The embryonic formation of midbrain dopaminergic (mDA) neurons in vivo provides critical guidelines for the in vitro differentiation of mDA neurons from stem cells, currently being developed for Parkinson's disease cell replacement therapy. Bone morphogenetic protein (BMP)/SMAD inhibition is routinely used during early steps of stem cell differentiation protocols, including for the generation of mDA neurons. However, the function of the BMP/SMAD pathway for in vivo specification of mammalian mDA neurons is virtually unknown...

Hyperphosphatemia and vascular calcification are frequent complications of chronic renal failure and bone morphogenetic protein 7 (BMP7) has been shown to protect against development of vascular calcification in uremia. The present investigation examined the potential reversibility of established uremic vascular calcification by treatment of uremic rats with BMP7. A control model of isogenic transplantation of a calcified aorta from uremic rats into healthy littermates examined whether normalization of the uremic environment reversed vascular calcification...

Kidney mainly arises from the induction of metanephric mesenchymal cells (MM cells) and the ureteric bud (UB). Transmembrane protein-100 (Tmem100) consists of two transmembrane regions with strong temporal and spatial expression characteristics during renal development. However, the function of Tmem100 in mouse embryonic kidney-derived cells remained unclear. We provided qPCR to verify the relationship between Tmem100 and the BMP signal pathway. To clarify the role of Tmem100 in cell proliferation and apoptosis, we carry out EdU incorporation, annexin V- fluorescein isothiocyanate (FITC) apoptosis assay...

Osteoporotic patients often suffer from bone fracture but its healing is compromised due to impaired osteogenesis potential of bone marrow-derived mesenchymal stem cells (BMSCs). Here we aimed to exploit adipose-derived stem cells from ovariectomized rats (OVX-ASCs) for bone healing. We unraveled that OVX-ASCs highly expressed miR-214 and identified 2 miR-214 targets: CTNNB1 (β-catenin) and TAB2. We demonstrated that miR-214 targeting of these two genes blocked the Wnt pathway, led to preferable adipogenesis and hindered osteogenesis...

Despite expressing high levels of the epidermal growth factor receptor (EGFR), a majority of oral squamous cell carcinoma (OSCC) patients show limited response to cetuximab and ultimately develop drug resistance. However, mechanism underlying cetuximab resistance in OSCC is not clearly understood. Here, using a mouse orthotopic xenograft model of OSCC, we show that BMP7-p-Smad1/5/8 signaling contributes to cetuximab resistance. Tumor cells isolated from the recurrent cetuximab-resistant xenograft models exhibited low EGFR expression but extremely high levels of phosphorylated Smad-1, -5, and -8 (p-Smad1/5/8)...

Knowledge of the molecules used by the maternal reproductive tract to regulate development of the preimplantation embryo is largely incomplete. The goal of the present experiment was to identify candidates for this function. The approach was to assess expression patterns in the endometrium and oviduct of 93 genes encoding for hormones, growth factors, chemokines, cytokines, and WNT-related molecules. Results show that all of the genes were expressed in the reproductive tract. Expression in oviduct was affected by day of the estrous cycle for 21 genes with 11 genes having highest expression at estrus (CCL21, CTGF, CXCL10, CXCL16, DKK3, FGF10, IL18, IL33, IL34, PGF, and SFRP2), one gene at d 3 (WNT4), 8 at d 5 (BMP7, HGF, IL6, SFRP1, TGFB1, WIF1, WNT2, and WNT5A), and one at d 7 (IK)...

BACKGROUND/OBJECTIVES: Serotonin is synthesized by many cells in the periphery to affect vasoconstriction, intestinal motility, and glucose and lipid metabolism. It has recently been shown that serotonin leads to fat accumulation in white adipose tissue (WAT). However, the direct effect of serotonin on adipose tissue (BAT) differentiation and metabolism is limited. Therefore, our aim was to investigate the effect of serotonin on brown adipocyte metabolism and differentiation. METHODS: Non-differentiated HIB1B cells and differentiated HIB1B brown adipocytes were treated with serotonin and their metabolism and differentiation examined...

In the last decade, the developments of novel technologies, such as Hi-C or GAM methods, allowed to discover that chromosomes in the nucleus of mammalian cells have a complex spatial organization, encompassing the functional contacts between genes and regulators. In this work, we review recent progresses in chromosome modeling based on polymer physics to understand chromatin structure and folding mechanisms. As an example, we derive in mouse embryonic stem cells the full 3D structure of the Bmp7 locus, a genomic region that plays a key role in osteoblastic differentiation...

Obesity poses a substantial threat of a worldwide epidemic and requires better understanding of adipose-tissue biology as well as necessitates research into the etiology and therapeutic interventions. In this study, Medicarpin (Med), a natural pterocarpan, was selected (by screening) as a small-molecule inducer of adipocyte differentiation among 854 candidates by using C3H10T1/2 mesenchymal stem cell; a cellular model of adipogenesis. Med induced the expression of brown-adipocyte commitment marker Bmp7 as well as the early regulators of brown fat fate Pparγ, Prdm16, and Pgc-1α during differentiation of C3H10T1/2 mesenchymal stem cells...

