<h4>Background</h4>The molecular characteristics associated with the response to treatment in glioblastomas (GBMs) remain largely unknown. We performed a retrospective study to assess the genomic characteristics associated with the response of GBMs to either first-line chemotherapy or radiation therapy. The gene expression (n = 56) and genomic profiles (n = 67) of responders and non-responders to first-line chemotherapy or radiation therapy alone were compared on Affymetrix Plus 2 gene expressio ...[more]

Gene expression Classification of Colon Cancer defines six molecular subtypes with distinct clinical, molecular and survival characteristics [CGH]

Project description:From a clinical and molecular perspective, colon cancer (CC) is a heterogeneous disease but to date no classification based on high-density transcriptome data has been established. The aim of this study was to build up a robust molecular classification ofÂ mRNA expression profiles (Affymetrix U133Plus2) ofÂ a large series of 443 CC and to validate it on an independent serie of 123 CC and 906 public dataset.Â We identified and validated six molecular subtypes in this large cohort as a combination of multiple molecular processes that complement current disease stratification based on clinicopathological variables and molecular markers. The biological relevance of these subtypes was consolidated by significant differences in survival. These insights open new perspectives for improving prognostic models and targeted therapies. Among a large series of colon cancers collected for the Cartes d'IdentitÃ© des Tumeurs (CIT) program from the French Ligue Nationale Contre le Cancer (http://cit.ligue-cancer.net), 566 were analyzed for mRNA expression profiles using Affymetrix U133plus2 chip and, among theses, 463 could also be analyzed for DNA alteration profiles using the CGH Array (Â CIT-CGHarray V6). The 566 tumors was divided into a discovery dataset of 443 CC and a validation dataset of 123 CC.

Transcription profiling of human ductal and lobular breast cancers with familial or Cowden disease history.

Project description:A Cartes d'Identite des Tumeurs (CIT) project from the french Ligue Nationale Contre le Cancer (http://cit.ligue-cancer.net) | 74 samples on Affymetrix HG-U133 Plus 2.0 GeneChips arrays for 74 patients. 5 samples on CGH CIT v7 | Breast carcinoma is the main malignant tumor occurring in patients with Cowden disease, a cancer prone syndrome caused by germline mutation of the tumor suppressor gene PTEN. To better understand this disease, we have performed a transcriptomic study of three Cowden disease breast carcinomas included in a panel of 74 familial breast cancers. Unsupervised clustering of these 74 tumors followed the intrinsic gene classification of breast cancer except for a group of five tumors that included the three Cowden tumors. The gene expression profile of the Cowden tumors shows considerable overlap with that of a breast cancer subgroup known as molecular apocrine breast carcinoma, which is suspected to have increased androgenic signaling and shows frequent ERBB2 amplification. A histological and immunohistochemical study performed on 13 additional cases of Cowden disease breast carcinomas, for which RNA was not available, showed that they have apocrine histological features and express GGT1, a marker of molecular apocrine breast carcinoma. These data suggest that activation of the ERBB2-PI3K-AKT pathway by loss of PTEN at early stages of tumorigenesis promotes the formation of breast tumors with apocrine features. | Submitter : Renaud Schiappa schiappar@ligue-cancer.net | Project leader : Michel Longy longy@bergonie.org
