The DMA-1/LRR-TM cell surface receptor signals through partially redundant pathways to cell-autonomously pattern dendrites, including by directly forming a complex with both the TIAM-1/GEF and ACT-4/Actin.
Following fertilization, the pioneering transcription factors GAGA factor (GAF) and Zelda are independently required to reprogram the zygotic genome of Drosophila and activate the first wave of gene expression.
Plasticity arising from autocatalytic receptor activation coexists with robustness in ligand responsiveness only by differential endosomal sorting of spontaneous and ligand-activated EGFR as distinct molecular states.
Transcriptomic analysis using a novel information-based network entropy approach provides mechanistic insights into the ability of Klotho to successfully ameliorate age-related sarcopenia in old mice, but not oldest-old mice.
The ZF-CxxC protein FBXL19 recruits kinase-associated Mediator to CpG islands of silent developmental genes in embryonic stem cells, which primes these genes for activation during differentiation and is required for embryonic development.
Sox2 transcription is not correlated with spatial proximity of its essential regulatory enhancer in embryonic stem cells, suggesting gene transcription is not limited to periods of direct enhancer-promoter contact.
