Journal ArticleDOI
Prognosis and histopathologic features in papillary tumors of the pineal region: a retrospective multicenter study of 31 cases.
Michelle Fèvre-Montange,Michelle Fèvre-Montange,Martin Hasselblatt,Dominique Figarella-Branger,Laurent Chauveinc,Jacques Champier,Jacques Champier,Ghislaine Saint-Pierre,Luc Taillandier,Alix Coulon,Werner Paulus,François Fauchon,Anne Jouvet,Anne Jouvet +13 more
TL;DR: The clinical course of PTPR is characterized by frequent local recurrence, and the value of radiotherapy on disease progression will need to be investigated in future prospective trials.
Journal ArticleDOI
Microarray analysis reveals differential gene expression patterns in tumors of the pineal region.
Michelle Fèvre-Montange,Jacques Champier,Alexandru Szathmari,Anne Wierinckx,Carmine Mottolese,Jacques Guyotat,Dominique Figarella-Branger,Anne Jouvet,Joël Lachuer +8 more
TL;DR: Using reverse transcriptase-polymerase chain reaction on 13 PPTs, it is demonstrated that PRAME, CD24, POU4F2, and HOXD13 might be candidates for grading PPT with intermediate differentiation.
Journal ArticleDOI
Evidence for tryptophan hydroxylase and hydroxy-indol-O-methyl-transferase mRNAs in human blood platelets.
Jacques Champier,Bruno Claustrat,Roger Besançon,Cécile Eymin,Charlotte Killer,Anne Jouvet,Geneviéve Chamba,Michelle Fèvre-Montange +7 more
TL;DR: Results show TPOH and HIOMT mRNAs to be present in human blood and support the hypothesis that serotonin and melatonin may be synthesized in blood and, more particularly, in platelets.
Journal ArticleDOI
Folate depletion changes gene expression of fatty acid metabolism, DNA synthesis, and circadian cycle in male mice.
TL;DR: It is shown that, in the mouse liver, dietary folate depletion leads to major changes in expression of several genes involved in fatty acid metabolism, DNA synthesis, and expression of circadian genes.
Journal ArticleDOI
Microarray gene expression profiling in meningiomas: Differential expression according to grade or histopathological subtype
Michelle Fèvre-Montange,Jacques Champier,Anne Durand,Anne Wierinckx,Jérôme Honnorat,Jacques Guyotat,Anne Jouvet +6 more
TL;DR: Results might make it possible to determine which benign meningiomas might recur despite complete resection, and will provide helpful information for neurosurgeons in the follow-up of the patients.
