    Through drug exposure, a rare, transient transcriptional program characterized by high levels of expression of known resistance drivers can get ‘burned in’, leading to the selection of cells endowed with a transcriptional drug resistance and thus more chemoresistant cancers.

    Many gene-regulatory proteins have been shown to activate in pulses, but whether cells exploit the dynamic interaction between pulses of different regulatory proteins has remained unexplored; here single-cell videos show that yeast cells modulate the relative timing between the pulsatile transcription factors Msn2 and Mig1—a gene activator and a repressor, respectively—to control the expression of target genes in response to diverse environmental conditions.

    Little is known about how individual cells within a group of cells exposed to the same external signals can produce a specific individual response to their local microenvironment; a quantitative analysis of cell crowding reveals that single cells can autonomously sense local crowding though their ability to spread and activate focal adhesion kinase (FAK), which ultimately results in changes in cellular lipid composition.

    This study uses single-cell expression profiling of pluripotent stem cells after various perturbations, and uncovers a high degree of variability that can be inherited through cell divisions—modulating microRNA or external signalling pathways induces a ground state with reduced gene expression heterogeneity and a distinct chromatin profile.

    Single-cell RNA sequencing is used to investigate the transcriptional response of 18 mouse bone-marrow-derived dendritic cells after lipopolysaccharide stimulation; many highly expressed genes, such as key immune genes and cytokines, show bimodal variation in both transcript abundance and splicing patterns. This variation reflects differences in both cell state and usage of an interferon-driven pathway involving Stat2 and Irf7.
