The transcriptional repressor Blimp-1/Prdm1 controls the maternal decidual response during pregnancy [ChIP-seq]

ABSTRACT: To identify candidate Blimp1 target genes in maternal decidua we performed GFP antibody ChIP-seq analysis of E6.5 decidua from homozygous female EGFP-BLIMP1 mice that express an endogenous N-terminal EGFP-tagged Blimp1 protein (Mitani et al., 2017).

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

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.

The transcriptional repressor Blimp1/PRDM1 regulates the maternal decidual response in mice.

Project description:The transcriptional repressor Blimp1 controls cell fate decisions in the developing embryo and adult tissues. Here we describe Blimp1 expression and functional requirements within maternal uterine tissues during pregnancy. Expression is robustly up-regulated at early post-implantation stages in the primary decidual zone (PDZ) surrounding the embryo. Conditional inactivation results in defective formation of the PDZ barrier and abnormal trophectoderm invasion. RNA-Seq analysis demonstrates down-regulated expression of genes involved in cell adhesion and markers of decidualisation. In contrast, genes controlling immune responses including IFNγ are up-regulated. ChIP-Seq experiments identify candidate targets unique to the decidua as well as those shared across diverse cell types including a highly conserved peak at the Csf-1 gene promoter. Interestingly Blimp1 inactivation results in up-regulated Csf1 expression and macrophage recruitment into maternal decidual tissues. These results identify Blimp1 as a critical regulator of tissue remodelling and maternal tolerance during early stages of pregnancy.

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.
