The pathogenesis of cancer is closely related to the disruption homeostasis in human body. gut microbiome plays crucial roles maintaining its host throughout lifespan. In recent years, a large number studies have shown that dysbiosis involved entire process initiation, development, and prognosis by influencing immune system metabolism. Some specific intestinal bacteria promote occurrence development cancers under certain conditions. Conversely, some other suppress oncogenesis progression cancers, including inhibiting delaying boosting therapeutic effect on cancers. promoting effects been comprehensively discussed previous review. This article will review latest advances mechanisms suppression, providing new perspective for developing strategies prevention treatment.

Patients with breast cancer (BC) who benefit from the PD-1/PD-L1 inhibitor (PDi) is limited, necessitating novel strategies to improve immunotherapy efficacy of BC. Here we aimed investigate inhibitory effects flaxseed lignans (FL) on biological behaviors BC and evaluate roles FL in enhancing anticancer PDi. HPLC was used detect content enterolactone (ENL), bacterial transformation product FL. Transcript sequencing performed identified CD38 as a downstream target gene ENL. CD38-overexpressing cells were constructed cell proliferation, colony formation, wound healing transwell assays assess function ENL/CD38 axis vitro. Multiplexed immunohistochemistry (mIHC) CyTOF changes tumor immune microenvironment (TIM). 16S rDNA explore gut microbiota mice. A series vivo experiments conducted mechanisms converted ENL by administration inhibited progression malignant downregulating CD38, key associated immunosuppression blockade resistance. The mIHC assay revealed that enhanced CD3+, CD4+ CD8+ reduced F4/80+ TIM. confirmed regulatory combination PDi (FLcPDi) In addition, analysis demonstrated FLcPDi treatment significantly elevated abundance Akkermansia and, importantly, response mice treated antibiotics. FL/ENL/CD38 progression. modulating host immunity.
