IGF-1, 1,25 (OH)2 Vitamin D, and Prostate Cancer
Abstract
High circulating levels of insulin-like growth factor 1 (IGF-1) or low levels of 1,25(OH)2 vitamin D (1,25(OH)2D) are associated with an increased risk of prostate cancer. This project examines whether specific dietary patterns are related to prostate cancer by influencing levels of IGF-1 and 1 ,25(OH)2D; specifically whether high energy and protein intakes increase IGF-1 and high intakes of calcium, phosphorus, and animal protein decrease 1 ,25(OH)2D levels. The relationships between dietary factors and circulating IGF-1 and 1,25(OH)2D are being examined using the Massachusetts Male Aging Study, for which dietary data and blood samples have already been collected.
