Abstract:

The essential trace element selenium and polyunsaturated fatty acids (PUFA) have been used for the prevention of cancer. Both nutrients enhance the apoptosis of malignant cells and provide health benefits. However, an increased dietary intake of PUFA augments the susceptibility of lipid peroxidation and oxidative damage in many cells. So far, relatively few data are available about the interaction of selenium and PUFA in testis and thus a possible effect of both dietary components on the prevention of testicular cancer or on the apoptosis of testicular germ cells. Male germ cells in the rat contain most of the testicular phospholipid hydroperoxide glutathione peroxidase (PHGPx), mainly as the mitochondrial isoform of this selenoprotein (m-PHGPx). An experiment was therefore carried out to determine the action of fish oil, a nutrient rich in PUFA, on the testicular expression of PHGPx. Because the PHGPx formation remains nearly unchanged in the animals fed the PUFA-enriched diet, we conclude that no apoptosis of testicular germ cells is induced by an increased intake of this nutrient. The intake of fish oil in the selenium-deficient animal led to a markedly altered formation of several selenium-containing proteins, including sperm nuclei glutathione peroxidase (snGPx), also designated as the nuclear form of PHGPx (n-PHGPx), and a 10-kDa selenium-containing protein.
