(1) 慢性骨髄性白血病を発症するp210BCR/ABL トランスジェニックマウスを用いた急性転化機構の解析

 

慢性骨髄性白血病を発症したp210BCR/ABLトランスジェニックマウスでは、顆粒増殖による脾臓の腫大(白三角)と顆粒球浸潤による腸管の肥厚(矢印)を認める。また、末梢血、骨髄、脾臓では分化傾向を有する顆粒球系の細胞の増殖を認める(上図左)。慢性骨髄性白血病の急性転化遺伝子として同定したZfp423について、p210BCR/ABL単独では慢性骨髄性白血病の病理像を認めるのに対し(上図右上)、p210BCR/ABLと共にZfp423を発現させると急性転化の病理像が認められた(上図右下)
