摘要:Successful CRISPR/Cas9- based gene editing in skeletal muscle is dependent on efficient propagation of Cas9 to all myonuclei in the myofiber. However, nuclear- targeted gene therapy cargos are strongly restricted to their myonuclear domain of origin. By screening nuclear localization signals and nuclear export signals, we identify Myospreader, a combination of short peptide sequences that promotes myonuclear propagation. Appending Myospreader to Cas9 enhances protein stability and myonuclear p...

摘要:Reconstructing the absolute chronology of Jerusalem during the time it served as the Judahite Kingdom's capital is challenging due to its dense, still inhabited urban nature and the plateau shape of the radiocarbon calibration curve during part of this period. We present 103 radiocarbon dates from reliable archaeological contexts in five excavation areas of Iron Age Jerusalem, which tie between archaeology and biblical history. We exploit Jerusalem's rich past, including textual evidence and v...

摘要:How accurate are Americans' perceptions of the material benefits associated with union membership, and do these perceptions influence their support for, and interest in joining, unions? We explore these questions in a preregistered, survey experiment conducted on a national sample, representative of the US population on a number of demographic benchmarks ( n = 1,430). We find that Americans exhibit large and consistent underestimates of the benefits associated with unionization, as compared to...

摘要:Recent work finds that nonviolent resistance by ethnic minorities is perceived as more violent and requiring more policing than identical resistance by ethnic majorities, reducing its impact and effectiveness. We ask whether allies-advantaged group participants in disadvantaged group movements-can mitigate these barriers. On the one hand, allies can counter negative stereotypes and defuse threat perceptions among advantaged group members, while raising expectations of success and lowering expe...

摘要:Fluorescence labeling of chemically fixed specimens, especially immunolabeling, plays a vital role in superresolution imaging as it offers a convenient way to visualize cellular structures like mitochondria or the distribution of biomolecules with high detail. Despite the development of various distinct probes that enable superresolved stimulated emission depletion (STED) imaging of mitochondria in live cells, most of these membrane - potential - dependent fluorophores cannot be retained well ...

摘要:The IL- 17 pathway displays remarkably diverse functional modes between different subphyla, classes, and even orders, yet its driving factors remains elusive. Here, we demonstrate that the IL- 17 pathway originated through domain shuffling between a Toll- like receptor (TLR)/IL- 1R pathway and a neurotrophin- RTK (receptor- tyrosine- kinase) pathway (a Trunk- Torso pathway). Unlike other new pathways that evolve independently, the IL- 17 pathway remains intertwined with its donor pathways thro...

摘要:Cells must replicate their genome quickly and accurately, and they require metabolites and cofactors to do so. Ionic zinc (Zn 2+ ) is an essential micronutrient that is required for hundreds of cellular processes, including DNA synthesis and adequate proliferation. Deficiency in this micronutrient impairs DNA synthesis and inhibits proliferation, but the mechanism is unknown. Using fluorescent reporters to track single cells via long - term live - cell imaging, we find that Zn 2+ is required a...

摘要:Snakebite envenoming is a neglected tropical disease that causes substantial mortality and morbidity globally. The venom of African spitting cobras often causes permanent injury via tissue - destructive dermonecrosis at the bite site, which is ineffectively treated by current antivenoms. To address this therapeutic gap, we identified the etiological venom toxins in Naja nigricollis venom responsible for causing local dermonecrosis. While cytotoxic three - finger toxins were primarily responsib...

摘要:How breathing is generated by the preB & ouml;tzinger complex (preB & ouml;tC) remains divided between two ideological frameworks, and a persistent sodium current (I NaP ) lies at the heart of this debate. Although I NaP is widely expressed, the pacemaker hypothesis considers it essential because it endows a small subset of neurons with intrinsic bursting or pacemaker activity. In contrast, burstlet theory considers I NaP dispensable because rhythm emerges from preinspiratory spiking activity ...

摘要:Growth is a function of the net accrual of resources by an organism. Energy and elemental contents of organisms are dynamically linked through their uptake and allocation to biomass production, yet we lack a full understanding of how these dynamics regulate growth rate. Here, we develop a multivariate imbalance framework, the growth efficiency hypothesis, linking organismal resource contents to growth and metabolic use efficiencies, and demonstrate its effectiveness in predicting consumer grow...
