Article Abstract
(Schw.) Wolf () is valued for its nutritional and therapeutic properties. is commonly processed into slices of different shapes and sizes. We quantified alkali-soluble and water-soluble polysaccharides, total amino acids, and triterpenoids in slices of varying geometries (square: 1-9 cm width; round: 1-6 cm radii). Results showed that triterpenes and water-soluble polysaccharides initially decreased and then stabilized with increasing slice size, while total amino acids accumulated progressively, indicating spatial metabolic heterogeneity in . To map metabolite distribution, we segmented the into seven concentric zones and profiled the metabolites using a widely targeted metabolomics approach. A total of 359 metabolites were identified. The fungal symbiotic matrix exhibited metabolic profiles similar to the intermediate regions, while peripheral regions maintained comparable levels of triterpenes, saccharides, and amino acid derivatives. This study provides a detailed metabolomic blueprint of and offers insights for standardized processing and optimized medicinal use.

Tissue factor (TF) has emerged as a promising target for the diagnosis and treatment of hepatocellular carcinoma (HCC). However, there is limited data available on TF-related PET imaging for longitudinal monitoring of the pathophysiological changes during HCC formation. Herein, we aimed to explore the TF-expression feature and compare a novel TF-targeted PET probe with F-FDG through longitudinal imaging in diethylnitrosamine (DEN)-induced rat HCC.

MicroRNAs (miRNAs) are critical regulators of gene expression in cancer biology, yet their spatial dynamics within tumor microenvironments (TMEs) remain underexplored due to technical limitations in current spatial transcriptomics (ST) technologies. To address this gap, we present STmiR, a novel XGBoost-based framework for spatially resolved miRNA activity prediction. STmiR integrates bulk RNA-seq data (TCGA and CCLE) with spatial transcriptomics profiles to model nonlinear miRNA-mRNA interactions, achieving high predictive accuracy (Spearman's ρ > 0.

Morphogenetic information arises from a combination of genetically encoded cellular properties and emergent cellular behaviors. The spatio-temporal implementation of this information is critical to ensure robust, reproducible tissue shapes, yet the principles underlying its organization remain unknown. We investigated this principle using the mouse auditory epithelium, the organ of Corti (OC).

Retinal ganglion cells (RGCs) are highly compartmentalized neurons whose long axons serve as the sole connection between the eye and the brain. In both injury and disease, RGC degeneration occurs in a similarly compartmentalized manner, with distinct molecular and cellular responses in the axonal and somatodendritic regions. The goal of this study was to establish a microfluidic-based platform to investigate RGC compartmentalization in both health and disease states.

Major depressive disorder affects millions worldwide, yet current treatments require prolonged administration. In contrast, ketamine produces rapid antidepressant effects by blocking spontaneous N-Methyl-D-Aspartate (NMDA) receptor signaling, which lifts the suppression of protein synthesis and triggers homeostatic synaptic plasticity. Here, we identify a parallel signaling pathway involving metabotropic glutamate receptor 5 (mGluR5) that promotes rapid antidepressant-like effects.
