A developmental transcriptomics resource from Drosophila flight muscles quantifies the transcriptional dynamics during muscle morphogenesis and identifies three ordered phases of sarcomere morphogenesis.
Making a link between deletion of transcription cis-regulatory elements by CrispR/Cas9, obtention of mutants with single muscle morphology defects and their impact on locomotion.
Acting in neuronal stem cells, temporal transcription factors, as a class of molecules, are uniquely potent determinants of circuit membership that establish expected patterns of wiring in the motor system.

Genetic and biochemical evidence shows that the basal transcription machinery of muscle cells invariably relies on TBP/TFIID because TBP2 is not expressed in muscle cells, and thus resolves a longstanding issue raised by previous conflicting data.

Atrophic muscles of patients and animal models developing amyotrophic lateral sclerosis show an upregulation of TAp63 that stimulates the expression of a pro-atrophic ubiquitin ligase.

ATAC-seq, CRISPR/Cas9 mutagenesis, reporter and gene expression assays revealed dynamic chromatin accessibility profiles governing differential gene expression during heart vs. pharyngeal muscle fate choices in the powerful chordate model Ciona.
The regulatory programs governing skeletal muscle regeneration that are controlled by Klf5 in cooperation with MyoD and Mef2 provide a potential avenue for intervention into muscle regeneration through modulation of Klf5.
