The specific thing they need dino DNA for in rebirth (spoilers)

So I didn't see anyone talking about the variety article on rebirth, but it seem that the specific thing that is the reason they need the dino DNA is - last chance for spoilers -

Heart diseases. Interested to see how dino blood can help that. Specific quote:

"Johansson now leads “Jurassic World Rebirth” as Zora Bennet, a former mercenary now leading a group of scientists on a mission to retrieve dinosaur blood that could lead to the cure for heart disease. "
