Alzheimer's disease (AD), the most prevalent form of dementia in the elderly, involves critical changes such as reduced aerobic glycolysis in astrocytes and increased neuronal apoptosis, both of which are significant in the disease's pathology. In our study, astrocytes treated with amyloid β1-42 (Aβ) to simulate AD conditions exhibited upregulated expressions of small ubiquitin-like modifier (SUMO)-specific protease 1 (SENP1) and Pumilio RNA Binding Family Member 2 (PUM2), alongside decreased levels of Nuclear factor erythroid 2-related factor 2 (NRF2). SENP1 is notably the most upregulated SUMOylation enzyme in Aβ-exposed astrocytes.

Department of Cardiology, Cardiac Arrhythmia Center, Affiliated Hospital of Nantong University, Nantong 226001, China. Electronic address:

Doxorubicin (DOX), a chemotherapeutic agent utilized in the management of cancer, provokes cardiotoxicity although effective remedy is lacking. Given that DOX provokes oxidative stress and cell death in cardiomyocytes, this study evaluated the possible involvement of cuproptosis, a newly identified form of cell death, in DOX-instigated cardiac remodeling and contractile dysfunction, alongside the impact of the heavy metal scavenger metallothionein (MT) on DOX cardiomyopathy. Cardiac-specific MT transgenic and wild-type (WT) mice were treated with DOX (5 mg/kg/wk.

A Susceptible Cell-Selective Delivery (SCSD) of mRNA-Encoded Cas13d Against Influenza Infection.

Adv Sci (Weinh)

January 2025

National Key Laboratory of Veterinary Public Health and Safety, College of Veterinary Medicine, China Agricultural University, Beijing, 100193, China.

To bolster the capacity for managing potential infectious diseases in the future, it is critical to develop specific antiviral drugs that can be rapidly designed and delivered precisely. Herein, a CRISPR/Cas13d system for broad-spectrum targeting of influenza A virus (IAV) from human, avian, and swine sources is designed, incorporating Cas13d mRNA and a tandem CRISPR RNA (crRNA) specific for the highly conserved regions of viral polymerase acidic (PA), nucleoprotein (NP), and matrix (M) gene segments, respectively. Given that the virus targets cells with specific receptors but is not limited to a single organ, a Susceptible Cell Selective Delivery (SCSD) system is developed by modifying a lipid nanoparticle with a peptide mimicking the function of the hemagglutinin of influenza virus to target sialic acid receptors.

State Key Laboratory of Rice Biology, Ministry of Agricultural and Rural Affairs Key Laboratory of Molecular Biology of Crop Pathogens and Insect Pests, Institute of Insect Sciences, Zhejiang University, Hangzhou, 310058, China.

The effects of drought stress on stomatal opening dynamics, plant volatile organic compound (VOC) emissions and plant-insect interactions have been well-documented individually, but how they interact mechanistically remains poorly studied. Here, we studied how drought-triggered stomatal closure affects VOC emission and plant-trophic interactions by combining RNAi silencing, molecular biological and chemical analyses (GC-MS) of a potato-tuber moth-egg parasitoid tritrophic system. Drought stress attenuated stomatal apertures and VOC emissions, which made the potato (Solanum tuberosum L.

DUO1 Activated Zinc Finger (AtDAZ) protein role in the generative cell body morphogenesis.

Plant Mol Biol

January 2025

National Key Laboratory for Tropical Crop Breeding, Tropical Crop Genetic Resources Institute, Chinese Academy of Tropical Agricultural Sciences, Sanya, Haikou, 572024/571101, Hainan, China.

Arabidopsis MYB transcription factor, AtDUO1 regulates generative cell body (GC) morphogenesis from round to semi and fully elongated forms before pollen mitosis-II (PM II). It was hypothesised that DUO1 might regulate morphogenesis through any of its direct target genes or components of the DUO1-DAZ1 network. The developmental analysis of plants harbouring T-DNA insertions in some DUO1 target genes using light and fluorescence microscopy revealed abnormal GC morphogenesis only in daz1 and daz2, but gcs1, trm16, mapkkk10, mapkkk20, tet11, and tip1 all undergo normal elongation indicating that these target genes have no important roles in morphogenesis or may be redundant.

Noise-induced hearing loss (NIHL) is primarily driven by inflammatory processes within the cochlea, where noise exposure triggers the activation of the NOD-like receptor protein 3 (NLRP3) inflammasome, leading to an inflammatory cascade. The interaction between increased NLRP3 expression and NF-κB activity can further amplify cochlear inflammation. Our findings reveal that (R)-PFI-2 hydrochloride, a selective inhibitor of the SETD7 enzyme, effectively inhibits the activation of the cochlear NF-κB pathway, suppresses the release of pro-inflammatory factors, and prevents inflammasome assembly.

Litter size traits of sows are crucial for the economic benefits of the pig industry. Three phenotypic traits of 1,206 Large White (LW) pigs, that is, the total number born (TNB), number born alive (NBA), and number of healthy piglets (NHP), were recorded. We evaluated a series of genomic best linear unbiased prediction (GBLUP) models that sequentially added additive effects (model A), dominance effects (model A+D), and epistatic effects (model A+D+AA, model A+D+AA+AD, and model A+D+AA+AD+DD) using chip data and imputed whole-genome sequencing (WGS) data to estimate genetic parameters and predictive accuracy.

Soybean, the fourth most important crop in the world, uniquely serves as a source of both plant oil and plant protein for the world's food and animal feed. Although soybean production has increased approximately 13-fold over the past 60 years, the continually growing global population necessitates further increases in soybean production. In the past, especially in the last decade, significant progress has been made in both functional genomics and molecular breeding.
