CD69 is a transmembrane protein expressed on the surface of activated leukocyte. The ligand for CD69 and the intracellular signaling pathway of this molecule are yet unknown. It is widely used as a marker of activated lymphocyte, but its function in immune system is not known.
CD69 regulates type I IFN-induced tolerogenic signals to mucosal CD4 T cells that attenuate their colitogenic potential.

View SamplesThe tumor microenvironment strongly influences cancer development, progression and metastasis. The role of carcinoma-associated fibroblasts (CAFs) in these processes and their clinical impact has not been studied systematically in non-small cell lung carcinoma (NSCLC). We established primary cultures of CAFs and matched normal fibroblasts (NFs) from 15 resected NSCLC. We demonstrate that CAFs have greater ability than NFs to enhance the tumorigenicity of lung cancer cell lines. Microarray gene expression analysis of the 15 matched CAF and NF cell lines identified 46 differentially expressed genes, encoding for proteins that are significantly enriched for extracellular proteins regulated by the TGF-beta signaling pathway. We have identified a subset of 11 genes that formed a prognostic gene expression signature, which was validated in multiple independent NSCLC microarray datasets. Functional annotation using protein-protein interaction analyses of these and published cancer stroma-associated gene expression changes revealed prominent involvement of the focal adhesion and MAPK signalling pathways. Fourteen (30%) of the 46 genes also were differentially expressed in laser-capture micro-dissected corresponding primary tumor stroma compared to the matched normal lung. Six of these 14 genes could be induced by TGF-beta1 in NF. The results establish the prognostic impact of CAF-associated gene expression changes in NSCLC patients.

View SamplesTo describe normal cardiac and brain development during late first and early second trimester in human fetuses using microarray and pathways analysis and the creation of a corresponding normal database. RNA from recovered tissues was used for transcriptome analysis with Affymetrix 1.0 ST microarray chip. From the amassed data we investigated differences in cardiac and brain development within the 10-18 GA period dividing the sample by GA in three groups: 10-12 (H1), 13-15(H2) and 16-18(H3) weeks. A fold change of 2 or above adjusted for a false discovery rate of 5% was used as initial cut-off to determine differential gene expression for individual genes. Test for enrichment to identify functional groups were carried out using the Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG). Array analysis correctly identified the cardiac specific genes, and transcripts reported to be differentially expressed were confirmed by qRT-PCR.

View SamplesUterine receptivity implies a dialogue between the hormonally primed maternal endometrium and the free-floating blastocyst. Endometrial stromal cells proliferate, avert apoptosis, and undergo decidualization in preparation for implantation; however, the molecular mechanisms that underlie differentiation into the decidual phenotype remain largely undefined. The Notch family of transmembrane receptors transduce extracellular signals responsible for cell survival, cell-to-cell communication, and trans-differentiation, all fundamental processes for decidualization and pregnancy. Using a murine artificial decidualization model, pharmacological inhibition of Notch signaling by gamma-secretase inhibition resulted in significantly decreased deciduoma. Furthermore, a progesterone receptor (PR)-Cre Notch1 bigenic (Notch1d/d) confirmed a Notch1-dependant hypomorphic decidual phenotype.
Notch1 mediates uterine stromal differentiation and is critical for complete decidualization in the mouse.

View SamplesPancreas organogenesis is a highly dynamic process where neighbouring tissue interactions lead to dynamic changes in gene regulatory networks that orchestrates endocrine, exocrine and ductal lineage formation. To understand the spatio-temporal regulatory logic we have used the Forkhead transcription factor Foxa2-Venus fusion (FVF) knock-in reporter mouse to separate the FVF+ pancreatic epithelium from the FVF- surrounding mesenchyme and blood vessels to perform a whole genome-wide mRNA expression profiling at embryonic day (E)12.5-15.5. This allowed us to annotate genes and molecular processes differentially regulated in these cell types and compartments of the pancreas to generate a dynamic transcriptional landscape.
