Study of the Effects of Lovaza (Omega 3 Fatty Acids) On Lipoprotein Particles and Their Transcriptional Effects
High levels of triglycerides is a common abnormality found in patients with diabetes and
also cardiovascular disease, and may contribute to the risk for both. Omega 3 fatty acids,
as found enriched in fish and also in the commercial agent called Lovaza lower triglyceride
levels. Prior work from the investigators group demonstrated that an enzyme responsible for
the break down of triglycerides - lipoprotein lipase - generates molecules that can activate
a specific nuclear receptor known as PPAR-alpha. This study investigates the hypothesis that
taking Lovaza shifts the specific fatty acid content of triglyceride containing lipoproteins
and increases the ability of those lipoproteins to activate PPAR-alpha.

This study will investigate changes in lipid and other metabolic parameters as well as the
ability of isolated lipoproteins to activate PPARs in the presence or absence of lipoprotein
lipase in a cohort of normal healthy individuals with modest hypertriglyceridemia before and
after a course of Lovaza.
