Since demonstrating that both Bac and SynB1 enhanced ELP tumor deposition, we assessed the potency of both Bac-ELP-H1 and SynB1-ELP-H1 in vitro against several malignant glioma cell lines of human and rat origin, all of which express c-Myc [24], [25], [31]. Here, NR5A1 is linked to malignant glioma.
