During spinal cord development, commissural neurons extend their axons ventrally, away from the roof plate. The roof plate is the source of a diffusible repellent that orients commissural axons in vitro and, thus, may regulate the trajectory of commissural axons in vivo. Of three Bmps expressed in the roof plate, BMP7, but not BMP6 or GDF7, mimics the roof plate activity in vitro. We show here ...
Bone morphogenetic protein-7 (BMP7) is known to antagonize transforming growth factor β 1 (TGFβ1)-mediated fibrosis through suppressing epithelial-mesenchymal transition (EMT). We recently reported that BMP7 also antagonizes the effects of TGFβ1 in breast cancer (BC) tumorigenesis-related EMT. Nevertheless, the control of BMP7 expression in BC remains ill-defined. Here, we detected significantl...
PURPOSE The focus of this study was to determine whether bone morphogenetic proteins (BMPs) trigger reactive gliosis in retinal astrocytes and/or Müller glial cells. METHODS Retinal astrocytes and the Müller glial cell line MIO-M1 were treated with vehicle, BMP7, or BMP4. Samples from the treated cells were analyzed for changes in gliosis markers using reverse transcriptase - quantitative PCR...
Accumulating evidence demonstrated that miRNAs are highly involved in kidney fibrosis and Epithelial-Eesenchymal Transition (EMT), however, the mechanisms of miRNAs in kidney fibrosis are poorly understood. In this work, we identified that miR542-3p could promote EMT through down-regulating bone morphogenetic protein 7 (BMP7) expression by targeting BMP7 3'UTR. Firstly, real-time PCR results sh...
In humans and mice, loss of HOXA13 function causes defects in the growth and patterning of the digits and interdigital tissues. Analysis of Hoxa13 expression reveals a pattern of localization overlapping with sites of reduced Bmp2 and Bmp7 expression in Hoxa13 mutant limbs. Biochemical analyses identified a novel series of Bmp2 and Bmp7 enhancer regions that directly interact with the HOXA13 DN...
Bone Morphogenetic Proteins (BMPs) play multiple and important roles in embryonic development as well as in homeostasis and tissue repair in the adult. Bmp7 has been implicated in developmental disorders and in a variety of diseases, but functional studies to elucidate its role so far have been hampered, since mice deficient in BMP7 die around or just after birth. To facilitate such studies, we...
Telomere maintenance is critical in tumor cell immortalization. Here, we report that the cytokine bone morphogenetic protein-7 (BMP7) inhibits telomerase activity that is required for telomere maintenance in cervical cancer cells. Application of human recombinant BMP7 triggers a repression of the human telomerase reverse transcriptase (hTERT) gene, shortening of telomeres, and hTERT repression-...
While white adipose tissue (AT) is an energy storage depot, brown AT is specialized in energy dissipation. Uncoupling protein 1 (UCP1)-expressing adipocytes with a different origin than classical brown adipocytes have been found in white AT. These "brite" (brown-in-white) adipocytes may represent a therapeutic target to counteract obesity. Bone morphogenetic proteins (BMPs) play a role in the r...
p53 tumor suppressor and its family members, p63 and p73, are known to play a role in the survival of cells exposed to stress signals. As a transcription factor, the p53 family proteins induce a plethora of target genes that mediate their functions in the cell cycle, apoptosis, and other biological activities. However, the mechanism by which the p53 family proteins regulate their cell survival ...
Wang, Shinong and Raimund Hirschberg. BMP7 antagonizes TGF-dependent fibrogenesis in mesangial cells. Am J Physiol Renal Physiol 284: 1006–1013, 2003; 10.1152/ ajprenal.00382.2002.—Exogenous administration of recombinant human bone morphogenetic protein (BMP)-7 was recently shown to ameliorate renal glomerular and interstitial fibrosis in rodents with experimental renal diseases. We tested the ...
