Neuron-specific changes in gene expression caused by NPC1 deficiency
  • organism-icon Mus musculus
  • sample-icon 8 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 2500

Description

Background: Niemann-Pick type C is a rare autosomal recessive lysosomal storage disorder presenting aggravating neurologic symptoms due degeneration of specific types of CNS neurons. At present, it is not well understood how neurons react to NPC1 deficiency and why some neuronal cell types are more vulnerable than others. Purpose: We took aimed to uncover how a specific type of CNS neuron that can be highly purified reacts to NPC1 deficiency based on changes in gene expression. Methods: Retinal ganglion cells were purified from individual one-week old Balb/c mice homozygous for a mutant NPC1 allele (NPC1m1N) and wildtype littermates (n = 4 mice each genotype) using immunopanning. Total RNA was isolated from acutely isolated neurons and subjected to RNAseq using 4 biological replicates for each genotype. Results: Our analysis revealed a strong downregulation of transcripts known to be decreased in mutant mice including Npc1 and Calb1 thus validating our approach. We observed a strong upregulation of genes for cellular cholesterol accretion and the downregulation of those for cholesterol release. Other changes including downregulation genes involved in the immune response and synaptic components. Conclusions: The observed changes suggest that neurons already at one week of age sense a cholesterol deficit because lipids accumulate in the endosomal-lysosomal system and cannot be redistributed intracellularly. Overall design: Gene expression analysis by RNAseq in retinal ganglion cells acutely purified from eight-days-old NPC1-deficient mice and wildtype littermates

Comparison of global gene expression between Pseudomonas aeruginosa strains 383 and 2192
  • organism-icon Pseudomonas aeruginosa
  • sample-icon 4 Downloadable Samples
  • Technology Badge Icon Affymetrix Pseudomonas aeruginosa Array (paeg1a)

Description

At mid-log phase (OD600 of 0.5), unique gene expression patterns were observed between these two strains with 3.4% of the transcripts (188/5570) expressed differentially.

RNA-Seq expression profiling of mouse DEN-initiated hepatocytes with or without Tgfbr2 inactivation
  • organism-icon Mus musculus
  • sample-icon 2 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 2000

Description

Initiated hepatocytes (IHCs), isolated from DEN exposed Tgfbr2 flox/flox mouse, were infected with GFP or Cre-expressed adenovirus, followed by 1ng/ml TGFß × 48 hours incubation. Then total RNAs were isolated and processed to routine sequencing on Illumina platform. RNA-Seq libraries were prepared from total RNA using polyA enrichment. Overall design: Examination of transcriptome differences between initiated hepatocytes with or without Tgfbr2 inactivation.

Expression profiling of ProB and PreB cells in Ebf1 heterozygous mouse bone marrow
  • organism-icon Mus musculus
  • sample-icon 8 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Genome 430 2.0 Array (mouse4302)

Description

Loss of one allele of Ebf1 impairs pre-B cell (B220+CD19+CD43low/negIgM-) expansion. In order to better understand the underlying cause of the reduced pre-B cell compartment in Ebf1+/- mice, we sorted pro-B (B220+CD19+CD43highIgM- ) as well as pre-B cells from Wt and Ebf1 heterozygote mutant mice and performed Affymetrix based microarray gene expression analysis.

Genome-wide profiling of histone H3 lysine 27 and lysine 4 trimethylation in multiple myeloma reveals the importance of Polycomb gene targeting and highlights EZH2 as a potential therapeutic target [Affymetrix]
  • organism-icon Homo sapiens
  • sample-icon 6 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Transcriptome Array 2.0 (hta20)

Description

in this study we define an epigenomic profile of PRC2 (H3K27me3 and bivalent) tragets in four newly diagnosed MM patients. Using Oncomine database we demonstarte that PRC2 targets are underexpressed with advanced ISS stages and correlated to poor outcome. Pharmacological inhibition of UNC1999 showed anti-myeloma potential in vitro by activating the expression genes related to apoptosis and cell differenatiation.
