Temps et Oralité dans le Conte Oral

This article addresses the question of narrative tense usage in a particular variety of performed oral narration in modern French, i.e. oral storytelling. We examine the narrative tense systems used in both traditional and new storytelling, comparing these with well-attested oral and written patterns and with theoretical models such as Benveniste's, Weinrich's and Revaz's. We examine briefly some of the key functions of the tense alternations attested, again comparing these to patterns in other types of discourse, and conclude by considering the nature of the « orality » in question.

ADAM17-Dependent c-MET-STAT3 Signaling Mediates Resistance to MEK Inhibitors in <i>KRASi> Mutant Colorectal Cancer

There are currently no approved targeted therapies for advanced KRAS mutant (KRASMT) colorectal cancer (CRC). Using a unique systems biology approach, we identified JAK1/2-dependent activation of STAT3 as the key mediator of resistance to MEK inhibitors in KRASMT CRC in vitro and in vivo. Further analyses identified acute increases in c-MET activity following treatment with MEK inhibitors in KRASMT CRC models, which was demonstrated to promote JAK1/2-STAT3-mediated resistance. Furthermore, activation of c-MET following MEK inhibition was found to be due to inhibition of the ERK-dependent metalloprotease ADAM17, which normally inhibits c-MET signaling by promoting shedding of its endogenous antagonist, soluble "decoy" MET. Most importantly, pharmacological blockade of this resistance pathway with either c-MET or JAK1/2 inhibitors synergistically increased MEK-inhibitor-induced apoptosis and growth inhibition in vitro and in vivo in KRASMT models, providing clear rationales for the clinical assessment of these combinations in KRASMT CRC patients.

L'accord sujet-verbe en français contemporain: une étude de cas – <i>la/une foulei>

This article presents an analysis of synchronic variation and diachronic change in verbal agreement with the French noun <i>foulei>. This noun, like many collective nouns in French and other languages, can show variation between singular and plural verbal agreement (<i>la foule des habitants exultei>_SING<i> de joie dans les ruesi> vs. <i>une foule de gens pressés s'attardenti>_PLU). A novel combination of data, including data from sociolinguistic interviews, a gap-fill exercise, and a corpus of written French, is used to investigate this variation and change, to elucidate some of the factors that play a role in this type of agreement, and to examine the differences between this form used with the definite and indefinite determiner (<i>la foule i>vs. <i>une foulei>). Some theoretical issues concerning the definition of collective nouns are also addressed.

MErCuRIC1: A Phase I study of MEK1/2 inhibitor PD-0325901 with cMET inhibitor crizotinib in RASMT and RASWT (with aberrant c-MET) metastatic colorectal cancer (mCRC) patients.

Background: RAS is mutated (RASMT) in ~55% of mCRC, and phase III studies have shown that patients harbouring RAS mutations do not benefit from anti-EGFR MoAbs. In addition, ~50% of RAS Wild Type (RASWT) will not benefit from the addition of an EGFR MoAb to standard chemotherapy. Hence, novel treatment strategies are urgently needed for RASMT and > 50% of RASWT mCRC patients. c-MET is overexpressed in ~50-60%, amplified in ~2-3% and mutated in ~3-5% of mCRC. Recent preclinical studies have shown that c-MET is an important mediator of resistance to MEK inhibitors (i) in RASMT mCRC, and that combined MEKi/METi resulted in synergistic reduction in tumour growth in RASMT xenograft models (1). A number of recent studies have highlighted the role of c-MET in mediating primary/secondary resistance to anti-EGFR MoAbs in mCRC, suggesting that patient with RASWT tumours with aberrant c-MET (RASWT/c-MET+) may benefit from anti-c-MET targeted therapies (2). These preclinical data supported the further clinical evaluation of combined MEKi/METi treatment in RASMT and RASWT CRC patients with aberrant c-MET signalling (overexpression, amplification or mutation; RASWT/c-MET+). Methods: MErCuRIC1 is a phase I combination study of METi crizotinib with MEKi PD-0325901. The dose escalation phase, utilizing a rolling six design, recruits 12-24 patients with advanced solid tumours and aims to assess safety/toxicity of combination, recommended phase II (RPII) dose, pharmacokinetics (PK) and pharmacodynamics (PD) (pERK1/2 in PBMC and tumour; soluble c-MET). In the dose expansion phase an additional 30-42 RASMT and RASWT/c-MET mCRC patients with biopsiable disease will be treated at the RPII dose to further evaluate safety, PK, PD and treatment response. In the dose expansion phase additional biopsy and blood samples will be obtained to define mechanisms of response/resistance to crizotinib/PD-0325901 therapy. Enrolment into the dose escalation phase began in December 2014 with cohort 1 still ongoing. EudraCT registry number: 2014-000463-40. (1) Van Schaeybroeck S et al.
