Research advances in the association between gut microbiota imbalance and colorectal cancer / 中华临床营养杂志

ABSTRACT

Colorectal cancer (CRC) is a malignant digestive tract tumor resulted from genetic and environmental factors and can be accompanied by a series of gene mutations.The etiology of CRC,particularly the role of gut microbiota imbalance,has became a hot research topic along with the increase of its prevalance.In this article,we elucidate the potential roles and mechanisms of streptococcus gallolyticus,fusobacterium,Escherichia coli,Bacteroides fragilis,and helicobacter wlori in the development of CRC,with an attempt to further understand the functions of microbiota,search for possible specific carcinogenic strains,and improve the management of CRC.
