Повний текст джерелаTriple-negative breast cancer and pancreatic adenocarcinoma are associated to very low survival-rates due to their high resistance to conventional treatments, posing significant public healthiness issue. The development of new targeted therapeutic options is then crucial. G-rich sequences in nucleic acids can form non-conventional secondary structures, known as G-quadruplexes, identified in telomeric sequences and in the promoters of potent oncogenes, such as cMYC, cKIT, and BCL2. These structures play a critical role in regulating gene expression, making them as promising therapeutic targets in cancer treatment.In this study, we employed a transdisciplinary approach, integrating chemical synthesis, molecular dynamic simulations, and cellular and molecular biology, to identify novel G-quadruplex binders and stabilizers aimed at controlling cancer progression. Previous work in our laboratory demonstrated that symmetric planar metal complexes could specifically bind these structures. In that sense, we synthesized 12 new transition metal complexes of Zn2+, Ni2+, Cu2+, Pd2+ and Pt2+, from the Salphen scaffold. Their ability to selectively bind and stabilize G-quadruplexes over double-stranded DNA were confirmed. Molecular dynamic simulations revealed an unconventional binding mode involving interaction with the G-quadruplex loop.Immunofluorescence assays confirmed that the compounds enhance G-quadruplex formation, in cancer cell lines, leading to the early downregulation of several G-quadruplex-driven oncogenes, such as kRAS, RET, and cMYC. This downregulation reduced cancer cell proliferation and viability, with less effect on non-cancerous cells.Some complexes induced apoptosis in cancer cells without affecting the non-neoplastic cells, after decreased hRAS and cMYC transcript levels, while other compounds caused DNA damage in pancreatic cancer cells T3M4. Notably, Zn2+ compounds increased VEGF-A expression, enhancing its transcription. We also investigated the effects of G-quadruplex stabilization on macrophages polarization, showing that nickel compounds promoted the polarization of M0 macrophages towards the anticancer M1 phenotype, while inhibiting the acquisition of pro-tumoral M2 markers.Overall, our novel metal complexes demonstrate significant potential in stabilizing G-quadruplex and exhibit promising anticancer properties, including modulation of the tumor microenvironment. These preliminary results suggest avenues for further research, with potential implications for advancing strategies in cancer therapy

Повний текст джерелаThe NPM-ALK chimeric protein is expressed in 75% of Anaplastic Large Cell Lymphomas. Although the oncogenic features of these lymphomas are in part due to the constitutive activation of many signalling pathways such as MAPK, PI3K/AKT, Jak/STAT et PLC-gamma, the identification of new partners of NPM-ALK would allow to consider new molecular mechanisms that could also participate to this phenotype. Thereby, interactions between NPM-ALK and RNA-Binding Proteins (RBPs) led us to postulate that, in addition to its recognized role in transcriptional activation, the oncogenic tyrosine kinase NPM-ALK could also modulate gene expression at the post-transcriptional level. In the first part of my work (1st article), I have shown that HuR, an AU-rich Binding Protein (AUBP), that bind to Adenine and Uridine rich elements (ARE) in the 3' untranslated region of some mRNAs, controls the stability and the level of translation of C/EBP-beta mRNA in ALK+ ALCL. I have also demonstrated that the tyrosine kinase NPM-ALK increases HuR activity by modulating its biological properties such as its binding affinity on its mRNA targets or its recruitment into actively translating polysomes. Lastly, we have determinated that NPM-ALK and HuR colocalize into cytoplasmic granules and that HuR is phosphorylated on tyrosine residus in ALK+ ALCL. In the second part of my work (publication in prep. ), by testing different point mutated versions of HuR, I have: 1/ identified the tyrosine residues that are phosphorylated in ALK+ ALCL; 2/ demonstrated the direct involvement of the tyrosine kinase NPM-ALK in this phosphorylation event; 3/ measured the impact of these phosphorylations on HuR biological properties (affinity toward its targets mRNAs and subcellular localization). More particularly, I have shown that the phosphorylation on tyrosine residue 26 within the RNA recognition motif (RRM) 1 is essential for NPM-ALK-mediated HuR binding to ARE-mRNAs. It remains now to clarify the role of these phosphorylations in the recruitment of HuR into polysomes and to demonstrate the functional relevance of these phosphorylations on the emergence and the maintenance of ALK+ ALCL. In the same time, I have taken part in another work in the team dealing with the role of the tyrosine kinase NPM-ALK in the control of miRNA expression, by methylation events. This project focused on the example of the control of the expression of the anti-apoptotic MCL-1 by miR-29a

Повний текст джерелаActivation of calcineurin (Cn), a calcium-dependant protein phosphatase, leads to dephosphorylation of its substrates including transcription factors of the NFAT family (NFATcl-c4). Calcineurin/NFAT signaling pathway, important to many aspects of T-cell biology, is activated in lymphoid malignancies and in mouse models of human T-cell acute lymphoblastic leukemias (T-ALL). Pharmacological inactivation of Cn with Cyclosporin A and FK506 shows anti-leukemic effects in T-ALL mouse models. To investigate the intrinsic function of Cn in leukemic cells, we generated mouse models of human T-ALL in which Cn can be specifically inactivated in tumor cells. We found that Cn activation in leukemic cells is under stromal control and that Cn inactivation alters physical and functional interactions that leukemic cells establish with their microenvironment. We show that Cn favours but is not required for in vivo expansion of leukemic blasts. However, Cn is critical for leukemia-initiating cells activity as analyzed in transplantation studies. These findings indicate that Cn is a promising target to prevent T-ALL relapse and call for clinical trials incorporating Cn inhibitors during consolidation therapy. Furthermore, we show in these mouse T-ALL models that inactivation of only one NFAT factor is not sufficient to prevent leukemogenesis. These fmdings suggest that either NFAT transcription factors are not calcineurin effectors in T-ALL or that NFAT factors have redundant functions in T-cell leukemogenesis
