Israeli scientists have made yet another breakthrough in the treatment for cancer. This time it is TAU which developed a system that utilizes genome editing for the care of brain and ovarian cancer patients.
Researchers at Tel Aviv University have demonstrated that the CRISPR/Cas9 system is very effective in treating metastatic cancers, a significant step on the way to finding a cure for cancer. The researchers developed a novel lipid nanoparticle-based delivery system that specifically targets cancer cells and destroys them by genetic manipulation. The system, called CRISPR-LNPs, carries a genetic messenger (messenger RNA), which encodes for the CRISPR enzyme Cas9 that acts as molecular scissors that cut the cells’ DNA.

“The CRISPR genome editing technology, capable of identifying and altering any genetic segment, has revolutionized our ability to disrupt, repair or even replace genes in a personalized manner,” said Prof. Peer. “Despite its extensive use in research, clinical implementation is still in its infancy because an effective delivery system is needed to safely and accurately deliver the CRISPR to its target cells. The delivery system we developed targets the DNA responsible for the cancer cells’ survival. This is an innovative treatment for aggressive cancers that have no effective treatments today.”
“We now intend to go on to experiments with blood cancers that are very interesting genetically, as well as genetic diseases such as Duchenne muscular dystrophy,” says Prof. Peer. “It will probably take some time before the new treatment can be used in humans, but we are optimistic. The whole scene of molecular drugs that utilize messenger RNA (genetic messengers) is thriving – in fact, most COVID-19 vaccines currently under development are based on this principle. When we first spoke of treatments with mRNA twelve years ago, people thought it was science fiction. I believe that in the near future, we will see many personalized treatments based on genetic messengers – for both cancer and genetic diseases. Through Ramot, the Technology Transfer Company of TAU, we are already negotiating with international corporations and foundations, aiming to bring the benefits of genetic editing to human patients.”
