Dual‐Gating Strategy: Ultrasound Activation of TRPV2 Channels and Borate‐Glass‐Induced Calcium Overload for Tumor Suppression

open access: yesAdvanced Science, EarlyView.
A novel strategy combining borate glass and ultrasound is proposed for the precise treatment of breast cancer. The locally delivered borate glass releases Ca2⁺ ions in situ, while ultrasound activates the highly expressed transient receptor potential vanilloid 2 channels in breast cancer cells. This synergistic effect induces specific calcium overload,

Mitigating Doxorubicin‐Induced Cardiotoxicity and Enhancing Anti‐Tumor Efficacy with a Metformin‐Integrated Self‐Assembled Nanomedicine

open access: yesAdvanced Science, EarlyView.
A novel self‐assembled nanomedicine (PMDDH) has been developed for the co‐delivery of doxorubicin and metformin, aiming to enhance the anti‐tumor efficacy of doxorubicin while alleviating its cardiotoxicity through the activation of cGAS‐STING and AMPK signaling pathways, respectively.

Investigating electron conductivity regimes in the bacterial cytochrome wire OmcS [PDF]

open access: yesarXiv
The anaerobic bacterium \textit{Geobacter sulfurreducens} produces extracellular, electronically conductive cytochrome polymer wires that are conductive over micron length scales. Structure models from cryo-electron microscopy data show OmcS wires form a linear chain of hemes along the protein wire axis, which is proposed as the structural basis ...

Carbon Nanotubes as Intracellular Protein Transporters: Generality and Biological Functionality [PDF]

open access: yesarXiv, 2005
Various proteins adsorb spontaneously on the sidewalls of acid-oxidized single-walled carbon nanotubes. This simple non-specific binding scheme can be used to afford non-covalent protein-nanotube conjugates. The proteins are found to be readily transported inside various mammalian cells with nanotubes acting as the transporter via the endocytosis ...

High‐Throughput Proteoform Imaging for Revealing Spatial‐Resolved Changes in Brain Tissues Associated with Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
High‐throughput proteoform imaging (HTPi) is established by combining matrix‐assisted laser desorption ionization mass spectrometry imaging and high‐sensitivity region‐specific top‐down proteomic analysis. HTPi enables the generation of annotated proteoform images with exceptional precision, high throughput, and deep coverage, showing distinct spatial ...

Neophytadiene, a Plant Specialized Metabolite, Mediates the Virus‐Vector‐Plant Tripartite Interactions

open access: yesAdvanced Science, EarlyView.
Tomato chlorosis virus (ToCV) infection induces production of neophytadiene, a volatile resulting from chlorophyll degradation that is highly attractive to whiteflies. OBP2, an odorant‐binding protein from insect vector B. tabaci, exhibits a strong binding affinity for neophytadiene.

Probabilistic pairwise sequence alignment [PDF]

open access: yesarXiv, 2004
We describe an new algorithm for visualizing an alignment of biological sequences according to a probabilistic model of evolution. The resulting data array is readily interpreted by the human eye and amenable to digital image techniques. We present examples using mRNA sequences from mouse and rat: three cytochromes, Rattus norvegicus Cyp2a1, Cyp2a2 ...

Chromosome‐Level Genome Assembly of the Leafcutter Bee Megachile rotundata Reveals Its Ecological Adaptation and Pollination Biology

open access: yesAdvanced Science, EarlyView.
The genome of Megachile rotundata, an extensively managed solitary pollination bee species, has been sequenced, covering 280.68 Mb and predicting 10 701 genes. The study reveals significant expansions of the Toll gene family and their abundant expression in diapause prepupae, highlighting enhanced immune responses during diapause. This genome serves as

Ultrasound‐Responsive 4D Bioscaffold for Synergistic Sonopiezoelectric‐Gaseous Osteosarcoma Therapy and Enhanced Bone Regeneration

open access: yesAdvanced Science, EarlyView.
An acoustic‐responsive therapeutic platform for synergistic sonopiezoelectric‐gaseous osteosarcoma therapy and bone regeneration is fabricated through the joint loading of few‐layer black phosphorus nanosheets and S‐Nitroso‐L‐glutathione onto the 3D‐printed bioactive glass scaffolds.

Prediction of Cytochrome P450-Mediated Metabolism Using a Combination of QSAR Derived Reactivity and Induced Fit Docking [PDF]

open access: yesarXiv, 2018
Prediction of metabolism in cytochrome P450s remains to be a crucial yet challenging topic in discovering and designing drugs, agrochemicals and nutritional supplements. The problem is challenging because the rate of P450 metabolism depends upon both the intrinsic chemical reactivity of the site and the protein-ligand geometry that is energetically ...
