Abstract
The embryonal carcinoma cell line P19 undergoes terminal differentiation upon induction by retinoic acid (RA). The effects of RA on the retinoic acid receptor (RAR) mRNA level were investigated in P19 cells and an RA non-responsive mutant RAC65. RA induced a rapid accumulation of RAR alpha within 2 h and this was followed by an increase in the RAR beta mRNA. RAC65 cells differed from P19 cells in that the accumulation of RAR alpha mRNA was delayed and that an aberrant pattern of RAR alpha transcript was observed.
