Core Tip

Core Tip: Deng et al explores the role of gut microbiota and metabolites in colorectal cancer (CRC) metastasis using 16S rRNA sequencing and liquid chromatography-mass spectrometry-based metabolomics. It identifies significant differences in microbial communities and metabolites between metastatic and non-metastatic CRC patients. The findings suggest that specific microbial taxa and metabolites may contribute to metastasis progression, offering potential biomarkers for diagnosis and treatment. Despite some limitations, such as small sample size and cross-sectional design, the study provides valuable insights into the microbiota-metabolite axis and its potential for therapeutic targeting in CRC.
