RELATED TERMS--------------------------------------
Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.
Anemia
Anemia is a condition in which a deficiency in the size or number of erythrocytes (red blood cells) or the amount of hemoglobin they contain limits the exchange of oxygen and carbon dioxide between the blood and the tissue cells. Most anemias are caused by a lack of nutrients required for normal erythrocyte synthesis, principally iron, vitamin B-12, and folic acid. Others result from a variety of conditions, such as hemorrhage, genetic abnormalities, chronic disease states or drug toxicity.

EMSY
A novel protein that connects the familial and sporadic forms of breast cancer and ovarian cancer. Some cases of breast and ovarian cancer are familial and strike women in the same family who have a heritable mutation of a gene called BRCA2 that is involved in DNA repair. However, these genetic cases are in the minority. Most cases of breast and ovarian cancer are sporadic. They occur in women with no family history of these cancers. In sporadic breast and ovarian cancer, EMSY is amplified and overexpressed. EMSY suppresses the activity of the BRCA2 gene. The overlap between sporadic EMSY amplification and familial BRCA2 deletion implicates a BRCA2 pathway in sporadic breast and ovarian cancer. EMSY connects sporadic breast and ovarian cancer to BRCA2.
