View SamplesThe link between upper and lower airways in patients with both asthma and allergic rhinitis is still poorly understood. As the biological complexity of these disorders can be captured by gene expression profiling we hypothesized that the clinical expression of rhinitis and/or asthma is related to differential gene expression between upper and lower airways epithelium.

View SamplesWe compared the transcriptomes of EpiSCs maintained in the presence or absence of Wnt pathway inhibitor IWP2. We screened also our gene expression data for potential markers for genuine EpiSCs, maintained in the presence of Wnt inhibition and compared with ESC expression data. We compared the transcriptomes of EpiSCs maintained in the presence or absence of IWP2. The high level of Wnt-induced differentiation occurring in conventional EpiSC cultures may have interfered with the analysis of their characteristics. By applying Wnt inhibitors we are now able to establish the properties of genuine EpiSCs.
Endogenous WNT signals mediate BMP-induced and spontaneous differentiation of epiblast stem cells and human embryonic stem cells.

View SamplesWe used RNA-Seq to analyse the interactions between Bmp4 and Wnt at a genome-wide level in EpiSCs treated for 48 hrs with Bmp4 and/or Wnt3a in the presence of Activin and bFGF. Overall design: Control EpiSC were cultured in the presence of IWP2 for 48h. Cells were cultured with BMP4 with or without IWP2; Wnt3a and Wnt3a with BMP4 for 48h.

View SamplesMice wild type or knocked-out for the MyD88 gene specifically in liver, were recruited for this expression profiling experiment. Each group of mice (WT versus LKO) were fed with a control diet or a high fat diet. Then mice were sacrificed and liver samples form were processed for RNA extraction. Total liver RNA of each sample was then pooled with those of the same group and treatment for microarray hybridization.

View SamplesMice knocked-out or wild type for the NAPE PLD gene specifically in adipose tissue, were recruited for this expression profiling experiment. Each group of mice (WT versus cKO) were fed with a control diet or a high fat diet. Then mice were sacrificed and adipose tissue samples form the subcutaneous adipose tissue were processed for RNA extraction. Total RNA of each sample was then pooled with those of the same group and treatment for microarray hybridization.
Adipose tissue NAPE-PLD controls fat mass development by altering the browning process and gut microbiota.

View SamplesRheumatoid arthritis (RA) is a chronic, inflammatory joint disease of unknown etiology and pronounced inter-patient heterogeneity. To characterize RA at the molecular level and to uncover key pathomechanisms, we performed whole-genome gene expression analyses. Synovial tissues from rheumatoid arthritis patients were compared to those from osteoarthritis patients and to normal donors.

View SamplesAccumulating data indicate translation plays a role in cancer biology, particularly its rate limiting stage of initiation. Despite this evolving recognition, the function and importance of specific translation initiation factors is unresolved. The eukaryotic translation initiation complex eIF4F consists of eIF4E and eIF4G at a 1:1 ratio. Although it is expected that they display interdependent functions, several publications suggest independent mechanisms. This study is the first to directly assess the relative contribution of eIF4F components to the expressed cellular proteome, transcription factors, microRNAs, and phenotype in a malignancy known for extensive protein synthesis- multiple myeloma (MM). Previously, we have shown that eIF4E/eIF4GI attenuation (siRNA/ Avastin) deleteriously affected MM cells' fate and reduced levels of eIF4E/eIF4GI established targets. Here, we demonstrated that eIF4E/eIF4GI indeed have individual influences on cell proteome. We used an objective, high throughput assay of mRNA microarrays to examine the significance of eIF4E/eIF4GI silencing to several cellular facets such as transcription factors, microRNAs and phenotype. We showed different imprints for eIF4E and eIF4GI in all assayed aspects. These results promote our understanding of the relative contribution and importance of eIF4E and eIF4GI to the malignant phenotype and shed light on their function in eIF4F translation initiation complex.
eIF4E and eIF4GI have distinct and differential imprints on multiple myeloma's proteome and signaling.
