AF1q has a precise oncogenic function. The purpose of this study is to investigate whether CBD has an effect on the AF1q/ICAM-1 regulatory axis in Burkitt’s lymphoma (BL), and thus has potential to enhance immunotherapy and reduce side effects.
We established BL cell lines with altered AF1q expression using lentivirus. After confirmation of gene expression by RT-PCR, cells were treated with CBD followed by co-culture of killing assay.
AF1q increased oncogenic growth and colony formation, and induced resistance against cell-mediated cytotoxic chemotherapy through attenuation of ICAM-1 expression in BL. CBD was able to reverse the acquired resistance mediated by AF1q/ICAM-1 regulatory axis.
CBD holds potential to enhance the efficacy of immunotherapy for BL with hyperactive AF1q/ICAM-1 regulatory axis, and warrants further study.
