Synergistic activation of Arg1 gene by retinoic acid and IL-4 involves chromatin remodeling for transcription initiation and elongation coupling
All-trans Retinoic acid (RA) and its derivatives are potent therapeutics for immunological functions including wound repair. However, the molecular mechanism of RA modulation in innate immunity is poorly understood, especially in macrophages. We found that topical application of RA significantly improves wound healing and that RA and IL-4 synergistically activate Arg1, a critical gene for tissu...
متن کاملRepeat expansion affects both transcription initiation and elongation in friedreich ataxia cells.
Expansion of a GAA · TTC repeat in the first intron of the frataxin (FXN) gene causes an mRNA deficit that results in Friedreich ataxia (FRDA). The region flanking the repeat on FRDA alleles is associated with more extensive DNA methylation than is seen on normal alleles and histone modifications typical of repressed genes. However, whether these changes are responsible for the mRNA deficit is ...
متن کاملTranscriptional activation domains stimulate initiation and elongation at different times and via different residues.
Transcriptional activators can stimulate multiple steps in the transcription process. We have used GAL4 fusion proteins to characterize the ability of different transcriptional activation domains to stimulate transcriptional elongation on the hsp70 gene in vitro. Stimulation of elongation apparently occurs via a mechanistic pathway different from that of stimulation of initiation: the herpes si...
متن کاملNovel domains and orthologues of eukaryotic transcription elongation factors.
The passage of RNA polymerase II across eukaryotic genes is impeded by the nucleosome, an octamer of histones H2A, H2B, H3 and H4 dimers. More than a dozen factors in the yeast Saccharomyces cerevisiae are known to facilitate transcription elongation through chromatin. In order to better understand the evolution and function of these factors, their sequences have been compared with known protei...
متن کاملSynergistic activation of transcription by Escherichia coli cAMP receptor protein.
Activation of gene expression in eukaryotes generally involves the action of multiple transcription factors that function synergistically when bound near a particular target gene. Such effects have been suggested to occur because multiple activators can interact simultaneously with one or more components of the basal transcription machinery. In prokaryotes, examples of synergistic effects on tr...
