Relative luciferase activities driven by sequences encompassing Sox9 ChIP-seq binding sites. Results are presented as the enhancement of luciferase activity in the presence of a SOX9 expression vector (SOX9 (+)) compared with an empty vector (SOX9 (−)). All results are normalized to the luciferase activity of Renilla luciferase control reporter vector. Experiments for each construct were performed in four replicates in duplicate wells. Mean ± SE; *P < 0.05, **P < 0.01 by t test . N.S. not significant
