Crosstalk between chronic myelogenous leukemia (CML)and bone marrow stromal cells: role of exosomes in the IL8- dependent signalling mediated by EGFR…
2014
Introduction: CML is a myeloproliferative disorder characterized by Bcr-Abl oncoprotein with a constitutive tyr-kinase activity. Exosomes (exo) shed by cancer cells potentially affect tumor-stroma interaction through the establishment of a bi-directional crosstalk. Interleukin-8 (IL8) is a proinflammatory chemokine that regulate proliferation and survival of cancer cells. We previously demonstrated that CML-derived exo modulate bone marrow microenvironment through the IL8 secretion from stromal cells. EGFR, as well as IL8, regulate cell proliferation and survival; it has been recently demonstrated that EGFR ligands can signal via exosomes shed by cancer cells. We hypothesized that the effec…

X-ray irradiation influence on prototype Er3+-optical fibers: confocal luminescence study
2010
International audience; The integration of rare-earth doped optical fibers as part of fiber-based systems in space implies the development of waveguides tolerant to the radiation levels associated with the space missions. We report the spatial distribution, the photoluminescence (PL) properties of color centers and the related changes induced by X-rays radiation at different doses (50, 500 and 1000 krad) for two different prototypes of Er-doped optical fibers. Each sample (in the version pristine, X-irradiated and H2 loaded prior to radiation exposure) was characterized by confocal microscopy luminescence (CML) measurements in Visible range with Visible (488 nm) or UV (325 nm) laser light e…
