| abstractText | Experimental testicular teratomas (ETTs) can be induced in 129/Sv mouse by E12.5 fetal testes transplant into adult testes. Previously, we conducted linkage analysis to explore candidate genes possibly involved in ETT development using F2 intercross fetuses derived from F1[LTXBJ Ã 129/Sv- + /Ter (+ /+)] hybrids. By linkage analysis on Chr 18 and Chr 19, we identified the genomic locus for experimental testicular teratoma 1 (ett1) on Chr 18. In the present study, we conducted additional mapping and linkage analysis on teratoma susceptibility and genome composition on Chr 1-17. The results revealed two new candidate loci, experimental testicular teratoma 2 (ett2) and experimental testicular teratoma 3 (ett3), on Chr 3 and 7. Interestingly, the rates of ETT generation were increased in the case of ett2 and ett3 regions replaced with LTXBJ strain. To determine whether a polymorphic gene was present, we performed exome analysis of 129/Sv- + /Ter (+ /+) and LTXBJ. This revealed the presence of SNPs in all three loci, ett1 to ett3. ett1 contains polymorphic Mc4r; ett2 contains polymorphic Polr3c, Cd160, and Pdzk1; and ett3 contains polymorphic Prmt3. We found additional loci responsible for ETT formation, namely, ett2 and ett3, and identified candidate genes in these regions by exome analysis. |
