The supernatant from a 10% homogenate of brain material was inoculated into African green monkey kidney cells and BSC-1 cells which are permissive for SV40. However no cytopathic effect (CPE) developed and no virus was isolated. The brain supernatant agglutinated human group O erythrocytes and contained 5120 units/mL. The Hirt supernatant from the brain contained three DNA bands corresponding to forms I, II and III of circular double-stranded viral DNA. Restriction endonuclease cleavage analysis revealed that this viral DNA was different from SV40 DNA, but similar to JC virus DNA. After cloning of this viral DNA into pBR322 at the BamHI site, DNA homology of this virus and of SV40 was investigated. Cloned DNA from the brain hybridized with all the HpaI/EcoRI fragments of the SV40 genome at the effective temperature of Tm -50 degrees C [corrected]. At Tm -28 degrees C, however, the cloned DNA hybridized with only HpaI/EcoRI fragment B of the SV40 genome. In contrast to this, JC virus DNA hybridized with all five EcoRI/BamHI/HindIII fragments of cloned DNA even at Tm -28 degrees C.

Many forms of proteoglycans are present in virtually all extracellular matrices of connective tissues. The major biological function of proteoglycans derives from the physicochemical characteristics of the glycosaminoglycan component of the molecule, which provides hydration and swelling pressure to the tissue enabling it to withstand compressional forces. This function is best illustrated by the most abundant proteoglycan in cartilage tissues, aggrecan. During the past decade, diverse species of proteoglycans have been identified in many connective tissues, on cell surfaces and in intracellular compartments. These proteoglycans have distinct biological functions apart from their hydrodynamic functions, and their involvement in many aspects of cell and tissue activities has been demonstrated. For example, decorin, which is widely distributed in many connective tissues, may have functions in regulating collagen fibril formation and in modifying the activity of transforming growth factor-beta; perlecan, the major heparan sulfate proteoglycan in the glomerular basement membrane, may play an important role as the major anionic site responsible for the charge selectivity in glomerular filtration. Specific interactions between proteoglycans (through both their glycosaminoglycan and core protein components) and macromolecules in the extracellular matrix are the key factors in the functions of proteoglycans. Exciting biological functions of proteoglycans are now gradually emerging.</p>","PeriodicalId":75413,"journal":{"name":"Acta pathologica japonica","volume":"43 6","pages":"283-93"},"PeriodicalIF":0.0,"publicationDate":"1993-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/j.1440-1827.1993.tb02569.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19333008","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}

A significant correlation between BrdU labeling index (LI) was observed in each positive ratio (PR, positive/total neoplastic cells) for nuclear antigens in tumor-sections which had been labeled in vivo with BrdU.
