The human unr gene encodes an 85 kDa protein which contains five cold shock domains (CSD). The capacity of Unr to interact in vitro with RNA and its intracellular localization suggest that Unr could be involved in some aspect of cytoplasmic mRNA metabolism. As a step towards identification of Unr mRNA targets, we investigated the RNA-binding specificity of(More)
Thyroid hormones (TH) are pleiotropic factors important for many developmental and physiological functions in vertebrates and particularly in amphibian metamorphosis. Their effects are mediated by two specific receptors (TRalpha and TRbeta), which are ligand-dependent transcription factors, members of the nuclear hormone receptor superfamily. Besides their(More)
Central and peripheral mechanisms modulate food intake and energy balance in mammals and the precise role of the type 1 cannabinoid receptor (CB1) in these processes is still being explored. Using the zebrafish, Danio rerio, we show that rimonabant, a CB1-specific antagonist with an EC(50) of 5.15 × 10(-8) m, decreases embryonic yolk sac reserve use. We(More)
The unr gene was identified as a transcription unit located immediately upstream of N-ras in the genome of several mammalian species. While this genetic organization could be important for the transcriptional regulation of unr and N-ras, the function of the protein product of unr is unknown. unr is ubiquitously expressed and codes for an 85 kDa protein(More)
In mouse embryonic cells, ligand-activated retinoic acid receptors (RARs) play a key role in inhibiting pluripotency-maintaining genes and activating some major actors of cell differentiation. To investigate the mechanism underlying this dual regulation, we performed joint RAR/RXR ChIP-seq and mRNA-seq time series during the first 48 h of the RA-induced(More)
