Construction of an Ag-functionalized structural color hydrogel sensor for colorimetric detection of glutathione.

An Ag-functionalized structural color hydrogel (Ag-SCH) sensor is constructed for colorimetric detection of glutathione (GSH). The hydrogel is prepared by using the coordination of Ag and 1-vinylimidazole (1-VI) as cross-linking network. GSH acts as a competitive ligand to break the coordination between Ag and 1-VI, leading to the expansion and structural color change of the hydrogel.

Patient-reported outcomes after lobectomy vs. segmentectomy for early-stage non-small cell lung cancer.

Background: Surgical resection is the cornerstone for early-stage non-small cell lung cancer (NSCLC), with lobectomy historically standard. Evolving techniques have spurred debate comparing lobectomy and segmentectomy. This study analyzed early postoperative patient-reported symptoms and functional status in patients with early NSCLC undergoing either procedure.

Fine mapping of the dominant female sterility gene and novel model of hybrid seed production in cabbage (Brassica oleracea L. var. capitata).

Hybrid breeding based on male sterility requires the removal of male parents, which is time- and labor-intensive; however, the use of female sterile male parent can solve this problem. In the offspring of distant hybridization between Brassica oleracea and Brassica napus, we obtained a mutant, 5GH12-279, which not only fails to generate gynoecium (thereby causing female sterility) but also has serrated leaves that could be used as a phenotypic marker in seedling screening. Genetic analysis revealed that this trait was controlled by a single dominant gene.

The X-Age Project to construct a Chinese aging clock.

The global surge in the population of people 60 years and older, including that in China, challenges healthcare systems with rising age-related diseases. To address this demographic change, the Aging Biomarker Consortium (ABC) has launched the X-Age Project to develop a comprehensive aging evaluation system tailored to the Chinese population. Our goal is to identify robust biomarkers and construct composite aging clocks that capture biological age, defined as an individual's physiological and molecular state, across diverse Chinese cohorts.

Emerging strategies, applications and challenges of targeting NAD in the clinic.

Beyond their classical functions as redox cofactors, recent fundamental and clinical research has expanded our understanding of the diverse roles of nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP) in signaling pathways, epigenetic regulation and energy homeostasis. Moreover, NAD and NADP influence numerous diseases as well as the processes of aging, and are emerging as targets for clinical intervention. Here, we summarize safety, bioavailability and efficacy data from NAD-related clinical trials, focusing on aging and neurodegenerative diseases.

Nuclear glycine decarboxylase suppresses STAT1-dependent MHC-I and promotes cancer immune evasion.

Inadequate antigen presentation by MHC-I in tumor microenvironment (TME) is a common immune escape mechanism. Here, we show that glycine decarboxylase (GLDC), a key enzyme in glycine metabolism, functions as an inhibitor of MHC-I expression in EGFR-activated tumor cells to induce immune escape by a mechanism independent of its enzymatic activity. Upon EGFR activation, GLDC is phosphorylated by SRC and subsequently translocated to the nucleus in human NSCLC cells.

Semaphorin 3A-mediated perineuronal nets formation incubates depressive-like behaviors in male mice via activating parvalbumin-expressing interneurons.

Dysfunction of parvalbumin-expressing interneurons (PV-INs) in the cerebral cortex has been implicated in major depressive disorder. Perineuronal nets (PNNs), which encapsulate PV-INs, are considered to influence the structural and functional properties of PV-INs. Semaphorin 3A (Sema3A) is a secreted protein constituent of PNNs, but the specific roles of Sema3A in modulating PV-INs during stress remain unknown.

SLC7A11-AS1 contributes to prolonged activation of activin A/Smad signaling by suppressing PPM1A myristoylation in pancreatic cancer.

Background: Activin A/Smad signaling plays an important role in promoting cancer stemness and chemoresistance in pancreatic ductal adenocarcinoma (PDAC), however the precise regulation on the termination of this pathway has not been fully understood.

Methods: LncRNA SLC7A11-AS1 interacting proteins were identified through RNA pull-down followed by LC-MS/MS. The protein interaction was analyzed by co-immunoprecipitation.

Liver steatosis mediates the association between metabolic score for insulin resistance and obstructive sleep apnea.

