In infiltrating ductal and lobular carcinomas (IDC, ILC), laminin reactivity was weak, uneven or absent around neoplastic clusters whereas stromal staining for Ten and cFn was extensive and strong. In most IDC, moderate β-1 and α-6 staining involved variable subpopulations; one mucinous carcinoma stained strongly and diffusely. In 20–40% of cells in ILC, β-1 and α-6 were localized in delicate, ramified cytoplasmic processes.

Reactivity for β-1 and α-6 integrin subunits is decreased in all breast carcinomas; however, the comparatively strong and distinctly localized reactions noted in lobular vs ductal carcinomas may well reflect biological and clinical differences between these two main breast carcinoma phenotypes.</p></div>","PeriodicalId":77508,"journal":{"name":"Cell differentiation and development : the official journal of the International Society of Developmental Biologists","volume":"32 3","pages":"Pages 409-416"},"PeriodicalIF":0.0,"publicationDate":"1990-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0922-3371(90)90057-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12876047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The angiogenic factor basic fibroblast growth factor (bFGF) induces increased synthesis of both plasminogen activator and collagenase in endothelial cells.

Increased production of plasmin may be responsible for the release of soluble complexes of heparan sulfate-bFGF which may be the active form of bFGF. The activity of a negative regulator of angiogenesis, transforming growth factor β (TGF-β), is also regulated by proteases since the released latent form of TGF-β is activated by a surface proteolytic assembly plasminogen activator and plasmin.

Glomerulonephritis is an inflammation of the kidney that is characterized by the accumulation of extracellular matrix within the damaged glomeruli. We have shown that transforming growth factor-β1 (TGF-β1) is unique in regulating the production of proteoglycans and matrix glycoproteins by glomerular cells in vitro. In an experimental model of glomerulonephritis in rats, we found increased proteoglycan and fibronectin synthesis by cultured nephritic glomeruli, which was greatly reduced by the addition of antiserum to TGF-β1. Conditioned media from glomerular cultures, when added to normal cultured mesangial cells, induced elevated proteoglycan synthesis. The stimulatory activity of the conditioned media was blocked by addition of TGF-β1 antiserum. Glomerular histology showed mesangial matrix expansion in a time course that roughly paralleled the elevated proteoglycan synthesis by the nephritic glomeruli. At the same time there was an increased expression of TGF-β1 mRNA and TGF-β1 protein in the glomeruli. Administration of anti-TGF-β1 at the time of induction of glomerulonephritis suppressed the elevated extracellular matrix production and dramatically attenuated histological manifestations of the disease. A small proteoglycan, decorin, also inhibits the activity of TGF-β, potentially providing an alternative format for the prevention of TGF-β activity. Our results provide direct evidence for a causal role of TGF-β1 in the pathogenesis of the experimental disease and suggest a new approach to the therapy of glomerulonephritis.</p></div>","PeriodicalId":77508,"journal":{"name":"Cell differentiation and development : the official journal of the International Society of Developmental Biologists","volume":"32 3","pages":"Pages 425-431"},"PeriodicalIF":0.0,"publicationDate":"1990-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0922-3371(90)90059-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13254603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
