Parkinson's disease protein DJ-1 regulates ATP synthase protein components to increase neuronal process outgrowth
(Springer Nature, 2019-06-13)Familial Parkinson’s disease (PD) protein DJ-1 mutations are linked to early onset PD. We have found that DJ-1 binds directly to the F1FO ATP synthase β subunit. DJ-1’s interaction with the β subunit decreased mitochondrial ... -
Single nucleosome imaging reveals loose genome chromatin networks via active RNA polymerase II.
(Rockefeller University Press, 2019-03-01)Although chromatin organization and dynamics play a critical role in gene transcription, how they interplay remains unclear. To approach this issue, we investigated genome-wide chromatin behavior under various transcriptional ... -
Xenopus resources: Transgenic, inbred and mutant animals, training opportunities, and web-based support.
(Frontiers Media, 2019-04-25)Two species of the clawed frog family, Xenopus laevis and X. tropicalis, are widely used as tools to investigate both normal and disease-state biochemistry, genetics, cell biology, and developmental biology. To support ... -
A ctenophore (comb jelly) employs vortex rebound dynamics and outperforms other gelatinous swimmers
(The Royal Society, 2019-03-20)Gelatinous zooplankton exhibit a wide range of propulsive swimming modes. One of the most energetically efficient is the rowing behaviour exhibited by many species of schyphomedusae, which employ vortex interactions to ... -
Seasonal and daily patterns of the mating calls of the oyster toadfish, Opsanus tau.
(University of Chicago Press, 2019-02-08)Acoustic communication is vital across many taxa for mating behavior, defense, and social interactions. Male oyster toadfish, Opsanus tau, produce courtship calls, or “boatwhistles,” characterized by an initial broadband ... -
Climate and lawn management interact to control C4 plant distribution in residential lawns across seven U.S. cities.
(Ecological Society of America, 2019-04-01)In natural grasslands, C4 plant dominance increases with growing season temperatures and reflects distinct differences in plant growth rates and water use efficiencies of C3 vs. C4 photosynthetic pathways. However, in ... -
Water salinity and inundation control soil carbon decomposition during salt marsh restoration: An incubation experiment.
(Wiley Open Access, 2019-02-10)Coastal wetlands are a significant carbon (C) sink since they store carbon in anoxic soils. This ecosystem service is impacted by hydrologic alteration and management of these coastal habitats. Efforts to restore tidal ... -
AP-1cFos/JunB/miR-200a regulate the pro-regenerative glial cell response during axolotl spinal cord regeneration
(Nature Research, 2019-03-06)Salamanders have the remarkable ability to functionally regenerate after spinal cord transection. In response to injury, GFAP+ glial cells in the axolotl spinal cord proliferate and migrate to replace the missing neural ... -
Understanding regeneration at different scales.
(eLife Sciences Publications, 2019-03-13)Regeneration occurs at many different levels in nature, from individual organisms (notably earthworms and hydra), through communities of microbes, to ecosystems such as forests. Researchers in the life sciences and the ... -
Dynamic pigmentary and structural coloration within cephalopod chromatophore organs
(Nature Research, 2019-03-01)Chromatophore organs in cephalopod skin are known to produce ultra-fast changes in appearance for camouflage and communication. Light-scattering pigment granules within chromatocytes have been presumed to be the sole source ... -
Colloid osmotic parameterization and measurement of subcellular crowding
(American Society for Cell Biology, 2019-01-14)Crowding of the subcellular environment by macromolecules is thought to promote protein aggregation and phase separation. A challenge is how to parameterize the degree of crowding of the cell interior or artificial solutions ... -
Localizing individual soniferous fish using passive acoustic monitoring
(Elsevier, 2018-08-13)Identifying where fish inhabit is a fundamentally important topic in ecology and management allowing acoustically sensitive times and areas to be prioritized. Passive acoustic localization has the benefit of being a ... -
Propulsive design principles in a multi-jet siphonophore.
(Company of Biologists, 2019-02-27)Coordination of multiple propulsors can provide performance benefits in swimming organisms. Siphonophores are marine colonial organisms that orchestrate the motion of multiple swimming zooids for effective swimming. However, ... -
Drosophila kinesin-8 stabilizes the kinetochore–microtubule interaction
(Rockefeller University Press, 2018-12-11)Kinesin-8 is required for proper chromosome alignment in a variety of animal and yeast cell types. However, it is unclear how this motor protein family controls chromosome alignment, as multiple biochemical activities, ... -
Elaborate pupils in skates may help camouflage the eye
(Company of Biologists, 2019-01-21)The skate Leucoraja erinacea is a bottom-dweller that buries into the substrate with its eyes protruding, revealing elaborately shaped pupils. It has been suggested that such pupil shapes may camouflage the eye, yet this ... -
An amphipathic helix enables septins to sense micrometer-scale membrane curvature
(Rockefeller University Press, 2019-01-18)Cell shape is well described by membrane curvature. Septins are filament-forming, GTP-binding proteins that assemble on positive, micrometer-scale curvatures. Here, we examine the molecular basis of curvature sensing by ... -
A versatile and open-source rapid LED switching system for one-photon imaging and photo-activation
(Frontiers Media, 2019-01-17)Combining fluorescence and transmitted light sources for microscopy is an invaluable method in cellular neuroscience to probe the molecular and cellular mechanisms of cells. This approach enables the targeted recording ... -
Lateral line sensitivity in free-swimming toadfish Opsanus tau
(Company of Biologists, 2019-01-25)A longstanding question in aquatic animal sensory physiology is the impact of self-generated movement on lateral line sensitivity. One hypothesis is that efferent modulation of the sensory hair cells cancels self-generated ... -
Regenerative capacity in the lamprey spinal cord is not altered after a repeated transection
(Public Library of Science, 2019-01-30)The resilience of regeneration in vertebrates is not very well understood. Yet understanding if tissues can regenerate after repeated insults, and identifying limitations, is important for elucidating the underlying ... -
Effect of continuous light on leaf wax isotope ratios in Betula nana and Eriophorum vaginatum: Implications for Arctic paleoclimate reconstructions
(Elsevier B.V., 2018-08-22)Reconstructions of climate using leaf wax D/H ratios (δDwax) require accounting for the apparent isotopic fractionation (εapp) between plant source water and waxes. There have been conflicting publications on whether plants ...
