Project description:Investigation of whole genome gene expression level changes in WASH knockout LT-HSCs, compared to the WASH WT strain. To find the reason that causes LT-HSC abnormal. Gene expression profiling using sorted LT-HSC samples from C57/BL6 strain. Total RNA extracted from WASH control (isolated RNA from WT, IRWT) and knockout mice (IRKO) were quantified by the NanoDrop ND-1000 and RNA integrity was assessed by standard denaturing agarose gel electrophoresis.Each chip measures the expression level of 44, 170 genes from Mus Musculus.

Project description:Long-term hematopoietic stem cells (LT-HSC) maintain lifelong hematopoiesis while preserving the stem cell compartment through self-renewal. The human LT-HSC compartment is molecularly and functionally heterogeneous and also varies across ontogeny. Dissecting the molecular basis for this variation is impeded by the absence of immunophenotypic markers to resolve LT-HSC heterogeneity. Here, we identified ATPase plasma membrane Ca2+transporting 1 (ATP2B1/PMCA1) as a novel cell surface marker that is heterogeneously expressed by CD49f+ LT-HSC across ontogeny. ATP2B1 immunophenotypic expression stratified human CD49f+ LT-HSC from fetal liver (FL), neonatal cord blood (CB) and adult mobilized peripheral blood (mPB) sources into functionally distinct subpopulations in single-cell (sc) clonogenic assays. CD49f+ATP2B1+ LT-HSC exhibited superior long-term repopulation and self-renewal capacities in vivo compared to CD49f+ATP2B1– LT-HSC. Molecular profiling by scMultiome and immunofluorescence microscopy point to enrichment of an HSC self-renewal program that includes the TFEB-endolysosomal axis in CD49f+ATP2B1+ LT-HSC. Our study provides a new tool to dissect the heterogeneous molecular programs in LT-HSC across ontogeny.

Project description:The fate options of hematopoietic stem cells (HSCs) include self-renewal, differentiation, migration and apoptosis, but the interaction between intracellular Ca2+ and cytoplasmic chaperon protein in regulating fate options of long term-HSCs (LT-HSC) is unknown. We created a S100A6 conditional knockout mouse model in the hematopoietic system and our studies showed that in S100A6KO, the number of LT-HSCs was significantly reduced and HSCs engrafted poorly. After 5FU challenge, the frequency of S100A6KO HSCs remained significantly low. Our data showed that S100A6 failed to self-renew through Akt pathway in an intracellular calcium (Cai2+)-dependent manner. Expression profiling of S100A6KO obtained from gene signatures revealed that cytosolic calcium level and proteins translocation to mitochondria were decreased. Mitochondrial oxidative phosphorylation was impaired in S100A6KO. Proteomic data indicated Hsp90 protein and chaperonin family were reduced. Our findings demonstrated that S100A6 regulates fate options of HSCs self-renewal through integrating Akt signaling, specifically governing mitochondria metabolic function and protein quality.
