MetabolomicsTranslational repression of viral RNA mediates arbovirus persistence in mosquitoes

Persistent infection of mosquito vectors is essential for the transmission of arboviruses, yet how these viruses produce sufficient progeny without compromising host cell fitness remains unclear. Arbovirus genomes exhibit suboptimal codon usage for both human and mosquito hosts, raising questions...

MetabolomicsInositol Pyrophosphates Mediate Chloroplast Lipid Remodeling and Nuclear Gene Repression during High-Light Acclimation in Chlamydomonas reinhardtii
Microalgae are photosynthetic organisms capable of autotrophic growth. Their applicability in multiple industrial fields has been largely studied, thanks to their ability to fixate CO2 into high added value organic products like fatty acids and carotenoids. However, our under-standing of the cellula...

ModelsGlucose Repression Signaling 2009
Background In the yeast Saccharomyces cerevisiae, the presence of high levels of glucose leads to an array of down-regulatory effects known as glucose repression. This process is complex due to the presence of feedback loops and crosstalk between different pathways, complicating the use of intuitive...

TranscriptomicsTranscriptional response of steady-state Escherichia coli cultures to a glucose pulse, in order to elucidate the role of post-transcriptional regulation during carbon catabolite repression
Gene-expression measurements were made over a 60 minute time course as steady state E. coli cells were subjected to a pulse of glucose.

TranscriptomicsEstrogen-mediated Epigenetic Repression of Large Chromosomal Regions through DNA Looping
The current concept of epigenetic repression is based on one repressor unit corresponding to one silent gene. This notion, however, cannot adequately explain concurrent silencing of multiple loci observed in large chromosome regions. The long-range epigenetic silencing (LRES) can be a frequent occur...

TranscriptomicsA large intergenic non-coding RNA induced by p53 mediates global gene repression in the p53 transcriptional response
Recently, more than a thousand large intergenic non-coding RNAs (lincRNAs) have been reported. These RNAs are evolutionarily conserved in mammalian genomes and thus presumably function in diverse biological processes. Here, we report the identification of lincRNAs that are regulated by p53. One of ...

TranscriptomicsA network of transcriptional repression specifies muscle fibre type in the zebrafish embryo
The zebrafish u-boot (ubo) gene encodes the transcription factor Prdm1, which is essential for the specification of the primary slow twitch muscle fibres that derive from adaxial cells. Here we show that Prdm1 executes this function by acting as a transcriptional repressor. Expression of the slow tw...

TranscriptomicsCatabolite repression of phosphoenolpyruvate carboxykinase by a zinc finger protein under biotin- and pyruvate carboxylase-deficient conditions in Pichia pastoris
We have identified a methanol- and biotin-starvation-inducible zinc finger protein named ROP [repressor of phosphoenolpyruvate carboxykinase (PEPCK)] in the methylotrophic yeast Pichia pastoris. When P.pastoris strain GS115 (wild-type, WT) is cultured in biotin-deficient, glucose ammonium (Bio-) ...

GenomicsActivation and repression by oncogenic Myc shapes tumour-specific gene expression profiles
In mammalian cells, the Myc oncoprotein binds to thousands of promoters. During mitogenic stimulation of primary lymphocytes, Myc promotes an increase in expression of virtually all genes. In contrast, Myc-driven tumour cells differ from normal cells in expression of specific sets of up- and downreg...
