Transcriptomic study with knock-in of PIK3CD in tumoral experimental mouse model

ABSTRACT: The isoform delta of class I Phosphoinositide 3-kinase (PI3Kdelta) is expressed primarily in hematopoietic cells, and its inhibitor, idelalisib, is approved for the treatment of leukemia and lymphoma. PI3Kdelta orients the apicobasal axis and regulates lumen formation through assembly of the extracellular matrix. PI3Kdelta overexpression in hepatocellular carcinoma (HCC) cells (Huh7) leads to profound changes in cell morphogenesis and is associated to the up-regulation of stem cell markers. With tumoral experimental mouse model, investigations on PI3Kdelta implication were performed after knock-in transfection

Transcriptomic study of PIK3D transfected-Huh7 cells

Project description:The isoform delta of class I Phosphoinositide 3-kinase (PI3Kδ) is expressed primarily in hematopoietic cells, and its inhibitor, idelalisib, is approved for the treatment of leukemia and lymphoma. PI3K orients the apicobasal axis and regulates lumen formation through assembly of the extracellular matrix. PI3Kδ overexpression in hepatocellular carcinoma (HCC) cells (Huh7) leads to profound changes in cell morphogenesis and is associated to the up-regulation of stem cell markers. Transcriptomic analysis performed in triplicate on mRNA of Huh7 cells transfected with PI3Kδ construct (PI3KCD) revealed down regulation of transcripts of hepatocyte differentiation genes and up regulation of transcripts that allow prediction of ICC and mesenchymal stem cells.

Transcription profiling by array of human Glioblastoma multiforme (GBM) tumor samples to asses the intra-tumoral heterogeneity at the gene expression level

Project description:Glioblastoma multiforme (GBM) is a highly heterogeneous disease that shows an enourmous range of genetic abnormalities in comparison to other astrocytic tumors. Intra-patient heterogeneity in GBM has been poorly characterized both at phenotypic and genomic level. During surgical GBM resections, we have extracted between 4 and 8 tumor subsamples from different areas of the malignant tissue that were at least 1cm apart. Our aim to asses the intra-tumoral heterogeneity at the gene expression level to uncover important dynamics underlying GBM progression that may have relevant implication for treatment.

Human liver infected by HBV: tumoral part vs non tumoral part of the liver

Project description:Transcriptional profiling comparing tumoral and non tumoral part of human liver infected by hepatitis B virus Expression profiling of induced hepatitis B virus tumor from human liver and expression profiling of hepatitis B virus infected non tumoral part of the liver from french patients Please note that there are 62 raw files (i.e.'AFE_raw_files.tar' linked to the Series records) for 124 samples since two samples were on the same array, one in Cy3 and one in Cy5. The corresponding raw data file for each sample is indicated in the Sample description field. This dataset is part of the TransQST collection.

Human Tissues: pancreatic cancer vs. pancreatic non-tumoral tissues

Project description:Transcriptional profiling of pancreatic tumors comparing to adjacent non-tumoral pancreatic tissue by two strategies. The first strategy implies a traditional microarray assay, while the second involves a previous Suppression Subtractive Hybridization (SSH) and then the traditional microarray assay. Goal was to determine differences in gene expression profile in tumor samples by both strategies. Two-condition experiment, tumoral vs. non-tumoral tissues. Biological replicates: 6 tumoral replicates, 6 non-tumoral replicates. The same replicates for both strategies.

Transcription profiling of 57 hepato cellular carcinoma tumoral samples, 3 hepatocellular adenomas, 5 non-tumoral pools

Project description:A ""Cartes d'Identite des Tumeurs"" (CIT) project from the french Ligue Nationale Contre le Cancer (http://cit.ligue-cancer.net). 65 samples on Affymetrix HG-U133A GeneChips arrays (57 tumoral samples, 3 hepatocellular adenomas, 5 non-tumoral pools). Identification of six subgroups of Hepatocellular carcinoma (HCC) closely associated with clinical and genetic annotations (esp. risk factors and genetic alterations). Identification of a 16-gene diagnostic predictor of class membership, as well as a 5-gene signature predicting patient prognosis irrespective of HCC sub-group and which outperforms common clinical prognostic markers. Validation of both gene signatures in an independent set of 63 HCC.

Transcriptomic analysis of HCV+ vs HCV- hepatocytes and tumoral cells

Project description:HCV+ cells were detected by smiFISH on liver section of a patient with hepatocellular carcinoma. Clusters of HCV+ and HCV- cells were captured by laser microdissection and transriptomes analysed by RNA sequening. Highly sensitive single molecule fluorescent in situ hybridization applied to frozen tissue sections of a hepatitis C patient allowed the delineation of clusters of infected hepatocytes. Laser micro-dissection followed by RNAseq analysis of HCV-positive and -negative regions from the tumoral and non-tumoral tissues from the same patient revealed HCV-related deregulation of expression of genes in the tumor and in the non-tumoral tissue.

Prognostic Value of Circulating Tumoral Free DNA Versus Circulating Tumoral Cells in Patients With Colorectal Cancer Stage II-III

Project description:After curative surgical resection, detection of metastatic lymph node remains the main prognostic validated criteria on which is based the decision of adjuvant therapy. To date, none of the molecular alterations, identified as potentially predictive factor, are used in routine for therapeutic decision. The circulating markers, either in the form of free circulating DNA or in the form of circulating tumoral cells seems important potential candidates. To investigators knowledge, only one study estimated with several interesting results the prognostic interest of a coupled detection of the free circulating mutant DNA (gene KRAS) and by the hypermethylation of the p16 gene. Definitive conclusions remain however difficult to achieve because of the small number of patient included (n=58) and the fact that this study included different stages. For colorectal cancer a Chinese team presented a series of results suggesting that the presence of CTC during the postoperative course is a factor significantly related to the risk of recurrence. In multivariate analysis integrating the lymph node status and the vascular invasion, the presence of CTC appeared as an independent factor for recurrence with a hazard ratio of 29.5. The aim of the present study is to compare the prognostic value of two circulating tumoral markers KRAS point mutations and RASSF2A methylation (free tumoral DNA) and Circulating tumoral cells (CTC). The primary objective is to compare sensibility and specificity of two circulating markers (free tumoral DNA and tumoral cells) on 2 years disease free survival rate. Secondary objective is to confirm the prognostic value of circulating free tumoral DNA and circulating tumoral cells in localised colorectal cancer.
