| Research Abstract |
This study was performed to examine why the anti-tumor effect of vitamin B6 is profound in the colon. This reason was explained by indicating the higher sensitivity of colon levels of B6-vitamers to dietary supplemental vitamin B6. Further study with animals and colon cancer cells was conducted to examine the gene expression in response to vitamin B6. The results indicated the vitamin B6 altered the expression of genes relating to mast cells and cytotoxicT-cell activity and cytoprotection, which may lead to the anti-tumor effect
