Extensive Transcript Diversity and Novel Upstream Open Reading Frame Regulation in Yeast
To understand the diversity of transcripts in yeast (Saccharomyces cerevisiae) we analyzed the transcriptional landscapes for cells grown under 18 different environmental conditions. Each sample was analyzed using RNA-sequencing, and a total of 670,446,084 uniquely mapped reads and 377,263 poly-adenylated end tags were produced. Consistent with previous studies, we find that the majority of yea...
متن کاملSURVEY AND SUMMARY A profusion of upstream open reading frame mechanisms in polyamine-responsive translational regulation
In many eukaryotic mRNAs one or more short ‘upstream’ open reading frames, uORFs, precede the initiator of the main coding sequence. Upstream ORFs are functionally diverse as illustrated by their variety of features in polyamine pathway biosynthetic mRNAs. Their propensity to act as sensors for regulatory circuits and to amplify the signals likely explains their occurrence in most polyamine pat...

متن کاملStress-sensitive regulation of IFRD1 mRNA decay is mediated by an upstream open reading frame.
In this report, we demonstrate that cellular stress regulates expression of IFRD1 by a post-transcriptional control mechanism. IFRD1 mRNA and protein are elevated in tunicamycin-treated human kidney epithelial cells via stabilization of the mRNA. IFRD1 mRNA instability in resting cells requires translation of an upstream open reading frame (ORF) that represses translation of the major ORF. Duri...
متن کاملTranslation of the human erythropoietin transcript is regulated by an upstream open reading frame in response to hypoxia.
Erythropoietin (EPO) is a key mediator hormone for hypoxic induction of erythropoiesis that also plays important nonhematopoietic functions. It has been shown that EPO gene expression regulation occurs at different levels, including transcription and mRNA stabilization. In this report, we show that expression of EPO is also regulated at the translational level by an upstream open reading frame ...
