The role of acetylation in rDNA transcription [PDF]

Nucleic Acids Research, 2001
Treatment of NIH 3T3 cells with trichostatin A (TSA), an inhibitor of histone deacetylase (HDAC), resulted in a dose-dependent increase in transcription from a rDNA reporter and from endogenous rRNA genes. Chromatin immunoprecipitation using anti-acetyl-histone H4 antibodies demonstrated a direct effect of TSA on the acetylation state of the ribosomal ...

Comparative analysis of the location of rDNA in the Palaearctic bushcricket genus Isophya (Orthoptera: Tettigoniidae: Phaneropterinae)

European Journal of Entomology, 2011
The present study focused on the evolution of the karyotype in 21 taxa of the genus Isophya, which was done by mapping the location on the chromosomes of ribosomal RNA (rRNA) coding genes using fluorescence in situ hybridization (FISH) with an 18S rDNA ...

Molecular variations in Lenzites species collected from Nigeria and other parts of the world using Internal Transcribed Spacers (ITS) regions of Ribosomal RNA [PDF]

Microbial Biosystems Journal, 2018
The phylogeny of six specimens of Lenzites species collected from Akure Nigeria was studied using molecular data obtained by sequencing the internal transcribed spacers (ITS) regions of ribosomal RNA using universal primers (ITS4 and ITS5).

Next generation sequencing analysis reveals a relationship between rDNA unit diversity and locus number in Nicotiana diploids

, 2012
Background Tandemly arranged nuclear ribosomal DNA (rDNA), encoding 18S, 5.8S and 26S ribosomal RNA (rRNA), exhibit concerted evolution, a pattern thought to result from the homogenisation of rDNA arrays. However rDNA homogeneity at the single nucleotide

Function of the upstream activating factor in chromatin structure organization and transcriptional regulation at the yeast ribosomal DNA

, 2010
Chromatin is the template of all processes involved in DNA metabolism in the eukaryotic cell. Accordingly, chromatin is a dynamic structure which changes in its composition and posttranslational modification correlating with the functional state of a ...

Copy Number Variations of Human Ribosomal Genes in Health and Disease: Role and Causes

Frontiers in Bioscience-Landmark
Background: A number of association studies have linked ribosomal DNA gene copy number (rDNA CN) to aging and pathology. Data from these studies are contradictory and depend on the quantitative method.
