Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
During oogenesis, DNA methyltransferase 3-like (Dnmt3l) is required for the establishment of the maternal germline DNA methylation imprints that in the offspring, govern the parent-of-origin-specific expression of most known imprinted genes (Science 2001, 294:2536-9). Dnmt3l-deficient dams were crossed with wildtype sires to obtain Dnmt3l-/+ embryos that lack maternal methylation imprints. Gene expression was measured in Dnmt3l-/+ and wildtype embryos and is expected to differ for imprinted genes that are under the control of a maternal methylation mark.

Illumina HiSeq 2500
Description
We examined the kinetics of production of mRNAs and small RNAs derived from transposable elements during mouse spermatogenesis, in whole gonads of wildtype and DNA methylation-deficient males (Dnmt3L and Miwi2 mutants). We found that in absence of DNA methylation, transposon reactivation is not constitutive but rather occurs in a class- and development-specific manner : both the intensity of reactivation and the number of reactivated transposon classes increased as germ cells progress in meiosis. Moreover, we observed that transposon silencing before meiosis is not due to increased cleavage by the piRNA machinery. In contrast, the burst of transposon transcripts occurring at meiosis in the absence of DNA methylation serve as substrates for increased piRNA production Overall design: Six whole testis samples were analyzed, corresponding to three time points (16.5dpc, 10dpp and 20dpp) each for Dnamt3L-/- animals and control littermates. For 16.5dpc, testes from 7/8 mice were pooled per genotype. For the other stages, three mice were pooled per genotype.

Description
The Microrchidia (Morc) family of GHKL ATPases are present in a wide variety of prokaryotic and eukaryotic organisms but are of largely unknown function. Genetic screens in Arabidopsis thaliana have identified Morc genes as important repressors of transposons and other DNA methylated and silent genes. MORC1 deficient mice were previously found to display male-specific germ cell loss and infertility. Here we show that MORC1 is responsible for transposon repression in the male germline in a pattern that is similar to that observed for germ cells deficient for the DNA methyltransferase homolog DNMT3L. Morc1 mutants show highly localized defects in the establishment of DNA methylation at specific classes of transposons, and this is associated with failed transposon silencing at these sites. Our results identify MORC1 as an important new regulator of the epigenetic landscape of male germ cells during the period of global de novo methylation. Overall design: This data includes: 47 RNA-seq, 4 smRNA-seq, 6 BS-seq, and 2 ChIP-seq datasets

Description
RNA isolation and purification steps greatly influence the results of gene expression profiling. There are two commercially available products for whole blood RNA collection, PAXgene and Tempus blood collection tubes, and each comes with their own RNA purification method. We examined the impact of RNA isolation methods on gene expression profiles.
