Although these peptides are still under investigation and not approved for human use, research models suggest several potential biological roles
Pharmacological agents such as fenofibrate, carnosine, umbelliferone, paricalcitol, leonurine, triptolide, DDO-1039, and Potentilla Discolor Bunge(whose main active components are quercetin, kaempferol, and -sitosterol) can upregulate NRF2, thereby suppressing ferroptosis and decelerating the progression of diabetic nephropathy [118,119,120,121,122,123,124,125,126]
Therefore, the tissue-specific effects of l-carnitine are likely to be different among species, and thus more low-carnitine animal models should be established to intensively evaluate the possible different functions of l-carnitine among species
