Figure 2. PAX3-FOXO1 regulates a RASSF4 5′ enhancer.
(A) A putative PAX3-FOXO1 binding site 5′ to the RASSF4 gene on human chromosome 10. Figure derived from publically available data in ref. 33. (B) PAX3 and PAX3-FOXO1 directly regulated the RASSF4 5′ enhancer. RD cells were cotransfected with Renilla, a luciferase vector lacking an enhancer, or the RASSF4 5′ enhancer, along with vector, wild-type PAX3, or PAX3-FOXO1. *P < 0.001 compared with vector-expressing cells; #P < 0.005 compared with PAX3-expressing cells.
