Operando TEM Study of Partial Oxidation of Methane Over Pd Nanoparticles

open access: yesAdvanced Science, EarlyView.
This operando TEM study reveals that Pd nanoparticles (NPs) catalyze the partial oxidation of methane (POM) by transforming into smaller, highly dynamic mixed‐phase Pd–PdO NPs, with active sites located at the interface between the two phases. Here, metallic Pd facilitates CH4 dehydrogenation, while PdO promotes C oxidation.

BHLHE40 Cooperates with GATA2/3 to Control Human Syncytiotrophoblast Lineage Differentiation

open access: yesAdvanced Science, EarlyView.
BHLHE40 interacts directly with GATA2 and GATA3 and co‐occupies genomic loci critical for STB differentiation and function. BHLHE40 also affects GATA2/3 binding at enhancer and promoter regions. Moreover, BHLHE40 is potentially involved in genome‐wide remodeling of H3K4me3 and H3K27ac chromatin landscapes through GATA2/3 recruitment, activating ...

Alternative Models for Anticancer Drug Discovery From Natural Products Using Binary Tumor‐Microenvironment‐on‐a‐Chip

open access: yesAdvanced Science, EarlyView.
This study presents a binary tumor‐microenvironment‐on‐a‐chip (T‐MOC) system incorporating multicellular tumor spheroids (MCTs) as an alternative preclinical platform to evaluate the efficacy of anticancer natural products. The T‐MOC model reproduces in vivo drug delivery barriers and physiological conditions, enabling morphological analysis to predict

Synergistic Promotion of Triple‐Negative Breast Cancer Tumorigenesis and Metastasis by Oral Polystyrene Nanoplastics Exposure via Alloprevotella‐Derived Glutamate and Platelet Activation

open access: yesAdvanced Science, EarlyView.
Polystyrene nanoplastics (PS‐NPs) administered via oral exposure accelerate triple‐negative breast cancer (TNBC) progression by synergistically modulating gut microbiota‐derived glutamate production and platelet activation. This study uncovers a pivotal crosstalk between microbial metabolites and platelet‐tumor interactions, offering mechanistic ...
