LRP5 and LRP6 are required for maintaining self-renewal and differentiation of hematopoietic stem cells

Project description:The canonical Wnt signaling pathway has been demonstrated as a critical role in the self-renewal, proliferation and differentiation of Hematopoietic Stem Cells (HSCs), but the functions are indeterminacy in adult HSCs since the different experimental systems using gain- or loss- functions mice models. Low-density lipoprotein receptor-related proteins 5 and 6 (LRP5 and LRP6) are important co-receptors in the canonical Wnt/β-catenin pathway. In this study, the knockout mice models were established for adult HSC investagation via conditional ablation of LRP5 and LRP6 in adult hematopoiesis by Vav-Cre Loxp system. We found the HSC numbers were diminished due to the decreased proliferation and cell cycle. To investigate the molecular mechanisms, RNA-seq was performed using HSC cells isolated from WT and dKO mice.

Transcriptome analysis of LRP5- and LRP6-depleted HCC38 cells.

Project description:In order to characterize the differences between the co-receptors LRP5 and LRP6, we have analyzed the transcriptome of HCC38 cells - a triple negative breast cancer cell line - 24, 48 and 72 hours following the depletion of LRP5 or LRP6 using siRNAs.

Transcriptome analysis of Wnt3a-treated Wild Type, Lrp5KO , Lrp6KO and Lrp5/6KO osteoblasts

Project description:Wnt signaling is a major regulator of osteoblast differentiation and function. To investigate how Wnt3a signaling regulates osteoblastic gene expression and to identify the role of Lrp5 and Lrp6 in mediating Wnt3a signaling in osteoblasts, neonatal calvarial osteoblasts isolated from C57Bl6 (WT) and osteoblasts lacking Lrp5 (Lrp5KO), Lrp6 (Lrp6KO) and, both Lrp5 and 6 (Lrp5/6KO) were treated with Wnt3a for 24 hours and gene expression changes were quantified by RNA-seq.

Analysis of SOX2 downregulation under self-renewal conditions.

Project description:SXO2 is one of the factors involved in maintaining self-renewal and pluripotency in hESCs. This study was performed to reveal the effects of reduced SOX2 levels in self-renewing pluripotent hESCs.

Pharmaceutical reversal of Dkk1-induced LRP6 endocytosis prevents cancer cachexia and prolongs survival

Project description:Cancer cachexia with profound weight loss and frailty impairs quality of life, limits cancer therapy and decreases survival, against which no effective therapy is available. Dkk1 is a secreted antagonist of Wnt/β-catenin pathway via interacting with Wnt co-receptors LRP5 and 6 (LRP5/6) and inducing their endocytosis1-4. Although Dkk1 is critical for animal development3,5, its mRNA is undetectable in most adult organs6. Of note, elevated circulating Dkk1 leads to poor prognosis in patients with a variety of types of cancer by a completely unknown mechanism. Here, we show that administration of a recombinant Dkk1 protein accelerated cancer cachexia-related death through inducing LRP6 endocytosis but not β-catenin inhibition, whereas pharmacological blockade of Dkk1-induced membrane LRP6 downregulation completely prevented cancer cachexia and robustly prolonged survival in tumor-bearing mice. Pharmacological blockade of Dkk1-induced membrane LRP6 downregulation prevented alterations of a number of GPCR pathways and all main cancer cachexia-related pathways in skeletal muscle of mice bearing tumor as shown by a genome-wide transcriptional analysis. Furthermore, Dkk1 injection into hindlimb directly triggered activations of GPCR pathways and cachexia-related pathways. These findings establish a key role of the Dkk1-LRP6 axis in cancer cachexia development through affecting GPCR pathways and suggest a highly promising therapeutic approach for preventing cancer cachexia.

Esrrb plays an important role in maintaining self-renewal of trophoblast stem cells (TSCs) and reprogramming somatic cells to induced TSCs [ChIP-Seq]

Project description:Trophoblast stem cells (TSCs) are derived from the trophoectoderm of a blastocyst and can maintain self-renewal in vitro. Meanwhile, essential insights into the molecular mechanisms controlling placental developmental could be gained by using TSCs that can differentiate into the various placental trophoblast cell types in vitro. Esrrb is a transcription factor with pivotal roles in maintaining TSCs’ self-renewal, but the exact transcriptional networks that Esrrb involved in TSCs are largely unknown. In the present study, we elucidated the function of Esrrb during TSC self-renewal and differentiation. We demonstrate that precise levels of Essrb are critical for TSCs stemness maintenance and normal trophoblast differentiation, as Esrrb depletion results in down-regulation of the key TSC-specific transcription factors, consequently causing TSCs differentiation and forced expression of Esrrb can partially block TSCs differentiation in the absence of FGF4. This function of Esrrb is exerted by directly binding and activating a core set of TSC-specific target genes including Cdx2, Eomes, Sox2, Fgfr4 and BMP4. Furthermore, we investigate the role of Esrrb in reprogramming of mouse embryonic fibroblasts (MEFs) to induced TSCs (iTSCs). We show that Esrrb can facilitate the conversion of iTSCs from MEFs. Moreover, Esrrb can substitute for Eomes during this conversion process. Our findings provide a better understanding of the molecular mechanism of Esrrb in maintaining TSCs self-renewal and iTSCs reprogramming.

Asymmetric self-renewal associated (ASRA) genes

Project description:Cell lines geneticially engineered to undergo conditional asymmetric self-renewal were used to identify genes whose expression is asymmetric self-renewal associated (ASRA). Non-random sister chromatid segregation occurs concordantly with asymmetric self-renewal in these cell lines. Asymmetric self-renewal occurs when murine embryo fibroblasts that are otherwise p53-null are induced to express physiological levels of wildtype p53 protein (Asym). To distinguish p53-responsive genes that also require induction of asymmetric self renewal (i.e., ASRA genes) and/or non-random sister chromatid segregation for change, an additional control cell line, which continues to symmetrically self-renew (with random sister chromatid segregation) even when p53 is induced, was also compared (Symp53). This congenic cell line constitutively expresses the type II inosine monophosphate dehydrogenase (IMPDH II; the rate-limiting enzmye for guanine ribonucleotide biosynthesis) and, thereby, prevents p53-induced asymmetric self-renewal and non-random sister chromatid segregation. Three biological replicates of asymmetrically self-renewing cultures (Asym1-3) were compared with cultures that were symmetrically self-renewing - either because they did not express p53 (3 biological replicates, Sym1-3) or they expressed constitutive IMPDH II (i.e., not regulated by p53) as well as p53 (2 biological replicates, Symp53_1 and 2.)
