Team : Senescence, fibrosis and cancer
Our team “Senescence, fibrosis and cancer” (acronym: SENFIB) is composed of researchers, associate professors, clinicians joining their expertise, workforce and resources to develop basic and translational research programs on the impact of the two main forms of cellular aging (senescence and fibrosis) on cancer initiation as well as on cancer recurrence after dormancy.
In this context, the objectives of the team (schematized in the following figure) will be to decipher the interrelationships between senescence and fibrosis, to analyze their impact on tumorigenesis in the context of aging and in response to anti-cancer therapies and to search for new seno-fibrolytics that could eliminate these cells to decrease their impacts.
Our research is focused on:
- The search for common pathways controlling the establishment of senescence and fibrosis
- Deciphering some of the mechanisms by which senescence and fibrosis could favor the first steps of carcinogenesis
- Finding new targets for seno-fibrolytics amongst non-coding RNAs
Overall, our team is involved in new fundamental knowledge about the molecular regulation of senescence and fibrosis, two related age-associated and anti-cancer therapy-induced cell states. Interdisciplinary projects with bioinformaticians and statisticians will help to develop new original models of the molecular networks. Our project would also provide some evidence of the impact of these reprogrammed cell states on cancer initiation and cancer cell resistance to therapy through cell autonomous mechanisms of tumor cell dormancy or through alteration of the microenvironnement. Translational programs involving the clinician of the team as well as collaborations with the Centre Oscar Lambret and OncoVet will enable to evaluate the potential of eliminating senescent and/or fibrotic cells as new therapies to prevent the initiation of post-treatment second neo-cancers or to decrease cancer cell resistance to therapy, entry into dormancy and disease recurrence.

A- Molecular mechanisms of cellular senescence that impact on neoplastic transformation.
A.1- Senescence and post-senescence neoplastic emergence
The dominant paradigm in the field of senescence is that senescence is a cell-autonomous tumor-suppressor mechanism that the cell must bypass to become immortal and tumorigenic. As such, it is the first line of defense induced following an initial oncogenic activation. The experiments we performed in the team using NHDFs confirmed this concept. Indeed, in in vitro culture, NHDFs undergo an exponential growth phase followed by a senescence plateau, very stable, associated with shortened telomeres which induce a permanent DNA Damage Response (DDR) and an irreversible cell-cycle arrest (Nassour et al, Nature Commun, 2016). In contrast, NHEKs also undergo an exponential growth phase followed by a senescence plateau, but this latter is only transient and leads to two different outcomes. The main outcome is cell death that affects almost all cells. The alternative outcome affects only about one cell on 10,000. These cells re-enter cell cycle and generate clones of cells that re-proliferate. We have established by transcriptomic analyses that these post-senescence (PS) cells are transformed (Martin et al, Molecular cancer, 2014) and we have shown by xenograft assays in nude mice that they are tumorigenic (Gosselin et al, Cancer Res, 2009). We therefore called this phenomenon Post-Senescence Neoplastic Emergence (PSNE). Both senescent and PS NHEKs display still long telomeres, although the telomerase is not reactivated. PS cells are not the progeny of already transformed cells, or stem cells, that could have been present in the original tissue explant, but do originate from the division of fully senescent mother cells by an atypical mechanism of budding mitosis called neosis (Gosselin et al. Cancer Res, 2009). PSNE is not specific of keratinocytes: we described a similar phenomenon in Normal Mammary Epithelial cells (HMECs) (Nassour et al, Nature Commun, 2016).
A.2- Post-senescence neoplastic emergence proceeds by escaping autophagic cell death
By observing NHEK cultures, we hypothesized that those senescent cells which do not produce PS cells die, suggesting that PSNE could necessitate cell-death escape. To assay this hypothesis, we first needed to establish the mechanism of senescent cell death which was completely unknown. We demonstrated that senescent NHEKs do not die by apoptosis but following an overactivation of autophagy (Gosselin et al, Am J Pathol. 2009). We continued this work by searching what could induce this high autophagic activity. We have shown that the NF-kB>MnSOD>H2O2 pathway we demonstrated before to be involved in the occurrence of senescence in NHEKs (Bernard et al. Cancer Res 2004) was also responsible for the induction of the associated autophagic activity, through the induction of oxidative damages to mitochondria and nucleus (Deruy et al. Plos One, 2010). We further demonstrated that inhibiting autophagy in senescent NHEKs favors PSNE, formally demonstrating that PSNE indeed requires autophagic cell death escape. Interestingly, we also observed that autophagy inhibitors have a dose effect: at low doses, they favor PSNE, whereas at high doses they have a tendency to repress it, suggesting that senescent cells have to maintain a quality-control autophagic activity to be able to re-enter cell-cycle (Deruy et al, Cell Death and Disease, 2014).

