Tissue explant co‐culture model of the hypothalamic‐pituitary‐gonadal‐liver axis of the fathead minnow (Pimephales promelas) as a predictive tool for endocrine disruption
Endocrine disrupting compounds (EDCs) can impact the reproductive system by interfering with the hypothalamic‐pituitary‐gonadal (HPG) axis. While in vitro testing methods have been developed to screen chemicals for endocrine disruption, extrapolation of in vitro response to in vivo action shows inconsistent accuracy. We describe here our tissue co‐culture of the fathead minnow (Pimephales ...

Introduction to Lipogenesis, Lipid Anabolism and Catabolism
Sources of Fat Fat, also known as triglyceride, is made by condensing one molecule of glycerol and three fatty acids. The source of fatty acids in the body: one is the body's own synthesis, and the other is the food supply. Some unsaturated fatty acids cannot be synthesized by the body and depend on food supply, called essential fatty acids. There are mainly two kinds, one is the ω-3 series ...
