Wearable Sensors for Plants: Status and Prospects.

The increasing demand for smart agriculture has led to the development of agricultural sensor technology. Wearable sensors show great potential for monitoring the physiological and surrounding environmental information for plants due to their high flexibility, biocompatibility, and scalability. However, wearable sensors for plants face several challenges that hinder their large-scale practical application.

Proximity Labeling-Based Identification of MGAT3 Substrates and Revelation of the Tumor-Suppressive Role of Bisecting GlcNAc in Breast Cancer via GLA Degradation.

Glycosylation plays a critical role in various biological processes, yet identifying specific glycosyltransferase substrates remains a challenge due to the complexity of glycosylation. Here, we employ proximity labeling with biotin ligases BASU and TurboID to map the proximitome of MGAT3, a glycosyltransferase responsible for the biosynthesis of the bisecting GlcNAc structure, in HEK293T cells. This approach enriched 116 and 189 proteins, respectively, identifying 17 common substrates shared with bisecting GlcNAc-bearing proteome obtained via intact glycopeptide enrichment methods.

O-GlcNAcylated FTO promotes m6A modification of SOX4 to enhance MDS/AML cell proliferation.

Fat mass and obesity-associated protein (FTO) was the first m6A demethylase identified, which is responsible for eliminating m6A modifications in target RNAs. While it is well-established that numerous cytosolic and nuclear proteins undergo O-GlcNAcylation, the possibility of FTO being O-GlcNAcylated and its functional implications remain unclear. This study found that a negative correlation between FTO expression and O-GlcNAcylation in patients with myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML).

An injectable nanocomposite hydrogel with deep penetration ability for enhanced photothermal and chemotherapy.

The excessive extracellular matrix (ECM) in solid tumors significantly inhibits the deep penetration and homogeneous distribution of nanodrugs, which greatly reduces the therapeutic efficacy. In the present work, an injectable polyelectrolyte hydrogel (CD@IPH) containing collagenase and doxorubicin-loaded polyacrylic acid@polyaniline nanoparticles (DOX@NP) were developed for improved photothermal and chemotherapy. The collagenase is released quickly from the polyelectrolyte hydrogel in the first 12 h, effectively degrading ECM and enhancing the deep penetration and evenly distribution of DOX@NP in tumor tissues.

Association Between Triglyceride-Glucose Index and Carotid Plaque Stability in Different Glycemic Status: A Single-Center Retrospective Study.

Background: The triglyceride-glucose (TyG) index has been proposed as a reliable marker of insulin resistance. However, its value in patients with carotid plaque stability remains unclear. This study investigated the association between the TyG index and unstable carotid plaque.
