Progesterone 19-31 tumor necrosis factor Homo sapiens 139-148 16860828-8 2006 These findings demonstrate that E2 inhibits the TNF alpha-induced early apoptosis in hepatoma cells, by suppressing the oxidative stress processes, whereas progesterone acts in a manner opposite from the effects of E2, and the inhibitory effects of E2 were blocked by progesterone, thus leading to the apoptosis of hepatoma cells. Progesterone 268-280 tumor necrosis factor Homo sapiens 48-57
