Modulation of muscle stem cell redox state in culture both improves their amplification while maintaining a similar grafting potential as freshly isolated stem cells.
Protein kinase A-driven increases in c-MYC protein expression and tumor cell proliferation can be blocked by eIF4A inhibitors, suggesting a potential new treatment option for patients with oncogenic PKA activation.

A Cre-dependent reporter mouse line is generated, validated, and used to map cell-type-specific proteome and phosphoproteome of corticostriatal projections across postnatal development.

eIF3, despite being a general translation initiation factor, functions in mRNA-specific regulation, having a profound impact on the synthesis and activation of the MAPK pathway components and ribosomal proteins.
CUT&RUN (Cleavage Under Targets & Release Using Nuclease) profiles antibody-targeted DNA-binding proteins in situ with high resolution and low background, providing a simple, robust and scalable alternative to chromatin immunoprecipitation.

Single-cell experiments and mathematical modelling show that cellular signalling networks are vulnerable to trade-offs in speed versus accuracy, but that these vulnerabilities can be overcome by distributing the two tasks to different, although interacting, subnetworks.

A near-complete flux balance analysis model of a minimal cell demonstrates the high essentiality of its metabolic genes, agrees well with experimental essentiality data and suggests some further gene removals.
