Project description:HOX genes regulate organ development and their abrrative expressions are also implicated in cancer progressions. It is a universal strategy for tumors to regain cell plasticity through disruption of Hox boundaries. Along with this clue, we identified HOXD13 as a pivotal component since HOXD13 deprivation alone is enough to induce more aggressive phenotypes in prostate cancer cells. Here we subjected HOXD13 manipulated prostate cancer cells (LNCaP) to HiSeq RNA-Seq to identify its target genes involved in the antitumor activity.

Project description:Bone morphogenetic protein 4 (BMP4) is essential for lung development. To define its intracellular signaling mechanisms by which BMP4 regulates lung development, BMP-specific Smad1 or Smad5 was selectively knocked out in fetal mouse lung epithelial cells. Abrogation of lung epithelial-specific Smad1, but not Smad5, resulted in retardation of lung branching morphogenesis and reduced sacculation, accompanied by altered distal lung epithelial cell proliferation and differentiation, and consequently severe neonatal respiratory failure. By combining cDNA microarray with ChIP-chip analyses, Wnt inhibitory factor-1 (Wif1) was identified as a novel target gene of Smad1 in the developing mouse lung epithelial cells. Loss of Smad1 transcriptional activation of Wif1 expression was associated with reduced Wif1 expression and increased Wnt/beta-catenin signaling activity in lung epithelia, resulting in specific fetal lung abnormalities. Therefore, a novel regulatory loop of BMP4-Smad1-Wif1-Wnt/beta-catenin in coordinating BMP and Wnt pathways to control fetal lung development is suggested. mRNA profiling: Total RNA was isolated from left lobe lungs of three pair of E18.5 wild type and Smad1 lung epithelium-specific conditional knockout mice

Project description:To confirm that the SMAD1/5- and SMAD4-associated genes are direct transcriptional regulators in mESCs in response to BMP, we treated undifferentiated R1 ES cells with BMP4 or with the BMP4 antagonist noggin, which can inhibit BMP signaling effectively for 4 h. Undifferentiated R1 ES cells were treated for 4 h with BMP4 or with the BMP4 antagonist noggin, which can inhibit BMP signaling effectively. Untreated R1 ES cells served as the control.

Project description:Cardiac lineage specification in the mouse is controlled by TGFβ and WNT signaling. From fly to fish, BMP has been identified as an indispensable heart inducer. A detailed analysis of the role of Bmp4 and its effectors Smad1/5, however, was still missing. We show that Bmp4 induces cardiac mesoderm formation in murine embryonic stem cells in vitro. Bmp4 first activates Wnt3 and upregulates Nodal. pSmad1/5 and the WNT effector Tcf3 form a complex, and together with pSmad2/3 activate mesoderm enhancers and Eomes. They then cooperate with Eomes to consolidate the expression of many mesoderm factors, including T. Eomes and T form a positive feedback loop and open additional enhancers regulating early mesoderm genes, including the transcription factor Mesp1 establishing the cardiac mesoderm lineage. In parallel, the neural fate is suppressed. Our data confirm the pivotal role of Bmp4 in cardiac mesoderm formation in the mouse. We describe in detail the consecutive and cooperative actions of three signaling pathways, BMP, WNT and Nodal, and their effector transcription factors, during cardiac mesoderm specification.

Project description:Endoglin is a membrane glycoprotein primarily expressed by the vascular endothelium and involved in cardiovascular diseases. Upon the proteolytic processing of the membrane-bound protein, a circulating form of endoglin (soluble endoglin, sEng) can be released, and high levels of sEng have been observed in several endothelial-related pathological conditions, where it appears to contribute to endothelial dysfunction. Preeclampsia is a multisystem disorder of high prevalence in pregnant women characterized by the onset of high blood pressure and often associated with increased levels of sEng. Although a pathogenic role for sEng involving hypertension has been reported in several animal models of preeclampsia, the exact molecular mechanisms implicated remain to be identified. To search for sEng-induced mediators, we have analyzed the protein secretome of human endothelial cells in the presence of sEng. We find that sEng induces the expression of BMP4 in endothelial cells, as evidenced by their proteomic signature, gene transcript levels and BMP4 promoter activity. A mouse model of preeclampsia with high sEng plasma levels (sEng+) showed increased levels of BMP4 transcripts in lungs and increased circulating BMP4, compared to those of control animals. In addition, after crossing female wild type with male sEng+ mice, hypertension appears 18 days after mating, precisely coinciding with the appearance of high plasma levels of BMP4. Also, serum levels of sEng and BMP4 are positively correlated in pregnant women with and without preeclampsia. Interestingly, sEng-induced arterial pressure elevation in sEng+ mice was abolished in the presence of the BMP4 inhibitor noggin, suggesting that BMP4 is a downstream mediator of sEng. These results provide a better understanding on the role of sEng in the pathobiology of preeclampsia and other cardiovascular diseases, where sEng levels are increased.

Project description:Vascular remodeling to match arterial diameter to tissue metabolic requirements commonly fails in ischemic disease. Endothelial cells (EC) sense fluid shear stress (FSS) from blood flow to maintain FSS within a narrow range in healthy vessels. Higher FSS induces vessel outward remodeling to return FSS to physiological levels, but mechanisms are poorly understood. We previously reported that Smad1/5 is maximally activated at physiological FSS and suppressed at higher flow. The Smad1/5 pathway opposes activation of Akt, suggesting that inhibiting Smad1/5 may be required for outward remodeling. Here, we report that suppression of Smad1/5 at high FSS is mediated by elevated KLF2, which induces the BMP pathway inhibitor BMPER, which suppresses Smad1/5 and de-inhibits Akt. In a mouse arteriovenous fistula (AVF) model, high FSS induces arterial outward remodeling coincident with elevated BMPER expression and Smad1/5 inactivation. Endothelial BMPER deletion impaired blood flow recovery and vascular remodeling in the AVF and a hindlimb ischemia (HLI) model, with the latter reversed by BMP9/10 blocking antibodies (bAbs). In both STZ-induced type 1 and HFD-induced type 2 diabetic mice that show poor recovery from HLI, BMP9/10 bAbs improved outcomes. Thus, suppression of Smad1/5 is required for high FSS-mediated outward remodeling and is a potential therapeutic approach for ischemic disease.

Project description:Posterior homeobox D genes, in particular HOXD13, are over-expressed by Ewing sarcoma, a tumor driven by the oncogenic fusion protein EWS-FLI1. Here, we have found that EWS-FLI1 maintains HOXD13 expression through a GGAA microsatellite enhancer in the developmental posterior HOXD regulatory domain. Activation of this enhancer is EWS-FLI1 dependent and epigenomic silencing of this region leads to loss of HOXD13 expression in Ewing sarcoma cells, but not in unrelated cells. To determine the function of HOXD13 activation in Ewing sarcoma we performed nascent RNA sequencing upon HOXD13 knockdown. We identified NT5E as a target induced by HOXD13. NT5E encodes for the cell surface marker CD73, so we used CITE-seq to profile these cells.
