Description
This GEO submission includes RNAseq raw data (fastq) and processed data (using ASpli 1.6.0) from samples obtained in the wild type and the single prefoldin4 and lsm8 mutants in three different environmental conditions as well as in the triple prefoldin2 prefoldin4 prefoldin6 mutant growth in standard conditions. Overall design: 28 biological samples from 10 different conditions and genopypes, including the Col-0 WT in each condition (standard, cold and salt conditions)
Publication Title

Description
Mesenchymal stem cells (MSCs) And osteolineage cells contribute to the hematopoietic stem cell (HSC) Niche in the bone marrow of long bones. However, Their developmental relationships remain unclear. Here we demonstrate that different MSC populations in the developing marrow of long bones have distinct functions. Proliferative mesoderm-derived nestin- MSCs participate in fetal skeletogenesis, And lose MSC activity soon after birth. In contrast, Quiescent neural-crest-derived nestin+ Cells in the same bones preserve MSC activity, But do not generate fetal chondrocytes. Instead, They differentiate into HSC-niche-forming MSCs, Helping to establish the HSC niche by secreting Cxcl12. Perineural migration of these cells to the bone marrow requires the ErbB3 receptor. The neonatal Nestin-GFP+ PDGFR- Cell population also contains Schwann-cell precursors, But does not comprise mature Schwann cells. Thus, In the developing bone marrow HSC-niche-forming MSCs share a common origin with sympathetic peripheral neurons and glial cells, And ontogenically distinct MSCs have non-overlapping functions in endochondrogenesis and HSC niche formation. Overall design: Total RNA was isolated from small numbers of FACS sorted stromal cells, obtained from neonatal Nes-Gfp bone marrow preparations (2 biological replicates). Each independent set of samples was obtained from pooled skeletal elements (long bones and sterna) form multiple littermates.

Knockouts of the O-GlcNAc cycling enzymes in C. elegans are viable and fertile, allowing a global analysis of the impact of GlcNAcylation. Here we compare gene expression in wild type and O-GlcNAc mutants (ogt-1 and oga-1) in synchronized, fed L1 animals.

Description
Estrogens are potential regulators of the hematopoietic stem cell (HSC) niche and have effects on mature hematopoietic cells; however, whether estrogen signaling directly regulates normal and malignant HSC remains unclear. We demonstrate differential expression and specific roles of estrogen receptors (ER) in hematopoietic progenitors. ERa activation in short-term HSC and multipotent progenitors induced apoptosis. In contrast, the selective ER modulator (SERM) tamoxifen induced proliferation of quiescent long-term HSC, altered their self-renewal signature and compromised hematopoietic reconstitution following myelotoxic stress. Treatment with tamoxifen alone abolished hematopoietic progenitor expansion induced by JAK2V617F by restoring normal levels of apoptosis, blocked JAK2V617F-induced myeloproliferative neoplasm in vivo, and sensitized MLL-AF9+ leukemias to chemotherapy. Tamoxifen showed selective effects on mutant cells compared to normal ones, and had only a minor impact on steady-state hematopoiesis in disease-free animals. These results uncover specific regulation of hematopoietic progenitors by estrogens and potential anti-leukemic properties of SERM Overall design: LT-HSCs, ST-HSCs and MPPs sorted from the bone marrow of mice treated with tamoxifen or vehicle (3 biological replicates per group)
