Project description:2C embryos were generated from Kdm1a FL/Fl Zp3Cre females mated to wild type males for RNA-seq analysis using the Nugen Ovation RNA-seq system V2. Ovulated eggs from Kdm1a FL/Fl Zp3Cre females were isolated for RNA-seq analysis using the Nugen Ovation RNA-seq system V2.
Project description:We compared gene expression from 2C::tomato+/- ES cells from Kdm1a wt and mutant ES cultures 2C::tomato- samples 1, 5, 9 2C::tomato+ samples 2, 6, 10 We collecteded 3 replicates of RNA from 2C::tomato+ and - ES cells
Project description:We have identified eukaryotic translation initiation factor 4E family member 1B (Eif4e1b) as a regulator of maternal RNA translation, whose maternal deletion leads to 2-cell arrest phenotype in mouse embryos. eIF4E1b protein binds mRNA selectively in oocytes and controls their translation in early embryos. We aim to profile the global changes in protein expression in metaphase II (MII) eggs and zygotes collected from control or Eif4e1b knockout female mice. An encapsulated proteomic-sample processing protocol is used to perform this low-input mass spectrometry to quantify proteomic changes (Kulak et al. 2014/PMID 24497582).
Project description:Microarray analysis of zygotic gene expression in 2-to-3 hour wild-type (wt) and smg mutant embryos. Expression is relative to mature, stage 14 oocytes, which contain the full maternal pool of mRNA. Strictly maternal genes that are not transcribed at the MZT contribute approximately 80% of transcripts in early embryos, and are not shown. Class I zygotic genes showed high levels of expression in 2-to-3 hour embryos. 142 of the 166 Class I genes were not expressed in smg mutants. The remaining zygotically expressed genes were also present in oocytes. These genes were divided into two classes, based on analysis of 4-to-6 hour old unfertilized eggs (4-6h unf), which are transcriptionally inactive. Class-II genes produce maternal transcripts that are stable in unfertilized eggs and show significantly increased expression in 2-to-3 hour post-fertilization embryos. 358 of 395 Class-II genes require SMAUG for zygotic expression. Class-III genes produce maternal transcripts that are degraded in unfertilized eggs and show significantly increased expression in 2-to-3 hour post-fertilization embryos. 65 of 408 Class-III genes require SMAUG for expression in 2-to-3 hour embryos.
