Transcriptome profiling of normal and DNMT3L-overexpressing human neurons [RNA-seq]

ABSTRACT: The objective of this study is to test the gene expression changes caused by DNMT3L overexpression in human neurons. The total RNA of each sample was extracted from the lentivirus infected, early differentiated human neuroprogenitors with ZsGreen (n=3) or DNMT3L (n=3) overexpression by using TRIzol reagent. Then the RNA samples were processed for high throughput transcriptome sequencing on Illumina HiSeq 3000 platform. Results: among 57 905 cleaned RNAs, 7983 RNAs were differentially expressed in DNMT3L overexpressing neurons compared with control neurons, with q-value ≤ 0.05. After limited the cut-off by adding |fold change| ≥ 1.5, the numbers of differential expressed RNAs lowered to 1073, with more down-regulation (590) than up-regulation (483). The differential expressed genes distributed in all chromosomes, also showing the pattern of more down-regulation than up-regulation in every chromosome except chromosome 21. Functional annotation with DAVID revealed the top functional groups including type I interferon signaling pathway and RNA and protein processing.

Project description:Genome wide DNA methylation profiling of cultured fetal human neurons infected with lentivirus carrying DNMT3L or ZsGreen genes for 4days. The Illumina Infinium 850k Human MethylationEPIC BeadChip was used to obtain DNA methylation profiles across approximately 850,000 CpGs in the infected cells. Samples included 3 control samples (ZsGreen) and 3 DNMT3L-overexpressing samples (DNMT3L).

Transcriptome profiling of wild type and DNMT3L-overexpressing Drosophila larvae brains

Project description:The objective of the study was to examine the gene expression changes caused by human DNMT3L overexpression in Drosophila melanogaster brains. There were 6 samples in total- C1, C2, C3, D1, D2, and D3. C1-C3 were larvae brains from the strain of elavC155-Gal4, which were used as the control group (C). D1-D3 were larvae brains from the strain with DNMT3L overexpression, which were bred by crossing the strains of elavC155-Gal4 and w/w;P(UAS-DNMT3L,w+)/Cyo;TM2/TM6B and used as the DNMT3L overexpressing group (D). The total RNA of each sample was extracted from 30 brains of the 3rd instar larvae of Drosophila by using TRIzol reagent. Then the RNA samples were processed for high throughput transcriptome sequencing on Illumina HiSeq 3000 platform. Results: among 17737 cleaned RNAs, 267 RNAs were differentially expressed in DNMT3L overexpressing group compared with control group, with q-value ≤ 0.05 and |fold change|≥2 , with more down-regulation (151) than up-regulation (116). They corresponded to 655 human homologous genes. The differential expressed genes distributed in all chromosomes. Functional annotation with GO and KEGG enrichment revealed the top functional groups including calcium ion transport, voltage gated channel, choilnergic synapse, serotonergic synapse, and drug metabolism.

DNA methylation changes in Dnmt3L-deficient mouse embryonic stem cells (mESCs)

Project description:We used RRBS to analyze DNA methylation in mESC lines deficient for maternal Dnmt3L (Dnmt3L mKO), zygotic Dnmt3L (Dnmt3L KO), and both maternal and zygotic Dnmt3L (Dnmt3L mzKO). Compared to wild-type (WT) mESCs, Dnmt3L mKO mESCs exhibit severe loss of methylation at imprinted loci but no changes in global DNA methylation, Dnmt3L KO mESCs exhibit moderate loss of methylation at many Dnmt3a target regions but do not affect methylation at imprinted loci, and Dnmt3L mzKO mESCs exhibit combined changes of mKO and KO cells, with severe loss of methylation at imprinted loci and moderate loss of methylation at Dnmt3a target regions.

Genome-wide analysis of Dnmt3L heterozygous and wildtype spermatocytes and spermatids

Project description:Comparison of gene expression differences between Dnmt3L heterozygous and wildtype pachytene spermatocytes, and similarly between Dnmt3L heterozygous and wildtype round spermatids which were isolated from the Dnmt3L knockout mouse line. This array was conducted to address the hypothesis that Dnmt3L heterozygosity results in deregulated gene expression within spermatocytes and spermatids. Results show that Dnmt3L heterozygosity causes numerous genes to be differentially regulated on a genome-wide level, showing that DNMT3L has an important role in regulating gene expression within these male germ cells.

Identification of FMRP targets in human neural progenitors and neurons

Project description:We identified FMRP-bound RNAs in hPSC (human pluripotent stem cells)-differentiated forebrain neuroprogenitors (NPCs) and neurons using crosslinking immunoprecipitation (CLIP) coupled to high-throughput sequencing. We examined transcriptomic and proteomic changes in FMRP-KO NPCs and neurons.

Dnmt3l-/+ (maternal methylation-deficient) vs normal 8.5dpc embryos

Project 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. Keywords: genetic modification, DNA methylation
