Many years of research by Animatus' scientists have given us a deep understanding of cardiac developmental biology. We have applied this expertise to develop technology that can control networks of genes to regenerate cardiac tissue.

A messenger RNA directs a cell to make a specific protein. Our mRNAs are modified to make altered proteins which regulate key cellular pathways in cardiac cells.

 

These mutant proteins, when expressed in a cardiac cell, cause activation of gene networks that drive production of many stem cell proteins that rejuvenates injured heart tissue.

 

Unlike normal adult cardiac cells, the reprogrammed cardiac stem cells can replicate and replace cells injured by a heart attack. Once the mmRNA has decayed, the stem cells will revert to a normal cardiac cell type and restore the function of the heart.

 
 

How will the mRNA be administered to a patient?

 

The mRNA will be injected directly in the heart via a catheterization procedure that is similar to those performed in hospitals thousands of times a year.

Future Research Directions

Heart Related

  1. Heart Failure in aging without mycardial infarction.

  2. Hypoplastic Left Heart Syndrome - congenital underdevelopment of the left ventricle in newborns. Can be addressed with regenerative mmRNAs. 

  3. Cardiac arrythmias - Animatus has technology to reprogram adipose (fat) stem cells using mmRNAs to electrically conductive heart cells that can replace faulty cells that cause arrythmias.

Non Heart Related

  1. The same gene networks that reprogram heart cells also exist in other tissues in the body, such as blood vessels, skeletal muscle,liver, nerves, pancreas, intestine, skin, immune cells and lung. Therefore, these same mmRNAs that work in the heart could potentially be used to regenerate these tissues as well.

  2. Modifications to mRNAs discovered by Animatus could target any therapeutic mRNA to a specific tissue. This would mean that an mRNA could be administered systemically and produce an effect only in the targeted tissue.
