The observation that HDL cholesterol did not increase in ApoC - III — treated mice would seem to support an LPL - independent mechanism as well, although the absence
of cholesterol ester transfer protein in mice confounds this finding.
«For example, HDL and LDL themselves are comprised of hundreds of molecular species
of cholesterol esters and triglycerides.

The findings make evacetrapib the third failure in a class
of drugs known as cholesteryl
ester transfer protein (CETP) inhibitors, which are designed to disrupt the natural process by which HDL
cholesterol is converted into LDL
cholesterol in the body.
These studies will investigate the consequences
of ApoF knockdown on
cholesterol disposition in an animal model, quantify ApoF levels in human subjects and identify lipoprotein properties that cause ApoF to bind and subsequently inhibit cholesteryl
ester transfer protein activity, and investigate the molecular mechanisms controlling ApoF gene expression.
ApoF is a regulator
of cholesteryl
ester transfer protein, which in turn is a major regulator
of the distribution
of cholesterol between low and high density lipoproteins.
After adjustment for intake
of meat, beer, potatoes, root crops, and vegetables the associations were weakened, but significant inverse associations remained between 15:0 in serum
cholesterol esters and body weight and BMI (data not shown).
Both ApoC - III — depleted TRLs and ApoC - III — bearing TRLs had equal amounts
of TGs, free
cholesterol, cholesteryl
esters, and [3H] retinol when normalized to protein (Supplemental Figure 7).
Nevertheless, when the fatty acids in their serum
cholesterol esters were analyzed, omega - 3 (EPA and DHA) levels were high and, more importantly, the omega - 6 / omega - 3 ratio was very low, owing to the low intake
of linoleic acid (an omega - 6 fatty acid present in the oil
of most seeds and nuts, who decreases the EPA and DHA status).
The chemical analysis
of the atheroma shows that the fatty acids from the
cholesterol esters are 74 % unsaturated (41 % is polyunsaturated) and only 24 % are saturated.
