The molecular identity of bi-fated tendon-to-bone attachment cells, which display a mixture of transcriptomes of two neighboring cell types, enables the formation of the unique transitional tissue of the enthesis.

A fish-derived bile salt was shown to act as interspecific infochemical, inducing the widespread predator avoidance behavior diel vertical migration at picomolar concentrations in freshwater zooplankton of the genus Daphnia.
Single molecule FISH analysis defines the behavior of centromere-derived alpha-satellite transcripts in intact human cells and reveals a critical role for centromere-nucleolar contacts in repressing alpha-satellite transcription.

The regulation of gene expression can be either binary (on/off digital regulation) or graded (analog regulation) and these fundamentally different regulatory modes can be integrated to control the expression of the same gene.
Analyzing the readout of Notch signaling with single RNA precision reveals that active transcription sites are the most accurate measure of Notch-dependent transcriptional activation.

Steroid hormone receptors control the expression of their target genes through a digital on-off switch in individual cells, which leads to an analogue dose-response relationship at the level of the whole organism.
Transcription and epigenetic memory of transcription are two co-occurring independent pathways, governed by different rate constants and unique parameters.
Single-cell and single-molecule analyses of transient gene expression revealed hitherto unrecognized dynamics in heterochromatin function and defined novel roles for a heterochromatin establishment factor and an understudied sirtuin.

Mechanisms that regulate RNA localization in one cell type predictably regulate RNA localization in other cell types, even if they have vastly different morphologies, implying an underlying regulatory code that cuts across specific subcellular structures.