A.3- Post-senescence neoplastic emergence occurs in consequence of unrepaired DNA single-strand breaks
The DNA Damage Response (DDR) and the following activation of the p53/p21 pathway are recognized as the main mechanism responsible for the robustness and irreversibility of the senescent cell-cycle arrest. It is induced following the shortening of telomeres or following an oncogenic activation . In the case of NHEKs and HMECs senescence, we have shown that this pathway is not activated.
Instead, senescence in these epithelial cells results from a mild oxidative stress, not high enough to induce DNA double-strand breaks (DSBs) and the activation of the DDR pathway, but enough to induce DNA single-strand breaks (SSBs). Importantly, the expression of PARP1, the first-line enzyme of SSB signalization, is decreased also in response to the oxidative stress. Consequently, the SSBs remain unrepaired and accumulate. This accumulation activates the p38MAPK which induces the up-regulation of the cell cycle inhibitor p16 and the cell cycle arrest. Counter-intuitively, we have shown that the accumulation of the unrepaired SSBs is also responsible for PSNE. Indeed, PSNE was abrogated by anti-oxidants and by re-expression of PARP1 (Nassour et al, Nature Commun, 2016).
Therefore, one major recurrent characteristic of senescence is the accumulation of unrepaired DNA damage. However, depending on the nature of the damage, the cell outcome largely differs. When the damage induces the DDR pathway, the senescent state is very stable and behaves as a cell-autonomous tumor suppressor state. In contrast, when the damage does not activate the DDR pathway but leads to the cell cycle arrest through p16 only and when it is associated with other organelles damages of oxidative origin, the senescent cells have two outcomes: almost all of them die by autophagy, and a few of them escape autophagic cell death and re-enter into the cell cycle. Because of the presence of unrepaired SSBs, the daughter cells acquire some mutations and neoplastic properties. Such a senescence mechanism is therefore oncogenic. Importantly, we evidenced these two types of senescence in tissue sections of human skin, the first one in fibroblasts of the dermis, the second one in keratinocytes of the epidermis (Nassour et al, Nature Commun, 2016).
We have written three review papers arguing on the mechanisms and specificities of senescence in epithelial cells (Nassour and Abbadie, Molecular and Cellular Oncology, 2016; Abbadie et al, Cellular and molecular Life Sciences, 2017; Goy and Abbadie, Medecine/Sciences, 2018).

A.4- The senescent fibroblast secretome enhances early skin carcinogenic events
Another well demonstrated paradigm in the field of senescence is that, despite being in a cell-autonomous tumor suppressor state, a senescent fibroblast produces a modified secretome -the senescence-associated secretory phenotype (SASP)- which has paracrine inflammatory and tumor-promoting effects on already pre-transformed epithelial cells, but not on normal epithelial cells. We took advantage of our model of PSNE to investigate whether the SASP could also be able to stimulate the very early phases of carcinogenesis. We demonstrated that a culture medium conditioned by senescent NHDFs was able to increase the PSNE frequency and to increase the epithelium-mesenchyme transition of the very first PS NHEKs. We highlighted matrix metalloproteinases 1 and 2 (MMP1 and MMP2) as the main components of the SASP responsible for these changes. We identified the Protease Activated Receptor 1 (PAR1) as a receptor specifically overexpressed in PS NHEKs, activated by MMP1 and MMP2 and transducing the epithelium-mesenchyme transition changes (Malaquin et al. Plos One 2013).

A.5- Cellular senescence involves an intracrine prostaglandin E2 pathway in NHDFs
Lipid mediators such as prostaglandins could also be components of the protumorigenic SASP besides already described cytokines, growth factors and MMPs. We had shown a few years ago that COX-2, the limiting and inducible enzyme of the prostaglandins biosynthesis pathway, takes part in senescence of NHDFs (Zdanov et al. Exp Cell Res 2007). We therefore further investigated how this pathway induces senescence. We have shown that PGE2, the main prostaglandin produced by COX-2, is able to induce both the onset and the maintenance of senescence. It did so only when imported inside the cell by the PGE2/lactate transporter, indicating that PGE2 acts on senescence more via the pool of intracellular EP receptors than via those localized at the cell surface. Treatment with agonists, antagonists and silencing of the EP receptors by siRNA revealed that, among EPs, EP3 was the most involved in transducing the intracrine effects of PGE2 (Pluquet et al. BBA Lipids 2013).

