Our previous studies have analyzed the increased proliferation of cystic epithelial cells and this study examines the basis of increased proliferation of interstitial fibroblasts associated with ADPKD disease progression. ADPKD fibroblasts show phenotypic alterations<em>in vitro,</em>have acquired the capacity to grow in soft agar, and show an increased mitogenic response to a variety of growth factors particularly acidic FGF (aFGF). ELISA, Western immunoblot analysis, and immunocytochemistry showed increased aFGF content in ADPKD tissues and fibroblasts in culture, and aFGF was secreted into the extracellular matrix and conditioned medium, respectively. No alterations in aFGF receptor number were found, but Scatchard analysis of¹²⁵I-aFGF binding suggested an increased affinity of binding to the low affinity receptor, and covalent cross-linking analysis suggested the presence of novel putative receptors (120 kDa) in ADPKD fibroblasts. Signaling abnormalities were found, since aFGF incubation resulted in the tyrosine phosphorylation of additional substrates, more rapidly and for a more sustained duration in ADPKD fibroblasts than in normal fibroblasts. These findings suggest an important role for acidic FGF in the hyperproliferation of interstitial fibroblasts associated with disease progression in human ADPKD.</p></div>","PeriodicalId":8837,"journal":{"name":"Biochemical and molecular medicine","volume":"61 2","pages":"Pages 178-191"},"PeriodicalIF":0.0,"publicationDate":"1997-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1006/bmme.1997.2583","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20203260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These changes were related to important alterations in protein turnover in skeletal muscle. Thus, the diabetic animals showed changes in the fractional protein rates of both synthesis (decreased by 37%) and degradation (increased by 140%). The increased protein degradation observed in the muscle of the diabetic animals was associated with important changes in the concentration of both circulating and muscle amino acids. Interestingly, the diabetic animals did not show important changes in either liver or kidney protein turnover rates, in spite of having a clear increase (over 50%) in kidney mass. In addition, and although the total amino acid concentration was not affected by the diabetic state, the chemically induced diabetic animals showed important elevations of branched-chain amino acids (leucine, isoleucine, and valine) in both blood and skeletal muscle. Similarly, important decreases in the blood concentrations of glutamate + glutamine, alanine, glycine, proline, serine, and threonine were also observed.
