Androgenic control of acetate incorporation into membrane lipids in rat ventral prostate.

The rat ventral prostate plasma membranes incorporated acetate into total lipids, which was a time-dependent process. The acetate incorporation was mainly into phospholipids followed by cholesterol. The main phospholipids subclasses were choline and ethanolamine glycerophospholipids. Castration modified drastically both cholesterol-phospholipids and choline glycerophospholipids-ethanolamine glycerophospholipids ratios. These effects of castration were reversed after testosterone treatment, which could suggest an influence of this hormone in the modification of some lipid classes into cellular membrane.
