Figure 1. DNA binding of c-Fos and c-Jun subunits of the transcription factor AP-1 heterodimer. Binding of c-Fos (A) and c-Jun (B) to DNA. Results are presented as mean optical density (OD) ± SEM cis-UCA concentration was 100 µg/ml. Seven parallel samples were measured in control and cis-UCA, and nine parallel samples in UV and cis-UCA + UV treatments. *p<0.05; **p<0.01 (Mann–Whitney).
