Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare small non-coding RNA profiling (snRNA-seq) in WT oocyte, sperm and 2PN stage embryos to those sperm and 2PN stage embryos derived from WT, Dicer cKO and Drosha cKO. We further study the roles of sperm-borne small RNA on fertilization and pre-implantation embryonic development. Methods: Small RNA profiles of adult wild-type (WT) oocytes, adult WT sperm, 2PN stage embryos, adult Dicer cKO/Drosha cKO sperm, 2PN stage embryos were generated by deep sequencing in duplicate, using Ion Torrent Proton. The sequence reads that passed quality filters were analyzed at the small RNA level with two methods: Burrows–Wheeler Aligner (BWA) followed by ANOVA (ANOVA) and TopHat followed by Cufflinks. Results: Using an optimized data analysis workflow, we mapped about 30 million sequence reads per sample to the mouse genome (build mm9) and identified 16,014 small RNA (miRNA and endo-siRNA) in the oocyte, sperm and 2PN stage of WT and Dicer cKO/Drosha cKO mice with BWA workflow and 34,115 transcripts with TopHat workflow. Approximately 47% of the miRNAs showed differential expression between the WT and Dicer cKO sperm, ~52% of miRNAs were shown dysregulated in Drosha cKO sperm compared to those in WT sperm with a fold change ≥2.0 and p value <0.05. Data analysis with BWA and TopHat workflows revealed a significant overlap yet provided complementary insights in transcriptome profiling. Conclusions: Our study represents the first detailed analysis of small non-coding RNAs (miRNAs) in sperm and demonstrated that sperm-borne small RNAs are important for fertilization and early embrynic develoment, with biologic duplicates, generated by RNA-seq technology. The optimized data analysis workflows reported here should provide a framework for comparative investigations of small RNAs profiles in mouse sperm, oocytes and 2PN stage of embryos. Our results show that NGS offers a comprehensive and more accurate quantitative and qualitative evaluation of small RNA contents within sperm or oocytes/embryos. We conclude that RNA-seq based small RNAs characterization in gametes would expedite genetic network analyses and permit the dissection of complex biologic functions during fertilization and embryonic development.

Project description:The goal of small RNA-seq is to identify the differentially expressed small RNAs (microRNA, 22G RNA, piRNA, snoRNA) in the wild-type (WT) and hrde-1 mutant of C.elegans at the normoxia reared and hypoxia treatment conditions at P0 generation, and those small RNAs maintained dysregulation in F1, F2 and F3 generation.

Project description:We report high resolution transcriptome-wide RNA cytosine methylome of Mouse Embryonic Fibroblasts (MEFs) revealed by an optimized new RNA bisulfite sequencing approach. Comparison of RNA methylation profile from wild-type and Dnmt2 -/- MEFs shows that only C38 in three tRNAs (tRNA-Asp, Gly and Val) is the target of Dnmt2 in MEFs at normal conditions. Harvested MEFs, from 13.5 isogenic (wt or Dnmt2-/-) embryos, were subjected to total RNA isolation and DNase treatment. Small RNA fraction was separated using mirVana kit (Ambion). Large RNA fraction was prepared by ribosomal RNA depletion using RiboMinus™ Transcriptome Isolation Kit (Invitrogen) followed by RNA fragmentation using RNA Fragmentation Reagent (Ambion). Each one of the fractions (small or large) from each one of the samples (wt or Dnmt2-/-) were split into two: one for direct RNA sequencing and one for RNA bisulfite sequencing. For bisulfite treatment, small and large RNA fractions of each sample (wt or Dnmt2-/-) were separately subjected to bisulfite treatment. Total of 8 samples (bisulfite treated and untreated of small and large RNA fractions of wt or Dnmt2-/-) were separately subjected to library preparation with Illumina’s directional mRNA-Seq sample preparation protocol followed by 101 cycle single-end high-throughput sequencing using Illumina’s HiSeq 2000 sequencing system.
