We demonstrate that dCas9-SunTag-DNMT3A dramatically increased CpG methylation at the HOXA5 locus in human embryonic kidney 293T cells (HEK293T). Furthermore, using a single sgRNA, dCas9-SunTag-DNMT3A was able to methylate a 4.5 kb genomic region and repress HOXA5 gene expression. Reduced representation bisulfite sequencing (RRBS) and RNA-seq showed that dCas9-SunTag-DNMT3A methylated regions of interest with minimal impact on the global DNA methylome and transcriptome. Overall design: I)PCR amplicon deep sequencing of dCas9-SunTag-DNMT3A treated HEK2937 samples using Illumina Nextseq sequencing system. II) Reduced representation bisulfited sequencing (RRBS) of plasmid transfected HEK 293T cells using Illumina Hiseq2000 sequencing system. III) Whole genome bisulfite sequencing of dCas9-SunTag-DNMT3A treated HEK2937 samples. IV) RNA sequencing of dCas9-SunTag-DNMT3A treated HEK2937 samples

View SamplesTransgenic PiZ mice have been genetically engineered to express ATZ and have been a valuable experimental model for studing liver disease associated with AAT deficiency. ATZ accumulates in these mice within the ER of hepatocytes in a nearly identical manner to livers of affected patients. To investigate the pathogenesis of liver damage induced by ATZ, we performed gene expression analysis in livers of 6-week-old PiZ mice and strain-, age-, and gender-matched wild-type mouse controls. All samples were processed on Affymetrix Mouse 430A 2.0 arrays using GeneChip 3-IVT Plus and Hybridization Wash and Stain kits by means of Affymetrixs standard protocols. The analysis indicated that most genes upregulated in PiZ livers were associated with response to unfolded proteins, ER nuclear signaling pathway, and response to protein stimulus.

View SamplesMales induce dramatic physiological changes to hermaphrodites, including a significant shortening of lifespan. We have termed this effect as male-induced demise (MID) of hermaphrodites. This experiment was performed to analyse changes in gene expression due to the presence of males. We have shown that Knock down of utx-1 ameliorates the MID. In this experiment we also examine male-induce gene expression that may be altered when knocking down expression of utx-1 via RNAi.
Males shorten the life span of C. elegans hermaphrodites via secreted compounds.
