Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Background: Preterm birth is the leading cause of all infant mortality. In 2004, 12.5% of all births were preterm. In order to understand preterm labor, we must first understand normal labor. Since many of the myometrial changes that occur during pregnancy are similar in mice and humans and mouse gestation is short, we have studied the uterine genes that change in the mouse during pregnancy. Here, we used microarray analysis to identify uterine genes in the gravid mouse that are differentially regulated in the cyclooxygenase-1 knockout mouse model of delayed parturition.
Publication Title
Identification of 9 uterine genes that are regulated during mouse pregnancy and exhibit abnormal levels in the cyclooxygenase-1 knockout mouse.

Description
The rhesus embryonic stem cell line 366.4 differentiates into serotonin neurons. RNA was extracted from ESC colonies, embryoid body (Ebs), Neurospheres in selection (N1), Proliferating serotonin neurons (N2) and differentiating serotonin neurons (N3). RNA was labeled with Enzo biotin labelling kit and hybridized to Rhesus chip from Affymetrix.

Description
Glomerular podocyte cells are critical for the function of the renal ultrafiltration barrier. The highly specialized cell-cell junction of podocytes, the slit diaphragm, has a central role in the filtration barrier. Dendrin is a poorly characterized cytosolic component of the slit diaphragm in where it interacts with nephrin and Cd2ap. In this study, we have generated a dendrin knockout mouse line and explored the molecular interactions of dendrin. Dendrin-deficient mice were viable, fertile and had normal life span.
Publication Title
Wtip- and gadd45a-interacting protein dendrin is not crucial for the development or maintenance of the glomerular filtration barrier.

Illumina HiSeq 2500
Description
We observed that mutations in CBP60a, CML46, CML47 and WRKY70 enhanced plant resistance to Pma likely through different mechanisms. To investigate their contributions to enhanced resistance at the transcriptome level, we designed this experiment to measure their response to Pma using the SMART-3Seq method. Overall design: Mature leaves of Arabidopsis plants of seven different genotypes were infiltrated with mock or Pma. Samples were collected 24 hours after treatment. Each experiment contains one sample consisted of two leaves for each genotype-treatment combination. In total three independent experiments were conducted.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
A major part of plant immune response is mediated by signaling pathways controlled by three hormnes, jasmonate, ethylene, and salicylate. The involvement of each of these hormone signaling pathways in Arabidopsis thaliana was investigated in response to infection of a necrotrophic fungal pathogen, A. brassicicola. Arabideopsis mutants deficient in these hormone signaling pathways were compared to wild type.

Description
Despite their importance, plant MAP kinase targets are still poorly elucidated. Here, the specific in vivo interaction of an ethylene response factor (ERF104) with the Arabidopsis MAP kinase, MPK6, is shown by fluorescence resonance energy transfer. The interaction, which is lost within minutes after treatment with the flagellin-derived flg22 peptide, is dependent on both MPK6 kinase activity and rapid ethylene signaling initiated downstream of MPK6 activation. ERF104 is an MPK6 substrate and phosphorylation site mutations affected its stability. ERF104 activates promoters with GCC elements. This was evident from microarray data of overexpressing transgenic plants, where promoters of up regulated genes contain GCC motifs and chromatin immunoprecipitation showing ERF104 association with PDF1.2 promoter. The ERF104 overexpressor did not affect biotrophic bacteria proliferation but was more susceptible to necrotrophic Botrytis cinerea. Microarray performed with erf104 or mpk6 revealed only a limited number of flg22-induced genes that require these elements - possibly as a

Description
Platelet-derived growth factor-C (PDGF-C) is one of three known ligands for the tyrosine kinase receptor PDGFR. Analysis of Pdgfc null mice has demonstrated roles for PDGF-C in palate closure and the formation of cerebral ventricles, but redundancy with other PDGFR ligands might hide additional functions. In search of further developmental roles for PDGF-C, we generated mice that were double mutants for Pdgfc -/- and Pdgfra GFP/+. These mice display a range of severe phenotypes including cerebellar malformation, neuronal over-migration in the cerebral cortex, spina bifida and lung emphysema. We focused our analysis on the central nervous system (CNS), where PDGF-C was identified as a critical factor for the formation of meninges and assembly of the glia limitans basement membrane.
