Induction of CD52 expression by ATRA in NB4 cells.

(A) RT-PCR analysis of CD52 mRNA and (B) Western blotting analysis of CD52 protein induction in NB4 cells treated with ATRA at different time points. CD52 mRNA and protein were not detected in NB4 cells untreated with ATRA at 0 hours. Expression of β-actin confirmed similar loading in each lane.
