We assessed, in this study, the effects of PPARα deficiency on the expression of mRNAencoding for insulin gene transcription factors in pancreatic β-cells along with thoseimplicated in inflammation in adipose tissues. On fasting, the adult PPARα-null mice werehypoglycemic. Serum insulin concentrations and its pancreatic mRNA transcripts weredownregulated in PPARα-null mice, suggesting that PPARα gene deletion contributes to lowinsulin gene transcription. The PPARα gene deletion downregulates the mRNA expression ofinsulin gene transcription factors, i.e., Pdx-1, Nkx6.1 and MafA. Besides, the pancreaticfunction was diminished by PPARα deficiency as PPARα-null mice expressed low pancreaticGlut…
Lack of Correlation of Plasma HDL With Fecal Cholesterol and Plasma Cholesterol Efflux Capacity Suggests Importance of HDL Functionality in Attenuati…

A number of clinical findings suggested HDL-raising as a plausible approach to treat residual risk of CVD. However, lack of CVD risk reduction by elevated HDL cholesterol (HDL-C) through cholesterol ester transfer protein (CETP) inhibition and enhanced risk reduction in apolipoprotein A-I Milano (apoAI-M) individuals with low HDL-C shifted the focus from HDL-C level to HDL function. In the present study, we investigated correlations between HDL-C, HDL function, fecal cholesterol excretion, and ex vivo plasma cholesterol efflux capacity (CEC) in animal models using two HDL modulators, LXR and PPAR-α agonists. In C57Bl mice, LXR agonist, T1317, raised HDL-C by 30%, while PPAR-α agonist, fenof…
