Expression data from gonads of Meioc+/+ and Meioc-/-mice

ABSTRACT: Meiosis is a specialized division that is specifically engaged in germ cells. This program is finely and dichotomically regulated: germ cells enter meiosis at fetal life in ovaries (13.5 dpc) and only at post-natal life in testes (8 dpp). We used microarrays to determine the gene expression modifications in Meioc mutant gonads displaying early meiotic defects. 14.5 dpc ovaries and 8 dpp testes from Meioc+/+ and Meioc-/- mice (NMRI) were dissected and processed for RNA extraction and hybridization on Affymetrix microarrays. Two pools were analysed for each genotype and each sex. We sought to constitutes pairs (A and B) of wild type and knock-out pools from embryos and pups that were homogenous for developmental stages and from matched littermates. 10 ovaries from 5 embryos composed each pool for females and 4 testes from 4 pups composed each pool for males.

Translational activation of developmental mRNAs during neonatal mouse testis development

Project description:The sequence of gene regulatory events that drive neonatal germ cell development in the mammalian testis is not yet clear. We assessed changes in mRNA utilization in the neonatal testis at 1 and 4 dpp, times when the testis contains quiescent gonocytes (1 dpp) and proliferating spermatogonia (4 dpp). There are not thought to be major changes in the nature or number of somatic cells over that interval. We used microarrays to detail the global expression levels of mRNA distribution between non-translating mRNAs and efficiently translating mRNAs during testis development at 1 dpp and 4 dpp Extracts of mouse testes from 1 dpp and 4 dpp CD-1 mice were fractionated over a sucrose gradient in triplicate. Gradients were fractionated using an ISCO gradient fractionation system equipped with a UA-6 detector. The position of the 80S peak defined the boundary between translating and non-translating mRNAs. Pooled non-polysomal (non-translating; fractions 1-3) and heavy polysomal (efficiently translating, fractions 7-13) RNAs were isolated from sucrose gradient fractions for hybridization on Affymetrix 420 2.0 microarrays.

mRNA-based generation of marmoset PGCLCs capable of differentiation into gonocyte-like cells

Project description:We developed a mRNA transfection-based method for the efficient generation of primordial germ cell like cells (PGCLCs) in marmoset. Single cell RNA-seq analyses (10X) confirmed that the induced marmoset PGCLCs show transcriptome profile similar to in vivo PGCs. For comparison we sequenced iPSCs, E74 ovaries, E82 ovaries, NB ovaries, E87 testes, and day 22 testes.

The role of MEIOC at the transition from mitosis to meiosis during mammalian spermatogenesis [bulkRNAseq]

Project description:We investigated how MEIOC affects testicular germ cells at the transition from mitosis to meiosis. We performed gene expression profiling analysis using data obtained from RNA-seq of preleptotene-enriched testes from wild-type and Meioc KO pups.

Regulatory complexity revealed by integrated cytological and RNA-seq analyses of meiotic substages in mouse spermatocytes

Project description:The juvenile onset of spermatogenesis in mice is analyzed by combining cytological and transcriptomic data in a novel computational analysis, resulting in meiotic substage-specific transcriptomes and the discovery of a transcription factor network that regulates the substages of meiosis. Germ cells from testes of individual mice were obtained at two-day intervals from 8 to 18 days post-partum (dpp), with five biological replicates at each age (samples 8_1 through 18_5). Eight stages were discriminated cytologically by combinatorial antibody labeling, and RNA-seq was performed on the same samples. A novel permutation-based maximum covariance analysis (PMCA) method was developed to deconvolve genes into meiotic substages. To verify PMCA derived pachytene/diplotene substage-specific genes, we isolated enriched populations of adult pachytene germ cells (samples rep1 through rep4), followed the same RNA-seq protocol, and compared the PMCA derived substage-specific gene lists to the genes expressed in the pachytene/diplotene enriched germ cells.

RNA-Seq of cKIT+ sorted cells from 53-137 day old fetal testes and ovaries and RNA-Seq of TRA-1-81+ H1 and UCLA1 hESCs.

Project description:We performed RNA-Seq analyses on 15 human fetal samples at 53-137 days of development, 9 female and 5 male, and identified the transcriptional changes during the transition of human cKIT+ primordial germ cells (PGCs), the precursors of gametes, to the generation of Advanced Germline Cells. Comparing the transcriptional profile of PGCs to that of H1 and UCLA1 hESCs identifies differences between the two cell types and pinpoints molecules that can be used in the development of in vitro germ cell differentiation protocols starting from human pluripotent stem cells. RNA-Seq of cKIT+ cells analyzed from 6 biological samples for testes and 9 samples for ovaries from 53-137 days. 2 biological replicates of TRA-1-81+ cells sorted from H1 and UCLA1 hESCs. WGBS of cKIT+ cells analyzed from 4 biological samples of ovaries and 1 biological sample of testes at 57-137 days of development.
