Fungi synthesize flavonoids, but not isoflavones - a risk of feeding source contamination

This study demonstrates that reports of fungi synthesizing isoflavones are likely artifacts caused by plant-derived contaminants in culture media, as fungal genomes lack the necessary enzymatic machinery for isoflavone biosynthesis despite possessing the ability to produce simpler flavonoids via distinct evolutionary pathways.

Dietary protein source dictates the impact of obesogenic diets on hepatic steatosis and insulin resistance via carnitine-dependent regulation of acetyl-CoA carboxylase

This study reveals that dietary protein sources (pork and soy) exacerbate obesity and hepatic insulin resistance in obesogenic conditions by elevating carnitine levels, which downregulate ACC2 and alter mitochondrial lipid handling, whereas casein protein does not produce these adverse effects.

ZNF114 Promotes Gastric Cancer Progression by Inducing Epithelial–Mesenchymal Transition and Shaping an Immunosuppressive Tumor Microenvironment

This study demonstrates that ZNF114 acts as an oncogenic driver in gastric cancer by promoting epithelial–mesenchymal transition and establishing an immunosuppressive tumor microenvironment, thereby correlating with poor patient prognosis and serving as a potential therapeutic target.

Genome-wide association studies identify genetic determinants of synucleinopathy biomarkers. 

This genome-wide association study identifies both established and novel genetic variants that significantly modulate cerebrospinal fluid, plasma, and urine biomarkers in α-synucleinopathies, highlighting the critical need to account for genetic background when interpreting these biomarkers for diagnosis and therapeutic development.

Distinct macrophage- and cardiomyocyte-associated inflammatory signatures in forensic autopsy hearts with acute ischemic heart disease

This study demonstrates that analyzing the distinct, cell-type-specific inflammatory signatures of macrophage-derived osteopontin and cardiomyocyte-derived NLRP3 in forensic autopsy hearts provides valuable insights into the inflammatory microenvironment of acute ischemic heart disease, potentially aiding the diagnosis of sudden death cases with subtle pathological findings.

Evaluation of a Recombinant Multi-Epitope Sperm Protein Vaccine for Immunocontraception in Female Mice

This study demonstrates that a recombinant multi-epitope vaccine targeting sperm proteins IZUMO1, SACA3, and PH-20 effectively reduces fertility in female mice by inducing significant antibody responses that impair fertilization, all while maintaining a safe short-term histopathological profile.

Rural Living Experience as a Determinant of Rapid Naming Performance in Chinese Adults

This study demonstrates that a higher proportion of lifetime rural living experience is independently associated with reduced rapid naming performance and slower processing speed in cognitively normal Chinese older adults, highlighting a significant, underrecognized source of environmental bias in language-based cognitive assessments.

OsWD40-193 negatively regulated resistance to Hirschmanniella mucronata in Oryza sativa

This study elucidates that the transcription factor OsDERF1 enhances rice resistance to the nematode *Hirschmanniella mucronata* by repressing the expression of the negative regulator OsWD40-193, which interacts with ABF95813 to suppress resistance via the jasmonic acid signaling pathway.

Parameter-Efficient Adaptation of a Vision Foundation Model Maps the Allometric Scaling Laws of Gastric Tumor Ecology

This study demonstrates that a parameter-efficient adaptation of the MUSK vision foundation model using Low-Rank Adaptation not only achieves high diagnostic accuracy for gastric cancer in a resource-constrained Chilean cohort but also enables a novel allometric ecological framework that quantifies tumor morphotype heterogeneity while mathematically correcting for sampling biases to improve patient stratification.
