Combined genomic, transcriptomic, and metabolomic analyses provide insights into the fruit development of bottle gourd ().

Bottle gourd ( (Molina) Standl) is a widely distributed Cucurbitaceae species, but gaps and low-quality assemblies have limited its genomic study. To address this, we assembled a nearly complete, high-quality genome of the bottle gourd (Pugua) using PacBio HiFi sequencing and Hi-C correction. The genome, being 298.

Expression complementation between fundamental biological pathways in Populus hybrid contributes to heterosis in cadmium (Cd) accumulation and tolerance.

To reveal the pattern of heterosis in cadmium (Cd) bio-accumulation of poplar and whether the heterosis can promote the phytoremediation efficiency of Cd-polluted soil, the poplar hybrid variety QB-5 (I-101 × 84K) and its female parent I-101 (Populus alba) and male parent 84K (P. alba × P. glandulosa) were employed in a hydroponic experiment and a field trial.

Cross-sectional study on the association between serum uric acid levels and non-alcoholic fatty liver disease in an elderly population.

Non-alcoholic fatty liver disease (NAFLD) is a prevalent liver disorder strongly associated with metabolic dysfunction, particularly in elderly populations where it presents with higher prevalence and severity. This study aimed to investigate the association between serum uric acid (SUA) levels and NAFLD in older adults, focusing on the independent effect of hyperuricemia on NAFLD risk. We enrolled 469 individuals aged ≥ 65 years who underwent community health checkups.

Detection of inversion with breakpoints in causing MPS VI by whole-genome sequencing: lessons learned and best practices.

Introduction: Mucopolysaccharidosis type VI (MPSVI), an autosomal recessive lysosomal storage disorder caused by pathogenic variants in gene. Usually, whole exome sequencing (WES) can identify these variants, and if WES failed to detect causative variants, whole-genome sequencing (WGS) may be considered to investigate deep intronic variations and structural alterations in patients.

Methods: Whole-exome sequencing (WES) and whole genome sequencing (WGS) were performed in a Chinese family having a boy with suspected diagnosis of MPS with macrocephaly, coarse facial features, broad forehead, thick lips, frontal bossing, craniosynostosis, blue spots, frequent upper respiratory infections, inguinal hernia, and dysostosis multiplex.

Reference intervals of inhibin B in Chinese children on chemiluminescence analyzer.

Inhibin B (INHB) is an emerging biomarker of sexual function diseases, but its clinical use in children is hindered due to the lacking reference intervals (RIs) based on age and sex. A total of 622 healthy Chinese children including 48.6% females and 51.

Discovery of potent hypoxia-inducible factor-1α (HIF-1α) degraders by proteolysis targeting chimera (PROTAC).

Under hypoxic conditions in tumor cells, HIF-1α is unable to bind to VHL E3 ligase due to the blocked hydroxylation reaction, resulting in impaired degradation and intracellular accumulation. Mounting evidences show a close association between HIF-1α overexpression and drug resistance, treatment failure, and increased mortality. To address HIF-1α overexpression, we innovatively introduced an E3 ligase ligand to the HIF-1α inhibitor IDF-11774 using the PROTACs strategy, aiming to reactivate the degradative pathway impeded under hypoxia, and thereby achieve the degradation of HIF-1α protein under hypoxia.

Analysis of epilepsy-associated variants in HCN3 - Functional implications and clinical observations.

Objective: This case study investigates the role of hyperpolarization-activated, cyclic nucleotide-gated (HCN) ion channels, which are integral membrane proteins crucial for regulating neuronal excitability. HCN channels are composed of four subunits (HCN1-4), with HCN1, HCN2, and HCN4 previously linked to epilepsy. However, the role of the HCN3 in epileptogenesis remains underexplored.

Diversity and Composition of Fungicolous Fungi Residing in Macrofungi from the Qinling Mountains.

Sporocarps of macrofungi support other diverse fungal species that are termed fungicolous fungi. However, the external environmental factors that affect the diversity and composition of fungicolous fungal communities remains largely unknown. In this study, the diversities, composition, and trophic modes of fungicolous fungal communities residing in host macrofungi from diverse habitats in the Qinling Mountains were analyzed.

DOR activation in mature oligodendrocytes regulates α-ketoglutarate metabolism leading to enhanced remyelination in aged mice.

The decreased ability of mature oligodendrocytes to produce myelin negatively affects remyelination in demyelinating diseases and aging, but the underlying mechanisms are incompletely understood. In the present study, we identify a mature oligodendrocyte-enriched transcriptional coregulator diabetes- and obesity-related gene (DOR)/tumor protein p53-inducible nuclear protein 2 (TP53INP2), downregulated in demyelinated lesions of donors with multiple sclerosis and in aged oligodendrocyte-lineage cells. Dor ablation in mice of both sexes results in defective myelinogenesis and remyelination.

Identification of two novel variants in ALG11 causing congenital disorder of glycosylation.

Background: Congenital disorders of glycosylation (CDG) represent a heterogeneous group of rare inherited metabolic disorders due to abnormalities in protein or lipid glycosylation pathways, affecting multiple systems, and frequently being accompanied by neurological symptoms. ALG11-CDG, also known as CDG-1p, arises from a deficiency in a specific mannosyltransferase encoded by the ALG11 gene. To date, only 17 cases have been documented, and these patients have prominent clinical phenotypes, including seizures, developmental delay, and microcephaly.

