Our translational and transcriptional profiling confirmed that ISRIB treatment of ER-stressed cells substantially and comprehensively blocks the translational effects of eIF2α phosphorylation.
In contrast to MAFP, which comprehensively blocks brain 2-AG hydrolySaarioaario et al. 2004), approx. 15% residual activity remained after maximally effective concentration of NAM (Saario et al. 2005).
Importantly, we show that ISRIB comprehensively blocks translational upregulation of the vast majority of the mRNAs in HEK293T cells, including the well-established ISR translational targets ATF4, ATF5, CHOP and GADD34.
The ribosome and mRNA genome-wide profiling data demonstrates that ISRIB comprehensively blocks the translational effects driven by UPR activation and eIF2α phosphorylation and does not lead to overall and spurious changes in mRNA levels or translation.
Moreover, ISRIB comprehensively and selectively blocked the effects of eIF2α phosphorylation on mRNA translation and triggered rapid stress granule disassembly (Sidrauski et al., 2015).
To comprehensively analyze the degradation rates of CCA1-LUC and TOC1-LUC throughout the circadian cycle, we blocked de novo protein synthesis using saturating concentrations [ 12] of cycloheximide (CHX) at 2 hr intervals in constant light (LL).
At an EU summit, Britain is likely to find itself comprehensively outvoted in its effort to block the appointment of Jean-Claude Juncker as the next president of the European Commission.
Three additional tests were administered in order to assess memory functions more comprehensively: the Corsi block-tapping test 27 and digit span test, 28 respectively, for visuospatial and verbal short-term memory, and the story recall test 27 for the evaluation of episodic memory.
No country forced its hand on emission cuts in the negotiations, and it was itself comprehensively split, with countries such as Poland and even Germany reportedly blocking moves by Britain and others to put the cuts on the table.
