Brain‐Penetrating and Disease Site‐Targeting Manganese Dioxide‐Polymer‐Lipid Hybrid Nanoparticles Remodel Microenvironment of Alzheimer's Disease by Regulating Multiple Pathological Pathways

Abstract Finding effective disease‐modifying treatment for Alzheimer's disease remains challenging due to an array of factors contributing to the loss of neural function. The current study demonstrates a new strategy, using multitargeted bi...

The Atr-Chek1 pathway inhibits axon regeneration in response to Piezo-dependent mechanosensation

The Atr-Check1 pathway is involved in cell cycle and the DNA damage response. Here, the authors show that the Atr-Check1 pathway can inhibit axon regeneration in response to Piezo-mediated mechanosensation, affecting functional recovery....

Structural basis for COMPASS recognition of an H2B-ubiquitinated nucleosome

Methylation of histone H3K4 is a hallmark of actively transcribed genes that depends on mono-ubiquitination of histone H2B (H2B-Ub). H3K4 methylation in yeast is catalyzed by Set1, the methyltransferase subunit of COMPASS. We report here th...

Involvement of two uptake mechanisms of gold and iron oxide nanoparticles in a co-exposure scenario using mouse macrophages

Little is known about the simultaneous uptake of different engineered nanoparticle types, as it can be expected in our daily life. In order to test such co-exposure effects, murine macrophages (J774A.1 cell line) were incubated with gold (A...

tRNA sequences can assemble into a replicator

Can replication and translation emerge in a single mechanism via self-assembly? The key molecule, transfer RNA (tRNA), is one of the most ancient molecules and contains the genetic code. Our experiments show how a pool of oligonucleotides, ...

Cryo-EM structures reveal how phosphate release from Arp3 weakens actin filament branches formed by Arp2/3 complex

Abstract Arp2/3 complex nucleates branched actin filaments for cell and organelle movements. Here we report a 2.7 Å resolution cryo-EM structure of the mature branch junction formed by S. pombe Arp2/3 complex that provides details about int...

The ZZ domain of HERC2 is a receptor of arginylated substrates

Abstract The E3 ubiquitin ligase HERC2 has been linked to neurological diseases and cancer, however it remains a poorly characterized human protein. Here, we show that the ZZ domain of HERC2 (HERC2ZZ) recognizes a mimetic of the Nt-R cargo ...

In vivo topology converts competition for cell-matrix adhesion into directional migration

Migrating cells encounter multiple signals such as extracellular matrix (ECM) and chemokinetic factors but how these integrate in vivo is unclear. Here, the authors report that overall control of cell-ECM adhesion by Sema3A and Sdf1 can be ...

Kinetic sculpting of the seven stripes of the Drosophila even-skipped gene

We used live imaging to visualize the transcriptional dynamics of the Drosophila melanogaster even-skipped gene at single-cell and high-temporal resolution as its seven stripe expression pattern forms, and developed tools to characterize an...

Encapsulated actomyosin patterns drive cell-like membrane shape changes

Summary: Cell shape changes from locomotion to cytokinesis are, to a large extent, driven by myosin-driven remodeling of cortical actin patterns. Passive crosslinkers such as α-actinin and fascin as well as actin nucleator Arp2/3 complex la...

Clinical evaluation of DIAGNOVIR SARS-CoV-2 ultra-rapid antigen test performance compared to PCR-based testing

Abstract Coronavirus Disease-19 (COVID-19) is a highly contagious infectious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The development of rapid antigen tests has contributed to easing the burden on ...

An integrated analysis of multiple datasets reveals novel gene signatures in human granulosa cells

Abstract Granulosa cells (GCs) play crucial roles in oocyte maturation. Through gap junctions and extracellular vesicles, they mediate the exchange of molecules such as microRNAs and messenger RNAs. Different ovarian cell types exhibit uniq...

RNA-seq analysis of gene expression profiles in isolated stria vascularis from wild-type and Alport mice reveals key pathways underling Alport strial pathogenesis.

Previous work demonstrates that the hearing loss in Alport mice is caused by defects in the stria vascularis. As the animals age, progressive thickening of strial capillary basement membranes (SCBMs) occurs associated with elevated levels o...

Atorvastatin suppresses high-risk colorectal adenomas via reprogramming of lipid metabolism and Inhibition of stemness

Abstract As critical precursors to colorectal cancer (CRC), high-risk colorectal adenomas (HR-CRAs) lack effective chemopreventive strategies beyond endoscopic resection. We previously established a standardized protocol for culturing patie...

Investigating the performance of the fluorescent sensor g-C3N4/Fe/Cu in detecting the Tenofovir drug

Abstract Tenofovir is an antiviral drug that prevents the replication of AIDS and hepatitis B viruses. To minimize the harmful side effects of the drug on the body, it is essential to determine its precise concentration in the blood. Fluore...

Synthesis of 9-arylalkynyl- and 9-aryl-substituted benzo[b]quinolizinium derivatives by Palladium-mediated cross-coupling reactions

9-Arylbenzo[b]quinolizinium derivatives were prepared with base-free Suzuki–Miyaura coupling reactions between benzo[b]quinolizinium-9-trifluoroborate and selected benzenediazonium salts. In addition, the Sonogashira coupling reaction betwe...

3D Printing parameter optimisation combined with heat treatment for achieving high density and enhanced performance in refractory high-entropy alloys

In this study, a Ti1.5Nb1Ta0.5Zr1Mo0.5 (TNTZM) high-entropy alloy was fabricated using laser powder bed fusion (LPBF). By integrating 63 sets of parameter trials with machine learning (ML) models, an optimised process window was identified,...
