Journal ArticleDOI
Gene expression classification of colon cancer into molecular subtypes: characterization, validation, and prognostic value
Laetitia Marisa,Aurélien de Reyniès,Alex Duval,Alex Duval,Janick Selves,Marie Pierre Gaub,Laure Vescovo,Marie-Christine Etienne-Grimaldi,Renaud Schiappa,Dominique Guenot,Mira Ayadi,Sylvain Kirzin,Maurice Chazal,Jean-François Fléjou,Jean-François Fléjou,Daniel Benchimol,Anne Berger,Arnaud Lagarde,Erwan Pencreach,F.

TL;DR: A new classification of CC into six molecular subtypes that arise through distinct biological pathways that improves the current disease stratification based on clinicopathological variables and common DNA markers is described.
Journal ArticleDOI
A refined molecular taxonomy of breast cancer
Mickaël Guedj,Laetitia Marisa,A. de Reyniès,Béatrice Orsetti,Renaud Schiappa,Frédéric Bibeau,Gaëtan MacGrogan,Florence Lerebours,Pascal Finetti,Michel Longy,Philippe Bertheau,F Bertrand,Françoise Bonnet,Anne-Laure Martin,Jean-Paul Feugeas,Ivan Bièche,Jacqueline Lehmann-Che,Rosette Lidereau,David Jérémie Birnbaum,François Bertucci,Charles Theillet,Charles Theillet +21 more
TL;DR: The data indicate that these six molecular subgroups represent well-defined clinico-biological entities of breast cancer and their identification should facilitate the detection of novel prognostic factors or therapeutical targets in breast cancer.
Journal ArticleDOI
DARPP-32 is a robust integrator of dopamine and glutamate signals.
TL;DR: The simulations showed that DARPP-32 is not only a robust signal integrator, but that its response also depends on the delay between cAMP and calcium signals affecting the response to the latter, as well as the proposed regulation of protein phosphatase-2A by calcium, which can account for the observed decrease of Threonine 75 phosphorylation upon glutamate receptor activation.
Journal ArticleDOI
Methylation profiling identifies 2 groups of gliomas according to their tumorigenesis
Julien Laffaire,Sibille Everhard,Ahmed Idbaih,Emmanuelle Crinière,Yannick Marie,Aurélien de Reyniès,Renaud Schiappa,Karima Mokhtari,Khê Hoang-Xuan,Marc Sanson,Jean-Yves Delattre,Joëlle Thillet,François Ducray +12 more
TL;DR: Using the Cancer Genome Atlas data set, it is demonstrated that GBM samples that had an LGG-like hypermethylated profile had a high rate of IDH1 mutations and a better outcome, suggesting that epigenetic alterations occur early during gliomagenesis.
Journal ArticleDOI

TL;DR: It is shown how integration of heterogeneous data in ANISEED can provide a system-level understanding of the developmental program through the automatic inference of gene regulatory interactions, the identification of inducing signals, and the discovery and explanation of novel asymmetric divisions.
