MicroRNA expression profile of fibro-adipogenic progenitors in Duchenne muscular dystrophy reveals dysregulation of adipogenesis-related microRNAs

This study characterizes the dysregulated microRNA profile of fibro-adipogenic progenitors in Duchenne muscular dystrophy patients, identifying hsa-miR-196a-5p as a novel regulator that inhibits adipogenic differentiation by suppressing key adipogenic and HOX genes.

Association Between a Standardized Digit-Comparison Task and Reading Comprehension in Japanese Schoolchildren With Adequate Decoding

This study found that performance on standardized digit-comparison tasks is significantly associated with reading comprehension in Japanese schoolchildren with adequate decoding abilities, independent of general cognitive ability and decoding skills, suggesting these tasks may offer complementary insights for evaluating reading difficulties in this population.

Proteomic analysis reveals a 4-methylumbelliferone-induced metabolic shift accompanied by reduced CD147 expression and MMP-2 activity in U937 cells

This study reveals that 4-methylumbelliferone (4MU) exerts antitumor effects in AML U937 cells through a novel hyaluronic acid-independent mechanism involving metabolic reprogramming toward oxidative phosphorylation, downregulation of CD147 expression, and reduced MMP-2 activity.

Effects of Microplastics and Chromium in Marine and Freshwater Microalgae

This study demonstrates that the combined exposure of microplastics and hexavalent chromium causes significantly greater physiological damage and growth inhibition in freshwater *Scenedesmus* sp. compared to the more resilient marine *Chlorella* sp., highlighting the synergistic ecotoxicological threat of these co-contaminants and the utility of microalgae as bioindicators.

Biological soil crusts and slope gradient synergistically regulate the community structure and functional differentiation of nitrogen-cycling microorganisms in alpine meadow soils

This study demonstrates that biological soil crusts and slope gradients synergistically regulate the community structure and functional differentiation of nitrogen-cycling microorganisms in alpine meadows by altering soil organic matter and ammonium nitrogen, thereby enhancing nitrification and driving distinct microbial adaptation strategies across different slope conditions.

Advanced modelling of RYR1-related myopathies using human iPS cells and 3D engineered skeletal muscles

This study establishes a humanized disease modeling platform using patient-derived iPSCs and 3D engineered skeletal muscles to demonstrate that specific gain-of-function RYR1 variants recapitulate key pathological features of RYR1-related myopathies, including altered myofiber morphology and disrupted excitation-contraction coupling, thereby providing a vital tool for precision medicine and therapeutic development.
