A new study published in the journal Nature found that Asparagine, an amino acid found in asparagus and many other foods, was shown aid in the spread of breast cancer to other organs of the body in mice. The researchers said that when a diet in asparagines was introduced to the animals, the number of malignant tumors outside of the breast tissue like those found in the bones, lungs, and brain.
The number one cause of death in people with breast cancer — decreased dramatically. The lead author of the study Greg Hannon, told The Guardian “This is a very promising lead and one of the very few instances where there is a scientific rationale for a dietary modification influencing cancer.”
An elementary unit, Asparagine, for proteins made in the body but is also an amalgam found in dairy, whey, beef, poultry, eggs, fish, seafood, potatoes, legumes, nuts, seeds, soy and whole grains. The study said that the research team was able to block asparagine in the mice through a drug known as L-asparaginase and by removing most of the compound from their diets.
Then the doctors checked records of former breast cancer patients who died of the disease and found that those with multiple other tumors caused from their breast cancers also had the highest levels of asparagine.
It comes out hat asparagine makes cancer cells easily transportable through the bloodstream and helps them to evolve and spread to other organ and grow into new tumors, according to the study. The further step of the study is to see if the findings in mice transpose to people.
Chief executive of Breast Cancer Now, Baroness Delyth Morgan, told: “This early discovery could offer a long-awaited new way to help stop breast cancer spreading — but we first need to understand the true role of this nutrient in patients.”
