Site-specific protein multi-conjugates are important for both scientific and translational research. Here, the authors genetically encode unnatural amino acids which contain both tetrazine and azide, and use the doubly bio-orthogonal handles to generate bi- and tri-conjugate proteins in high yields.
Immobilization of biomolecules into porous materials could lead to enhanced performance in terms of stability and easier separation for their reuse. Here authors gain insights into the spatial arrangement of green fluorescent protein entrapped in a mesoporous MOF by situ small-angle neutron scattering.
Delivery of anti-inflammatory microRNA (miRNA) could be beneficial for inflammatory diseases such as rheumatoid arthritis (RA). Here the authors show that a fluorinated polyamidoamine dendrimer nanoparticle delivers miR-23b to affected RA joints and reduces inflammation, joint damage and synovial cell influx.
Bhardwaj et al., have explored the proteomes of SARS-CoV and SARS-CoV-2, and have demonstrated the amyloid formation of viral proteins, in vitro, through diverse biophysical techniques.
Light interaction with atoms depends on the strength of the light-matter coupling and the energy splitting of the modes involved. Here the authors study of quantum Rabi dynamics in a deep strong coupling regime by using a cloud of cold rubidium atoms.
Non-coding transcription at the intergenic regulatory regions is a prevalent feature of metazoan genomes, but its function remains uncertain. Here the authors show that enhancer function is flexibly tunable through the modulation of hub formation via surrounding non-coding transcription.
Here, the authors discover small molecules that inhibit glycosylation processes that occur in the Golgi apparatus of cells. The molecules reversibly inhibit formation of elaborate glycan structures without affecting secretion of glycoproteins.
The circulatory lipidome is a valuable source for disease markers, but reliable marker discovery requires continuous development of lipidomic methods for large-scale clinical profiling. Here, the authors present a 4-dimensional lipidomics solution for confident and reproducible blood lipidome profiling.
The current study identifies five genomic subclusters of brain regions for cortical thickness and surface area characterized by high levels of shared genetic signal. These subclusters map onto biological and functional parcellations of the cortex.
The blood-brain barrier represents a hurdle for the delivery of therapeutics in brain tumor tissues. Here the authors describe the design of a nitric oxide-driven nanomotor loaded with the glycolysis inhibitor lonidamine, breaking through the blood-brain barrier and eliciting anti-tumor immune responses in preclinical models of glioblastoma.
Mutations of ATRX are frequent in cancers that immortalize through the ALT (Alternative lengthening of telomeres) pathway. Here the authors show that ALT features are repressed in embryonic stem cells that lack ATRX but induced by continuous telomere instability triggered upon cell differentiation.
Delineating the cellular composition of tumour boundaries in spatial transcriptomics (ST) data is challenging. Here, the authors develop Cottrazm to integrate ST with histological imaging and single-cell data, identify the malignant and non-malignant tissue boundaries, deconvolute cell-type composition, and reconstruct cell type-specific gene expression profiles.
Here the authors investigate a comprehensive topological phase diagram of bilayer hexagonal acoustic lattice, including ideal quantum spin Hall phase with gapless helical edge states. They realize a broadband topological slow wave.
Reactive oxygen species (ROS) are present in the pore water of intertidal permeable sediments, even in the anoxic zones. They control aerobic and anaerobic microbial degradation processes and thereby impact carbon turnover.
Why fluid and solute transport in perivascular spaces is enhanced upon sleep remains elusive. Here, the authors show that each sleep cycle state displays unique perivascular dynamics, which enhances predicted fluid movement and solute transport.
Populations of swarming coupled oscillators with inhomogeneous natural frequencies and chirality are relevant for active matter systems and micro-robotics. The authors model and analyze a variety of their self-organized behaviors that mimic natural and artificial micro-scale collective systems.
The most widely used density functional approximations for heterogenous catalysis has limited accuracy. Here, the authors propose a hybrid scheme to accurately describe Cu surface for CO2 electroreduction, facilitating the rational design of catalysts.
Allogeneic iPSC-derived cartilage organoids survive and integrate with surrounding native cartilage without immune reactions in a primate model of chondral defects in the knee joints, being remodeled and functioning as articular cartilage.
Mechanisms underlying sleep dysfunctions in neurodevelopmental disorders remain elusive. Here, authors use a fly model for the CYFIP haploinsufficiency to show that increased SREBP activity impairs the NADP+/NADPH homeostasis inducing sleep deficits.
