| Outline of Final Research Achievements |
TRAIL is a cytokine which can induce apoptosis against cancer cells and contribute to cancer prevention. We examined whether the decline of immunity due to diabetes resulted in the down-regulation of TRAIL expression causing subsequent carcinogenesis.
We compared the expression of TRAIL mRNA of the organ samples from a type 2 diabetes model of the rat and mouse with those from normal animals. As the results, TRAIL expressions of cDNA samples derived from large intestine and pancreas of the diabetes model animals were lower than those from normal animals. On the other hand, a diabetes therapeutic drug metformin enhanced the TRAIL sensitivity for several human pancreatic cancer cells.
