Full textIt has been shown that SK3 channel was a mediator of breast cancer cells migration, a fundamental property for metastasis formation. In addition, edelfosine inhibits SK3 channel. This ether-lipid owns a high anti cancerous potential in vitro but its clinical use was hampered by some side effects, Firstly, we showed the structural parts of edelfosine required for SK3 channel inhibition and cell motility inhibition. Moreover, we selected Ohmline (1-O-Hexadécyl-2-O-Méthyl-sn-glycéro-lactose), an edlefosine’s analogue that preserves SK3 channel and motility inhibitory properties. Secondly, we evaluated this lipid on tumor development in nude mice model. We showed that this lipid reduces metastasis formation without effect on primary tumor. To conclude, we described Ohmline, the first lipid inhibitor of SK3. This compound should become the first member of a new family of metastasis lipid inhibitors

Full textMammary gland morphogenesis results from the coordination of different pathways, including apoptosis, proliferation, differentiation, and stem/progenitor cell dynamics. Epithelial-mesenchymal transition (EMT) appears to be involved in these signalling pathways. Thus, we focused on transcription factor Slug, a key gene regulating EMT, and its involvement in mammary gland morphogenesis. First, using a Slug–LacZ transgenic mice model, we located Slug in a subpopulation covering about 10–20% basal duct cells and cap cells of terminal end bud, coexpressed with basal markers P-cadherin, CK5 and CD49f. Then, we have shown by in vitro experiments of loss and gain of function that Slug regulated the differentiation and proliferation of mammary epithelial cells. Moreover, we found that Slug inhibited apoptosis, promoted cell motility, and allowed the emergence and growth of clonal mammospheres. This last point shows the involvement of Slug in stem cells, which is reinforced by the fact that primary cells deficient for Slug were unable to give secondary mammospheres. Furthermore, we observed in vivo that mice deficient for Slug showed delayed development of the mammary gland, with less proliferating cells, and overexpression of markers of luminal cells CK8/18, GATA3 and ER. Other genes regulating EMT are found overexpressed, suggesting a compensatory mechanism, which can explain the fact that the delayed development of the mammary gland is caught up in adulthood. The Slug-knockout mammary glands also showed overbranching, evoking an early differentiation, similar to the mammary glands of mice deficient in P-cadherin, expressed in the basal cells. Knowing this, we found that P-cadherin was decreased in Slug-knockout mammary glands, and in CommaDβ cells treated with siRNA targeting Slug. We then found that Slug binds directly to the promoter of the P-cadherin and activated it, and that P-cadherin was involved in some functional effects of Slug, such as mammospheres growth, differentiation and cell migration. Thus, we have shown the importance of a new signalling pathway Slug/P-cadherin in the capacity of mammary epithelial stem/progenitor cells, integrating differentiation and cell motility, and we now have a better understanding of its role in the aggressiveness of some breast cancers
Biondini, Marco. "RALlying through cell motility and invasion." Thesis, Paris 11, 2014. http://www.theses.fr/2014PA11T042.
Full textMetastasis is a multistep process by which cancer cells migrate away from the primary neoplastic mass to give rise to secondary tumors at distant sites. Thus, the acquisition of motility and invasive traits by tumor cells is a crucial step for metastasis to occur. Depending on the cell type and the environment, cells can move collectively keeping stable cell-cell contacts or as individual cells, which translocate by exploiting either mesenchymal or amoeboid motility programs.Different molecules and pathways have been linked to the regulation of cell motility. Rho small GTPases (Rac1, Cdc42 and RhoA) control cell migration through their actions on actin assembly, actomyosin contractility and microtubules. Rac1 drives mesenchymal-type motility by promoting lamellipodia formation via the Wave Regulator Complex (WRC). On the contrary, amoeboid motility is governed by RhoA which promotes cell movement via the generation of actomyosin contractile force. Another family of small GTPases, the Ral proteins, was recently involved in the regulation of cell migration. RalB, through the mobilization of its main effector the Exocyst complex, was shown to play an essential role in cell motility. In this work of thesis we investigated the molecular mechanisms through which RalB/Exocyst pathway controls cell motility and invasion.In the first part of this manuscript we show that Exocyst interacts with the RacGAP SH3BP1 (project 1). In mesenchymal moving cells Exocyst/SH3BP1 interaction is required to organize membrane protrusion formation by spatially regulating the activity of Rac1 at the cellular front. In addition, in project 2, we show that the Exocyst binds to the wave regulator complex (WRC), a key promoter of actin polymerization. We provide evidences for Exocyst to be involved in driving the WRC to the leading edge of motile cells, where it can stimulate actin polymerization and membrane protrusions. Reactivation of a developmental program termed epithelial-mesenchymal transition (EMT) was recently shown to promote motility, invasion and metastasis of neoplastic cells. Tumor cells undergoing EMT loose cell-cell contacts acquire a fibroblastoid phenotype and invade the surrounding tissues as individual cells. In project 3 we characterized the invasion plasticity of cancer cells after EMT and we investigated the molecular contribution of Ral to post-EMT invasion. We showed that upon EMT cells disseminate individually in a Rho-driven fashion exploiting the generation of actomyosin force to deform the extracellular matrix. We document that RalB silencing severely impairs actomyosin contractility and dissemination of post-EMT cells. We hypothesize that RalB regulates invasion by controlling the dynamics of the Rho pathway via the Exocyst-associated RhoGEF GEF-H1 in post-EMT cells. Finally, in the last part of this thesis manuscript, we present the PIV-based “AVeMap” software which has been developed to quantify in a fully automated way cell migration and its parameters (Project 4).Taken together the results presented in this thesis manuscript point out the Ral/Exocyst pathway as a key molecular organizer of the execution of both Rac1- and Rho-driven motility programs

