TS binds to cell surfaces and to matrix macromolecules such as collagen, fibronectin, and heparin (heparan sulfate). We have isolated one of the complementary DNA (cDNA) clones of TS from human endothelial cell cDNA libraries. With the TS cDNA as a probe, we used Northern blot analysis to look at TS messenger RNA (mRNA) levels of rat aortic SMCs in a quiescent state and cultured under different stimuli. Treatment with platelet-derived growth factor (PDGF) caused a rapid increase of TS mRNA at 2 to 4 hours. This induction was enhanced by the addition of cycloheximide, suggesting that the induction of TS by PDGF does not require the synthesis of new protein species. Transforming growth factor beta (TGF-β) also induced mRNA of TS at 8 hours after stimulation and the induction was blocked by cycloheximide, suggesting that TGF-β requires the mediation of new protein synthesis to induce a TS gene. In measangial cells, we observed the same type of gene expression of TS using an in-situ hybridization study. We conclude that during SMC and mesangial cell proliferation, the induction of TS mRNA is regulated in a specific manner by PDGF and TGF-β.</p></div>","PeriodicalId":77636,"journal":{"name":"The Journal of diabetic complications","volume":"5 2","pages":"Pages 121-123"},"PeriodicalIF":0.0,"publicationDate":"1991-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0891-6632(91)90040-V","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12933675","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}

Therefore, by measuring both urinary IgG1 and IgG4 excretions, the stage of charge selectivity impairment in the nephropathy of NIDDM may be elucidated. Results were expressed as urinary excretion rate (IgG1 ER, IgG4 ER) and compared between diabetic patients with different urinary excretion rates of albumin (AER). IgG4 ER increased to the stage in which AER was more than 10 μg/min, whereas IgG1 ER did not increase to the stage of AER between 10 and 100 μg/min.
