Prox1 determines hepatocyte versus cholangiocyte cell fate in liver progenitors
  • organism-icon Mus musculus
  • sample-icon 2 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Genome 430 2.0 Array (mouse4302)

Description

The mammalian liver, the largest solid organ in the body, accomplishes multiple critical roles necessary to preserve homeostasis. Human liver diseases are debilitating, costly and very often result in death. Uncovering developmental mechanisms that establish the complex architecture of the liver or generate the cellular diversity of this organ is necessary to develop more adequate methods to prevent, diagnose and cure liver diseases. This study investigated the role of the homeobox gene Prox1 during mouse hepatogenesis.

Publication Title

Prox1 ablation in hepatic progenitors causes defective hepatocyte specification and increases biliary cell commitment.

G9a-Mediated Methylation of ERa Links the PHF20/MOF Histone Acetyltransferase Complex to Hormonal Gene Expression
  • organism-icon Homo sapiens
  • sample-icon 12 Downloadable Samples
  • Technology Badge IconIlluminaHiSeq2000

Description

The euchromatin histone methyltransferase 2 (EHMT2, aka G9a) methylates histone H3K9 to repress gene expression, but it also acts as a coactivator for some nuclear receptors. The molecular mechanisms underlying this activation remain elusive. Here we show that G9a functions as a bona fide coactivator of the endogenous estrogen receptor a (ERa) in breast cancer cells in a histone methylation-independent manner. G9a dimethylates ERa protein at lysine 235 both in vitro and in cells. Dimethylation of ERaK235 (ERaK235me2) is recognized by the Tudor domain of PHF20, which in turn recruits the MOF histone acetyltransferase (HAT) complex to ERa target gene promoters to deposit histone H4K16 acetylation promoting active transcription. Together, our in vitro and in vivo data establish the molecular mechanism by which G9a functions as an ERa coactivator. Along with the PHF20/MOF complex, G9a links the crosstalk between ERa methylation and histone acetylation governing the epigenetic regulation of hormonal gene expression. Overall design: G9a KD RNA-seq and PHF20 KD RNA-seq with and without E2 treatment

Evolving Spindlin1 Small Molecule Inhibitors Using Protein Microarrays
  • organism-icon Homo sapiens
  • sample-icon 9 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 2500

Description

Using a library of tagged UNC1215 analogs, we screened a protein domain microarray of methyl-lysine effector molecules to rapidly detect compounds with novel binding profiles. Using this approach, we identified a compound (EML405) that acquired a novel interaction with the Tudor domain-containing protein Spindlin1 (SPIN1). Structural studies revealed that the symmetric nature of EML405 allows it to simultaneously engage two of SPIN1's Tudor domains, and also facilitated the rational synthesis of more selective SPIN1 inhibitor (EML631). The EML631 compound engages SPIN1 in cells, blocks its ability to “read” H3K4me3 marks, and inhibits its transcriptional coactivator activity. Overall design: RNA-seq of control, SPIN1 siRNA knockdown (24 hour post-transfection) and EML631 treated (10 mM, 3 days) T778 cells

Genetic deletion or small molecule inhibition of the arginine methyltransferase PRMT5 exhibit anti-tumoral activity in mouse models of MLL-rearranged AML
  • organism-icon Mus musculus
  • sample-icon 6 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 2000

Description

The hematological malignancies classified as Mixed Lineage leukemias (MLL) harbor fusions of the MLL1 gene to partners that are members of transcriptional elongation complexes. MLL-rearranged leukemias are associated with extremely poor prognosis and response to conventional therapies and efforts to identify molecular targets are urgently needed. Using mouse models of MLL-rearranged acute myeloid leukemia (AML), here we show that genetic inactivation or small molecule inhibition of the protein arginine methyltransferase PRMT5 exhibit anti-tumoral activity in MLL-fusion protein driven transformation. Genome wide transcriptional analysis revealed that inhibition of PRMT5 methyltransferase activity overrides the differentiation block in leukemia cells without affecting the expression of MLL-fusion direct oncogenic targets. Furthermore, we find that this differentiation block is mediated by transcriptional silencing of the cyclin-dependent kinase inhibitor p21 (CDKN1a) gene in leukemia cells. Our study provides pre-clinical rationale for targeting PRMT5 using small molecule inhibitors in the treatment of leukemias harboring MLL-rearrangements. Overall design: RNA-seq data from 72h-treated DMSO and EPZ 015666 (PRMT5i) MLL-ENL/NrasG12D leukemia cells, three independent replicates.

The impact of transgenic Uchl1 on gene expression in germinal center B-cells from ImHABCL6 mice
  • organism-icon Mus musculus
  • sample-icon 6 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Genome 430 2.0 Array (mouse4302)

Description

This study seeks to understand the mechanisms behind enhanced lymphomagenesis observed in ImHABCL6/Uchl1 mice compared with ImHABCL6 alone. As the lymphomas arise from germinal center (GC) B-cells, we reasoned that transgenic Uchl1 altered the gene expression patterns in GC B-cells from these animals. We therefore isolated pre-malignant GC B-cells and examined the gene expression patterns to identify pathways affected by the addition of Uchl1.

Expression data from rat tendon fibroblasts treated with PRP and PPP.
  • organism-icon Rattus norvegicus
  • sample-icon 4 Downloadable Samples
  • Technology Badge Icon Affymetrix Rat Gene 2.1 ST Array (ragene21st)

Description

Tendon is a hypocellular tissue that contains functional cable-like units of type I collagen responsible for the transmission of force from muscle to bone. In the setting of injury or disease, patients can develop chronic tendinopathies that are characterized by pain, loss of function and persistent inflammatory changes that are often difficult to treat. Platelet-rich plasma (PRP) has shown promise in the treatment of chronic tendinopathy, but little is known about the mechanisms by which PRP can improve tendon healing. PRP contains many different growth factors and cytokines, and since these proteins can both activate and inhibit various signaling pathways it has been challenging to determine precisely which signaling pathways and cellular responses are most important. Using state-of-the-art bioinformatics tools and genome wide-expression profiling, the purpose of this study was to determine the signaling pathways activated within cultured tendon fibroblasts in response to PRP treatment.
