Search for signs of inflammatory disease
You fall on your shoulder and tear some cartilage, causing bone to rub against bone. Your shoulder becomes inflamed and begins to hurt because cytokine, a small signal protein secreted by your immune system, has recruited white blood cells to clean up the damage.

Obesity-related gene in mouse discovered at ORNL
Some mice born at ORNL have grown dangerously fat, even though they have been on a low-fat diet since birth. Although they do not appear overweight, these mice have a mutated gene that plays a strong role in causing obesity in the form of internal fat deposits that are hazardous to their health.

Mouse models for the human disease of chronic hereditary tyrosinemia
When a section of mouse chromosome 7 containing the coat color c gene is deleted by exposing mice to radiation, "albino" mice are born with a white, hairless coat.

Genes and proteins
Consider a living cell, the fundamental unit of life. Each human cell contains the entire human genome—some 35,000 genes. But only some genes are expressed within a specific cell, resulting in the production of specific proteins. The genes that turn on in a liver cell, for example, are different from the genes that are expressed in a brain cell.
