| Outline of Final Research Achievements |
In this study, to elucidate the molecular mechanism of exercise on improvement of obesity and related diseases, we studied using TLR5 deficient (KO5) mice.
As results, voluntary exercise for 20 weeks decreased fat mass in epididymal and lipid droplets in liver on KO5 mice. In adipose tissues, the mRNA expressions of Atg5 and Atg7 were significantly enhanced by voluntary exercise, although LC3b mRNA was downregulated. The LC3-Ⅱ/LC3-Ⅰ ratio in adipose tissues attenuated in that of WT mice by voluntary exercise but enhanced in that of KO5 mice. Voluntary exercise decreased microbiota diversity and Firmicutes phylum related to obesity on KO5 mice. However, there were no significant correlations between autophagy-related proteins and Firmicutes or Bacteroidetes phylums.
