Results of a preclinical study offer hope for new treatment options in the medium term ovarian cancer is often very aggressive and responds poorly to the therapies currently available. A recent study offers hope that this could change in the medium term. The researchers used an mRNA as a therapeutic. With its help, the tumor cells produced a protein again that prevents their own uncontrolled proliferation or induces cell death. The mRNA therapeutic successfully combated cancerous cells and tumors in vitro as well as metastases in mice.
