Project description:Dmrt1 (doublesex and mab-3 related transcription factor 1) is a conserved transcriptional regulator of male differentiation required for testicular development in vertebrates. This study examines the result of conditional removal of Dmrt1 from Sertoli cells in P28 testis tissue. Testes from P28 Dmrt1 flox/flox mice were compared to testes from P28 Dmrt1 flox/flox mice with the Sertoli cell-specific Sf1 (Nr5a1; MGI:1346833) or Dhh (MGI:94891) promoters driving Cre expression.

Dmrt1 (doublesex and mab-3 related transcription factor 1) knockout expression analyses in E13.5 testes in S6 background

Project description:Dmrt1 (doublesex and mab-3 related transcription factor 1) is a conserved transcriptional regulator of male differentiation required for testicular development in vertebrates. In mice of the 129Sv strain, loss of Dmrt1 causes a high incidence of teratomas. Mutant 129Sv germ cells undergo apparently normal differentiation up to embryonic day 13.5 (E13.5), but some cells fail to arrest mitosis and ectopically express pluripotency markers. Expression analysis and chromatin immunoprecipitation identified DMRT1 target genes whose misexpression may underly teratoma formation.

Comparison of E13.5 testes gene expression between Dmrt1(+/-) and Dmrt1(-,-) animals that show high incidence of teratoma formation.
