چکیده

How is retinoic acid produced? In vertebrates, vitamin A, in the form of retinyl esters, is stored mainly in the liver as well as in the lungs, kidneys and bone marrow. Retinol, bound to the retinolbinding protein (RBP), enters the circulatory system in order to reach cells that require retinoic acid. The retinol–RBP complex enters the cells through the RBP receptor (STRA6). Within the cells, retinol is metabolized in a reversible step to retinal by the retinol or alcohol dehydrogenases (RODHs or ADHs) and then in an irreversible manner to retinoic acid by the retinal dehydrogenases (RALDHs). In the cytoplasm, retinoic acid is associated with the cellular retinoic acidbinding protein (CRABP).

The effect of bilateral intrahippocampal injection of all–trans retinoic acid on spatial learning in adult male rats.

Introduction: Previous studies have shown that vitamin A and its derivatives such as retinoid and all-trans retinoic acid have a crucial role in memory, learning and synaptic plasticity. The receptors of vitamin A are seen in different parts of the brain such as hippocampus, where vitamin A has an important role in learning. In this study, the effect of intrahippocampal (CA1) injection of al...
