Although the significance of some plant WRKYs in response to cold stress have been identified, the molecular mechanisms of most WRKYs remain unclear in grapevine. In this study, we demonstrate that cold-induced expression of in executes a beneficial role in enhancing resistance by the regulating starch decomposition. VaWRKY65 was identified as an upstream transcriptional activator of through yeast one-hybrid library screening and validated to directly interact with the W-box region inside the promoter.

MicroRNAs (miRNAs) serve as key regulatory molecules mediating host-microbiota interactions. However, the specific fecal miRNAs regulating microbiota composition and metabolism in EA-treated constipated mice, along with their key targets, remain unidentified.

However, few studies have analyzed the relationship between specific dietary intakes and IBS using Mendelian randomization (MR). Exposure and outcome datasets were sourced from the IEU Open GWAS project.

Energy metabolism and the intestinal barrier perform distinct yet complementary roles that uphold intestinal ecological equilibrium. Disruptions in energy metabolism can compromise the integrity of the intestinal barrier; for example, inactivation of the AMPK pathway may lead to reduced expression of proteins associated with tight junctions.

Our previous study discovered that a portion of primary cultured mouse neonatal cortical astrocytes can be directly converted into neurons after exposure to a neurogenic induction condition. Recent in vivo studies have demonstrated astrocyte heterogeneity in terms of their developmental origin, molecular profile, physiology, and functional outputs.

In this study, we identified a grapevine cold-induced basic helix-loop-helix (bHLH) transcription factor (VvbHLH036). Overexpression and CRISPR/Cas9-mediated knockout (KO) of VvbHLH036 enhanced and decreased cold tolerance in grapevine roots, respectively.

Methods: Forty female SD rats were randomly divided into blank, model, electroacupuncture (EA), and agonist groups, with 10 rats in each group. Except for the blank group, rats in the other groups were given folium sennae infusion by gavage combined with chronic unpredictable mild stress to establish IBS-D model.
is a tetraploid species belonging to the Vitaceae family and is known for the Crassulacean acid metabolism (CAM) pathway in the succulent stem, while the leaves perform C photosynthesis. Here, we report a high-quality genome of comprising a total size of 679.2 Mb which was phased into two subgenomes.

In eukaryotes, the study of DNA epigenetic modifications has been confined to 5mC and its derivatives for decades. However, rapid developing approaches have witnessed the expansion of DNA modification reservoirs during the past several years, including the identification of 6mA, 5gmC, 4mC, and 4acC in diverse organisms.

The senescence of NSCs may be associated with the onset and progression of Alzheimer's disease (AD). Our study reveals a noteworthy finding, indicating that the AD-associated pathogenic protein amyloid-β (Aβ) substantially enhances senescence-related characteristics of human NSCs.

Methods: Publications related to acupuncture regulation on the ANS were retrieved from the Web of Science Core Collection (WoSCC) database. CiteSpace software was used to analyze the datasets and generate knowledge maps.
To reduce the influence of gain-phase errors and improve the performance of direction-of-arrival (DOA) estimation, a robust sparse Bayesian two-dimensional (2D) DOA estimation method with gain-phase errors is proposed for L-shaped sensor arrays. The proposed method introduces an auxiliary angle to transform the 2D DOA estimation problem into two 1D angle estimation problems. A sparse representation model with gain-phase errors is constructed using the diagonal element vector of the cross-correlation covariance matrix of two submatrices of the L-shaped sensor array.
