Fatty acids are critical for normal fetal development, but may also influence placental function. We have previously reported that oleic acid (OA) stimulates amino acid transport in primary human trophoblast (PHTs) cells. In other tissues, saturated and unsaturated fatty acids have distinct effects on cellular signaling, for instance palmitic acid ...

Diets high in saturated fatty acids (SFAs) are associated with the development of circadian dysregulation, obesity, and type 2 diabetes mellitus. Conversely, polyunsaturated fatty acids (PUFAs) have recently been identified to improve insulin sensitivity, reduce weight gain, and relieve obesity-induced inflammation. While saturated fatty acids, such as the prevalent dietary ...
