| Outline of Final Research Achievements |
It is known that insulin resistance is increased by ingestion of trans fatty acids,but detailed biochemical analysis of the process has not been conducted. In this study with YMB-1-E and other cells, I showed the attenuation of insulin receptor and its substrate-1 proteins, the inhibition of tyrosine residue phosphorylation, the inhibition of serine residue phosphorylation of these proteins and also the enhancement of TNF-α production by elaidic acid. EPA worked inhibitory to these responses. These results suggest the possibility of improving insulin resistance by reviewing trans fatty acid intake.
