Small Nucleolar RNAs in the Dlk1-Gtl2 Imprinting Locus Maintains LT-HSC Self-renewal by Regulation of rRNA Modification and Translation [ncRNA-Seq]

Project description:Small nucleolar RNA (snoRNA) are non-coding RNAs, which participate in the chemical modification of ribosomal RNAs (rRNAs) and small nuclear RNAs. However, the roles of snoRNA in homeostasis of hematopoietic stem cells(HSCs) have not been studied. We isolated four hematopoietic stem and progenitor cells (HSPCs) (LT-HSCs, IT-HSCs, ST-HSCs, and MPPs) from the bone marrow (BM) of C57BL/6 mice and performed small RNA-seq. We found SnoRNAs belonging to SNORD113-114 cluster were specifically enriched in LT-HSCs, and their expression decreased dramatically with HSC differentiation. Here, we used a modified small RNA-seq method to examine snoRNA profiles of hematopoietic progenitor and mature cells in WT mice.

Here, we used a modified small RNA-seq method to examine snoRNA profile in KO mice.

IMP1 re-expression in adult hematopoietic stem cells RNA Sequencing

Project description:The onco-fetal RNA-binding protein IMP1 is expressed in fetal liver HSCs, but down-regulated in adult BM HSCs. We here show that when IMP1 is re-expressed in adult HSCs it induces a significant part of the fetal HSC gene expression signature. In addition, IMP1 re-expression leads to the expansion of phenotypic long term (LT-)HSCs, and increased generation of fetal peritoneal B1a B-cells and thymic γδ-T-cells. Finally, IMP1 expressing adult LT-HSCs show dramatically improved self-renewal in serial transplantations compared to their normal counterparts. To assess the effect of IMP1 re-expression on the molecular properties of adult HSCs we performed RNA sequencing of total RNA isolated from Control and IMP1 HSCs sorted from primary recipient mice, transplanted with control or IMP1+ total bone marrow cells.

RNA-sequencing analysis of adult mouse wild type (Prdm16-Mx1-Cko/Cko; +/+) and Prdm16-/- (Prdm16-Mx1-Cko/Cko; Tg/+) Long Term-Hematopoietic Stem Cells (LT-HSC).

Project description:Regulation of quiescence is critical for the maintenance of adult hematopoietic stem cells (HSCs). Previous studies by gene disruption during mouse embryonic development have shown that transcription factor gene Prdm16 is important for the generation/maintenance of fetal liver HSCs; however, the underlying mechanisms and the function of Prdm16 in adult HSCs remain unclear. To investigate the role of Prdm16 in adult HSCs, we generated a novel conditional knockout mouse model and deleted Prdm16 in adult mouse hematopoietic system using the interferon inducible Mx1-Cre. Our results show that deletion of Prdm16 leads to a gradual decline of adult HSC numbers and a concomitant increase in the multipotent progenitor (MPP) compartment. Prdm16 deletion in the hematopoietic system following transplantation produced the same phenotype indicating that the defect is intrinsic to the HSCs. This HSC loss was also exacerbated by stress induced by 5-FU injections. Annexin V staining showed no difference in apoptosis between wild type and knockout HSCs. In contrast, BrdU analysis revealed that loss of Prdm16 significantly increases cycling of long-term HSCs (LT-HSCs) with majority of the cells found in the S to G2/M phase. Consistently, RNA-seq analysis of mouse LT- HSCs with and without Prdm16 deletion showed that Prdm16 loss induced a significant decrease in the expression of several known cell cycle regulators of HSCs, among which Cdkn1a and Egr1 were further identified as direct targets of Prdm16. Our results suggest that Prdm16 preserves the function of adult LT-HSCs by promoting their quiescence.
