Replacing microRNA for cancer treatment

Inserting a missing molecule in mice may shrink liver tumors or limit their growth

It’s a simple idea: Treat cancer by finding out what’s absent in a cancer cell and replacing it.

Teeming with tumors: In mice with liver cancer, a microRNA called miR-26a stops or reduces the growth of tumors. On the left, livers taken from mice with liver cancer that did not receive miR-26a are ridden with tumors.
