neoplasm
N
• pIpC-treated mice do not develop leukemia
• pIpC-treated mice infected with a retrovirus expression a truncated form of Notch1 that is constitutively cleaved in a ligand-independent manner or a Notch1 lacking the PEST domain exhibit shorted latency to development of leukemia

hematopoietic system
N
• pIpC-treated mice exhibit normal numbers of hematopoietic stem cells and are more functionally competent than in cells from Fbxw7tm1Iaai/Fbxw7+ Tg(Mx1-cre)1Cgn mice

immune system
N
• pIpC-treated mice exhibit normal numbers of early T cell progenitors in the thymus
