ChIP-qPCR analysis of RARα recruitment at the Cy26a1 gene promoter.

(A) Kinetic ChIP experiments performed with RA-treated MCF7 and BT474 cells and determining the recruitment of RARα to the R1 and R2 response elements of the Cyp26a1 gene. Values correspond to a representative experiment among 3. (B) ChIP experiments performed with MEFs expressing RARαWT or RARαS77A and determining the recruitment of RARα to the R1 and R2 elements of the Cyp26a1 gene. Values are the mean ±SD of three experiments.
