Sympathoadrenal cervical ganglions prepared from BMCC1 transgenic mice undergo accelerated apoptosis induced by withdrawing NGF, and BMCC1 is expressed in neuronal cells in which programmed cell death was induced by retinoic acid and NGF withdrawal.16 To understand the molecular role of BMCC1 in this process, we treated NB cells with DNA-damaging reagents. Here, NGF is linked to neuroblastoma.
