Hormonal derangements almost invariably anticipate and signal the onset of tumors. Chronic, nocturnal melatonin administration delays aging in normal strains of mice. On the contrary it promotes and accelerates the onset of tumors in the cancer-prone strain of C3H/He mice. Grafting of a young pineal gland into aging mice prolongs their longevity and maintains juvenile circadian hormonal functions while pinealectomy (Px) does the opposite. We investigated if Px in C3H/He mice would modify their congenitally deranged pituitary function and affect their longevity. It was found that contrarily to Px in normal mice, Px in C3H/He mice remarkably maintains juvenile night levels of thyroid hormones and lipids, preserves a cell-mediated immune response and significantly prolongs their life. The pineal gland and its pathology may be the key for understanding, not only the causes of metabolic aging, but also the origin of those congenital or progressive aging-related hormonal alterations preceding onset of all tumors and thus allow preventive corrective interventions with pineal-derived agents.
