Existing targeting systems used to deliver chemotherapy to cancer cells cannot handle the large size of the CRISPR-Cas9, and have limited penetrance – they don’t get into enough of the target cancer cells. Their solution was to use lipid nanoparticles.
How does CRISPR help with diabetes?
CRISPR skin patches could be a needle-free way to manage type 2 diabetes. Researchers at the University of Chicago used the skin grafts on mice to reduce obesity and blood sugar levels. In type 2 diabetes, a person’s blood sugar is too high because the body either can’t make insulin or resists its effects. Insulin is a hormone that regulates blood sugar. With CRISPR, scientists modified a gene that makes a hormone needed for insulin production. They then inserted the gene into skin cells, grew the cells in the lab, and grafted the gene-altered skin onto mice. After eating a high-fat diet, mice with the CRISPR skin grafts gained less weight than a control group that didn't get the grafts. They also showed less insulin resistance, a precursor to type 2 diabetes. Xiaoyang Wu, an associate professor at the University of Chicago, says the grafts could be used for other diseases, too. For diabetic patients, he says, the biggest benefit is that they wouldn’t have to inject insulin daily.
How did CRISPR skin grafts help mice?
After eating a high-fat diet, mice with the CRISPR skin grafts gained less weight than a control group that didn't get the grafts. They also showed less insulin resistance, a precursor to type 2 diabetes.

The CRISPR mechanism would be added to “good” bacteria, or a probiotic, that a person could swallow as a pill or a liquid. Unlike antibiotics, which kill both bad and beneficial bacteria, a drinkable or edible CRISPR probiotic would be specific to a patient’s bacterial infection, only killing the harmful germs.
Does CRISPR reverse hearing loss?
Zhen-Yi Chen, an ear specialist at Harvard, is interested in whether CRISPR could reverse gradual hearing loss. Delicate hair cells in the inner ear are what pick up sound and allow us to hear. These cells can become damaged by too much exposure to loud noises or a flaw in a person’s DNA.

The first trial of CRISPR for patients with cancer tested T cells that were modified to better "see" and kill cancer. CRISPR was used to remove three genes: two that can interfere with the NY-ESO-1 receptor and another that limits the cells’ cancer-killing abilities.
Is CRISPR good for cancer?
There’s also hope that it will have a place in treating cancer, too. But CRISPR isn’t perfect, and its downsides have made many scientists cautious about its use in people. A major pitfall is that CRISPR sometimes cuts DNA outside of the target gene—what’s known as “off-target” editing.
