Differential expression of the alpha and beta retinoic acid receptors in tissues of the rat

Biochem J. 1989 May 1;259(3):917-9. doi: 10.1042/bj2590917.


We have compared the expression of alpha and beta retinoic acid receptors (RAR-alpha and RAR-beta) in different rat tissues. The two cDNA probes for RAR-alpha and RAR-beta each specifically detect two different transcripts. RAR-alpha was expressed in all tissues examined, but, in contrast, the expression of RAR-beta was undetectable in some tissues. The data do not support the idea that RAR-beta is specific to epithelial tissues.
