Abstract
Colorectal cancer (CRC) is a prevalent malignant tumor that poses a significant threat to human health; however, the precise mechanism underlying its onset remains elusive. In this study, we utilized metagenomic sequencing to reveal the dysregulation of intestinal microbiota caused by CRC. Single-cell sequencing data showed elevated mRNA expression of methyltransferase-like protein 3 (METTL3) in CRC, which was correlated with the abundance of intestinal microbiota. Furthermore, we found that METTL3 promotion of CRC progression is microbiota-dependent. Using induced METTL3fl/fl Vil1-cre+/- mice, we identified the microbiota regulated by METTL3 in CRC. Our research indicates that METTL3 leads to high expression of HIF1α, which promotes the expression of lipocalin 2 (LCN2) in CRC cells, inhibiting the abundance of Akkermansia muciniphila, thereby promoting CRC progression.
