RNA-seq expression profiling of Suz12-deleted or wild-type organoids derived from basal or luminal mouse mammary epithelial cells.

ABSTRACT: Total RNA was extracted from organoids grown from single sorted luminal or basal populations from the mammary glands of Rosa26-creERT2 Suz12 flox female mice. Cultures were treated with 4-hydroxytamoxifen to induce deletion of Suz12.

ORGANISM(S): Mus musculus

Impact of IRP deficiency on the proteome of Ly6G+ cells from the bone marrow in mice

Project description:The overall objective of the project is to evaluate the effects of loss of function of iron regulatory proteins (IRP1, encoded by Aco1)-1 and -2 (IRP2, encoded by Ireb2) during adult life. Mice carrying floxed Aco1 and Ireb2 alleles were crossed to a knockin strain expressing a tamoxifen-inducible CRE recombinase under the control of the Rosa26 promoter. The resulting Aco1flox/flox,Ireb2flox/flox,Rosa26+/CreERT2 mice are designated P1/2-KO; littermates lacking the CreER sequence (Aco1flox/flox,Ireb2flox/flox,Rosa26+/+) serve as reference and are designated P1/2-CTR. Adult mice were injected (i.p.) with tamoxifen on day 1 and day 3 to ablate the IRPs in the whole body, and were sacrificed on day 10 for analysis. Bone marrow cells were collected and LY6G+ cells were magnetically sorted for proteome analysis by LC-MS/MS using an Ultimate 3000 UPLC system connected to an Orbitrap Exploris 480 mass spectrometer.

Transcriptional analysis of tenocytes from mice with a targeted deletion of scleraxis

Project description:We report RNA sequencing data from tenocytes cultured from the tail tendons of adult male mice in the C57Bl/6 background that either have the scleraxis gene (Scx+) or mice in which scleraxis has been deleted using CreERT2 driven from the Rosa26 locus using 4-hydroxytamoxifen (4HT).

Expression profile of castration-resistant LY6D+ luminal progenitors during prostate tumourigenesis

Project description:By using luminal lineage tracing model, here we report the regulatory network underlying intrinsically castration-resistant LY6D+ luminal progenitors during prostate tumourigenesis. The luminal cell-specific PTEN deficient mouse model of PCa (K8-CreERT2;PtenFlox/Flox;R26-StopFlox/Flox-EYFP (K8PY) and the control K8-CreERT2;R26-StopFlox/Flox-EYFP (K8Y) mice) are used in this study.

SUZ12 immunoprecipitation followed by PRM of SUZ12 peptides to identify alternatively spliced isoforms of SUZ12 at the protein level.

Project description:Alternative splicing of SUZ12 exon 4 is predicted to generate two alternative isoforms differing by the inclusion or exclusion of 69 nucleotides in exon 4, which we named SUZ12-long (SUZ12-L) and SUZ12-short (SUZ12-S) respectively. At the protein level SUZ12 exon 4 encodes 23 amino acids (aa 129–152 in SUZ12-L) that partially overlap with the WD-binding domain 1 (WDB1, 110–145). To detect the existance of SUZ12-S at the protein levels we performed SUZ12 immunoprecipitation coupled with mass spectrometry (IP-MS) in the WT and ∆ex4 clones to identify SUZ12-S unique peptides. We identified a SUZ12-S specific peptide in both WT #2 and ∆ex4 #1. These observations were confirmed by SUZ12 IP followed by Western blot (WB) (size shift).

SUZ12 immunoprecipitation followed by protein indentification via mass spectrometry (SUZ12 IP-MS) in mESCs of SUZ12 WT, delta exon 4, KO, and KO rescues with SUZ12-L and SUZ12-S

Project description:Suz12 exon 4 encodes 23 amino acids (aa 129–152 in SUZ12-L) that partially overlap with the WD-binding domain 1 (WDB1, 110–145). We reasoned that exon 4 skipping might alter the structure of SUZ12 and, possibly, PRC2 composition. To explore this possibility, we generated ESCs that lack the Suz12 exon 4 via CRISPR-Cas9–induced deletion. In addition, to rule out any biases due to the expression levels and/or SUZ12 epitope masking, we generated Suz12 knockout (KO) ESCs (herein, KO) in which Suz12 expression was subsequently rescued by re-introducing either the Suz12-L or Suz12-S mouse isoform fused to a triple-Flag tag under the regulation of a CAG promoter (KO+L/S; Figures S2H–S2K). We performed SUZ12 immunoprecipitation coupled with mass spectrometry (IP-MS) in the WT and ∆ex4 clones to compare their interactomes and with a flag antibody in the KO and rescue cell lines. As expected, no peptides corresponding to exon 4 were retrieved in ∆ex4 samples, while the rest of the sequence displayed similar coverage. Comparison of interactors in the two conditions revealed that SUZ12 binding to AEBP2 and JARID2 was strongly reduced in ∆ex4 cells with respect to WT cells, whereas SUZ12 binding to most core components or to PRC2.1-specific factors was unchanged or only slightly increased . These observations were confirmed by SUZ12 IP followed by Western blot (WB). Flag IP-MS in rescue cells confirmed that, while the long isoform was able to correctly form comparable amounts of both PRC2.1 and PRC2.2 subtypes, interaction of the SUZ12-S with PRC2.2-specific factors was drastically reduced.

RNA-Seq of murine GIST-like tumors after Etv1 ablation

Project description:We used a mouse expressing three alleles 1) KitV558Delta/+ activating allele that develop GIST-like tumors in the cecum, 2) Etv1 flox/flox conditional knockout allele and 3) Rosa26-CreERT2 tamoxifen activated Cre allele. Mice were treated with either Tamoxifen (to delete Etv1) or corn oil (control). Cecal tumors were isolated for gene expression profiling by RNA-Seq.

Transcriptomic changes in Sin3A deficient CD4 T cells

Project description:Highly purified CD4+ T cells from Rosa26-CreERT2 +/- Sin3AF/F micewere then cultured in interleukin 7 (IL-7) in the absence or the presence of 4-hydroxytamoxifen (TAM) for 6 days to allow Cre expression in the absence of cell division or differentiation . Next, we compared the behavior of Sin3A sufficient and deficient T cells in Th17 skewing conditions. RNA was then isolated and sequenced for the analysis of differential expression of mRNA transcripts
