Full textThe receptor tyrosine kinase Met and its ligand, the hepatocyte growth factor, are essential to embryonic development, whereas deregulation of Met signaling is associated with tumorigenesis. While ligand-activated Met promotes survival, caspase-dependent generation of the p40 Met fragment leads to apoptosis induction, hallmark of the dependence receptor. We show that although p40 Met contains the entire kinase domain, it amplifies apoptosis independently of kinase activity. In cell cultures and mouse liver undergoing apoptosis, the fragment shows a mitochondrial localization, required for p40-Met-induced cell death. Interestingly, p40 Met exhibits a BH3-like domain overlapping with its ATP-binding site and required for the apoptotic response. It induces mitochondrial permeabilization, while Met silencing delays this response. This demonstrates the involvement of receptor cleavage in regulating mitochondrial cell death. The Met dependence receptor thus displays overlapping kinase and BH3 domains, the former involved in survival, the latter in cell death via the intrinsic apoptosis pathway

Full textSignalling dysregulation of receptor tyrosine kinase Met and its ligand the HGF/SF (Hepatocyte Growth Factor/Scatter Factors) is associated with tumor growth and metastasis in numerous cancer. Iin stress condition and without its ligand, Met is cleaved by caspases in the juxtamembrane domain which liberates a proapoptotic fragment in cytoplasm, p40 Met. I have shown that a C-terminal cleavage of Met creates a hierarchical organization of these cleavages. The C-terminal cleavage of Met receptor is important to generate apoptotic fragment but does not affect the biological responses induced by the HGF/SF. On the other hand, Met is targeted by PreSenilin-dependent Regulated Intramembrane Proteolysis (called PS-RIP). This proteolytic process of degradation involves two sequential cleavages by membranous metalloproteases and by g-secretase complex. These cleavages regulate half-life of Met receptor and prevent its activation without ligand.Following the cleavage by metalloproteases, Met can escape from g-secretase complex through its prior internalization. Generated fragments are then degraded by the lysosome. Fragments of both degradation patways are able to transform fibroblasts. Interestingly, human tumor xenografts in mice display accumulation of these fragments, suggesting these PS-RIP and lysosomal degradations pathways prevent accumulation of deleterious fragments of Met.Different cleavages of Met receptor can regulate its action without HGF/SF and could have an important role in physiological responses

Full textThe effect of polysaccharides on HGF-MET interaction was studied using an experimental design with several microarrays under different experimental conditions. The purpose of the analysis is the selection of the best polysaccharides, inhibitors of HGF-MET interaction. From a statistical point of view this is a classification problem. Statistical and computer processing of the obtained microarrays requires the implementation of the PASE platform with statistical analysis plug-ins for this type of data. The main feature of these statistical data is the repeated measurements: the experiment was repeated on 5 microarrays and all studied polysaccharides are replicated 3 times on each microarray. We are no longer in the classical case of globally independent data, we only have independence at inter-subjects and intra-subject levels. We propose mixed models for data normalization and representation of subjects by the empirical cumulative distribution function. The use of the Kolmogorov-Smirnov statistic appears natural in this context and we study its behavior in the classification algorithms like hierarchical classification and k-means. The choice of the number of clusters and the number of repetitions needed for a robust classification are discussed in detail. The robustness of this methodology is measured by simulations and applied to HGF-MET data. The results helped the biologists and chemists from the Institute of Biology of Lille to choose the best polysaccharides in tests conducted by them. Some of these results also confirmed the intuition of the researchers. The R scripts implementing this methodology are integrated into the platform PASE. The use of functional data analysis on such data is part of the immediate future work

Full textMet receptor activation by its ligand, Heptocyte Growth Factor, induces cell responses necessary for embryonic development such as cell survival or motility. However, its deregulation is involved in tumorigenesis. My laboratory previously showed that Met activity is regulated by proteolytic cleavage. Indeed, PreSenilin-dependent Regulated Intramembrane Proteolysis (or PS-RIP), two sequential cleavages mediated by membrane metalloproteases and the γ-secretase complex, controls Met half-life. Following apoptotic stress, Met is also cleaved by caspases into an intracellular fragment which amplifies apoptosis.I showed that Met is targeted by calpains, another protease family mediating two different cleavages in two different cellular contexts. Indeed, the R970C Met mutation or high cell density induces cleavage of Met into a fragment about 45kDa, p45 Met, which translocates in the nucleus and favors cell scattering and motility, suggesting it is involved in cell transformation. On the other hand, during necrosis induced by calcium stress, Met receptor is cleaved by both calpains and metalloproteases. Although the generated fragments do not seem to have biological properties, these two cleavages mediate an efficient degradation of Met receptor and consequently inhibiting of the survival signals it can provide. Interestingly, these fragments are detected in lung cancer samples overexpressing Met indicating that proteolytic cleavages of Met we identified have a pathological relevance
