Sandalwood (), a culturally significant and economically valuable horticultural species, is renowned for its heartwood and essential oils enriched with sesquiterpene compounds such as santalol. Despite progress in elucidating the biosynthetic pathway of these valuable metabolites, the transcriptional regulation of this process, particularly under abiotic stress conditions, remains largely unexplored. Under drought conditions, we observed a marked increase in expression, paralleled by elevated levels of santalols.

Type III interferons (IFNs) primarily act on epithelial cells and protect against virus infection of the mucosa, whereas type I IFNs act more systemically. To date, it has been unknown which epithelial subtypes in the upper airways, the primary site for initial infection for most respiratory viruses, primarily rely on type III IFN or type I IFNs for antiviral protection. To address this question, we performed a single-cell transcriptomics analysis of the epithelial IFN-mediated response focusing on the upper airways of mice.

Sorbitol, a main photosynthate and transport carbohydrate in all tree fruit species in Rosaceae, acts as a signal controlling resistance against Alternaria (A.) alternata in apple by altering the expression of the MdNLR16 resistance gene via the MdWRKY79 transcription factor. However, it is not known if N-methyladenosine (mA) methylation of the mRNAs of these genes participates in the process.

Thyroid cancer (THCA) is an increasingly common malignant tumor of the endocrine system, with its incidence rising steadily in recent years. For patients who experience recurrence or metastasis, treatment options are relatively limited, and the prognosis is poor. Therefore, exploring new therapeutic strategies has become particularly urgent.

Salt enhances flavor and salinity in Chinese curing; however, excessive use can pose health risks, while reducing NaCl may harm taste. This study utilized targeted and untargeted metabolomics to investigate the intrinsic molecular mechanisms that drive flavor formation in cured sea bass subjected to salt. Glycine, succinic acid, lactic acid and uridine significantly contributed to the taste profile of the cured sea bass.

High carbohydrate availability promotes malic acid accumulation in fleshy fruits, but the underlying mechanism is not known. Here, we show that antisense repression of ALDOSE-6-PHOSPHATE REDUCTASE in apple (Malus domestica) decreases the concentrations of sorbitol and malate and the transcript levels of several genes involved in vacuolar malate transport, including the aluminum-activated malate transporter (ALMT) gene MdALMT9 (Ma1), the P-ATPase gene MdPH5, the MYB transcription factor gene MdMYB73, and the cold-induced basic helix-loop-helix transcription factor gene MdCIbHLH1, in fruit and leaves. We identified a linker histone H1 variant, MdH1.

Background: Low-grade endometrial stromal sarcoma (LG-ESS) is a rare uterine malignancy characterized by its complex tumor microenvironment (TME) and high recurrence rates, posing challenges to accurate prognosis and effective treatment. Identifying prognostic biomarkers is essential for improving patient stratification and guiding therapeutic strategies.

Methods: Using single-cell transcriptome analysis combined with H&E and multiplex immunofluorescence staining, we identified a subpopulation of tumor cells in LG-ESS and further validated the association of this subpopulation and its characteristic genes with LG-ESS prognosis by molecular characterization and bulk transcriptome data.

Objective: In this study, clinical bioinformatics analysis was used to identify potential biomarkers of acute myeloid leukemia (AML) occurrence and development, drug resistance, and poor prognosis to provide a theoretical basis for the treatment of AML.

Methods: On the basis of the TCGA, GEO, and GTEx databases, an AML secondary database was established, and differential expression analysis and WGCNA were carried out to identify genes related to the prognosis of AML patients. Survival analysis was carried out for internal verification of key genes, and GEO data were used for external verification to obtain core genes related to prognosis.

Pelvic organ prolapse is a condition that significantly affects women's quality of life. The pathological mechanism of pelvic organ prolapse is not yet fully understood, and its pathogenesis is often caused by multiple factors, including the metabolic imbalance of the extracellular matrix. This study aims to investigate the role of miR-5195-3p, a microRNA, in the pathology of pelvic organ prolapse and its regulatory mechanism.

Article Synopsis
  • The study aimed to identify clinical factors affecting survival and treatment outcomes for patients with angioimmunoblastic T-cell lymphoma (AITL) and to create a new prognostic model for this disease.
  • An analysis of 231 AITL patients showed a median age of 63, with most in advanced stages, and the overall survival (OS) and progression-free survival (PFS) were 17 months and 6 months, respectively.
  • The newly developed prognostic model categorizes patients into risk groups based on factors such as age and performance status, allowing for better prediction of survival outcomes, though there's still no clear consensus on the best initial treatment for AITL.

Superhydrophobic materials have been widely applied in oil-water separation, self-cleaning, antifouling, and drag reduction; however, their role in liquid evaporation and drying remains unexplored. Inspired by the microstructure of the nonwetting legs of water striders, we designed a low-adhesion superhydrophobic cylindrical barrel (CB) derived from stainless-steel mesh (SSM) to enhance liquid thermal evaporation and drying. The CB was created by hydrothermally depositing zinc oxide (ZnO) with multilevel morphologies onto metal wires, followed by modification with low-surface-energy stearic acid (SA).

While the activities of certain proteases promote proteostasis and prevent neurodegeneration-associated phenotypes, the protease cathepsin B (CTSB) enhances proteotoxicity in Alzheimer's disease (AD) model mice, and its levels are elevated in brains of AD patients. How CTSB exacerbates the toxicity of the AD-causing Amyloid β (Aβ) peptide is controversial. Using an activity-based probe, aging-altering interventions and the nematode C.

The olive tree is an important oil woody plant with high economic value, yet it is vulnerable to the attack of numerous fungi. The successful control of olive fungal diseases requires a comprehensive understanding of the disease resistance mechanisms in plants. Here, we isolated Alternaria alternata from the diseased leaves of olive plants, and screened a resistant ("Leccino") and susceptible ("Manzanilla de Sevilla") cultivar from eight olive cultivars to explore their resistance mechanisms.

Starting from a generic model based on the thermodynamics of mixing and abstracted from the chemistry and microscopic details of solution components, three consistent and complementary computational approaches are deployed to investigate the general condition for polymer cononsolvency in binary mixed solvents at the order. The study reveals χ - χ + χ as the underlying universal parameter that regulates cononsolvency, where χ is the immiscibility parameter between the α- and β-component. Two disparate cononsolvency regimes are identified for χ - χ + χ < 0 and χ - χ + χ > 2, respectively, based on the behavior of the second osmotic virial coefficient at varying solvent mixture composition .
