The functions of vitamin A are mediated by all-trans-retinoic acid, which, by binding specific nuclear transcription factors, (retinoid receptors) regulates the expression of several hundred genes [15,16,17,18,19]. Vitamin A-regulated genes are involved in fundamental biological activities, playing an important role in supporting vision, growth, cell, and tissue differentiation, haematopoiesis and immunity.
