Core Tip

Core Tip: This study investigated the alterations in the fecal metabolome and intestinal bacteria, and elucidated the correlations among differential metabolites, distinct bacterial taxa, and serum indicators. By employing non-targeted liquid chromatography-mass spectrometry and high-throughput DNA sequencing technologies, the researchers discovered that three Kyoto Encyclopedia of Genes and Genomes pathways, namely retinol metabolism, steroid hormone biosynthesis, and ascorbate and aldarate metabolism, were significantly enriched by differential metabolites, along with three representative bacterial genera: Streptococcus, Veillonella, and Lachnospira. Notably, Streptococcus and Veillonella exhibited evident correlations with serum indicators and differential metabolites. The findings suggest that the fecal metabolome and the composition of intestinal bacteria hold considerable potential as biomarkers for the diagnosis of hepatocellular carcinoma.
