Construire un programme de recherche technologique sur la formation des enseignants : choix épistémologiques et théoriques

open access: yes, 2015
L’objectif de cet article est de contribuer a definir ce que pourrait etre un programme de recherche technologique (PRT) dans le cadre de la formation des enseignants a partir d’une theorie de l’action collective.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Consistent estimation of the filtering and marginal smoothing distributions in nonparametric hidden Markov models [PDF]

open access: yes, 2015
In this paper, we consider the filtering and smoothing recursions in nonparametric finite state space hidden Markov models (HMMs) when the parameters of the model are unknown and replaced by estimators.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Interrogating the immune landscape of microsatellite stable RAS‐mutated colon cancer

open access: yesMolecular Oncology, EarlyView.
COLOSSUS project RAS‐mutated MSS colon cancer study explored transcriptomics and immune cell density by immunohistochemistry (IHC), Immunoscore (IS), ISIC/TuLIS scores, mutation counts, and detected different prevalences but similar microenvironment composition across immune markers with clinical relevance for future immunotherapy combination ...

L'EEES i la identitat europea: interpretació de les principals autoritats The EHEA and European identity: the main authorities' interpretation El EEES y la identidad europea: interpretación de les principales autoridades

open access: yesTemps d'Educació, 2013
El procés de construcció de l'Espai Europeu d'Educació Superior (EEES) no ha estat exempt de controvèrsia i diferents nivells d'interpretació en la seva creació, fonamentació i desenvolupament.

Gestion agronomique des parcelles et des systèmes de culture : un élément clé pour la production durable des cultures oléagineuses et pour l’orientation des programmes de recherche/développement

open access: yesOilseeds and fats, crops and lipids, 2015
À partir des études en cours au CETIOM ou chez les partenaires de R&D du CETIOM, le cahier des charges pour la production d’oléagineux dans des systèmes de culture durables est analysé.

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

open access: yesMolecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.
