The functions of these complex are unclear but there is some evidence to suggest that binding of p53 to these viral proteins may inactivate p53 functions. Recent reports have shown that p53 is involved in regulation of transcription. In this study we have considered the possibility that p53 may regulate transcription of cytomegalovirus immediate early genes which play a crucial role for virus replication. Here we report that experiments in which NIH 3T3 cells were cotransfected with a p53 expression plasmid together with a reporter gene linked to the mouse cytomegalovirus immediate-early enhancer/promoter revealed that wild type p53 could efficiently reduce the transcriptional activity of this viral regulatory sequence. By contrast expression of a mutated p53 correlated with a much smaller reduction of transcription. Deletion mutants analysis of the enhancer revealed that repression of transcription by p53 requires a minimal promoter containing an SP1 consensus sequence and a TATA box.</p>","PeriodicalId":12722,"journal":{"name":"Giornale di batteriologia, virologia ed immunologia","volume":"86 1-12","pages":"43-54"},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19680973","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}

The etiology of AOM in children is prevalently bacterial; numerous studies have shown the most common etiological agents. But the etiology in adults has not been well studied. The authors examined 40 cases of AOM in adults, the pathologic material was obtained by needle aspiration; in 32 samples there was bacterial growth. In the majority of the cases (94%) the bacteria isolated were the same as those found in children: S. pneumoniae, H. influenzae and B. catarrhalis; much rarer were S. pyogenes and S. aureus. On the potential beta-lactamase producing strains, this activity was measured.
