The extracellular regulation of bone morphogenetic protein signaling.

ABSTRACT: In many cases, the level, positioning and timing of signaling through the bone morphogenetic protein (BMP) pathway are regulated by molecules that bind BMP ligands in the extracellular space. Whereas many BMP-binding proteins inhibit signaling by sequestering BMPs from their receptors, other BMP-binding proteins cause remarkably context-specific gains or losses in signaling. Here, we review recent findings and hypotheses on the complex mechanisms that lead to these effects, with data from developing systems, biochemical analyses and mathematical modeling.

Regulation of Bone Morphogenetic Protein Signaling by ADP-ribosylation.

Project description:We previously established a mechanism of negative regulation of transforming growth factor β signaling mediated by the nuclear ADP-ribosylating enzyme poly-(ADP-ribose) polymerase 1 (PARP1) and the deribosylating enzyme poly-(ADP-ribose) glycohydrolase (PARG), which dynamically regulate ADP-ribosylation of Smad3 and Smad4, two central signaling proteins of the pathway. Here we demonstrate that the bone morphogenetic protein (BMP) pathway can also be regulated by the opposing actions of PARP1 and PARG. PARG positively contributes to BMP signaling and forms physical complexes with Smad5 and Smad4. The positive role PARG plays during BMP signaling can be neutralized by PARP1, as demonstrated by experiments where PARG and PARP1 are simultaneously silenced. In contrast to PARG, ectopic expression of PARP1 suppresses BMP signaling, whereas silencing of endogenous PARP1 enhances signaling and BMP-induced differentiation. The two major Smad proteins of the BMP pathway, Smad1 and Smad5, interact with PARP1 and can be ADP-ribosylated in vitro, whereas PARG causes deribosylation. The overall outcome of this mode of regulation of BMP signal transduction provides a fine-tuning mechanism based on the two major enzymes that control cellular ADP-ribosylation.

Regulation of Parietal Cell Homeostasis by Bone Morphogenetic Protein Signaling.

Project description:Background and aimsLoss of bone morphogenetic protein (BMP) signaling in the stomach, achieved by transgenic expression of the BMP inhibitor noggin (H + /K + -Nog mice), causes parietal cell (PC) loss, spasmolytic polypeptide-expressing metaplasia, a marker of preneoplasia, and activation of cell proliferation. We examined if specific inhibition of BMP signaling in PCs leads to aberrations in epithelial homeostasis.MethodsMice with floxed alleles of BMP receptor 1a (Bmpr1a flox/flox mice) were crossed to H + /K + -Cre mice to generate H + /K + -Cre;Bmpr1a flox/flox mice. Morphology of the mucosa was analyzed by hematoxylin and eosin staining. Distribution of H+/K+-ATPase-, IF-, and Ki-67-positive cells was analyzed by immunostaining. Expression of pit and neck cell mucins was determined by staining with the lectins Ulex Europaeus Agglutinin 1 and Griffonia (Bandeiraea) simplicifolia lectin II, respectively. Isolation of PCs from control and Nog-expressing mice was achieved by crossing H + /K + -Nog mice to Rosa26-tdTomato (Tom) mice to generate H + /K + -Nog;Rosa26-tdTom mice. H + /K + -Cre mice were then crossed to H + /K + -Nog;Rosa26-tdTom mice to generate H + /K + -Cre;H + /K + -Nog;Rosa26-tdTom mice. Tom-labeled PCs were purified by flow cytometry. Changes in PC transcripts were measured by RNA-Seq.ResultsSix-month-old H + /K + -Cre;Bmpr1a flox/flox mice exhibited increased epithelial cell proliferation, presence of transitional cells showing colocalization of IF with both Griffonia (Bandeiraea) simplicifolia lectin II-binding mucins and the H+/K+-ATPase, and expansion of Ulex Europaeus Agglutinin 1-positive cells. PC transcripts from Nog-expressing mice demonstrated induction of markers of Spasmolytic Polypeptide-Expressing Metaplasia.ConclusionPC-specific loss of BMP signaling alters the homeostasis of the gastric epithelium leading to the development of metaplasia.

