"Cells integrate environmental signals and internal states to dynamically control gene expression. Muller et al. developed a technique to dissect this cellular logic by linking targeted, genome-wide genetic perturbations with a deep-sequencing readout that quantitatively measured the expression phenotype induced by each perturbation. The method, dubbed CiBER-seq, was able to recapitulate known regulatory pathways linking protein synthesis with nutrient availability in budding yeast cells. Unexpectedly, the authors found that the cellular logic also appears to consider protein production machinery in this decision. By uncovering additional facets of this deeply conserved pathway, the findings demonstrate the utility of comprehensive and quantitative CiBER-seq profiling in mapping the gene networks underlying cellular decisions."
