Full textNeurotensin (NT) can act in periphery and in the central nervous system. Two of this receptors are G protein coupled receptors (NTSR1 and NTSR2) and the third, is a type I receptor with one transmembrane domain (NTSR3 or sortilin). NT and NTSR1 are both implicated in tumoral progression and there are overexpressed in a lot of cancer. NT induces proliferation of cancerous cells which are mediated by NTSR1 which may transactivate the Epidermal Growth Factor Receptor (EGFR). We demonstrated that NT doesn’t transactivate the EGFR in HT29 cell line, a human adenocarcinoma of colon. NTSR3 is a multifunctional protein, is implicated in sorting of proteins, proliferation, differenciation… Moreover, once at the plasma membrane, NTSR3 can be hydrolysed and freed in a soluble form, in the extracellular medium (sNTSR3). During my PhD, I demonstrated that the sNTSR3 is an active molecule with a biological activity, as it induces the release of intracellular calcium. The sNTSR3 activates intracellular signaling like the complex FAK-Src, PKCα and Pi3K pathway, leading to an increase in cancerous cell adhesion. Furthermore, sNTSR3 increases E-Cadherin expression, space between cells and enhances the proliferation induced by EGF. Taken together, these results indicate that the soluble form of NTSR3 can be implicated in tumoral progression

Full textPeroxisome proliferator-activated receptors (PPAR) are transcription factors belonging to the nuclear receptor family. Three isotypes of PPAR have been described in humans (a, NUC-1 also called b or d; and g). PPAR have been implicated in a variety of biological processes including colon cancer. We have studied the expression of PPAR in colonic tissues in three biological situations: during development of the human fetal digestive tract, in Caco-2 cells used as a model of enterocyte-like differentiation and in biopsies from tumoral and normal adjacent human colon. The PPAR subtypes are expressed as early as 7 weeks of foetus development in cell types of endoderm and mesoderm origins. The presence of PPARg protein is found by Western blotting and that of the encoding mRNA by nuclease-S1 protection assay, confirming that this subtype is not adipocyte-specific. PPARa, PPARb and PPARg exhibit different spatio-temporal patterns of expression during morphogenesis of the digestive tract. Whatever the stage and the gut region (except the stomach) examined, PPARg is expressed at a high level, suggesting some fundamental role for this receptor in development and/or physiology of the human digestive tract. The expression of PPARa and g was next studied in Caco-2 cells. This cell line exhibits enterocyte-like differentiation during long term culture. We showed by immunohistochemistry that both isotype protein levels increased gradually during cell differentiation Using Nuclease S1 protection assay, we demonstrated that there is not a concomitant increase in the transcriptional level of PPAR subtypes, especially PPARa and isoforme PPARg2 which seemed to be regulated at the translational level. Since PPARg has been involved in human colon carcinoma, we finally investigated the expression of this PPAR subtype in biopsies obtained from human colon adenocarcinoma. At the transcriptional level, PPARg was less abundant in tumours than in normal-paired tissues. In contrast, using immunohistochemistry we showed that the PPARg protein amount was more abundant in tumoral tissues. In addition PPARg immunostaining was exclusively found in cytoplasm. Moreover, in normal adjacent tissues PPARg was present in the upper one-third of the crypts suggesting that PPARg expression is associated to the differentiation/maturation process of columnar cells

Full textThe hyaluronique acid (HA) is one of the main elements of the extracellular matrix. The role of the membrane HA receptors (CD44, RHAMM) and hyaluronidases are still controversial. We thus developed the production of HA hydrogels, in which we studied the differenciation and the proliferation of cancer cells and haematopoietic stem cells (HSC). The hydrogel invasion is dependent on the production of hyaluronidase but other factors contribute to it (regulation of CD44 activity, HA secretion). At the same time, we demonstrated that in 3D culture the cancer cells were much more resistant to the antimitotics than in usual culture. Finally, the HA hydrogels allowed us to obtain a culture medium close to the bone marrow microenvironment, compatible with not only HSC survival (until 6 months) but also growth and differenciation
