Lipid accumulation inhibition strategies alleviate Fusobacterium nucleatum-infected colorectal cancer.

ABSTRACT:

Background

Fusobacterium nucleatum (F. nucleatum) is prevalent in colorectal cancer (CRC), and it can promote proliferation and induce chemoresistance via multiple pathways. The development of treatment strategies for F. nucleatum-infected CRC is of great importance.

Methods

Shotgun metagenomic and metabolomic analyses of human feces, as well as metabolomic analysis of human blood, were performed to reveal the dysbiosis and metabolic dysregulation in CRC. Furthermore, the effects of Bifidobacterium animalis (B. animalis) on F. nucleatum and CRC were assessed in vitro and in vivo. Using a mouse CRC model, the function of bile salt hydrolase (BSH) in B. animalis was verified through heterologous expression in Escherichia coli (E. coli). Bile acids and drug library screening ex
