Human Herpesvirus-8 infection of pulmonary microvascular entdothelial cells
  • organism-icon Homo sapiens
  • sample-icon 5 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)

Description

Human herpesvirus-8 (HHV-8) is the causative agent of Kaposis sarcoma and is associated with the angioproliferative disorders primary effusion lymphoma (PEL) and multicentric Castlemans disease (MCD). We have previously described evidence of HHV-8 infection within the pulmonary vasculature of patients with idiopathic pulmonary arterial hypertension (IPAH). We speculated that viral infection of the pulmonary microvascular endothelial cells could cause the angioproliferative phenotype characteristic of severe pulmonary arterial hypertension (PAH). We now demonstrate the ability of HHV-8 to infect human pulmonary microvascular endothelial cells (HPMVECs) in vitro, confirming both latent and lytic infection. HHV-8 infection of HPMVECs resulted in significant changes of gene expression including alterations of pathways integral to both cellular apoptosis and angiogenesis. This infection also results in alterations of genes integral to the bone morphogenic protein (BMP) pathway, including down regulation of bone morphogenic protein receptor 1a (BMPR1a) and bone morphogenic protein 4 (BMP4). Other genes previously implicated in the development of PAH are also altered in expression by HHV-8 infection. These include increased expression of Interleukin-6 (IL-6) and the matrix metalloproteinases (MMP)-1, MMP-2 and MMP-10. Lastly, cells infected with HHV-8 apoptosis resistant. Infection of pulmonary microvascular endothelial cells with human herepesvirus-8 results in alteration of the BMP pathway as well as an anti-apoptotic phenotype, consistent with the development of plexiform lesions characteristic of pulmonary arterial hypertension.

Description

Boron is essential for plants, and boron availability in soil is an important determinant of agricultural production. Boron availability in soil is limited at many regions in the world, including Japan. Under boron deficient conditions, leaf expansion and root elongation, apical dominance, flower development,and fruit and seed sets are inhibited.

Avidity Selection of Natural Killer Response to MCMV
  • organism-icon Mus musculus
  • sample-icon 8 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 4000

Description

Natural killer (NK) cells are innate lymphocytes that possess features of adaptive immunity, such as the ability to recognize specific antigen, among others. In MCMV infection, the engagement of a subset of NK cells expressing an activating receptor Ly49H with MCMV-derived glycoprotein m157 results in a clonal-like expansion and the generation of a small pool of long-lived memory cells with higher Ly49H expression than the naive Ly49H-expressing NK cell pool. In this study, we interrogate the transcriptional differences between NK cells that express high verus low levels of Ly49H early after infection. Overall design: RNASeq was performed on Ly49Hhi and Ly49Hlow NK cells harvested after 1.5 days post in vivo infection; 4 replicates per group and 50,000 cells per replicate.

Increased lactate secretion by cancer cells sustains non-cell-autonomous adaptive resistance to MET and EGFR targeted therapies.
  • organism-icon Mus musculus
  • sample-icon 4 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 2000

Description

Microenvironment is known to influence cancer drug response and sustain resistance to therapies targeting receptor-tyrosine kinases. However if and how tumor microenvironment can be altered during treatment, contributing to resistance onset is not known. Here we show that, under prolonged treatment with tyrosine kinase inhibitors (TKIs), EGFR- or MET-addicted cancer cells displayed a metabolic shift towards increased glycolysis and lactate production. We identified secreted lactate as the key molecule able to instruct Cancer Associated Fibroblasts (CAFs) to produce Hepatocyte Growth Factor (HGF) in a NF-KB dependent manner. Increased HGF, activating MET-dependent signaling in cancer cells, sustained resistance to TKIs. Functional targeting or pharmacological inhibition of lactate dehydrogenase prevented and overcame in vivo resistance, demonstrating the crucial role of this metabolite in the adaptive process. This non-cell-autonomous, adaptive resistance mechanism was observed in NSCLC patients progressed on EGFR TKIs, demonstrating the clinical relevance of our findings and opening novel scenarios in the challenge to drug resistance Overall design: RNA-seq analysis of 2 different samples, each one with 2 biological replicates (4 sequencing runs in total).

Expression data from brain tissue of Rattus norvegicus treated with D-Serine
  • organism-icon Rattus norvegicus
  • sample-icon 24 Downloadable Samples
  • Technology Badge Icon Affymetrix Rat Genome 230 2.0 Array (rat2302)

Description

d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxicity) in brain tissue. The transcriptomic changes that occur in the brain after d-serine exposure have not been fully explored.

Publication Title

D-Serine exposure resulted in gene expression changes implicated in neurodegenerative disorders and neuronal dysfunction in male Fischer 344 rats.

WT and Get1 +/- Bladder Time Course
  • organism-icon Mus musculus
  • sample-icon 8 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Genome 430 2.0 Array (mouse4302)

Description

Skin and bladder epithelia form effective permeability barriers through the activation of distinct differentiation gene programs. Employing a genome-wide gene expression study, we identified transcription regulators whose expression correlates highly with that of differentiation markers both in bladder and skin, including the Grainyhead factor Get1/Grhl3, already known to be important for epidermal barrier formation. In the bladder, Get1 is most highly expressed in the differentiated umbrella cells and its mutation in mice leads to a defective bladder epithelial barrier formation due to failure of apical membrane specialization. Genes encoding components of the specialized urothelial membrane, the uroplakins, were downregulated in Get1-/- mice. At least one of these genes, Uroplakin II, is a direct target of Get1. The urothelial-specific activation of the Uroplakin II gene is due to selective binding of Get1 to the Uroplakin II promoter in urothelial cells, most likely regulated by histone modifications. These results demonstrate a key role for Get1 in urothelial differentiation and barrier formation.

The epidermal differentiation-associated Grainyhead gene Get1/Grhl3 also regulates urothelial differentiation.

Expression data for nave IL-2 and IL-12 primed Pmel-1 CD8+ T-cells
  • organism-icon Mus musculus
  • sample-icon 6 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Gene 1.0 ST Array (mogene10st)

Description

The expansion, trafficking and functional effectiveness of adoptively transferred CD8+ T-cells play a critical role in mediating effective anti-tumor immunity. However, the mechanisms which program the highly proliferative and functional state of CD8+ T-cells are not completely understood. We hypothesized that IL-12, a cytokine commonly induced by TLR activation, could enhance T-cell priming by altering responsiveness to antigen and cytokines. Priming of tumor specific CD8+ T-cells in the presence of IL-12 induced the acquisition of a 'polyfunctional' effector response and increased the generation of memory cells. Moreover, IL-12 priming also promoted high levels of the IL-2 receptor alpha-chain (CD25) and robust IL-2 mediated activation of STAT5. This sensitivity to IL-2 translated into enhanced in vivo proliferation of adoptively transferred CD8+ T-cells. Furthermore, real-time, in vivo imaging of T-cell trafficking confirmed the ability of IL-12 priming to drive in vivo proliferation. IL-12 priming enhanced the anti-tumor function of adoptively transferred cells by reducing established subcutaneous tumor burden, and significantly increasing survival in an established intracranial tumor model. Finally, IL-12 priming of human PBMCs generates tumor specific T-cells phenotypically and functionally similar to IL-12 primed Pmel-1 T-cells. These results highlight IL-12 as an important mediator of CD8+ T-cell effector function and anti-tumor immunity.
