Transgenic overexpression of a dominant negative mutant of FADD that, although counterselected during tumor progression, cooperates in L-myc-induced tumorigenesis.

Abstract excerpt

Activation of the so-called death receptors, e.g., CD95/Fas/Apo-1, is a potent stimulus to trigger apoptosis. Overexpression of the C-terminal FADD deletion mutant FADD-DN blocks death receptor-induced apoptosis, but despite this antiapoptotic activity, lck FADD-DN transgenic mice do not develop lymphomas. To analyze whether functional inactivation of FADD cooperates with Myc overexpression in tumorigenesis, lck...
