  • We identified protein-coding variants and performed rare variant association analyses in unrelated participants of European ancestry, including 1647 IPAH cases and 18,819 controls. (biomedcentral.com)
  • For pediatric PAH, predicted deleterious de novo variants exhibited a significant burden compared to the background mutation rate (2.45×, p = 2.5e−5). (biomedcentral.com)
  • Epigenetic silencing and loss-of-function mutation of negative regulators of the canonical WNT pathway occur in a variety of human cancer. (aacrjournals.org)
  • In FOP, the mutant receptor causes up-regulation of a transcriptional factor, Id1 . (biomedcentral.com)
  • In parallel, we have performed RNA-seq analysis between wild-type and BMP mutant intestines to identify novel evolutionarily conserved downstream targets of BMP-signaling and are currently analyzing the results in both fly and mouse tissues. (utsw.edu)
  • Quantification of change in the total bone volume by whole body CT scanning could be a reliable evaluation tool for disease progression in forthcoming clinical trials of FOP. (biomedcentral.com)
  • These organoids include a polarized epithelial layer that surrounds a functional lumen and contains cell types of the intestinal epithelium present in proportions and relative spatial arrangement that mimic what is observed in vivo. (stemcell.com)
  • Diagram of the small intestinal epithelium highlighting the identity and spatial arrangement of key epithelial cell types. (stemcell.com)
  • The adult intestinal epithelium is primarily composed of six cell types that are arranged in a crypt-villus structure (Figure 1). (stemcell.com)
  • The receptor (5‐HTR) and transporter (5‐HTT) of serotonin (5‐HT), and VPAC [the receptors of vasoactive intestinal peptide (VIP)] are all coupled to G‐protein 128,136. (comprehensivephysiology.com)
  • In summary, the sGC activator runcaciguat significantly prevented a decline in kidney function in a DKD rat model that mimics common comorbidities and conditions of oxidative stress of CKD patients. (bvsalud.org)
  • To create a favorable osteogenic environment, β-TCP scaffolds have been modified in a number of ways to boost bone healing, including modulating physical features (e.g., pore sizes, porosity and surface roughness), combining with ionic components, and the addition/delivery of growth factors. (frontiersin.org)
  • Growth inhibitor from BSC-1 cells closely related to platelet type beta transforming growth factor. (academicinfluence.com)
  • HA is synthesized in the absence of a protein core at the inner face of the plasma membrane and consequently found in the form of free chains whereas other GAG types are covalently bound into protein cores to form proteoglycans (PGs). (hindawi.com)
  • Consequently, enhancing the adhesion of MSCs, augmenting the release of growth factors, and promoting angiogenic potential of biomaterial scaffolds after implantation are pivotal for successful bone regeneration. (frontiersin.org)
  • This accumulation of mutations may take decades, which is one reason that cancer incidence increases with age. (bbvaopenmind.com)
