Expression profiles in HMGN1-overexpressed neural precursor cells
  • organism-icon Mus musculus
  • sample-icon 2 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Gene 1.0 ST Array (mogene10st)

Description

Neural precursor cells (NPCs) are multipotent cells that can generate neurons, astrocytes, and oligodendrocytes in the mammalian central nervous system. Although high mobility group nucleosomal binding domain 1 (HMGN1) was highly expressed in NPCs, its functions in neural development are not fully understood. We performed microarray analysis to examine changes in gene expression between control and HMGN1-overexpressed NPCs.

Publication Title

High mobility group nucleosome-binding family proteins promote astrocyte differentiation of neural precursor cells.

Layer-specific molecular expression in neocortical astrocytes
  • organism-icon Mus musculus
  • sample-icon 6 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 2500

Description

Protoplasmic astrocytes in layers II to VI of the mammalian neocortex have historically been thought to comprise a homogeneous population. Given that layer-specific neuronal subtypes play essential roles in cortical circuitry, astrocytes might also be expected to support and modify this circuitry in a layer-specific manner. In order to investigate whether protoplasmic astrocytes exhibit layer-specific heterogeneity, we compared the gene expression profiles of astrocytes between upper layers (layers II to IV) and deep layers (layers V and VI). Although most genes known to be preferentially expressed in astrocytes (astrocyte-enriched genes) were equally expressed between upper-layer astrocytes and deep-layer astrocytes, some such genes (astrocyte-enriched genes or genes with known function in astrocytes) were significantly enriched in upper-layer astrocytes or deep-layer astrocytes. Overall design: With the use of fluorescence-activated cell sorting (FACS), we prepared upper-layer astrocytes and deep-layer astrocytes from the corresponding dissected layers of the somatosensory cortex of Aldh1l1-eGFP mice, in which all astrocytes are expected to be labeled with GFP. The meninges, layer I, and the corpus callosum were removed from upper- and deep-layer tissue samples. In addition, parts of layers IV and V were lost during separation of these layers in such a way as to prevent cross-contamination between the upper- and deep-layer samples. Total RNA from upper-layer astrocytes and deep-layer astrocytes (n = 3 brains from 4-week-old male mice) was isolated from sorted cells with TRIzol (Invitrogen) or RNAiso Plus (Takara) and was then subjected to reverse transcription with the use of a SMART-Seq v4 Ultra Low Input RNA Kit for Sequencing (Clontech). Bar-coded libraries were prepared with a Nextera XT DNA Library Preparation Kit (Illumina), and single-end 36-bp sequencing was performed with a HiSeq 2500 instrument (Illumina).

Puberty and Diabetes in the Kidney
  • organism-icon Rattus norvegicus
  • sample-icon 12 Downloadable Samples
  • Technology Badge Icon Affymetrix Rat Genome 230 2.0 Array (rat2302)

Description

Puberty unmasks or accelerates nephropathies, including the nephropathy of diabetes mellitus (DM). A number of cellular systems implicated in the kidney disease of DM interweave, forming an interdependent functional web. We performed focused microarray analysis to test the hypothesis that one or more genes in the transforming growth factor beta (TGF-) signaling system would be differentially regulated in male rats depending on the age of onset of DM.

Prepubertal onset of diabetes prevents expression of renal cortical connective tissue growth factor.

Autophagy maintains metabolism and functional activity of a subset of aged hematopoietic stem cells [gene expression]
  • organism-icon Mus musculus
  • sample-icon 6 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Gene 1.0 ST Array (mogene10st)

Description

Autophagy is critical for protecting HSCs from metabolic stress. Here, we used a genetic approach to inactivate autophagy in adult HSCs by deleting the Atg12 gene. We show that loss of autophagy causes accumulation of mitochondria and an oxidative phosphorylation (OXPHOS)-activated metabolic state, which drives accelerated myeloid differentiation likely through epigenetic deregulations rather than transcriptional changes, and impairs HSC self-renewal activity and regenerative potential.

PTH and PTHrP treatment of primary adipocytes
  • organism-icon Mus musculus
  • sample-icon 9 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Genome 430 2.0 Array (mouse4302)

Description

Parathyroid hormone (PTH) and PTH-related protein (PTHrP) are involved in cachexia associated with chronic kidney disease and cancer respectively. Tumor-derived PTHrP triggers adipose tissue browning and thereby leads to wasting of fat tissue in tumor-bearing mice. Similarly, elevated in 5/6 nephrectomized mice, PTH stimulates adipose tissue browning and wasting. Mice lacking the PTH/PTHrP receptor in their fat tissue are resistant to wasting of both adipose tissue and skeletal muscle. Therefore, the PTH/PTHrP signaling in adipocytes should activate various pathways that contribute to hypermetabolism and muscle wasting.

Multiple DNA repair pathways collectively protect against DNA damage-induced replicative aging.
  • organism-icon Caenorhabditis elegans
  • sample-icon 8 Downloadable Samples
  • Technology Badge Icon Affymetrix C. elegans Genome Array (celegans)

Description

We demonstrate that transcriptomic profiling of the NER mutant ercc-1 offers better understanding of the complex phenotypes of ercc-1 deficiency in C. elegans, as it does in mammalian models. There is a transcriptomic shift in ercc-1 mutants that suggests a stochastic impairment of growth and development, with a shift towards a higher proportion of males in the population. Extensive phenotypic analyses confirm that NER deficiency in C. elegans leads to severe developmental and growth defects and a reduced replicative lifespan, although post-mitotic lifespan is not affected. Results suggest that these defects are caused by an inability to cope with randomly occurring DNA damage, which may interfere with transcription and replication.

Publication Title

DNA damage leads to progressive replicative decline but extends the life span of long-lived mutant animals.

Di- and trimeric biological switches made of nanobody-cytokine receptor fusion proteins simulate IL-23 signaling
  • organism-icon Mus musculus
  • sample-icon 32 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Gene 1.0 ST Array (mogene10st)

Description

Cytokine-induced signal transduction is executed by natural biological switches, which among many others control immune related processes. To construct a biological device, that simulates cytokine signaling, we utilized nanobodies to generate synthetic cytokine receptors (SyCyR). High affinity GFP- and mCherry-nanobodies were selected and extracellularly fused to trans-membrane and intracellular domains of IL-23 cytokine receptors. Soluble homo- and heterodimeric GFP:mCherry fusion proteins served as SyCyR ligands. Heterodimeric GFP-mCherry and homodimeric GFP fusion proteins efficiently phenocopied IL-23 signal transduction, respectively, as demonstrated by STAT3-, ERK- and Akt-activation, SOCS3 expression and transcriptome profiling. Interestingly, the homodimeric GFP fusion protein induced IL-23 receptor homo-dimerization and activation of IL-23-like signal transduction

Publication Title

Synthetic cytokine receptors transmit biological signals using artificial ligands.
