The effects of feeding an n-3 polyunsaturated fatty acid (PUFA) rich diet on ovarian function in the Welsh mountain ewe

Polyunsaturated fatty acids (PUFA) act as precursors for prostaglandin (PG) synthesis. PGs both inhibit and stimulate ovarian steroidogenesis. We have therefore examined the hypothesis that high n-3 PUFA diets affect ovarian steroid synthesis through modulating prostaglandin synthesis.Welsh mountain ewes were individually fed a control diet or a diet containing linseed (high in n-3 PUFA) for 6 weeks. To assess the impact of the diet during differe...

Dietary polyunsaturated fatty acid supplementation in vivo modulates ovine adrenal steroidogenesis in vitro

Increased dietary intake of polyunsaturated fatty acids (PUFAs) has been reported to be associated with a decreased incidence of cardiovascular disease. Increased dietary intake of polyunsaturated fatty acids (PUFAs) has been reported to be associated with a decreased incidence of cardiovascular disease. We have recently reported that ovarian steroid synthesis in ewes fed a diet high in n-3 PUFAs is significantly compromised1. Hence in this study we have assessed th...

Polyunsaturated fatty acids in vivo and in vitro affect expression of steroidogenic acute regulatory protein in steroidogenic tissues

Public health policy in recent years has favoured a reduction in saturated fats in favour of polyunsaturated fats due to the numerous health benefits of polyunsaturated fatty acids (PUFAs). Previous studies have demonstrated that PUFAs modulate gonadal steroidogenesis. We have therefore investigated the hypothesis that PUFAs modify steroidogenesis through affecting components of the cholesterol metabolising machinery, including steroidogenic acute regulatory (StAR) protein and...
