The inhibition of ATM with caffeine, KU-55933, or can block siRNA or inhibition of the MEK / ERK activation of NF-kB LDRinduced and remove the survival advantage of LDR-induced. Interestingly, a study of new networks or regulatory NFkappaB Rel that NF-kB in the regulation of ATM has been associated.
Here we have shown that the ATM expression by NF-kB regulated through a direct connection to ATM promoter ARQ 197 Tivantinib and inhibition of NF-kB has to be entered Born a lower Ma at ATMs. This transcriptional regulation of ATM by NF-kB shows a new mechanism linking ATM expression radioresistance in LMP1 positive NPC. So it is tempting to suggest that the acquisition of radio-resistance in NPC by LMP1 activation of NF-kB, which binds directly to the ATM gene promoter and increased Ht H He caused the expression of ATM, to an increased Hten radioresistance.
