Abstract |
We have investigated the effects of hyperthermia on the apoptosis induced by tumor necrosis factor alpha (TNF-alpha). Confluent monolayers of human gastric cancer cell line MKN45 were either treated or untreated with hyperthermia for 1 h. The cells were subsequently stimulated with TNF-alpha. A 24-h incubation with TNF-alpha did not affect cell viabilities; however, pretreatment with hyperthermia significantly enhanced the level of apoptosis induced by TNF-alpha. Pretreating MKN45 cells with hyperthermia (42.0 degrees C) significantly inhibited the TNF-alpha-induced increase in the binding activity of NF-kappaB to DNA. This study suggests that hyperthermia can inhibit the TNF-alpha-induced NF-kappaB activation and that hyperthermia renders human gastric cancer cells susceptible to the TNF-alpha-induced apoptosis, possibly via inhibition of the NF-kappaB pathway.
