| Abstract | |
We treated rats for 7 days with subcutaneous soybean (SB) oil or sunflower (SF)oil injections. Insulin resistance was developed, with a decrease in GLUT4 quantity and translocation in adipose tissue in the rats treated with those oils, despite GLUT4 mRNA increase in muscle and adipose tissue. Sunflower treatment led to decrease in GLUT1mRNA in adipose tissue, where NF- <font face=\"symbol\">kB mRNA was also decreased (other transcriptional factors did not change: PPAR<font face=\"symbol\">g, MEF2A e MF2D). Fatty acids were measured in the plasma, the liver (no changes), muscle (palmitoleic increased in SF, linolenic decreased in SB and SF and arachidonic increased in SB) and adipose tissue (palmitic and stearic increased and linoleico decreased in SB and SF, besides increasing in saturated/ unsaturated ratio.