Obstructive sleep apnea (OSA) is associated with metabolic disorders such as insulin resistance and liver fat accumulation. However, the specific mediating role of liver-related metabolic indicators in this association has not been fully studied. The purpose of this study was to investigate the relationship between Metabolic Score for Insulin Resistance (METS-IR) and OSA, focusing on the mediating effects of liver fat percentage (PLF) and hepatic steatosis index (HSI).

CETN3 deficiency induces microcephaly by disrupting neural stem/progenitor cell fate through impaired centrosome assembly and RNA splicing.

Primary microcephaly, a rare congenital condition characterized by reduced brain size, occurs due to impaired neurogenesis during brain development. Through whole-exome sequencing, we identified compound heterozygous loss-of-function mutations in CENTRIN 3 (CETN3) in a 5-year-old patient with primary microcephaly. As CETN3 has not been previously linked to microcephaly, we investigated its potential function in neurodevelopment in human pluripotent stem cell-derived cerebral organoids.

Manipulating Zika virus RNA tertiary structure for developing tissue-specific attenuated vaccines.

Traditional live attenuated vaccines (LAVs) are typically developed through serial passaging or genetic engineering to introduce specific mutations or deletions. While viral RNA secondary or tertiary structures have been well-documented for their multiple functions, including binding with specific host proteins, their potential for LAV design remains largely unexplored. Herein, using Zika virus (ZIKV) as a model, we demonstrate that targeted disruption of the primary sequence or tertiary structure of a specific viral RNA element responsible for Musashi-1 (MSI1) binding leads to a tissue-specific attenuation phenotype in multiple animal models.

It is characterized by subcutaneous nodules, eosinophilia, and elevated IgE levels. Its unclear etiology and similarities to malignancies create diagnostic and therapeutic challenges.

Removal of cadmium from aqueous solution using montmorillonite-supported nanoscale zero-valent iron.

Cadmium (Cd) contamination in water poses a critical global challenge. A novel nanocomposite, montmorillonite (Mt)-supported nanoscale zero-valent iron (Mt-nZVI), synthesized by liquid phase reduction, offers a promising method for effectively removing Cd. The material underwent characterization through various techniques, including X-ray diffraction (XRD) and Scanning Electron Microscope(SEM).

Cell death in multiple sclerosis.

Multiple sclerosis (MS) is a chronic autoimmune disorder of the central nervous system (CNS) characterized by inflammatory demyelination and progressive neurodegeneration. Although current disease-modifying therapies modulate peripheral autoimmune responses, they are insufficient to fully prevent tissue specific neuroinflammation and long-term neuronal and oligodendrocyte loss. Growing evidence implicates various regulated cell death (RCD) pathways, including apoptosis, necroptosis, pyroptosis, and ferroptosis, not only as downstream consequences of chronic inflammation, but also as active drivers of demyelination, axonal injury, and glial dysfunction in MS.

Long non-coding RNA STMN1P2 promotes breast cancer doxorubicin resistance by inhibiting pyroptosis through the hnRNPU-EZH2-TARF6-MALT1-caspase-1 pathway.

Chemotherapeutic resistance is a significant issue in the treatment of breast cancer, which is related to pyroptosis inhibition. Increasing evidence suggests that long non-coding RNAs (lncRNAs) contribute to tumorigenesis and drug resistance. In this study we investigated the role of the lncRNA STMN1P2 in doxorubicin resistance in breast cancer, as well as its correlation with pyroptosis inhibition.

Purifying recombinant proteins from Nicotiana benthamiana for structural studies.

Structural biology is fundamental to understanding the molecular basis of biological processes. While machine learning-based protein structure prediction has advanced considerably, experimentally determined structures remain indispensable for guiding structure-function analyses and for improving predictive modeling. However, experimental studies of protein complexes continue to pose challenges, particularly due to the necessity of high protein concentrations and purity for downstream analyses such as cryogenic electron microscopy.

Intestinal taurine acts as a novel immunometabolic modulator of IBD by degrading redundant mitochondrial RNA.

Anti-tumor necrosis factor (TNF) therapy for inflammatory bowel disease (IBD) is hampered by issues of nonresponse and resistance, highlighting the urgent need for alternative or complementary treatments. Our study revealed significant upregulation of taurine in the intestinal tissues of IBD patients, which was inversely related to the severity of the disease. A key discovery was that TNF directly induced taurine synthesis in intestinal epithelial cells and increased the production of angiogenin, a nuclease that degrades mitochondrial RNA, which is known to amplify inflammatory responses.
