Bid‐dependent generation of oxygen radicals promotes death receptor activation–induced apoptosis in murine hepatocytes
Wen‐Xing Ding, Hong‐Min Ni, Daniell DiFrancesca, Donna B. Stolz, Xiao‐Ming Yin – 13 August 2004 – Activation of tumor necrosis factor receptor 1 or Fas leads to the generation of reactive oxygen species, which are important to the cytotoxic effects of tumor necrosis factor α (TNF‐α) or Fas ligand. However, how these radicals are generated following receptor ligation is not clear. Using primary hepatocytes, we found that TNF‐α or anti–Fas antibody–induced burst of oxygen radicals was mainly derived from the mitochondria.
