Monounsaturated fatly acid metabolism and colon cancer cells proliferation : role of Stearoyl-CoA desaturase-1 and effect of conjugated linoleic acid…
2012
Cancer cells adapt their metabolism in response to signals from the microenvironment and proliferation. Thus, MonoUnsaturated Fatty Acid (MUFA) synthesis is increased in colon cancer cells, and associated with increased Stearoyl-CoA Desaturase (SCD) activity, the rate limiting enzyme of MUFA biosynthesis. Polyunsaturated Fatty Acid (PUFA), as isomers of conjugated linoleic acid (CLA), exert inhibitor activity on SCD-1 and have anti-cancer properties, but their mechanisms are not yet clear. In this context, the aim of this work was first to evaluate the role of SCD-1 in the proliferation of colon cancer cells (CCC) and to define the underlying mechanisms. In a second time, we provide new inf…

Growth and activities of enzymes of primary metabolism in batch cultures of Catharanthus roseus cell suspension under different pCO2 conditions
1988
In vitro enzyme activities of glycolysis, pentose-phosphate pathway and dark CO2 fixation were assayed in batch cultures of heterotrophic Catharanthus roseus cells under various gassing rates and partial pressures of carbon dioxide. Detrimental effects of low pCO2 culture conditions on the growth characteristics could be linked to marked changes in levels of enzymes of primary metabolism during growth. The enzyme levels observed during the early stages of growth were found to be more stable when a constant pCO2 (20 mbar) was maintained and enabled exponential growth to be reached more rapidly. The importance of carbon dioxide as a “conditioning factor” of the culture medium is discussed.

Action immunitaire de chimiothérapies anticancéreuses : un exemple à travers les modes d'actions des cellules "Interferon-producting Killer Dendritic…
2009
Classical antitumoral therapies are basically perceived as a direct and lytic action of the chosen therapeutic agent against tumor cells. Nevertheless, growing evidence indicates that some anticancer strategies can work through the action of the immune system. Imatinib Mesylate (IM), a targeted drug, helped us to unravel some mechanisms of action of a natural killer sub-population: the "Interferon-producing Killer dendritic Cells" (IKDC). Thoses cells possess anti-tumoral lytic capacities, synergistically amplified by IM and interleukine (IL)-2, under the dependency of IL-15, and also antigen-presenting capability. Those cells are capable of TRAIL-mediated lysis and of antigen uptake, proce…
