New cancer treatment like using ‘small scissors’ to target cells

Israeli researchers say they have created a way to treat cancer in mice that is so accurate that it is like using “small scissors” to target the cells, according to a report.

“This is the first study in the world that proves that the CRISPR editing system, which works by cutting DNA, can be used effectively to treat cancer in an animal,” Professor Dan Peer, a cancer expert from Tel Aviv University, told the Times. of Israel.

Peer’s research was published last week in the journal Science Advances.

“There are no side effects and we believe that a cancer cell treated this way will never become active again.” Peer told the news outlet, adding: “This technology can extend the life expectancy of cancer patients and we hope to one day cure the disease.”


Peer said he hopes the method can one day replace chemotherapy treatment.

“If we can use this technology, we can destroy a tumor in three treatments. This technology can physically cut the DNA of cancer cells, and these cells will not survive, ”Peer said.

The research uses genome-editing technology using targeted lipid nanoparticles for cancer treatment.

The researchers used the technique on hundreds of mice – and Peer said the method could potentially be used on humans within two years.

The study focused on two types of cancers – glioblastoma, an aggressive cancer that can occur in the brain or spinal cord, and metastatic ovarian cancer.

Researchers found that cancer-treated mice had twice the life expectancy of the control group and their survival rate was 30 percent higher, the news committee reported.

“The technology needs to be further developed, but the most important thing is that we have shown that this can kill cancer cells,” said Peer.
