“In combination with high glucose, palmitate induced increased shunting of excess glucose , increased mitochondrial reactive oxygen species production and an elevation in many transcription-related proteins.”
“In INS-1 β-cells, 0.4 mM palmitate with 5 mM glucose increased the levels of dihydrosphingosine and dihydroceramides, two lipid intermediates in the de novo biosynthesis of ceramides, without inducing apoptosis.”
“Reduction of plasma FFA levels in fasted rats or humans severely impairs glucose-induced insulin release but palmitate can augment insulin release in the presence of nonstimulatory concentrations of glucose.”
“The apoptotic percentage of endothelial cells treated with high levels of glucose plus FFAs was significantly higher than that treated with high concentration of glucose or FFAs ( PA and/or OA) alone.”
