Project description: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.

Project description:The meiosis-specific chromosomal events of homolog pairing, synapsis, and recombination occur over an extended meiotic prophase I. In this study, we show that, in mice, maintenance of an extended meiotic prophase I requires the gene Meioc, a germ-cell specific factor conserved in most metazoans. Using immunoprecipitation and quantitative mass spectrometry, we identify proteins that interact with MEIOC in the mouse germ line.
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.
