Novel cuprotosis-related gene signature: a prognostic indicator and regulator of the glioma immune microenvironment.

Background: Glioma is a primary malignant brain tumor with a poor prognosis. Glioma-related biomarkers need to be identified to enable the personalized treatment of and predict the prognosis of glioma patients. Cuproptosis is an unusual mechanism of cell death, and is closely associated with disease progression and the immune-microenvironment of the tumor.

Biomolecule-functionalized polydiacetylene assembly for visual and on-site sensing of (E)-2-hexenal in fruits.

(E)-2-Hexenal (E2H) is an important volatile organic compound (VOC) that can serve as a marker for fruit quality sensing and shelf-life evaluation. However, visual and portable sensors for E2H have not been reported mainly because of the difficulty in selective response to E2H while avoiding interference from other VOC, especially isomers. Herein, we developed a novel colorimetric sensor based on thiol-functionalized polydiacetylene assembly (PDA-SH/PDA) for the quantitative and selectivity of E2H.

Induction of ferroptosis of iridium(III) complexes localizing at the mitochondria and lysosome by photodynamic therapy.

In this study, [Ir(ppy)(DMHBT)](PF) (ppy = deprotonated 1-phenylpyridine, DMHBT = 10,12-dimethylpteridino[6,7-f][1,10]phenanthroline-11,13-(10,12H)-dione, 8a), [Ir(bzq)(DMHBT)](PF) (bzq = deprotonated benzo[h]quinoline, 8b) and [Ir(piq)(DMHBT)](PF) (piq = deprotonated 1-phenylisoquinoline, 8c) were synthesized and characterized by HRMS, C NMR and H NMR. In vitro cytotoxicity experiments showed that 8a, 8b, 8c show moderate cytotoxicity against B16 cells, while the cytotoxicity of the complexes 8a, 8b and 8c toward B16 cells was greatly improved upon light irradiation, which can be used as photosensitizers to exert anticancer efficacy in photodynamic therapy (PDT). After being taken up by cells, 8a, 8b, 8c were localized in the mitochondria, resulting in a large amount of Ca in-flux, a burst release of ROS, a sustained opening of mitochondrial permeability transition pore, and a decrease of the mitochondrial membrane potential, which led to mitochondrial dysfunction and further activation of caspase 3 and Bcl-2 family proteins to induce apoptosis.

S-Nitrosylation of NOTCH1 Regulates Mesenchymal Stem Cells Differentiation Into Hepatocyte-Like Cells by Inhibiting Notch Signalling Pathway.

The differentiation of mesenchymal stem cells (MSCs) into hepatocyte-like cells (HLCs) is considered one of the most promising strategies for alternative hepatocyte transplantation to treat end-stage liver disease. To advance this method, it is crucial to gain a deeper understanding of the mechanisms governing hepatogenic differentiation. The study demonstrated that suppression of the intracellular domain release of the Notch pathway receptor via the γ-secretase inhibitor N-[(3, 5-difluorophenyl)acetyl]-L-alanyl-2-phenylglycine-1, 1-dimethylethyl ester (DAPT) significantly promotes the expression of hepatocyte-related genes and proteins in HLCs.

Endothelial FUNDC1 Deficiency Drives Pulmonary Hypertension.

Background: Pulmonary hypertension (PH) is associated with endothelial dysfunction. However, the cause of endothelial dysfunction and its impact on PH remain incompletely understood. We aimed to investigate whether the hypoxia-inducible FUNDC1 (FUN14 domain-containing 1)-dependent mitophagy pathway underlies PH pathogenesis and progression.

Microbiome and metabolomics reveal the effect of gut microbiota on liver regeneration of fatty liver disease.

Background: Metabolic dysfunction-associated fatty liver disease (MAFLD) is associated with impaired regenerative capacity and poor postoperative prognosis following hepatectomy. Previous research has highlighted the importance of the gut-liver axis in the physiological and pathological processes of the liver. However, the contribution of gut bacteria to the regeneration of livers with MAFLD and its metabolic regulatory mechanisms remain elusive.

Microneedle Electrode Patch Modified with Graphene Oxide and Carbon Nanotubes for Continuous Uric Acid Monitoring and Diet Management in Hyperuricemia.

Hyperuricemia is a common disorder induced by purine metabolic abnormality, which will further cause chronic kidney disease, cardiovascular disease, and gout. Its main pathological characteristic is the high uric acid (UA) level in the blood, so that the detection of UA is highly important for hyperuricemia diagnosis and therapy. Herein, we report a biocompatible and minimally invasive microneedle electrode patch (MEP) for continuous UA monitoring and diet management in hyperuricemia.

Comparative analysis of the long-term efficacy and safety of minimally invasive simple prostatectomy and endoscopic enucleation of the prostate for large benign prostatic hyperplasia (>80 mL).

All-in-one multiple extracellular vesicle miRNA detection on a miniaturized digital microfluidic workstation.

Extracellular vesicles (EVs) and EV-derived microRNAs (EV-miRNAs) are emerging as promising circulating biomarkers for early detection of malignant tumors such as non-small cell lung cancer (NSCLC). However, utilization of the gold standard method of RNA detection, the reverse transcription - quantitative polymerase chain reaction (RT-qPCR), on EV-miRNAs is hindered by laborious sample purification requirements and time-consuming multi-step procedures. Herein, we propose and demonstrate a miniaturized digital microfluidic (DMF) workstation for all-in-one EV-miRNA detection based on RT-qPCR.

Carbon-Oxygen Radical Assisted Growth of Defect-Free Graphene Films Using Low-Temperature Chemical Vapor Deposition.

Low-temperature chemical vapor deposition growth of graphene films is a long-term pursuit in the graphene synthesis field because of the low energy consumption, short heating-cooling process and low wrinkle density of as-obtained films. However, insufficient energy supply at low temperature (below 850 °C) usually leads to the difficulty in carbon source dissociation, graphene growth, and defect healing. Herein, a Carbon-Oxygen (C─O) radical assisted strategy is proposed for low-temperature growth of defect-free, wrinkle-free, and single-crystalline graphene films by using methanol precursor.

Non-Canonical C Homoterpene Biosynthesis Widespread in Actinobacteria.

A novel biosynthetic pathway towards the rare and underexplored non-canonical family of homoterpenes was discovered in actinobacteria through targeted genome mining and enzymatic in vitro reconstitution. The pathway comprises initial methylation-induced double bond isomerization of farnesyl diphosphate (FPP) to (2E,7E)-6-methyl-farnesyl diphosphate, catalyzed by a novel family of methyltransferases with unique dual function. The resulting linear C double bond isomer of FPP constitutes the specific substrate for a distinct family of type I terpene cyclases, catalyzing diverse cyclization reactions.