Molecular regulation of matrix extracellular phosphoglycoprotein expression by bone morphogenetic protein-2.

Project description:Matrix extracellular phosphoglycoprotein (MEPE) is mainly expressed in mineralizing tissues, and its C-terminal proteolytic cleavage product is an acidic-serine-asparate-rich-MEPE-associated motif (ASARM) that is a strong regulator of body phosphate metabolism and mineralization. There is sufficient data supporting a role for MEPE protein function in mineralization, however, little is known about the regulation of MEPE gene expression. As bone morphogenetic protein-2 (BMP-2) is one of the most important signals for calvarial mineralization and MEPE expression is higher in mineralized tissues, we attempted to uncover a regulatory circuit between BMP-2 and MEPE expression. Mepe expression is very low in proliferating MC3T3-E1 cells, but is dramatically increased in the mineralization stage and is strongly stimulated by treatment with BMP-2, even in proliferating cells. Overexpression and knock-down experiments of Smads, Dlx5, and Runx2 indicated that they are indispensable mediators of BMP-2-induced Mepe expression. In contrast, Msx2 showed strong inhibition of Mepe transcription. PHEX is an enzyme that prevents the release of the ASARM motif, a mineralization inhibitor, from the MEPE molecule. Thus, the MEPE/PHEX ratio may be a good indicator of mineralization progression because we found that the mRNA ratio and protein levels were low when osteoblasts were actively differentiating to the mineralization stage and the ratio was high when the cells reached the mineralization stage when it is assumed that osteocytes may protect themselves and make a space to survive from the mineralized matrix by releasing the ASARM motif. Collectively, MEPE expression is bone cell-specific and induced by the BMP-2 signaling pathway. In addition, the MEPE/PHEX ratio of the cell could be a very important barometer indicating the progression of tissue mineralization.

Extracellular Regulation of Bone Morphogenetic Protein Activity by the Microfibril Component Fibrillin-1.

Project description:Since the discovery of bone morphogenetic proteins (BMPs) as pluripotent cytokines extractable from bone matrix, it has been speculated how targeting of BMPs to the extracellular matrix (ECM) modulates their bioavailability. Understanding these processes is crucial for elucidating pathomechanisms of connective tissue disorders characterized by ECM deficiency and growth factor dysregulation. Here, we provide evidence for a new BMP targeting and sequestration mechanism that is controlled by the ECM molecule fibrillin-1. We present the nanoscale structure of the BMP-7 prodomain-growth factor complex using electron microscopy, small angle x-ray scattering, and circular dichroism spectroscopy, showing that it assumes an open V-like structure when it is bioactive. However, upon binding to fibrillin-1, the BMP-7 complex is rendered into a closed ring shape, which also confers latency to the growth factor, as demonstrated by bioactivity measurements. BMP-7 prodomain variants were used to map the critical epitopes for prodomain-growth factor and prodomain-prodomain binding. Together, these data show that upon prodomain binding to fibrillin-1, the BMP-7 complex undergoes a conformational change, which denies access of BMP receptors to the growth factor.

Cell trafficking and regulation of osteoblastogenesis by extracellular vesicle associated bone morphogenetic protein 2.

Project description:Extracellular vesicles (EVs) are characterized by complex cargo composition and carry a wide array of signalling cargo, including growth factors (GFs). Beyond surface-associated GFs, it is unclear if EV intralumenal growth factors are biologically active. Here, bone morphogenetic protein-2 (BMP2), loaded directly into the lumen of EVs designated engineered BMP2-EVs (eBMP2-EVs), was comprehensively characterized including its regulation of osteoblastogenesis. eBMP2-EVs and non-EV 'free' BMP2 were observed to similarly regulate osteoblastogenesis. Furthermore, cell trafficking experiments suggest rapid BMP2 recycling and its extracellular release as 'free' BMP2 and natural occurring BMP2-EVs (nBMP2-EVs), with both being osteogenic. Interestingly, BMP2 occurs on the EV surface of nBMP2-EVs and is susceptible to proteolysis, inhibition by noggin and complete dissociation from nBMP2-EVs over 3 days. Whereas, within the eBMP2-EVs, BMP2 is protected from proteolysis, inhibition by noggin and is retained in EV lumen at 100% for the first 24 h and ∼80% after 10 days. Similar to 'free' BMP2, bioprinted eBMP2-EV microenvironments induced osteogenesis in vitro and in vivo in spatial registration to the printed patterns. Taken together, BMP2 signalling involves dynamic BMP2 cell trafficking in and out of the cell involving EVs, with distinct differences between these nBMP2-EVs and eBMP2-EVs attributable to the BMP2 cargo location with EVs. Lastly, eBMP2-EVs appear to deliver BMP2 directly into the cytoplasm, initiating BMP2 signalling within the cell, bypassing its cell surface receptors.

