or control mice (PTIP+) with either ptip fl/fl or ptip fl/-. Note that the floxed allele produced normal levels of wild-type PTIP protein. Kidneys were excised at 1 month of age. Glomeruli enriched fractions were generated by sieving of the tissue homogenates. RNA was prepared from glomerular enriched fractions.
