Investigating genes regulated by mir-155 in a mouse macrophage cell line
  • organism-icon Mus musculus
  • sample-icon 2 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Genome 430 2.0 Array (mouse4302)

Description

Mammalian microRNAs (miRNAs) are emerging as key regulators of the development and function of the immune system. Here, we report a strong but transient induction of miR-155 in mouse bone marrow after injection of bacterial lipopolysaccharide (LPS) correlated with granulocyte/monocyte (GM) expansion. Demonstrating the sufficiency of miR-155 to drive GM expansion, enforced expression in mouse bone marrow cells caused GM proliferation in a manner reminiscent of LPS treatment. However, the mir-155-induced GM populations displayed pathological features characteristic of myeloid neoplasia. Extending possible relevance to human disease, miR-155 was overexpressed in the bone marrow of patients with acute myeloid leukemia (AML). Furthermore, miR-155 repressed a subset of genes implicated in hematopoietic development and disease. These data implicate miR-155 as a contributor to physiological GM expansion during inflammation and to certain pathological features associated with AML, emphasizing the importance of proper miR-155 regulation in developing myeloid cells during times of inflammatory stress.

Gonadal Identity in the Absence of pro-Testis Factor SOX9 and pro-Ovary Factor beta-catenin
  • organism-icon Mus musculus
  • sample-icon 31 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Genome 430 2.0 Array (mouse4302)

Description

The main goal of our study is to identify the molecular events that determine the gonadal identity in mammals. Although testis and ovary arise from a common embryonic primordium, they represent outcomes of opposing fate determination. This decision to differentiate into a testis or an ovary hinges upon the balance between two antagonizing factors, pro-testis SOX9 and pro-ovary -catenin.

Gonadal Identity in the Absence of Pro-Testis Factor SOX9 and Pro-Ovary Factor Beta-Catenin in Mice.

VEGF blockade enhances the antitumor effect of BRAFV600E inhibition (mouse)
  • organism-icon Mus musculus
  • sample-icon 11 Downloadable Samples
  • Technology Badge IconIllumina MouseWG-6 v2.0 expression beadchip

Description

In this work we investigated the combined effects of the BRAF inhibition and of the VEGF blockade in a preclinical model of melanoma. The purpose of this dataset was to examine the transcriptional responses of a A375 xenograft model to PLX472 and bevacizumab, either as single agents or as combination therapy. We performed species-specific analysis of gene expression to discriminate the effects of the different therapeutic regimens on tumor cells (human) and stromal microenvironment (mouse). Here, Illumina Mouse BeadChips were used to profile the transcriptome after 12 days treatment. We reported that dispensing the dual treatment is more efficient than the single compounds and the occurrence of resistance by modifying the tumor genetic programs regulating myeloid cells recruitment and extracellular matrix remodeling.

Gene expression data from RT112 following FGFR3 knock-down using FGFR3 siRNAs
  • organism-icon Homo sapiens
  • sample-icon 5 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)

Description

To better understand the molecular mechanisms underlying altered-FGFR3 oncogenic activity in bladder carcinomas, we made use of RT112 cell lines, which were derived from a human bladder tumor and endogenously expressed the FGFR3-TACC3 fusion protein, the growth and transformation of these cell lines being dependent on activated-FGFR3 activity. We conducted a gene expression analysis using Affymetrix DNA arrays in this cell line treated or not with FGFR3 siRNAs.

  • organism-icon Homo sapiens
  • sample-icon 863 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U219 Array (hgu219)

Description

Identifying the Mechanism of Action (MoA) of drugs is critical for the development of new drugs, understanding their side effects, and drug repositioning. However, identifying drug MoA has been challenging and has been traditionally attempted only though large experimental setups with little success. While advances in computational power offers the opportunity to achieve this in-silico, methods to exploit existing computational resources are still in their infancy. To overcome this, we developed a novel method to identify Drug Mechanism of Action using Network Dysregulation (DeMAND).

Expression data from third instar Drosophila eye discs
  • organism-icon Drosophila melanogaster
  • sample-icon 12 Downloadable Samples
  • Technology Badge Icon Affymetrix Drosophila Genome 2.0 Array (drosophila2)

Description

Third instar larval eye discs provide an in vivo model for cell cycle exit studies. Posterior to the Second Mitotic Wave proliferation is absent in a wild type eye disc. Inactivating mutations in tumor suppressor-like genes can lead to genome wide changes in gene expression that allow for inappropriate bypass of cell cycle exit signals posterior to the Second Mitotic Wave.

Publication Title

Cooperation between dE2F1 and Yki/Sd defines a distinct transcriptional program necessary to bypass cell cycle exit.
