The results of the oligoarray data were validated by quantitative real-time RT-PCR, using three genes relevant to apoptosis: I) Proapoptotic genes: TNFRS1A and TRADD which are both the key genes that start the apoptotic cascade when induced in cancer cells, II) Antiapoptotic genes: MCL-1 and LTBR which both have versatile roles in regulation of apoptosis and cell cycle progression. Here, TRADD is linked to cancer.
