The combination effects index (CI) analysis confirmed the synergy of clioquinol and clofibrate on inhibiting cancer cell viability. Using inhibitors to block PPARalpha signaling diminished the synergistic cytotoxicity of clioquinol and DHA. These results provide pharmacological evidence that the synergistic anticancer action of clioquinol and DHA is mediated by PPARalpha signaling in human cancer cells. PPARalpha signaling mediates the synergistic cytotoxicity of clioquinol and docosahexaenoic acid in human cancer cells. Tuller ER, Brock AL, Yu H, Lou JR, Benbrook DM, Ding WQ.

Strictly speaking, it is not a vitamin since human skin can manufacture it, but it is referred to as one for historical reasons. It is often known as calciferol. The major biologic function of vitamin D is to maintain normal blood levels of calcium and phosphorus. Vitamin D aids in the absorption of calcium, helping to form and maintain strong bones. It promotes bone mineralisation in concert with a number of other vitamins, minerals and hormones. Without vitamin D, bones can become thin, brittle, soft or misshapen. Vitamin D prevents rickets in children and osteomalacia in adults -- skeletal diseases that result in defects that weaken bones. This book gathers international research on the leading-edge of the scientific front.
