What does KIRAN MUSUNURU research?

Kiran Musunuru studies innovative ways to deliver therapies to the liver, particularly targeting genetic conditions such as familial hypercholesterolemia, where cholesterol levels become dangerously high due to genetic factors. He works with a technique known as base editing, a form of CRISPR technology, which allows specific changes to DNA. This is crucial for creating new treatment avenues for patients who may not respond to standard therapies due to their unique genetic makeup. By using specially designed lipid nanoparticles, he has improved the effectiveness of these therapies, ensuring they can reach the liver cells more successfully.

Key findings

  • The new delivery method increased liver editing efficiency from 5% to 61% in certain monkeys.
  • This treatment led to a reduction in a specific cholesterol-related protein by up to 89% after six months.
  • The research highlights a potential alternative treatment for patients with homozygous familial hypercholesterolemia, who can't use traditional therapeutic methods.

McDermott-Roe C, Lv W, Shao Y, Hoshino A, Arany Z +1 more

Plain English
This study looked at how the gene Retinoic Acid Receptor Alpha (RARA) and a protein called SPNS1 affect heart damage caused by the chemotherapy drug doxorubicin (DOX).
