Both CBD and CBG induced apoptosis in all three mesothelioma cell lines which corresponded with expression changes in intrinsic apoptotic pathway genes, including increased expression of BBC3 (which encodes BCL2 binding component 3) and decreased expression of BIRC5 (encoding baculoviral inhibitor of apoptosis (IAP) repeat containing 5). Here, BIRC5 is linked to mesothelioma.
