Chronic exposure to peroxisome proliferators in rodents leads to deposition of lipofuscin and eventually to liver tumors, most probably a consequence of oxidative stress leading to DNA damage (Evans and Lake 1998)
Both of these processes are mainly regulated by the signaling pathway: insulin-like growth factor-1 (IGF-1) phosphoinositide-3-kinase (PI3K) protein kinase B (Akt) mammalian target of rapamycin (mTOR)

Indications and Usage: L-Carnitine Injection is indicated for the treatment of carnitine deficiency syndromes, including primary systemic carnitine deficiency, secondary carnitine deficiency, and certain metabolic disorders such as mitochondrial disorders and fatty acid oxidation disorders
- L-Carnitine is studied in research models involving fatty acid transport, mitochondrial energy metabolism, exercise-related pathway research, metabolic flexibility, cellular energy production, and cardiometabolic signaling
The local maxima at 366 nm, 288 nm and 243 nm are due primarily to the Pteroic acid, benzamide / phenol and thiazole-amide substructures, respectively, although the molecule contains dozens of chromaphores with overlapping absorption in the UV region
