Evidence suggests these dual pathways create enhanced effects on both homeostatic and hedonic appetite systems in the hypothalamus, hindbrain, and septum, producing greater metabolic benefits than either agent individually
Several amino acids had their concentrations increased following MTX treatment: glycine, alanine, phenylalanine, threonine, histidine, valine, arginine, leucine, isoleucine, tyrosine, and proline
Because so many pathways are implicated at once, most research protocols isolate a small panel of markers, such as collagen I/III ratios or a single antioxidant enzyme, rather than tracking every reported change simultaneously
