3D niche topology imposes a spatially biased random stem cell loss, which is differentially fine-tuned in neural retina and retinal pigmented epithelium to regulate growth, shape, and cellular topology.
Unique heterochrony in the cranial segments in bichirs triggers the early formation of their external gills, and might be informative about developmental mechanisms facilitating increased breathing capacity.
A single neonatal inflammatory event induces long-term impairments in two forms of adult respiratory motor plasticity, an important aspect of the control of breathing for compensation after injury or disease.
TBX5-loss associated cardiomyocyte ectopy and atrial fibrillation is prevented by augmentation of SERCA2 activity, establishing a mechanism underlying the genetic basis for a Ca2+-dependent pathway for AF risk.
mille-pattes micropeptides have conserved function in insect embryonic patterning together with transcription factor Shaven-baby and ubiquitin ligase Ubr3, except in flies wherein restoring broad embryonic Svb expression restores patterning potency.
OptoGranules reveal the function of G3BP1 as a stress granule scaffold and demonstrate that protracted stress granule assembly is sufficient to drive neurodegeneration and the evolution of ALS-FTD pathology.
Natural step-to-step variations show how human running is stabilized, underscoring the importance of center of mass control and showing how humans run without falling despite muscle noise and uneven terrain.
The budding yeast transcription factors Reb1 and Cbf1 function as pioneer factors by slowly dissociating from nucleosomes, allowing them to target and unwrap nucleosomes efficiently to regulate transcription.
A direct relationship between pupil diameter and electrophysiological correlates of attention, sensory stimulus processing and target detection was observed demonstrating that arousal has a substantial influence on perceptual decision-making.
Subtypes of dendrite-targeting somatostatin cells segregate into separate networks by specifically connecting with neurons in different layers, forming circuits that could independently control different input pathways to the neocortex.
Activation of a piRNA cluster is achieved by high temperature and without maternal inheritance of homologous piRNAs highlighting how variations of species natural habitat can become heritable and shape epigenome.
The extent of (proteotoxic) endoplasmic reticulum stress, and the ensuing unfolded protein response activation, are commensurate with the extent of the chaperone BiP being sequestered by its client proteins.
Empirical evaluations demonstrate the low probability of finding and replicating significant associations between psychological tests and brain structure in healthy adults, highlighting the importance out-of-sample replication of exploratory findings.
The pro-apoptotic BH3-protein Bim contains two distinct binding sites for anti-apoptotic proteins that together confer resistance of Bim/Bcl-2 and Bim/Bcl-XL complexes to BH3-mimetic drugs under development for use in humans.
A multipartite virus functionally spreads its distinct genome segments in distinct individual cells of the host plant, and complementation of the viral genes across cells allows a pluricellular infection cycle.
Faithful models of RMC require SMARCB1 loss for survival, and genetic and small-molecule screens identify inhibition of the ubiquitin-proteasome system (UPS) as a potential therapeutic approach for SMARCB1 deficient cancers.
Epidermal cells in vertebrates and invertebrates ensheath portions of somatosensory neurons via a conserved morphogenetic mechanism, and this ensheathment regulates morphogenesis and function of Drosophila nociceptive neurons.
A 3D model captures the growth and expansion dynamics of bacterial colonies, revealing distinct effects of surface tension, mechanical forces, and nutrients on the speed of radial and vertical expansion.
