Is conversion of solid into more anoxic ascites tumors associated with p53 inactivation?

Abstract excerpt

Most solid tumors are unable to grow in the ascites form, unless selected by prolonged serial transfer of peritoneal fluid (Klein, 1955). Established ascites tumor cells grow under highly crowded, virtually anoxic conditions (Warburg and Hiepler, 1953). Hypoxia was recently identified as a powerful inducer of p53 dependent apoptosis (Graeber et al., 1996). We wished to examine whether the conversion of relatively...
