Reducing This Amino Acid May Aid In Fight Against Breast Cancer

SAN FRANCISCO, CA / April 22, 2019 / According to The American Cancer Society (ACS) breast cancer is the most common cancer in American women, except for skin cancers. Currently, the average risk of a woman in the United States developing breast cancer sometime in her life is about 12%. This means there is a 1 in 8 chance she will develop breast cancer. This also means there is a 7 in 8 chance she will never have the disease. The American Cancer Society estimates there will be about 268,600 new cases of invasive breast cancer diagnosed in women in the United States for 2019.

A new study performed by a team at Harvard Medical School has unexpectedly found that amino acid, leucine, may play a role in the formation of resistance to a certain drug, tamoxifen, that it used to treat estrogen receptor-positive (ER-positive) breast cancer.

Dr. Steven Quay, CEO of Atossa Genetics (NASDAQ: ATOS) stated, "having studied leucine metabolism for my Ph.D. in biological chemistry at the beginning of my career, this finding makes total sense. Cancer is a disease characterized by both genetic changes, that provide the "motivation" to grow abnormally, and metabolic changes, that provide the "means" to grow abnormally. Leucine sits at the hub of metabolic pathways that have broad, pleomorphic effects. This paper joins scores of others that show the powerful effects of metabolism, including diet, on cancer growth. In our research here at Atossa Genetics, we are always watching for signs of the interplay of genetics and metabolism to help inform our clinical stage, development programs for the prevention and treatment of breast cancer."
