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

ABSTRACT: 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

Protein Arginine Methyltransferase 1 is Essential for the Meiosis of Male Germ Cells

Project description:Methods: Prmt1 floxed mice were crossed with Rip2-Cre and Pdx1-CreERT2 mice to generate Prmt1 KO and Prmt1 iKO mice. R26-eYFP mice were crossed for lineage tracing experiments and cell sorting. All mice were backcrossed and maintained on a C57BL/6J background. Cre recombination for CreERT2 was induced by total 5 times intraperitoneal injections (75 mg/kg) of corn oil dissolved tamoxifen (T5648, Sigma-Aldrich) over 2 weeks.

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

Project description: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.

Comprehensive proteometics identifies FBXL6 substrates involved in liver cancer

Project description:FBXL6 is frequently over-expressed in human hepatocellular carcinoma (HCC). However, it is still unknown the underlying mechanisms by which FBXL6 promotes HCC. In this study, we compared ubiquitinated protein profiles among a panel of liver tissue samples (including HCC, adjacent tissues and normal tissues) from Fbxl6LSL-fl/+; Alb-cre mice and Alb-cre mice by proteomics and ubiquitomics analysis. There are many proteins with ubiquitination in FBXL6 overexpressed HCC, suggesting ubiquitination may play a critical role in FBXL6-mediated HCC.

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.

Regional specialization and fate specification of mesenchymal stromal cells in skeletal development [scRNA-seq]

Project description:To identify cellular heterogeneity and molecular signatures of bone marrow stromal (BMSCs) cells, we performed scRNA-seq of non-hematopoietic stromal cells from 3-week-old mice. In addition, to gain further insight into MSC differentiation in vivo, Pdgfrb-CreERT2 Rosa26-mTmG (Pdgfrb-Cre R26-mT/mG) double transgenic mice were treated with tamoxifen at P1-3 and sacrificed at P21 for the isolation of GFP+ cells from long bone followed by scRNA-seq analysis.

The catalytic domain of the histone methyltransferase NSD2/MMSET is required for the generation of B1 cells in mice

Project description:Humoral immunity in mammals relies on the function of two developmentally and functionally distinct B cell subsets - B1 and B2 cells. While B2 cells are responsible for the adaptive response to environmental antigens, B1 cells regulate the production of polyreactive and low affinity antibodies for innate humoral immunity. The molecular mechanism of B cell specification into different subsets is understudied. We identified lysine methyltransferase NSD2 (MMSET/WHSC1) as a critical regulator of B1 cell development. In contrast to its minor impact on B2 cells, deletion of the catalytic domain of NSD2 in primary B cells impairs the generation of B1 lineage. Thus, NSD2, a histone H3 K36 dimethylase, is the first-in-class epigenetic regulator of a B cell lineage in mice.

Mouse CD4+/CD8+ thymocytes from miR-181a1/b1 KO vs WT

Project description:miR-181a1/b1, miR-181a2/b2, and miR-181c/d belong to a highly conserved family of microRNA clusters, yet their role in vivo is poorly understood. Here we show that the miR-181a1/b1 cluster is absolutely essential for NKT development and is a critical determinant of thymocyte proliferation, survival and T-cell receptor Î± locus rearrangement. Furthermore, while individual ablation of miR-181a2/b2 and miR-181c/d revealed no overt phenotypes, compound mutant mice lacking both miR-181a1/b1 and miR-181a2/b2 display decreased survival, reduced body weight, and abnormal B cell development. Mechanistically, we reveal that miR-181 regulates PTEN, a key tumor suppressor whose abundance determines key metabolic adaptations required to meet the biosynthetic demands of highly proliferative tissues. These results provide important insights into the physiological function of this family of microRNAs in vivo; moreover, it places miR-181 as a central regulator of the PI3K signaling pathway and cellular metabolism. Three sorted populations of double positive (DP) thymocytes from each of two conditions (WT and miR181a1/b1 -/- mice)
