11.   Still in their infancy, these promising vaccines attack the abnormal proteins in cancer cells.

12.   The other hypothesis holds that cells are destroyed by an abnormal protein generated inside the cells.

13.   This K-ras gene initiates production of an abnormal protein that causes lung cells to become malignant.

14.   They used genetic engineering to add human genes for sickle hemoglobin to some animals, producing transgenic mice that produce the abnormal human protein.

15.   Two reports published in the journal Cell describe how an abnormal protein accumulates inside the nucleus of key brain cells that help control body movement.

16.   When the abnormal protein gets into the brain of a healthy human or animal, it interacts with and converts normal prions into its own form.

17.   A mutated gene can create an abnormal protein, setting off a chain reaction that ends in disease.

18.   Chronic myeloid leukemia is caused by an abnormal protein that leads to a huge increase in the number of white blood cells in the body.
