Project description:To explore the possible changes of gene expression induced by a carcinogen, we treated wild-type and Dicer1-KO mice with one dose of 120 mg/kg N-ethyl-N-nitrosourea (ENU), a model genotoxic carcinogen, and vehicle control. The gene expression profiles were assessed in the mouse livers in wild-type and Dicer1-KO mice design. Total RNA were isolated from the livers at days 15 after the treatment and their expression was determined using Gene Array. Gene expression in treated wild-type and Dicer1-KO mice was measured at 15 days after exposure to one dose of 120 mg/kg N-ethyl-N-nitrosourea (ENU). Each treatment duplex ,Drug-ko-a,Drug-ko-b,Drug-wt-a,Drug-wt-b,Control-ko-a,Control-ko-b,Control-wt-a,Control-wt-b.
Project description:To identifiy stage-dependent genes in Sertoli cells, we performed expression microarray analysis of the adult whole testes, cultured primary Sertoli cells, Sertoli cells directly isolated from wild-type and Nanos3 (germ-less) testes,seminiferous tubules at stages I-III, IV-VI, VII-VIII and IX-XII. Next to examine the relationship between stage-dependent gene expression change and retinoic acid signaling, we performed expression microarray analysis of the cultured primary Sertoli cells treated with retinoic acid and stage-specific seminiferous tubules injected with lentivirus containing Venus or dominat negative form of RARa, a dominant receptor for retinoic acid in Sertoli cells. Biological duplicates were examined at each sample
