Working model. Psychological stress alters gut microbial community and SCFA profiles during tumor development. Administration of Akkermansia muciniphila, butyrate or high-fiber diet markedly reverses stress-caused cancer stemness and anxiety-like behavior. Butyrate transactivates ZFP36 to accelerate LRP5 mRNA decay, thereby blocking Wnt/β-catenin signaling pathway to attenuate cancer stem-like traits.
