Gene expression in DN4 thymocytes from mice with an inducible deletion of Ikaros

ABSTRACT: The aim of the experiment was to visualize genes under the control of Ikaros during early T cell development. We used mice carrying floxed Ikaros alleles that were crossed with the Rosa26-CreERT2 mice, and which were injected with tamoxifen for 4 days. DN4 thymocytes were sorted from 4 mice (5-6 week-old) which are positive or not for the Rosa26-CreERT2 transgene. DN4 cells were sorted from 2 Ikf/f Rosa26-CreERT2+ mice and 2 Ikf/f mice, which were all treated with tamoxifen for 4 days. Loss of Ikaros was confirmed in sorted cells from the Ikf/f Rosa26-CreERT2+ mice by western blot. Gene expression profiles were determined on total RNA from sorted cells with Affymetrix Mouse Gene arrays.

Splenic B1 and B2 cells from mice with induced deletion of Ikaros

Project description:The experiment aimed at determining the genes that are under the control of the Ikaros transcription factor in mouse splenic B1 and B2 B lymphocyte subsets. To this aim, we used Ikf/f R26-CreERT2+ (Cre+) or Ikf/f R26-CreERT2- (Cre-) mice, which correspond to mice with floxed null alleles for Ikzf1 (Heizmann et al., JEM 210:2823-32, 2013) that were crossed with the R26-CreERT2 mice, which harbor a knock-in of the cDNA encoding the tamoxifen (TAM) inducible CreERT2 recombinase in the Rosa26 gene (Badea et al, J. Neurosci 23:2314-22, 2003). 6-8 week-old mice were injected daily with TAM for 3d (50mg/kg). Mice were sacrificed 10d after the first injection, and splenic B1 and B2 B cell populations sorted by flow cytometry. Splenic B1 and B2 cells from mice with induced deletion of Ikaros

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 tendons from mice with a targeted deletion of scleraxis

Project description:We report RNA sequencing data from the plantaris 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 (Scx-). Mice in which scleraxis was deleted were created by crossing scleraxis-floxed mice with Rosa26-CreERT2 mice. Rosa26-CreERT2 mice that did not have a floxed scleraxis allele served as controls. Mice were treated with tamoxifen for 5 days to induce recombination at the scleraxis locus, and then subjected to a synergist ablation procedure in which the Achilles tendon is removed, resulting in compensatory growth of the plantaris tendon. Mice were analyzed either 7 or 14 days after synergist ablation. Control mice that did not undergo tamoxifen treatment or synergist ablation were also studied (NOC).

Single-cell RNAseq of murine Bcl6-deficient ILC against wild-type controls

Project description:Innate lymphoid cells (ILC) are tissue-resident effector cells with important roles in tissue homeostasis, protective immunity and inflammatory disease. Here we investigated the role of the transcription factor Bcl6 in small intestinal innate lymphoid cells. Specifically, we performed single-cell RNA-seq on total small intestine lamina propria ILCs from tamoxifen-treated Id2-CreERT2 ROSA26-tdRFP Bcl6-fl/fl mice and Id2-CreERT2 ROSA26-tdRFP controls.

Project description:This study examined the effect of mutant PIK3CAH1047R expression in mammary subsets of preneoplastic mammary glands from Lgr5-creERT2/PIK3CA H1047R mice Mammary cell subpopulations were isolated from Lgr5-creERT2/PIK3CA H1047R and Lgr5-creERT2 control animals 4 weeks after activation of PIK3CA H1047R transgene expression by Tamoxifen injection. Pooled mammary glands of 2-3 estrus-synchronized mice per genotype were sorted in 3 independent sortings and used for microarray analysis (24 samples in total).
