Project Title: Evaluation of the therapeutic potential of non-viral apolipoprotein E gene transfer to limit progression of atherosclerosis

 

Project team:

 

Dr. Trusca Georgeta Violeta, Project Director

 

Dr. Mariana Pinteala, Mentor

 

Project summary:

 

Apolipoprotein E (apoE) has lipid-lowering and anti-atherosclerotic effects, being involved in the clearance of cholesterol-rich lipoproteins and the cholesterol efflux from cells.

 

We hypothesize that an increase in apoE expression induced by fullerene-based nanosystems will confer anti-atherosclerotic protection and contribute to the regression of atherosclerotic plaques.

 

The goal of this project is to generate fullerene-based nanoparticles conjugated with DNA encoding full length or truncated forms of apoE under CMV promoter to be used for in vivo non-viral transfection as a therapeutic tool for limiting atherosclerosis progression.

 

The specific objectives are:

 

O1. To generate non-viral transfection agents for expression of apoE3 or its fragments.

 

  • clone apoE3 or its fragments in a non-viral vector;

  • couple the obtained plasmids to C60-PEI conjugates;

  • test the functionality of C60-apoE/GFP polyplexes as non-viral transfection agents.

 

O2. To assess the timing and organs accumulation of apoE expression after in vivo transfection.

 

  • determine the organs transfected by systemic delivery of C60-apoE/GFP polyplexes;

  • test the time-course evolution of in vivo transfection with C60-apoE/GFP polyplexes.

 

O3. To evaluate the potential beneficial effects of apoE-polyplexes in experimental atherosclerosis using in vivo transfection.

 

  • to evaluate the atherosclerotic plaque evolution after systemic delivery of apoE-polyplexes in apoE-deficient mice;

  • to determine if the minimally invasive intramuscular injection of apoE-polyplexes is efficient in atherosclerotic plaque reduction in apoE-deficient mice.

The results will reveal the therapeutic potential of non-viral apolipoprotein E gene transfer in atherosclerotic plaque regression, opening new horizons in the therapy of atherosclerosis.
