PPARD and neoplasm: Tumor growth was initially indistinguishable in Pparb+/+ and Pparb−/− mice, buthalted after approximately 2 weeks selectively in the Pparb−/− mice(Figure 1), while the inoculated Pparb+/+ mice invariably succumbed to their tumors within 2-3 weeks, the Pparb−/− miceexhibited a survival rate of >90% after six months.
