abstractText | Mice of the C57BL/6J inbred strain develop thymic lymphomas at very high frequency after acute gamma-irradiation, while mice of several inbred strains derived from the wild progenitor of the Mus spretus species and their F1 hybrids with C57BL/6J appear extremely resistant. Analysis of the genetic determinism of the gamma-radiation-induced thymic lymphoma (RITL) resistance with the help of inter-specific consomic strains (ICS), which carry a single introgressed Mus spretus chromosome on a C57BL/6J genetic background, provide significant evidence for the existence of a thymic lymphoma resistance (Tlyr1) locus on chromosome 19. The subsequent analysis of the backcross progeny resulting from a cross between consomic mice heterozygous for the Mus spretus chromosome 19 and C57BL/6J mice, together with the study of inter-specific recombinant congenic strains (IRCS), suggest that this Tlyr1 locus maps within the D19Mit60-D19Mit40 chromosome interval. In addition to the discovery of a new locus controlling RITL development, our study emphasizes the value of ICS and IRCS for the genetic analysis of cancer predisposition. doi:10.1038/sj.onc.1205846 |
