Activation of the endocytosis pathway stratifies subtypes and therapeutic sensitivity in colorectal cancer

This study demonstrates that endocytosis pathway activity varies across colorectal cancer molecular subtypes, correlates with key oncogenic signaling networks, and that low expression of the core adaptor AP2M1 specifically predicts improved survival in metastatic patients treated with anti-EGFR therapy, suggesting its potential as a biomarker for therapeutic stratification.

Desflurane induces cognitive dysfunction in Alzheimer's disease mice via downregulation of hippocampal Syntaxin 1A

This study demonstrates that desflurane exacerbates cognitive dysfunction and amyloid pathology in Alzheimer's disease mice by downregulating and altering the phosphorylation of hippocampal Syntaxin 1A, a deficit that can be reversed by STX1A overexpression, highlighting it as a potential therapeutic target for preventing anesthetic-induced neurocognitive disorders.

The Effects of High Carbonate Alkalinity under Low Salinity on the Survival, Physiological Metabolism, and Redox Homeostasis of Crassostrea hongkongensis

This study demonstrates that high carbonate alkalinity under low salinity significantly reduces survival and induces metabolic depression, feeding compensation, and redox-energy remodeling in the Hong Kong oyster (*Crassostrea hongkongensis*), providing a theoretical basis for managing saline-alkaline aquaculture environments.

Single-cell and multi-layer analysis identifies state-restricted stromal remodeling in steroid-associated osteonecrosis of the femoral head

This study employs a multi-layer analytical strategy to reveal that stromal remodeling in steroid-associated osteonecrosis of the femoral head is a state-restricted, context-sensitive process where adipogenic rewiring is only partially coupled to a specific stress-adaptation program, rather than a uniform compartment-wide phenotype.

A genetically marked maggot to better understand corpse decomposition ecology

This study successfully developed a genetically marked *Phormia regina* blow fly strain expressing a fluorescent protein that retains normal development rates, thereby overcoming the technical barrier of tracking known-age larvae in the field to validate forensic age-estimation methods under realistic decomposition conditions.

Paenibacillus spp., a novel potato endophyte, adapts its physiology in planta to establish mutualistic symbiosis with potato

This study characterizes the newly identified potato endophyte *Paenibacillus* sp. ST1, demonstrating how its physiological adaptations to the host environment enable stable colonization, improved plant growth, and enhanced viral tolerance through a mutualistic symbiosis.
