Variations in transcriptional activity of rDNA spacer promoters.
We have compared the DNA sequences of several different examples of the duplicated polymerase I promoters that are found in rDNA spacers of Xenopus laevis. Although different spacers exhibit different amounts of transcription in vivo, this does not seem to be due to DNA sequence differences between spacer promoters. We have found that several different spacer promoters when subcloned and inject...
متن کاملAg-NOR and P53 Expression of the breast cancer in correlation with tumor grade
Objective: Breast cancer comprise approximately one third of malignant cases in women and is considered as the most common invasive condition in women at an age range of 15-54 years and as the second most prevalent cause of mortality at an age range of 55-74 years. Tumor inhibiting factor p53 is a vital ...
متن کاملSimultaneous ultrastructural localization of Ag-NOR (nucleolar organizer region) proteins and ribonucleoproteins during mitosis, in human breast cancerous tissues.
The simultaneous ultrastructural localization of the Ag-NOR proteins and ribonucleoproteins (RNP) was carried out during mitosis in human breast cancerous tissues using a one-step silver staining method followed by acetylation. Owing to the good preservation of the cells and to the high precision of the Ag staining we were able to follow the behaviour of the argyrophilic nucleolar components fr...
متن کاملPlant rDNA database: update and new features
UNLABELLED The Plant rDNA database (www.plantrdnadatabase.com) is an open access online resource providing detailed information on numbers, structures and positions of 5S and 18S-5.8S-26S (35S) ribosomal DNA loci. The data have been obtained from >600 publications on plant molecular cytogenetics, mostly based on fluorescent in situ hybridization (FISH). This edition of the database contains inf...
متن کاملNucleolar Association and Transcriptional Inhibition through 5S rDNA in Mammals
Changes in the spatial positioning of genes within the mammalian nucleus have been associated with transcriptional differences and thus have been hypothesized as a mode of regulation. In particular, the localization of genes to the nuclear and nucleolar peripheries is associated with transcriptional repression. However, the mechanistic basis, including the pertinent cis- elements, for such asso...
