Article Synopsis
  • The study investigates the causal relationship between gut microbiota (GM) and cardiac structure and function using a two-sample Mendelian randomization approach, analyzing data from large genome-wide association studies.
  • Findings indicate 93 causal associations between the abundance of 44 GM genera and various parameters of cardiac health, with consistent results across different analytical methods and no detected pleiotropy.
  • The results suggest that GM may influence cardiac health through mechanisms related to myocardial cell development and cardiac contractility, indicating its potential role as a residual risk factor in cardiovascular health.

Article Synopsis
  • Pine wilt disease (PWD) poses a significant threat to pine trees and results in major economic losses, highlighting the need for better understanding of its molecular mechanisms for effective prevention and treatment.
  • Researchers identified a key virulence effector, BxNMP1, that is expressed early during the infection and interacts with important proteins in pine trees, suggesting it plays a role in disease severity.
  • The study indicates that BxNMP1 not only regulates the pathogenicity of the disease but also interferes with the host's natural defense mechanisms, providing insights that might help in developing strategies for combating PWD.

Bursaphelenchus xylophilus is the pathogen of pine wilt disease, which can devastate the pine forest ecosystem. Usually, plant cells generate reactive oxygen species (ROS) as a defensive substance or signalling molecules to resist the infection of nematodes. However, little is known about how B.

Lipase is involved in lipid hydrolysis, which is related to nematodes' energy reserves and stress resistance. However, the role of lipases in Bursaphelenchus xylophilus, a notorious plant-parasitic nematode responsible for severe damage to pine forest ecosystems, remains largely obscure. Here, we characterized a class III lipase as a candidate effector and named it BxLip-3.

Article Synopsis
  • - Pine wilt disease, caused by a specific pathogen, leads to significant economic losses in conifer production by hindering host immune responses through effector proteins.
  • - The study identifies two new effector proteins, BxKU1 and BxKU2, that employ different strategies to suppress plant immunity; they differ in structure, expression patterns, and their effects on host reproduction and feeding rates when silenced.
  • - Both effectors were found to interact with a specific protein (TLP4) in the host, revealing a complex immune evasion strategy that enhances our understanding of plant-pathogen interactions.

Article Synopsis
  • The pinewood nematode is one of the top ten plant-parasitic nematodes, causing pine wilt, which negatively impacts both the economy and sustainable development in East Asia.
  • Researchers cloned and studied a pathogenic protein called BxTTR-52 from the nematode, which plays a role in immune evasion by suppressing the host plant's immune response.
  • The study found that BxTTR-52 is mostly produced in the nematode's esophageal glands and affects the infection process, revealing potential targets for managing the disease in pine trees.

The migratory plant-parasitic nematode is the pathogen of the pine wilt disease (PWD), causing serious damage to pine forests in China. During the process of plant resistance to multiple pathogens, plant immunity plays a key role. In this current study, the pathogen-associated molecular pattern (PAMP) BxCDP1 in has been identified, but the host target protein of BxCDP1 and its key amino acid region inducing the plant immunity have yet to be elucidated.

is the most economically important species of migratory plant-parasitic nematodes (PPNs) and causes severe damage to forestry in China. The successful infection of relies on the secretion of a repertoire of effector proteins. The effectors, which suppress the host pine immune response, are key to the facilitation of parasitism.

Background: Bursaphelenchus xylophilus is the causal agent of pine wilt disease (PWD) that has caused enormous ecological and economic losses in China. The mechanism in the interaction between nematodes and pine remains unclear. Plant parasitic nematodes (PPNs) secrete effectors into host plant tissues.

Background: Left ventricular (LV) remodeling after ST-segment elevation myocardial infarction (STEMI) is a major pathological basis associated with heart failure and increased mortality. Exercise-based cardiac rehabilitation has been verified to significantly improve prognosis and quality of life. As a traditional Chinese Qigong, Baduanjin exercise has effectively alleviated adverse LV remodeling in STEMI patients.

Background: The pine wilt disease (PWD) caused by Bursaphelenchus xylophilus is a devastating forest disease and its pathogenesis remains unclear. Secreted enzymes and proteins are important pathogenicity determinants and Bx-FAR-1 is an important pathogenic protein involved in the interaction between pine and B. xylophilus.

Emerging evidence revealed the critical roles of long non-coding RNAs (lncRNAs) in maintaining genomic instability. However, genome instability-associated lncRNAs (GILncRNAs) and their performance in clinical prognostic significance in hepatocellular carcinoma (HCC) are rarely reported. Our study constructed a computational framework integrating somatic mutation information and lncRNA expression profiles of HCC genome and we identified 88 GILncRNAs of HCC.

The plant-parasitic nematode Bursaphelenchus xylophilus, the causal agent of pine wilt disease (PWD), causes enormous economic loss every year. Currently, little is known about the pathogenic mechanisms of PWD. Several effectors have been identified in B.

We aimed to explore the crucial miRNA-mRNA axis through bioinformatics analysis and provide evidences for the development of pathophysiological mechanisms and new therapies for HBV-related HCC. MiRNA (GSE76903) and mRNA (GSE77509) dataset were used to screen differentially expressed miRNAs (DE-miRNAs) and differentially expressed mRNAs (DE-mRNAs) using R software. Overlapping genes between DE-mRNAs and target genes of DE-miRNAs were identified as candidate genes.

DRB sensitivity-inducing factor (DSIF or Spt4/5) is a conserved transcription elongation factor that both inhibits and stimulates transcription elongation in metazoans. In and vertebrates, DSIF together with negative elongation factor (NELF) associates with RNA polymerase II during early elongation and causes RNA polymerase II to pause in the promoter-proximal region of genes. The mechanism of how DSIF establishes pausing is not known.

Background: in many differentiated cells, microtubules are organized into polarized noncentrosomal arrays, yet few mechanisms that control these arrays have been identified. For example, mechanisms that maintain microtubule polarity in the face of constant remodeling by dynamic instability are not known. Drosophila neurons contain uniform-polarity minus-end-out microtubules in dendrites, which are often highly branched.

Tumor angiogenesis, induced by tumor-secreted pro-angiogenic factors, is an essential process for cancer development and metastasis. CD146 is identified as an endothelial cell adhesion molecule and implicated in blood vessel formation, however, its exact role in angiogenesis, particularly tumor angiogenesis, and its potential function of mediating downstream signaling are still unclear. In present study, we evidenced that silencing endogenous endothelial CD146 by RNAi significantly impaired hepatocarcinoma cell secretions-promoted tubular morphogenesis and -enhanced motility of endothelial cells.

Two coloured bacteria were isolated from the same plate for detecting cultivable bacteria from the air of Xinjiang in China. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the isolates were members of the genus Kocuria, in which they represented two novel lineages. Although the two strains presented high 16S rRNA gene sequence similarity (above 97 %), their DNA G+C contents were very different (6 mol%).
