Compositions, methods, kits and systems for cancer treatment and metabolic intervention therapy
The present disclosure provides compositions and methods for treating cancer with nutritionally modified diets and/or dialysis treatment, such as through amino acid depletion of one or more nonessential amino acids. In some aspects, the present disclosure provides compositions and methods for treating obesity with such modified diets and/or dialysis treatment. Furthermore, in some aspects, the present disclosure provides compositions and methods for treating renal disease with such modified diets and/or dialysis treatment.
