摘要:Heterochromatin, defined by histone H3 lysine 9 methylation (H3K9me), spreads across large domains and can be epigenetically inherited in a self- propagating manner. Heterochromatin propagation depends upon a read-write mechanism, where the Clr4/ Suv39h methyltransferase binds to preexisting trimethylated H3K9 (H3K9me3) and further deposits H3K9me. How the parental methylated histone template is preserved during DNA replication is not well understood. Here, we demonstrate using Schizosaccharom...

摘要:Autosomal dominant polycystic kidney disease (ADPKD) is the most common mono-genic cause of chronic kidney disease and the fourth leading cause of end- stage kidney disease, accounting for over 50% of prevalent cases requiring renal replacement therapy. There is a pressing need for improved therapy for ADPKD. Recent insights into the pathophysiology of ADPKD revealed that cyst cells undergo metabolic changes that up- regulate aerobic glycolysis in lieu of mitochondrial respiration for energy p...

摘要:During auditory transduction, sound- evoked vibrations of the hair cell stereociliary bundles open mechanotransducer (MET) ion channels via tip links extending from one stereocilium to its neighbor. How tension in the tip link is delivered to the channel is not fully understood. The MET channel comprises a pore- forming subunit, transmembrane channel- like protein (TMC1 or TMC2), aided by several accessory proteins, including LHFPL5 (lipoma HMGIC fusion partner- like 5). We investigated the ro...

摘要:The warnings of potential climate migration first appeared in the scientific literature in the late 1970s when increased recognition that disintegrating ice sheets could drive people to migrate from coastal cities. Since that time, scientists have modeled potential climate migration without integrating other population processes, potentially obscuring the demographic amplification of this migration. Climate migration could amplify demographic change-enhancing migration to destinations and supp...

摘要:Assessing the ergodicity of graphene liquid cell electron microscope measurements, we report that loop states of circular DNA interconvert reversibly and that loop numbers fol-low the Boltzmann distribution expected for this molecule in bulk solution, provided that the electron dose is low (80- keV electron energy and electron dose rate 1-20 e(-) angstrom(-2) s(-1)). This imaging technique appears to act as a slow motion camera that reveals equilibrated distributions by imaging the time averag...

摘要:The ability to concisely describe the dynamical behavior of soft materials through closed-form constitutive relations holds the key to accelerated and informed design materials and processes. The conventional approach is to construct constitutive relations through simplifying assumptions and approximating the time-and rate dependent stress response of a complex fluid to an imposed deformation. While traditional frameworks have been foundational to our current understanding of soft materials, t...

摘要:Converting hydrocarbons and greenhouse gases (i.e., carbon dioxide, CO2) directly into electricity through fuel cells at intermediate temperatures (450 to 550(degrees)C) remains a significant challenge, primarily due to the sluggish activation of C-H and C=O bonds. Here, we demonstrated a unique strategy to address this issue, in which light illumination was introduced into the thermal catalytic CO2 reforming of ethane in the anode as a unique thermo-photo anode process for carbonate- superstr...

摘要:Red blood cell (RBC) metabolic reprogramming upon exposure to high altitude contributes to physiological human adaptations to hypoxia, a multifaceted process critical to health and disease. To delve into the molecular underpinnings of this phenomenon, first, we performed a multi- omics analysis of RBCs from six lowlanders after exposure to high- altitude hypoxia, with longitudinal sampling at baseline, upon ascent to 5,100 m and descent to sea level. Results highlighted an association between ...

摘要:How the human cortex integrates (binds) information encoded by spatially distributed neurons remains largely unknown. One hypothesis suggests that synchronous bursts of high- frequency oscillations (ripples) contribute to binding by facilitating integration of neuronal firing across different cortical locations. While studies have demonstrated that ripples modulate local activity in the cortex, it is not known whether their co- occurrence coordinates neural firing across larger distances. We t...
