A Natural Sweetener‐inducible Genetic Switch Controls Therapeutic Protein Expression in Mammals

Advanced Science, EarlyView.
This study develops a natural sweetener, the psicose‐inducible transgene expression (PURE) system based on an Agrobacterium tumefaciens–derived transcriptional repressor PsiR. The PURE system is highly specific to psicose, being insensitive to other sugars and structurally similar molecules.

Colorectal Cancer Cell's Weapon: RNF32 Engages SPP1+ Macrophages to Foster Liver Metastasis, Targeted by Indole‐3‐Acetic Acid

Advanced Science, EarlyView.
Cytoplasmic RNF32 fuels CRC liver metastasis by degrading GSK3β, which stabilizes β‐catenin and activates Wnt/EMT. Moreover, RNF32 rewires the metastatic niche: it depletes CD8+/CD4+ T and NK cells while recruiting SPP1+ macrophages (which boost tumor stemness via CD44), fibroblasts, and immunosuppressive monocytes to aid colonization.
