Researchers at Karolinska Institutet in Sweden report in the journal
Nature that they have developed novel first-in-class inhibitors that compromise mitochondrial function in cancer cells. Treatment with the inhibitors stopped cancer cells from proliferating and reduced tumour growth in mice, without significantly affecting healthy cells.
"We are excited to have shown that this novel principle for cancer treatment works in animal models and hopefully the inhibitors can now be developed further for anti-cancer treatment in humans," says Nils-Göran Larsson, professor at the Department of Medical Biochemistry and Biophysics at Karolinska Institutet, who led the study.
Mitochondria are the power plants of our cells. They are essential for converting the energy in the food we eat into the common energy currency that is required for a variety of cellular functions. Cancer cells are critically dependent on mitochondria, not only for providing energy but also for producing a variety of building blocks needed to make more cells as the cancer cells divide. The continuous cell division means that a cancer cell must constantly make new mitochondria in order to grow.