Regulation of bone morphogenetic protein 4 on epithelial tissue.

Project description:Epithelial tissues provide tissue barriers and specialize in organs and glands. When epithelial homeostasis is physiologically or pathologically stimulated, epithelial cells produce mesenchymal cells through the epithelial-mesenchymal transition, forming new tissues, promoting the cure of diseases or leading to illness. A variety of cytokines are involved in the regulation of epithelial cell differentiation. Bone morphogenetic proteins (BMPs), especially the bone morphogenetic protein 4 (BMP4) has a variety of biological functions and plays a prominent role in the regulation of epithelial cell differentiation. BMP4 is an important regulatory factor of a series of life activities in vertebrates, which is also related to cell proliferation, differentiation and mobility, it also has relation with tumor development. This paper mainly reviews the mechanism of BMP4's regulation on epithelial tissues, as well as its effect on the growth, differentiation, benign lesions and malignant lesions of epithelial tissues, and expounds the function of BMP4 in epithelial tissues, to provide theoretical support for the research on reducing epithelial diseases.

Role of RGM coreceptors in bone morphogenetic protein signaling.

Project description:BackgroundThe repulsive guidance molecule (RGM) proteins, originally discovered for their roles in neuronal development, have been recently identified as co-receptors in the bone morphogenetic protein (BMP) signaling pathway. BMPs are members of the TGFbeta superfamily of signaling cytokines, and serve to regulate many aspects of cellular growth and differentiation.ResultsHere, we investigate whether RGMa, RGMb, and RGMc play required roles in BMP and TGFbeta signaling in the mouse myoblast C2C12 cell line. These cells are responsive to BMPs and are frequently used to study BMP/TGFbeta signaling pathways. Using siRNA reagents to specifically knock down each RGM protein, we show that the RGM co-receptors are required for significant BMP signaling as reported by two cell-based BMP activity assays: endogenous alkaline phosphatase activity and a luciferase-based BMP reporter assay. Similar cell-based assays using a TGFbeta-induced luciferase reporter show that the RGM co-receptors are not required for TGFbeta signaling. The binding interaction of each RGM co-receptor to each of BMP2 and BMP12 is observed and quantified, and equilibrium dissociation constants in the low nanomolar range are reported.ConclusionOur results demonstrate that the RGMs play a significant role in BMP signaling and reveal that these molecules cannot functionally compensate for one another.

The protein kinase LKB1 negatively regulates bone morphogenetic protein receptor signaling.

Project description:The protein kinase LKB1 regulates cell metabolism and growth and is implicated in intestinal and lung cancer. Bone morphogenetic protein (BMP) signaling regulates cell differentiation during development and tissue homeostasis. We demonstrate that LKB1 physically interacts with BMP type I receptors and requires Smad7 to promote downregulation of the receptor. Accordingly, LKB1 suppresses BMP-induced osteoblast differentiation and affects BMP signaling in Drosophila wing longitudinal vein morphogenesis. LKB1 protein expression and Smad1 phosphorylation analysis in a cohort of non-small cell lung cancer patients demonstrated a negative correlation predominantly in a subset enriched in adenocarcinomas. Lung cancer patient data analysis indicated strong correlation between LKB1 loss-of-function mutations and high BMP2 expression, and these two events further correlated with expression of a gene subset functionally linked to apoptosis and migration. This new mechanism of BMP receptor regulation by LKB1 has ramifications in physiological organogenesis and disease.
