Tumor hypersialylation drives immunosuppression and limits immunotherapy efficacy by shielding tumor cells and engaging inhibitory immune receptors. Here, we engineered Escherichia coli Nissle 1917 (EcNΔpgi-SAS) as a metabolically confined “desialylation catalyst” to remodel the tumor microenvironment. This strain comb...

Platinum-based drugs are clinically vital for cancer treatment but suffer from off-target cytotoxicity and poor tumor penetration. To overcome these limitations, we designed a tumor-targeted Pt(IV) drug-bacteria conjugate (Pt-EcN-HER2). This conjugate exploits the inherent tumor tropism of probiotic bacterium Escherich...

It is demonstrated that copper-associated oxidative perturbation modulates the DNA-binding activity of CtsR through a conserved cysteine residue, consistent with a copper-associated Cys37-dependent redox mechanism potentially coupling metal homeostasis, oxidative stress, and proteostasis regulation in S. aureus.
