Expression profiling of MCF10A cells in 2D and 3D culture
  • organism-icon Homo sapiens
  • sample-icon 13 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133A Array (hgu133a)

Description

In these microarray experiments, we characterize the gene expression of mammary epithelial cells (MCF10A cells) grown in either a traditional monolayer cell culture setting (2D) or on Matrigel, which induces single MCF10A cells to form organized acinar structures (3D). Morphogenesis of mammary epithelial cells into organized acinar structures in vitro is accompanied by widespread changes in gene expression patterns, including a substantial decrease in expression of Myc.

Dosage-dependent phenotypes in models of 16p11.2 lesions found in autism
  • organism-icon Mus musculus
  • sample-icon 37 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Gene 1.0 ST Array (mogene10st)

Description

Recurrent Copy Number Variations (CNVs) of human 16p11.2 have been associated with a variety of developmental/neurocognitive syndromes. In particular, deletion of 16p11.2 is found in patients with autism, developmental delay, and obesity. Patients with deletions or duplications have a wide range of clinical features, and siblings carrying the same deletion often have diverse symptoms. To study the consequence of 16p11.2 CNVs in a systematic manner, we used chromosome engineering to generate mice harboring deletion of the chromosomal region corresponding to 16p11.2, as well as mice harboring the reciprocal duplication. These 16p11.2 CNV models have dosage-dependent changes in gene expression, viability, brain architecture, and behavior. For each phenotype, the consequence of the deletion is more severe than that of the duplication. Of particular note is that half of the 16p11.2 deletion mice die postnatally; those that survive to adulthood are healthy and fertile, but have alterations in the hypothalamus and exhibit a behavior trap phenotypea specific behavior characteristic of rodents with lateral hypothalamic and nigrostriatal lesions. Our findings indicate that 16p11.2 CNVs cause both brain and behavioral anomalies, providing new insight into human neurodevelopmental disorders.

Gene expression profile of splenic CD19 cells from NTg, PTPROt Tg, TCL1 Tg and PTPROt/TCL1 double Tg mice
  • organism-icon Mus musculus
  • sample-icon 16 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Gene 1.0 ST Array (mogene10st)

Description

TCL1 is an an oncogene and transgenic (Tg) mice expressing TCL1 specifically in B-cells are well-characterized models for chronic lymphocytic leukemia. On the contrary, PTPROt is a phosphatase with tumor suppressor characteristics in many cancers including leukemia. Our hypothesis was that transgenic expression of PTPROt in the B-cells of TCL1 Tg mice will alleviate disease phenotype and allow the study of the in vivo mechanism of action of PTPROt. To test this we have generated Tg mice with B-cell specific expression of PTPROt and crossed these mice with the TCL1 Tg mice.

A screen to identify novel tumor suppressor genes silenced by methylation in melanoma
  • organism-icon Homo sapiens
  • sample-icon 14 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133A Array (hgu133a)

Description

Malignant melanoma is a common and frequently lethal disease. Current therapeutic interventions have little effect on survival, emphasizing the need for a better understanding of the genetic, epigenetic, and phenotypic changes in melanoma formation and progression. We identified genes that were not previously known to be silenced by methylation in melanoma using a microarray-based screen following treatment of melanoma cell lines with the DNA methylation inhibitor 5-Aza-2'-deoxycytidine.

High-throughput sequencing reveals key genes and immune homeostatic pathways activated in myeloid dendritic cells by Porphyromonas gingivalis 381 and its fimbrial mutants
  • organism-icon Homo sapiens
  • sample-icon 5 Downloadable Samples
  • Technology Badge IconIlluminaHiSeq2500

Description

Periodontitis affects 47.1% of adult population in the U.S. Porphyromonas gingivalis is an opportunistic oral pathogen that colonizes the oral mucosa, invades myeloid dendritic cells and accesses the bloodstream, brain, placenta and other organs in human with periodontitis. Periodontitis also sustains a chronic long-term pro-inflammatory immune disorder, potentially contributing to other systemic conditions such as cardiovascular disease, type 2 diabetes mellitus, adverse pregnancy outcomes, and osteoporosis. However, the role of P. gingivalis minor and major fimbriae in DC-SIGN-TLR2 crosstalk during traverses from oral mucosa to these distant sites and its influence on survival of P. gingivalis within DCs and its immune-mechanism involve at molecular/transcriptome level has not been examined. In this study to address the role of fimbriae we utilized defined bacterial mutants that solely express minor fimbriae (Mfa1+Pg), major fimbriae (FimA+Pg) or are deficient in both fimbriae (MFB) and compared with un-infected control. P. gingivalis strains were maintained anaerobically (10% H2, 10% CO2, and 80% N2) in a Forma Scientific anaerobic system glove box model 1025/1029 at 37°C in Difco anaerobe broth MIC. Mutant strains were maintained using erythromycin (5 µg/ml) for mutant Mfa1+Pg, tetracycline (2 µg/ml) for mutant FimA+Pg and both erythromycin and tetracycline for double fimbriae mutant MFB. Bacterial suspensions were washed five times in PBS and re-suspended for spectrophotometer reading at OD 660 nm of 0.11, which previously determined to be equal to 5 x 107 CFU. For bacterial CFSE staining, the suspension were washed (3 times) and re-suspended in 5 µM of CFSE in PBS. The bacteria were incubated for 30 min at 37°C in the dark. MoDCs were pulsed with Pg381, Mfa1+Pg, FimA+Pg and MFB at 10 MOI and incubated with the MoDCs for 12 hours and each experimental condition was performed in triplicate. Overall design: To facilitate our understanding on host immunity and defense mechanism of this pathogen, here we used the Illumina High-throughput RNA-seq transcriptome profiling to investigate the myeloid dendritic cells response to oral Amphibiont (1. Pg381, 2. Mfa1+Pg, 3. FimA+Pg, 4. MFB and 5. Un-infected control group).

Quantitative Transcriptome Analysis of the Stomach Neck Mucosa from Control vs Claudin (CLDN)-18 knockout mice.
  • organism-icon Mus musculus
  • sample-icon 6 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 2000

Description

Purpose: To determine early changes in gene expression that drive gastric cancer development in the landscape of CLDN18 loss using RNAseq. Results: Although claudin-18 is a tight junction protein and should regulate paracellular permeabiity and/or ion flux across the mucosa, we showed this protein is rather a potent tumor suppressor that regulates cellular signaling and differentiation pathways in gastric epithelial cells. Methods: Stomach neck region mRNA profiles of 7-day-old wild-type (WT) and claudin-18 knockout (CLDN18-/-) mice were generated by deep sequencing, in triplicate, using the Illumina HiSeq2000 sequencing system. The resulting sequences were mapped to the Mouse genome (mm10) using STAR aliger and P-values were adjusted using the Benjamini-Hochberg procedure (J R Statist Soc B 1995;57:289-300). Conclusions: Loss of claudin-18 promotes gastric cancer development by modulating the expression program of gastric epithelial cells, including cellular signaling and differentiation pathways that are required for mucosal homeostasis. Overall design: Stomach (neck region only) mRNA profiles of 7-day old wild-type (WT) and CLDN18-/- mice were generated by deep sequencing, in triplicate, using an Illumina HiSeq2000 sequencing system.
