1 Suppression of NF-kappaB activity by parthenolide induces X-ray sensitivity through inhibition of split-dose repair in TP53 null prostate cancer cells. parthenolide nuclear factor kappa B subunit 1 Homo sapiens
2 We have shown that parthenolide, a sesquiterpene lactone, is a radiation sensitizer for human CGL1 hybrid cells that have constitutively activated NF-kappaB and wild-type p53. parthenolide nuclear factor kappa B subunit 1 Homo sapiens
3 We hypothesized that inhibition of NF-kappaB activity by parthenolide was responsible for the observed X-ray sensitization and inhibition of split-dose repair. parthenolide nuclear factor kappa B subunit 1 Homo sapiens
4 Inhibition of NF-kappaB activity by knockdown of p65 increased radiation sensitivity and completely inhibited split-dose repair in both cell lines in a nearly identical manner as parthenolide treatment alone. parthenolide nuclear factor kappa B subunit 1 Homo sapiens
5 We propose that the suppression of radiation-induced NF-kappaB activity by parthenolide leads to X-ray sensitization through inhibition of split-dose repair in p53 null PC-3 prostate cancer cells. parthenolide nuclear factor kappa B subunit 1 Homo sapiens
