Effect of Daikenchuto On Spontaneous Intestinal Tumors in Apc Min/+ Mice
2021
Daikenchuto (TU-100) is herbal medicine which predominantly contains ginger, Japanese pepper, and ginseng. We investigated whether TU-100 can affect the composition of gut flora and intestinal tumor development using ApcMin/+ mice, a murine model of intestinal tumor. Bacterial 16S rRNA sequencing and short-chain fatty acid analysis were performed on faecal samples. Tumor number and size were analysed. Any change in gene expression of the tumor tissues was assessed by real-time PCR. Principal coordinate analysis (PCoA) showed that the faecal microbiota cluster of TU-100-fed mice was different from the microbiota of control mice. However, no significant difference was observed in the concentration of short-chain fatty acids, tumor number, and gene expression levels between the two groups. Our data showed that TU-100 can affect the intestinal environment; however, it does not contribute in tumor progression or inhibition in our setting.
