Integrin- and ERK signaling stimulates mammary epithelial cell proliferation when extracellular collagen condenses, causing asymmetric growth of multicellular aggregates that is necessary for elongation during branching morphogenesis.
Striatal cholinergic interneurons and astrocytes lose cilia and show dysregulation of Hedgehog signaling in mice with a Parkinson's disease-associated, G2019S LRRK2 mutation or upon loss of PPM1H phosphatase specific for LRRK2-phosphorylated Rab GTPases.
Data exploring host and parasite signatures in the peripheral blood indicate that total parasite biomass is a better predictor of P. vivax-induced host responses and pathogenesis than peripheral parasitemia.
Lineage tracing and genetic experiments resolve a long-standing controversy by showing that retinoic acid signaling is active in cardiomyocytes, both during development and after myocardial infarction, and protects damaged hearts from apoptosis.
Estimating fine-scale spatiotemporal patterns of Plasmodium falciparum transmission showed an association between entomological inoculation rate and parasite prevalence that emphasizes the value of both measures in malaria surveillance.
Quantitative FRET imaging in moving C. elegans shows that stretch-unfolding of twitchin kinase occurs in the active muscle, whereby mechanical activity titrates the signaling pathway of this cytoskeletal kinase.
Myogenin promotes centrosome attenuation and establishes the nuclear envelope as the dominant microtubule organization center via the scaffold protein AKAP6, which is required for the recruitment of centrosomal proteins.
