[more ▼] The commonly accepted model of STAT factor activation at the cytoplasmic part of the receptor assumes that signal transducers and activators of transcription (STATs) are recruited from a cytoplasmic pool of monomeric STAT proteins. Based on a previous observation that non-phosphorylated STAT3-Src homology 2 domains dimerize in vitro, we investigated whether the observed dimerization is of physiological relevance within the cellular context. We show that STAT1 and STAT3 are pre-associated in non-stimulated cells. Apparently, these complexes are not able to translocate into the nucleus. We provide evidence that the event of STAT activation is more complex than previously assumed.

[more ▼] Coumarins are natural compounds with antioxidant, anti-inflammatory and anti-cancer potential known to modulate inflammatory pathways. Here, non-toxic biscoumarin OT52 strongly inhibited proliferation of non-small cell lung cancer cells with KRAS mutations, inhibited stem-like characteristics by reducing aldehyde dehydrogenase expression and abrogated spheroid formation capacity. This cytostatic effect was characterized by cell cycle arrest and onset of senescence concomitant with endoplasmic reticulum and Golgi stress, leading to metabolic alterations. Mechanistically, this cellular response was associated with the novel capacity of biscoumarin OT52 to inhibit STAT3 transactivation and expression of its target genes linked to proliferation. These results were validated by computational docking of OT52 to the STAT3 DNA-binding domain. Combination treatments of OT52 with subtoxic concentrations of Bcl-xL and Mcl-1-targeting BH3 protein inhibitors triggered synergistic immunogenic cell death validated in colony formation assays as well as in vivo by zebrafish xenografts.

[more ▼] APO-1 (Fas/CD95), a member of the tumor necrosis factor receptor superfamily, induces apoptosis upon receptor oligomerization. In a search to identify intracellular signaling molecules coupling to oligomerized APO-1, several cytotoxicity-dependent APO-1-associated proteins (CAP) were immunoprecipitated from the apoptosis-sensitive human leukemic T cell line HUT78 and the lymphoblastoid B cell line SKW6.4. CAP1-3 (27-29 kDa) and CAP4 (55 kDa), instantly detectable after the crosslinking of APO-1, were associated only with aggregated (the signaling form of APO-1) and not with monomeric APO-1. CAP1 and CAP2 were identified as serine phosphorylated MORT1/FADD. The association of CAP1-4 with APO-1 was not observed with C-terminally truncated non-signaling APO-1. In addition, CAP1 and CAP2 did not associate with an APO-1 cytoplasmic tail carrying the lprcg amino acid replacement. Moreover, no APO-1-CAP association was found in the APO-1+, anti-APO-1-resistant pre-B cell line Boe. Our data suggest that in vivo CAP1-4 are the APO-1 apoptosis-transducing molecules.

[more ▼] Cet article s’intéresse à trois œuvres qu’à priori tout oppose : Le Cantique des Cantiques, Phèdre de Jean Racine et Partage de midi de Paul Claudel. À l’instar des protagonistes du Cantique des Cantiques, Hippolyte et Aricie (Phèdre de Jean Racine) et Mesa et Ysé (Partage de midi de Paul Claudel) sont des êtres qui vivent un amour initiatique. Ils n’ont de cesse de se fuir et de se (re) chercher. C’est la nostalgie d’Éros et d’Agapé. En tant que drame du désir, de l’amour et de l’altérité intrinsèque à l’humanité et en tant que texte biblique axé sur l’amour et la prière, Le Cantique des Cantiques fait l’objet de nombreuses relectures et de commentaires divers et variés. La problématique à laquelle se consacre cet article est : « comment et pourquoi pouvons-nous considérer Hippolyte et Aricie dans Phèdre de Jean Racine et Mesa et Ysé dans Partage de midi de Paul Claudel comme étant des figures archétypales modernes du Cantique des Cantiques ? ». Pour tenter de répondre à cette problématique, cinq critères vont nous guider tout au long de notre étude : le lyrisme formel, un espace ouvert et fermé, la présence et l’absence, la féminité et le sacré.
