DIXDC1 Promotes Lymphatic Metastasis and Resistance to Cuproptosis in Bladder Cancer Through Mediating DLAT

open access: yesAdvanced Science, EarlyView.
DIXDC1 drives bladder cancer progression by binding and stabilizing DLAT. This axis enhances NEK7 and CCNE2 mRNA stability to promote proliferation and lymphatic metastasis, while limiting copper‐induced DLAT oligomerization to reduce cuproptosis sensitivity, identifying DIXDC1 as a potential target linking metastasis with cuproptosis resistance ...

Hierarchical Flux‐Protection Engineering Stabilizes Oxidation‐Prone Metabolic Nodes for High‐Level Curcumin Biosynthesis

open access: yesAdvanced Science, EarlyView.
Flux‐protection engineering stabilizes an oxidation‐prone L‐DOPA node in engineered E. coli by combining acid‐adapted chassis evolution, respiratory‐chain modulation, enzyme‐level flux matching, and pH–DO control. Carbon is redirected from oxidative browning to productive biosynthesis, enabling 1075.2 mg/L curcumin and demonstrating transferability to ...

Delay of Cucumber Senescence and Life‐Extending Capabilities on Caenorhabditis elegans With the Postharvest Application of Sorbitol and Methyl Salicylate

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
Methyl salicylate and sorbitol were taken as coating agents. Caenorhabditis elegans was taken as an animal model. The coated agents were applied in C. elegans. The life span study in C. elegans proves the authenticity of MS and SL. MS and SL extended the post‐harvest life of cucumber for 14 days.
