α2β1-integrin signaling by itself controls G1/S transition in a human adenocarcinoma cell line (Caco-2): implication of NADPH oxidase-dependent production of ROS

Autor: Stéphane Honoré, Claudette Briand, Jean-Baptiste Rognoni, Hervé Kovacic, Véronique Pichard

Publikováno v: Experimental Cell Research. 285:59-71

In this work, we report that type IV collagen, mainly via alpha2beta1-integrin ligation, was able to induce cyclin expression and G1/S transition in a colic adenocarcinoma cell line (Caco-2) cultured without soluble growth factors or fetal bovine ser

Adhesion, actin cytoskeleton organisation and the spreading of colon adenocarcinoma cells induced by EGF are mediated by α2β1 integrin low clustering through focal adhesion kinase

Publikováno v: Histochemistry and Cell Biology. 116:337-348

Both epidermal growth factor (EGF) and the extracellular matrix components have been implicated in the pathobiology of adenocarcinomas by somewhat poorly understood mechanisms. We have addressed this problem using an in vitro model comprising the col

Up-regulation of α2β1 integrin cell-surface expresssion protects A431 cells from epidermal growth factor-induced apoptosis

Autor: Jean-Baptiste Rognoni, Pierre-Marie Martin, Stéphane Honoré, Claude Penel, Sophia Smida Rezgui

Publikováno v: International Journal of Cancer. 87:360-367

High epidermal growth factor (EGF) concentration (10–8 M) induces inhibition of A431 cell proliferation, resulting in part from an apoptotic process. For some cells escaping this process, proliferation was associated with a decrease in apoptosis. M

Combination of culture on collagen gels and glucose starvation for cloning human colon cancer cells

Autor: Jean-Baptiste Rognoni, Maxime Lehmann, Jacques Fantini, Jacques Marvaldi, Chantal Rabenandrasana, Bernard Verrier

Publikováno v: Cytotechnology. 5:117-127

Glucose starvation has been widely used to select differentiated subpopulations from the heterogenous human colon cancer cell line HT29. We observed that the important cell loss elicited by culturing these cells in glucose-free medium could be limite

Impaired carcinoembryonic antigen release during the process of suramin-induced differentiation of the human colic adenocarcinoma cell clone HT29-D4

Autor: Jacques Marvaldi, Jean-Baptiste Rognoni, Jacques Fantini, Magali Theveniau, Gilbert Pommier

Publikováno v: Journal of Cellular Physiology. 143:468-474

The establishment of a differentiated state of the human colic adenocarcinoma cell clone HT29-D4 can be obtained by two ways: 1) the removal of glucose and its replacement by galactose in the culture medium (Fantini et al.: Biology of the Cell 65:163

Concomitant cell growth and differentiation are dependent on erbB1 and integrin activation in an autonomously surviving colon adenocarcinoma: involvement of autocrine amphiregulin secretion

Autor: Veronique, Picihard, Yolande, Berthois, Monique, Roccabianca, Charles, Prévôt, Marcel, Sarrazin, Henri, Portugal, Shant, Kumar, Pat, Kumar, Jean-Baptiste, Rognoni

Publikováno v: Anticancer research. 26(4B)

In normal colon epithelium, cell proliferation is followed by cell differentiation. The purpose of this work was to investigate, in the HT29-D4 colon adenocarcinoma cell line, the occurrence of a temporal sequence of changes in cell proliferation and

[Involvement of FAK, PI3-K and PKC in cell adhesion induced by microtubule disruption]

Autor: Azzeddine, Kadi, Virginie, Berthet, Véronique, Pichard, Brigitte, Abadie, Jean-Baptiste, Rognoni, Jacques, Marvaldi, José, Luis

Publikováno v: Bulletin du cancer. 89(2)

We have previously shown that microtubule disruption results in an increase in cell adhesion to ECM proteins. In this work we show that this enhanced cell attachment was completely abolished by specific inhibitors of tyrosine-kinases, PI3-K and PKCs.

Publikováno v: Histochemistry and cell biology. 114(4)

We investigated in a colon adenocarcinoma cell line, the exclusive role of extracellular matrix (ECM) components in the absence of soluble factors regarding the integrin clustering processes, and their implication in cell adhesion, spreading and orga

Publikováno v: British Journal of Cancer

The human colon adenocarcinoma HT29-D4 cell line is an interesting model for studies on epithelial cell differentiation. Undifferentiated cells are malignant proliferating cells, whereas differentiated cells act like epithelial polarized cells. In th

Publikováno v: Differentiation; research in biological diversity. 63(5)

The aim of this work was to show in serum-free medium a convergent effect of physiological factors and extracellular matrix proteins on the differentiation process of enterocytes by taking as a model the HT29-D4 clone that has the feature of differen
