Targeting expression of a dominant-negative retinoic acid receptor mutant in the epidermis of transgenic mice results in loss of barrier function.

Abstract excerpt

To study the effects of retinoic acid on the skin in vivo, we have subverted the activity of endogenous receptors by targeting expression of a dominant negative mutant of retinoic acid receptor alpha (RAR alpha) to the epidermis of transgenic mice. At birth, mice expressing the mutant RAR alpha transgene exhibited a marked phenotype of a red, shiny skin that was somewhat sticky to touch. Severely affected...