The regulation of energy balance involves complex processes in the brain, including coordination by hypothalamic neurons that contain pro-opiomelanocortin (POMC). We previously demonstrated that central bone morphogenetic protein 7 (BMP7) reduces appetite. Now we show that a type 1 BMP receptor, BMPR1A, is co-localized with POMC neurons and POMC-BMPR1A-KO mice are hyperphagic, revealing physiological involvement of BMP signaling in anorectic POMC neurons in the regulation of appetite. Surprisingly, the hyperphagic POMC-BMPR1A-KO mice exhibit a lack of obesity, even on a 45% high-fat diet...

The hepatitis C virus (HCV) infection is associated with various extrahepatic manifestations, which are correlated with poor outcomes, and thus increase the morbidity and mortality of chronic hepatitis C (CHC). Therefore, understanding the internal linkages between systemic manifestations and HCV infection is helpful for treatment of CHC. Yet, the mechanism by which the virus evokes the systemic diseases remains to be elucidated. In the present study, using gene set enrichment analysis (GSEA) and signaling pathway impact analysis (SPIA), a comprehensive analysis of microarray data of mRNAs was conducted in HCV-infected and -uninfected Huh7...

Longitudinal bone growth is governed by a complex network of endocrine signals including leptin. In mouse, leptin deficiency leads to distinct phenotypes in bones of the limb and spine, suggesting the appendicular and axial skeletons are subject to differential regulation by leptin. We established primary cultures for the chondrocytes from tibial and vertebral epiphyseal plates. Cellular proliferation and apoptosis were analyzed for the chondrocytes that had been treated with various concentrations of leptin...

BACKGROUND: Ovulation rate and litter size are important reproductive traits in sheep with high economic value. Recent work has revealed a potential link between DNA methylation and prolificacy. However, a genome-wide study that sought to identify potential DNA methylation sites involved in sheep prolificacy indicated that it is still unknown. Here, we aimed to investigate the genome-wide DNA methylation profiles of Hu sheep ovaries by comparing a high-prolificacy group (HP, litter size of three for at least 2 consecutive lambings) and low prolificacy group (LP, litter size of one for at least 2 consecutive lambings) using deep whole-genome bisulfite sequencing (WGBS)...

The family of TGF-β and bone morphogenetic protein (BMP) signaling proteins have numerous developmental and physiological roles. They are made as proprotein dimers, then cleaved by proprotein convertases to release the C-terminal domain as an active ligand dimer. Multiple proteolytic processing sites in Glass bottom boat (Gbb), the Drosophila BMP7 ortholog, can produce distinct ligand forms. Cleavage at the S1 or atypical S0 site in Gbb produces Gbb15, the conventional small BMP ligand, while NS site cleavage produces a larger Gbb38 ligand...

Bone morphogenetic protein-7 (BMP-7) counteracts pro-fibrotic effects of TGFβ1 in cultured renal cells and protects from fibrosis in acute and chronic renal injury models. Using the unilateral ureteral obstruction (UUO) model of chronic renal fibrosis, we investigated the effect of exogenous-rhBMP-7 on pro-fibrotic signaling pathways mediated by TGFβ1 and hypoxia. Mice undergoing UUO were treated with vehicle or rhBMP-7 (300μg/kg i.p.) every other day for eight days and kidneys analysed for markers of fibrosis and SMAD, MAPK, and PI3K signaling...

BMP7 is expressed in ureteric buds and cap mesenchyme of the fetal kidney, mediating branching morphogenesis and survival and priming of metanephric mesenchyme. Although dose-dependent effects of BMP7 in collecting duct cells have been reported, studies in metanephric mesenchymal cells are lacking. We examined the effects of BMP7 on MAP kinase activation, proliferation, and expression of cadherins in a metanephric mesenchymal cell line MS7 by thymidine incorporation, immunoblot analysis, and quantitative real-time PCR The levels of phosphorylated ERK (P-ERK) and phosphorylated p38 (P-p38) were not altered at 10 min, 1 h, and 6 h with low-dose BMP7 (0...

Tissue engineered constructs built with human cells capable of generating a bone-like organ within the mouse have attracted considerable interest over the past decade. Here, we aimed to compare the utility of human mesenchymal stem/stromal cells (MSC) isolated from fetal term placenta (fPL-MSC) and fetal first trimester bone marrow (fBM-MSC) in a polycaprolactone scaffold/BMP7-based model in nude mice. Furthermore, fPL-MSC were co-seeded with fetal placenta-derived endothelial colony forming cells (ECFC) to assess the impact of ECFC on fPL-MSC osteogenesis...

Skeletal muscle exhibits remarkable plasticity in its ability to modulate its mass in response to the physiologic changes associated with functional use, systemic disease, and aging. Although a gradual loss of muscle mass normally occurs with advancing age, its increasingly rapid progression results in sarcopenia in a subset of individuals. The identities of muscle-enriched, long noncoding RNAs that regulate this process are unknown. Here, we identify a long noncoding RNA, named Chronos, whose expression in muscle is positively regulated with advancing age and negatively regulated during Akt1-mediated growth...

Cartilage injury can trigger crucial pathomechanisms, including excessive cell death and expression of matrix-destructive enzymes, which contribute to the progression of a post-traumatic osteoarthritis (PTOA). With the intent to create a novel treatment strategy for alleviating trauma-induced cartilage damage, we complemented a promising antioxidative approach based on cell and chondroprotective N-acetyl cysteine (NAC) by chondroanabolic stimulation. Overall, three potential pro-anabolic growth factors - IGF-1, BMP7 and FGF18 - were tested comparatively with and without NAC in an ex vivo human cartilage trauma-model...
