RELA and neuroblastoma: Transfection of the p65 gene significantly upregulated the expression of Fas and PVR in all NB cells (Figure 1A,B), with the exception of Fas in SK-N-AS, and of both Fas and PVR in the SK-N-BE(2)c cell line, in agreement with the loss of FAS and PVR genes as revealed by a-CGH analysis (Table 1).
