Topological-Similarity Based Canonical Representations for Biological Link Prediction.

Graph machine learning algorithms are being commonly applied to a broad range of prediction tasks in systems biology. An important design criterion in this regard is the definition of "topological similarity" between two nodes in a network, which is used to design convolution matrices for graph convolution or loss functions to evaluate node embeddings. Many measures of topological similarity exist in network science literature (e.

This research also aimed to analyze the sources of these elements. Its findings revealed that the mean contents of Cr, Ni, Cu, Zn, Pb, As, Cd, and Hg were 54.

Effects of resistance exercise intensity on cerebral blood flow and cerebrovascular reactivity in healthy young males: A pilot study.

Exercise intensity has been shown to elicit different cerebral blood flow velocity (CBFv) responses. This study aimed to compare the acute effects of resistance exercise at different intensities on hemodynamics and cerebrovascular reactivity in healthy young males. Eleven healthy young males were recruited, and three trials of dumbbell alternating curls were performed in order of increasing intensity: low (30%-35% 1RM), medium (55%-60% 1RM), and high (75%-80% 1RM).

AURKB inhibition induces rhabdomyosarcoma apoptosis and ferroptosis through NPM1/SP1/ACSL5 axis.

Rhabdomyosarcoma (RMS) is one of the most common solid tumors in children and adolescents. Patients with relapsed/refractory RMS have limited treatment options, highlighting the urgency for the identification of novel therapeutic targets for RMS. In the present study, aurora kinase B (AURKB) was found to be highly expressed in RMS and associated with unfavorable prognosis of patients.

ROS-induced cytosolic release of mitochondrial PGAM5 promotes colorectal cancer progression by interacting with MST3.

Aberrant release of mitochondrial reactive oxygen species (mtROS) in response to cellular stress is well known for promoting cancer progression. However, precise molecular mechanism by which mtROS contribute to epithelial cancer progression remains only partially understood. Here, using colorectal cancer (CRC) models, we show that upon sensing excessive mtROS, phosphatase PGAM5, which normally localizes to the mitochondria, undergoes aberrant cleavage by presenilin-associated rhomboid-like protein (PARL), becoming released into the cytoplasm.

Integrative proteo-transcriptomic characterization of advanced fibrosis in chronic liver disease across etiologies.

Chronic hepatic injury and inflammation from various causes can lead to fibrosis and cirrhosis, potentially predisposing to hepatocellular carcinoma. The molecular mechanisms underlying fibrosis and its progression remain incompletely understood. Using a proteo-transcriptomics approach, we analyze liver and plasma samples from 330 individuals, including 40 healthy individuals and 290 patients with histologically characterized fibrosis due to chronic viral infection, alcohol consumption, or metabolic dysfunction-associated steatotic liver disease.

A testis-specific long non-coding RNA, 1700052I22Rik, regulates spermatid chromatin condensation in mice.

Long non-coding RNAs (lncRNAs), serving as diverse functional regulators, are abundantly expressed in the testis. However, many testis-specific or preferentially expressed lncRNAs remain uncharacterized. Here, we report a testis-specific lncRNA, 1700052I22Rik, which exhibits a dynamic expression pattern during spermatogenesis.

mA Reader PRRC2A Promotes Colorectal Cancer Progression via CK1ε-Mediated Activation of WNT and YAP Signaling Pathways.

Colorectal cancer (CRC) is the third most common cancer type and the second highest mortality rate among cancers. However, the mechanisms underlying CRC progression remain to be fully understood. In this work, a recently identified mA-modified RNA reader protein Proline-rich Coiled-coil 2a (PRRC2A) is markedly upregulated in CRC, and intestinal epithelium-specific deletion of Prrc2a significantly suppressed tumor cell growth, stemness, and migratory capacity, while its overexpression promoted these behaviors.

Probiotics and their metabolite spermidine enhance IFN-γCD4 T cell immunity to inhibit hepatitis B virus.

