However, taking advantage of the fact that concomitant deletion of RIPK3 fully prevents skin lesion formation in mice with keratinocyte-restricted FADD knockout (FADDE-KO) (Bonnet et al., 2011), we generated Sharpincpdm/cpdm;Ripk3−/− mice that also lacked FADD specifically in keratinocytes (Figure 2). The gene discussed is FADD; the disease is neoplasm.
