A proteomics-based approach identifies novel substrate proteins of the Lon protease in Caulobacter crescentus and reveals a critical role of Lon in regulating flagella assembly and stalk biogenesis during the cell cycle.
Somatic stem and niche cells in the Drosophila ovary develop from common precursors through regulated proliferative expansion, followed by acquisition of position-specific behaviors, rather than through rigid early specification events.
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.
Lesions to the anterior-medio-dorsal thalamus cause widespread behavioral impairments across multiple cognitive domains, suggesting that thalamic hubs are critical for interconnecting diverse cognitive processes.
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.