Full textMetastasis is a multistep process by which cancer cells migrate awayfrom the primary neoplastic mass to give rise to secondary tumors at distantsites. Thus, the acquisition of motility and invasive traits by tumor cells is acrucial step for metastasis to occur. Mutational activation of Ras proteinspromotes oncogenesis by disturbing a multitude of molecules andpathways that participate to the regulation of several processes includingalso cell invasion and motility. Among them a central role is played by Rhosmall GTPases (Rac1, Cdc42 and RhoA) which control cell migrationthrough their actions on actin assembly, actomyosin contractility andmicrotubules. Rac1 drives mesenchymal-type motility by promotinglamellipodia formation via the Wave Regulator Complex (WRC), a keypromoter of actin polymerization. Another family of small GTPases that actdownstream Ras, the Ral proteins, has been recently involved in theregulation of cell migration. RalB, through the mobilization of its maineffector the Exocyst complex, was shown to play an essential role in cellmotility. In this work of thesis, we investigated the molecular mechanismsthrough which RalB/Exocyst pathway controls cell motility and invasiondownstream oncogenic Ras.In the first part of this manuscript we describe the identification andcharacterization of the WRC complex as a novel interactor of the Exocyst.Furthermore, we provide evidences for Exocyst to be involved in drivingthe WRC to the leading edge of motile cells. This hypothesis, was finallydemonstrated in the second part of the manuscript. We were able to definethe mechanisms underlying the function of RalB in invasion by exploitingan optogenetic approach. We found that RalB, activated by Ras via the2Rgl1 and Rgl2 exchange factors, mobilizes the Exocyst complex whichrecruits the Wave Regulatory Complex (WRC) at cell edge, promotingprotrusions, migration and invasion. Even more, we show that the Rac1GTPase, usually considered the master of cell protrusions, is not involvedin this process. Finally, we analyzed Ral proteins expression in a cohort ofbreast cancer samples, pointing out for the first time an accumulation ofRalB in the invasive and metastasis compartments, suggesting a role ofRalB in invasiveness and metastatic spread of human breast cancers. Takentogether our work contribute to light up the role of the underestimated Ralpathway in the context of cancer invasion

Full textAs a tumor grows, it exerts a mechanical pressure on its surrounding tissue and is compressed back as a reaction. Recent experiments on an in vitro tumor model, called spheroid, have shown that this pressure is crucial for the fate of the cancerous tissue. In particular, the pressure slows down its growth, but makes it more invasive. To further understand the latter effect, we decided to study the migration of cells inside spheroids under pressure. However, imaging the inside of a spheroid is technically challenging as usual microscopy methods do not work on thick tissues (> 100 μm). Standard imaging methods are limited in terms of depth penetration because of light scattering. For this reason, we decided to take advantage of this scattered light with a method called Dynamic Light Scattering (DLS). We developed its application to cell migration in order to measure the distribution of cells displacements over time. The measurement is label-free and works with spheroids as thick as 400 μm in diameter. By this means, we revealed a radial organization inside the spheroid in terms of mobility, with fast cells at the surface and slower cells in the core. We also showed that applying a pressure onto spheroids decreases the average cell speed by a factor up to two for pressure greater than 15 kPa. Another team reported an increase in the speed of cells located at the surface of a compressed spheroid, which implies that the radial organization is also true for the impact of pressure. We demonstrated that this sensitivity to an external pressure is a 3D emergent property, in which the extracellular matrix plays an essential role. Finally, we explored the potential of our technique by addressing another question: how do apoptotic cells signals affect the migration of macrophages? We found that early apoptotic cells increase the speed of macrophages whereas late apoptotic cells decrease it. In both cases, the persistence length of the motion is the same

Full textIn most cases of cancer, metastasis and not the primary tumor per se is the main cause of mortality. To establish secondary growth in distant organs cancer cells must develop an enhanced propensity to migrate. The key objective of this thesis proposes that some actors of Ca2+ signaling (Orai, and TRPC, STIM) coupled to SK3 channel would form complexes that play a critical role in cell migration of various cancers (breast, colon and prostate). Furthermore we showed that the localization of these channels complexes in lipid-rafts is essential to their regulation and function. Thus, the delocalization of these complexes of lipid-raft outside by alkyl-phospholipids could be a new way to modulate the SK3/Ca2+ dependent cell migration and metastasis development
