MCA 129 fibrosarcoma and B16F1 melanoma grown in apoptosis resistant
acid sphingomyelinase (asmase)-deficient or Bax-deficient mice
Reduced tumor endothelial apoptosis in asmase -/-
mice. Tumors grew 2-4 x faster than in the wild-type.
Tumors with apoptosis-resistent vascular endothelium
were resistant to radiation
