Neuroblastoma causes alterations of the intestinal microbiome, gut hormones, inflammatory cytokines, and bile acid composition

Abstract

The present study provides a first glimpse that human NB in a murine model induces tumor cachexia associated with alterations in metabolic and inflammatory parameters, as well as changes in the intestinal microbiota. Since the intestinal microbiome is known to contribute to the host's ability to harvest energy, a favorable modulation of the intestinal microbiome in tumor patients could potentially represent a novel therapeutic target to prevent tumor-associated cachexia.
