revolutionary crispr based genome editing system treatment destroys cancer cells

Sumary of Revolutionary CRISPR-based genome editing system treatment destroys cancer cells:

  • Researchers at Tel Aviv University (TAU) 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..
  • Dan Peer, VP for R&D and Head of the Laboratory of Precision Nanomedicine at the Shmunis School of Biomedicine and Cancer Research at TAU..
  • The results of the groundbreaking study, which was funded by ICRF (Israel Cancer Research Fund), were published in November 2020 in Science Advances..
  • “This is the first study in the world to prove that the CRISPR genome editing system can be used to treat cancer effectively in a living animal,”.
  • The molecular scissors of Cas9 cut the cancer cell’s DNA, thereby neutralizing it and permanently preventing replication.”.
  • Glioblastoma is the most aggressive type of brain cancer, with a life expectancy of 15 months after diagnosis and a five-year survival rate of only 3%..
  • Ovarian cancer is a major cause of death among women and the most lethal cancer of the female reproductive system..
  • Treatment with CRISPR-LNPs in a metastatic ovarian cancer mice model increased their overall survival rate by 80%..
  • “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…
