Vit A plays a key role in human body

Vitamin A plays a more direct role than previously believed in sperm cell production, development of the central nervous system, and other vital physiological functions.

Investigators suggest that vitamin A may play a more direct role than was previously known in certain physiological functions, including sperm cell formation and the development of the central nervous system.

"Our study found that vitamin A itself is active for activating nuclear receptor TR4," said VARI Research Scientist Edward Zhou, Ph.D. "Because TR4 plays roles in sperm cell production, lipid and lipoprotein regulation, the development of the central nervous system, and the regulation of haemoglobin production in the embryo, we can imagine that vitamin A may play more important roles in human physiology than was previously believed."