Phytoremediation efficiency of poplar hybrid varieties with diverse genetic backgrounds in soil contaminated by multiple toxic metals (Cd, Hg, Pb, and As).

Fifteen poplar varieties were used in a field trial to investigate the phytoremediation efficiency, stress resistance, and wood property of poplar hybrid varieties with diverse genetic backgrounds under the composite pollution of heavy metals. The coefficient of variation and clone repeatability for growth traits and Cd concentration were large. The Cd accumulation of poplar varieties 107 and QHQ reached 1.

Blocking TGFβR synergistically enhances anti-tumor effects of anti-PD-1 antibody in a mouse model of incomplete thermal ablation.

The mechanism of early tumor recurrence after incomplete microwave ablation (iMWA) is poorly understood. The anti-programmed cell death protein 1 (anti-PD-1) monotherapy is reported to be ineffective to prevent the progression of residual tumor resulted from iMWA. Transforming growth factor-β (TGFβ) signaling pathway plays an important role in tumorigenesis and development.

Dynamics and Internal Structure Evolution during the Glass Transition of the Ethylene-Cyclic Olefin Copolymers: A Molecular Dynamics Simulation.

Amorphous ethylene-cyclic olefin copolymers (COCs) which can be used in cell phone lenses and prefilled syringes have attracted increasing attention due to their excellent and tunable thermal properties. In order to better explain the influence of COC microstructure (cyclic olefin types and content) on the glass transition mechanism, we used molecular dynamics (MD) simulations to track the evolution of free volume, diffusion coefficients, atomic mobility, trans conformation probabilities, and characteristic parameters of α-relaxation kinetics during the quenching process. MD results show that for the classic COC E--NB (ethylene-norbornene copolymer), an increase in cyclic olefin content from 25 to 50 mol % reduces atomic mobility, limiting the molecular chain movement at higher temperatures and improving .

High‑oxygen-modified atmospheric packaging delays flavor and quality deterioration in fresh-cut broccoli.

The purpose of this study was to investigate the impact of high‑oxygen-modified atmospheric packaging (HOMAP) on aroma changes in fresh-cut broccoli during storage and to explore its regulatory mechanisms. The results showed that HOMAP reduced the levels of undesirable aroma substances hexanoic acid, isobutyric acid, cyclopentanone and increased glucosinolate accumulation by inhibiting the expression of arogenate/prephenate dehydratase (ADT), bifunctional aspartate aminotransferase and glutamate/aspartate-prephenate aminotransferase (PAT), thiosulfate/3-mercaptopyruvate Transferase (TST) to reduce the odor of fresh-cut broccoli. HOMAP inhibited the expression of respiratory metabolism related genes 6-phosphate fructokinase 1 (PFK), pyruvate kinase (PK), and NADH-ubiquinone oxidoreductase chain 6 (ND6).

Small-molecule-induced epigenetic rejuvenation promotes SREBP condensation and overcomes barriers to CNS myelin regeneration.

Remyelination failure in diseases like multiple sclerosis (MS) was thought to involve suppressed maturation of oligodendrocyte precursors; however, oligodendrocytes are present in MS lesions yet lack myelin production. We found that oligodendrocytes in the lesions are epigenetically silenced. Developing a transgenic reporter labeling differentiated oligodendrocytes for phenotypic screening, we identified a small-molecule epigenetic-silencing-inhibitor (ESI1) that enhances myelin production and ensheathment.

Effects of nitrate- and ammonium- nitrogen on anatomical and physiological responses of Catalpa bungei under full and partial root-zone drought.

Catalpa bungei is a precious timber species distributed in North China where drought often occurs. To clarify adaptive responses of C. bungei to partial- and full- root-zone drought under the influence of nitrogen forms, a two-factor experiment was conducted in which well-watered (WW), partial root-zone drought in horizontal direction (H-PRD) and in vertical direction (V-PRD), and full root-zone drought (FRD) were combined with nitrate-nitrogen (NN) and ammonium-nitrogen (AN) treatments.

Activated phosphoinositide 3-kinase δ syndrome caused by PIK3CD mutations: expanding the phenotype.

Background: Germline heterozygous gain-of-function (GOF) mutations in the PIK3CD gene lead to a rare primary immunodeficiency disease known as activated phosphoinositide 3-kinase (PI3K) δ syndrome type 1(APDS1). Affected patients present a spectrum of clinical manifestations, particularly recurrent respiratory infections and lymphoproliferation, increased levels of serum immunoglobulin (Ig) M, Epstein-Barr virus (EBV) and cytomegalovirus (CMV) viremia. Due to highly heterogeneous phenotypes of APDS1, it is very likely that suspected cases may be misdiagnosed.

Revealing the Effect of the Molecular Weight Distribution on the Chain Diffusion and Crystallization Process under a Branched Trimodal Polyethylene System.

With the increasing demand for high-end materials, trimodal polyethylene (PE) has become a research hotspot in recent years due to its superior performance compared with bimodal PE. By means of molecular dynamics (MD) simulations, we aim to expound the effect of the molecular weight distribution (MWD) on the mechanism of nucleation and crystallization of trimodal PE. The crystallization rate is faster when short-chain branching is distributed on a single backbone compared to that on two backbones.
