The transcriptional repressor Blimp1/Prdm1 regulates post-natal reprogramming of intestinal enterocytes

ABSTRACT: Expression profiling of Prdm1 mutant E18.5 small intestine was performed using Illumina whole genome V2 arrays. The hypothesis tested in the present study was that Blimp1 regulates the transcription of key genes involved in enterocyte differentiation and survival. Results identify substantial and premature activation of key components of the adult enterocyte biochemical signature.

The transcriptional repressor Blimp1/Prdm1 regulates post-natal reprogramming of intestinal enterocytes

Project description:Expression profiling of Prdm1 mutant E18.5 small intestine was performed using Illumina whole genome V2 arrays. The hypothesis tested in the present study was that Blimp1 regulates the transcription of key genes involved in enterocyte differentiation and survival. Results identify substantial and premature activation of key components of the adult enterocyte biochemical signature. Villin-Cre and Prdm1BEH/+ animals were intercrossed to generate heterozygous Villin-Cre, Prdm1BEH males that were then mated with homozygous Prdm1 CA/CA females carrying the R26R allele to generate Prdm1+/+ (Prdm1CA/+) or Prdm1-/- (Villin-Cre, Prdm1CA/BEH) offspring. Total RNA obtained from 11 Prdm1+/+ and 10 Prdm1-/- E18.5 small intestine samples was hybridized to Illumina WG6_V2 beadchips.

Blimp1/Prdm1 governs terminal differentiation of endovascular trophoblast giant cells and defines multipotent progenitors in the developing placenta

Project description:Expression profiling of Prdm1 mutant E9.5 placenta was performed using Illumina whole genome V2 arrays. The hypothesis tested in the present study was that Blimp1 regulates the transcription of key genes involved in trophoblast differentiation. We demonstrate that the invading SpA-TGCs display robust Blimp1 expression and Blimp1 functional loss selectively disrupts specification of this discrete TGC sub-type. Transcriptional profiling experiments identified additional SpA-TGC lineage restricted marker genes that potentially regulate placental morphogenesis. Prdm1BEH/+ (Vincent et al., 2005) animals were intercrossed to generate null placental tissue. Total RNA obtained from 10 Prdm1+/+ and 11 Prdm1-/- E9.5 placenta samples was hybridized to Illumina WG6_V2 beadchips.

Molecular function of Prdm1/Blimp1 in trophoblast giant cell differentiation.

Project description:Expression profiling of wild-type and Prdm1 null mouse trophoblast giant cell cultures using Illumina whole genome mouse V2 arrays. The hypothesis tested was that Prdm1/Blimp1 regulates expression of genes required for spiral artery trophoblast giant cell function. Prdm1 null and littermate control wild-type trophoblast stem cell clones were generated from blastocyst outgrowths. Total RNA was obtained from multiple replicates of four wild-type TS cell clones and four Prdm1 null TS cell clones differenitated for zero, two, four and six days by growth factor withdrawal and hybridized to Illumina WG6_V2 arrays

Analysis of Blimp-1 and Irf-1 genomic binding in wild type and Prdm1/Blimp-1 mutant embryonic gut

Project description:The goal of this study was to profile Blimp1 binding in E18.5 small intestine using a Blimp-1-eGFP knock-in allele, and to compare Blimp-1-eGFP genomic binding with Irf-1 genomic binding in normal small intestine. Changes in Irf-1 binding between wild type and Prdm1/Blimp-1 mutant small intestine were also assessed. ChIP-seq was performed for Blimp-1-eGFP in duplicate in E18.5 small intestine expressing the fusion protein using anti-GFP antibody. As a negative control a single anti-GFP ChIP was also performed in wild type small intestine. ChIP-seq for Irf-1 was performed in duplicate in both wild type and Prdm1/Blimp-1 mutant E18.5 small intestine using an anti-Irf-1 antibody. Duplicate IgG ChIP control in wild types was performed as a negative control. All samples had an associated input chromatin sample sequenced.
