But since asparagine may be synthesized in the body, dietary restrictions may need to be accompanied by drugs that interfere with the metabolic pathways that give rise to the amino acid.The link between asparagine and the spread of breast cancer was explored by a multicenter study that used in vitro and in vivo models of tr
