| Research Abstract |
The relation between taurine and obesity was investigated. Taurine is by de novo synthesis : it is metabolized by cysteine dioxygenase (CDO). Anti-obesity mouse models (fish oil fed mice, Conjugated linoleic acid-supplemented mice) up-regulated CDO mRNA in white adipose tissue with increase of body weight and body fat. And, we created transgenic mice that overexpressed CDO in white adipose tissues (FAT-CDO) and examined whether taurine had anti-obesity effect. CDO mRNA levels in FAT-CDO transgenic mice were higher than the level in wild type mice (2-3 fold higher). However, blood taurine levels were similar in FAT-CDO transgenic mice and wild type mice. FAT-CDO transgenic mice did not decreased body weight and body fat. Furthermore, we examined the blood taurine levels in 44 obese patients. There was no correlation between obesity and blood taurine level. However, blood taurine level slightly increased after treatment of obesity.
These data indicate that obesity is relation to taurine synthesis in fat tissue. Further analysis of the taurine status in human obesity is important.
