Cell lineage tracing and biochemical analysis of cell fate during murine stem cell differentiation demonstrates a specific cooperativity between perturbations in histone methylation and eroded telomeres that destabilize cell differentiation.
Pathological vessel leakage in mouse retinopathy models depends on VE-cadherin Y685 phosphorylation status, which in turn is regulated by a signaling cascade originating with VEGFR2 Y949 phosphorylation.
In vertebrates, large regulatory landscapes sometimes behave as coherent regulatory units, which may explain the lack of effect sometimes observed when single enhancer sequences are deleted in isolation.
In mouse brain slices, native delta glutamate receptors carry ionic current and underlie the α1-adrenergic receptor-mediated depolarization of dorsal raphe neurons that drives action potential firing in vivo.
Single-cell RNA-sequencing resolves the transcriptional landscape of asexual development in Toxoplasma gondii, revealing concerted genetic programs to Plasmodiumfalciparum and a novel transcriptional factor that controls antigen switching.