The therapeutic potential of commensal microbes and their metabolites is promising in the functional cure of chronic hepatitis B virus (HBV) infection, which is defined as hepatitis B surface antigen (HBsAg) loss. Here, using both specific-pathogen-free and germ-free mice, we report that probiotics significantly promote the decline of HBsAg and inhibit HBV replication by enhancing intestinal homeostasis and provoking intrahepatic interferon (IFN)-γCD4 T cell immune response. Depletion of CD4 T cells or blockage of IFN-γ abolishes probiotics-mediated HBV inhibition.

The t-SNARE protein OsSYP132 is required for vesicle fusion and root morphogenesis in rice.

Root morphogenesis is crucial for water and nutrient acquisition, but many aspects of root morphogenesis in crops are not well-understood. Here, we cloned and functionally characterized a key gene for root morphogenesis in rice (Oryza sativa) based on mutant analysis. The stop root morphogenesis 1 (srm1) mutant lacks crown roots (CRs) and lateral roots (LRs) and carries a point mutation in the t-SNARE coding gene SYNTAXIN OF PLANTS 132 (OsSYP132), leading to a premature stop codon and ablating the post-transmembrane (PTM) region of OsSYP132.

Long-term grazing changed the spatial distributions of dominant species in typical steppe of Inner Mongolia.

Dominant species occupy a pivotal role in plant community, influencing the structure and function of the ecosystem. The spatial distributions of dominant species can react to the effect of different grazing intensities, thereby reflecting their tolerance and adaptive strategies toward grazing. In this study, geostatistical methods were mainly used to study the spatial distribution characteristics of Stipa krylovii Roshev.

This study develops a series of NBI-based acidochromic AIEgens engineered for ultra-wide acidochromic scope in self-reporting soft actuators, establishing the relationship between the photophysical properties and structural configurations of the AIEgens, further investigating their acidochromic behavior and fabricating acidity monitoring chips. The acidochromic behaviors were thoroughly investigated, and high-precision acidity monitoring chips were fabricated. We confirmed the protonation order of nitrogen atoms within the molecules and elucidated the acidochromic mechanisms through DFT and H NMR analyses.

Integrated analysis reveals the immunotoxicity mechanism of BPs on human lymphocytes.

Bisphenol A (BPA) is a well-documented endocrine-disrupting chemical widely used in plastic products. In addition to its endocrine-disrupting effects, BPA exhibits immunotoxicity. Many countries have banned BPA because of its adverse effects on human health.

Adeno-associated-virus-mediated delivery of CRISPR-CasRx induces efficient RNA knockdown in the mouse testis.

In male mammals, many developmental-stage-specific RNA transcripts (both coding and noncoding) are preferentially or exclusively expressed in the testis, where they play important roles in spermatogenesis and male fertility. However, a reliable platform for efficiently depleting various types of RNA transcripts to study their biological functions during spermatogenesis has not been developed. We used an adeno-associated virus serotype nine (AAV9)-mediated CRISPR-CasRx system to knock down the expression of exogenous and endogenous RNA transcripts in the testis.

Methionine Sulfoxide Speciation in Mouse Hippocampus Revealed by Global Proteomics Exhibits Age- and Alzheimer's Disease-Dependent Changes Targeted to Mitochondrial and Glycolytic Pathways.

Methionine oxidation to the sulfoxide form (MS) is a poorly understood post-translational modification of proteins associated with non-specific chemical oxidation from reactive oxygen species (ROS), whose chemistries are linked to various disease pathologies, including neurodegeneration. Emerging evidence shows MS site occupancy is, in some cases, under enzymatic regulatory control, mediating cellular signaling, including phosphorylation and/or calcium signaling, and raising questions as to the speciation and functional nature of MS across the proteome. The 5XFAD lineage of the C57BL/6 mouse has well-defined Alzheimer's and aging states.
