MLV integration within Zfp521. The numbers of mice with MLV integration are presented. In the vertical sequence of Zfp521, underlines represent the four oligonucleotides duplicated by the integration in the host cell genome when the integration occurs at p, q, r, s, or t. There were mice that have more than one integration sites in the lymphoma tissue genome. The r and s positions are shared by hematopoietic tumor of SL/Kh and AKXD strains. Four integration site data are added to our previously data. A hotspot ‘s’ consists of two nucleotide nucleotides G and C.^{45, 55}
