Genes of the apoptotic pathway overexpressed at least two times, or downregulated by 50%, after treatment of neuroblastoma cell lines with ATRA.

Genes significantly upregulated or downregulated more than 2-fold are represented. Asterisks indicate significant differences among control and treated cells (*, p<0.05; **, p<0.01). Lines (–) indicate that these genes were neither overexpressed at least two times, nor downregulated by 50% after the treatment.