A.6- Senescence is associated with Endoplasmic Reticulum stress and activation of the Unfolded Protein Response
Since the endoplasmic reticulum (ER) is the first organelle in the secretory pathway, we hypothesized that the changes in the SASP could be the consequence of an ER stress occurring at senescence. We showed that NHDFs exhibit an ER expansion associated with a mild and chronic activation of the Unfolded Protein Response (UPR) pathway. We investigated more precisely the activation of the three arms of the UPR, PERK, IRE1 and ATF6a, which contribute to re-establish the reticulum homeostasis through specific effectors. We showed that inhibiting the ATF6a pathway, and only this pathway, partly abolished some senescence markers, including the increase in some components of the SASP (Druelle et al, Oncotarget, 2016).
We then postulated that the UPR could operate in senescence through the above described COX-2 pathway, because most of the enzymes and receptors of this pathway are associated to the ER membrane. The inhibition of ATF6a by siRNA in pre-senescent NHDFs, but not of PERK or IRE1, induced a decrease in COX-2 and PGES1 and 2 expressions as well as a decrease in PGE2 production. Correlatively, it partially delayed the occurrence of senescence markers, including some SASP components. These effects were prevented by favoring the import of PGE2, but not just by supplying extracellular PGE2. Conversely, treating young NHDFs by ER stress inducers such as dithiothreitol induced premature senescence accompanied by COX-2 overexpression and PGE2 production. Inhibiting COX-2 activity by NS398 partially blocks the dithiotreitol-induced premature senescent phenotype. Taken together, these results indicate that ER stress is an inducer of senescence, operating, at least in part, through an ATF6a/COX-2/PGE2/intracellular EP3 pathway (Cormenier et al, Mechanisms of Ageing and Development, 2018. The roles of ER stress and UPR activation at senescence was reviewed in Pluquet et al, Am J Physiol Cell Physiol, 2015.

B- mechanisms of action of the HIC1 tumor suppressor, and O-GlcNAcylation as a post-translational modification activated in response to metabolic stress
B.1- Role of HIC1 in the DDR.
The tumor suppressor HIC1 (Hypermethylated in Cancer1) is epigenetically silenced by hypermethylation of its promoter -hence its name- in many tumors, but is not mutated. HIC1 encodes a transcriptionnal repressor associating a BTB/POZ domain to Krüppel C2H2 Zinc fingers mediating its sequence specific DNA-binding to promoters of target genes. The HIC1 protein is involved in complex regulatory loops with P53 and the deacetylase SIRT1.
We have first characterized the HIC-1 specific DNA-binding sequence, some of its target genes as well as many partners involved in repression complexes (Pinte et al, 2004; Dehennaut et al, Biochem Biophys Res Commun, 2013; Dubuissez et al, Biochem Biophys Res Commun, 2013). We have also identified some HIC1 post-translational modifications (PTMs) notably an Acetylation/SUMOylation switch on Lysine 314 (K314) which modulates the interaction between HIC1 and MTA1, a core component of NuRD complexes (Stankovic-Valentin et al, Mol Cell Biol, 2007; Van rechem et al, Mol Cell Biol, 2010). HIC1 favors the p53-dependent apoptotic response to irreparable DNA double strand breaks (DSBs) induced by Etoposide through direct transcriptional repression of SIRT1 (Dehennaut et al, J Biol Chem, 2013). We have in part deciphered and clarified the molecular mechanism. Indeed, we have demonstrated that upon induction of irreparable DNA double-strand breaks (DSBs), HIC1 SUMOylation increased, thereby favoring the recruitment of MTA1 on the promoters of HIC1 target genes and notably on SIRT1 (Paget et al., Oncotarget, 2017).
In addition to its role as a “classical” transcriptional repressor in the case of irreparable DSBs, we have shown that HIC1 is also involved in the repair process when cells are treated for a short period (1 hour) with Etoposide, a treatment which induces repairable breaks. We have shown using Comet assays that human BJ-Tert fibroblasts inactivated for HIC1 through RNA interference repair after 16 hours the damage as efficiently as cells transfected with a control siRNA, but with a strikingly delayed kinetics notably in the early steps (4-6 hours after the induction of DSBs) (Paget et al., Oncotarget, 2017).
During the induction of repairable DNA damages, we have shown that HIC1 SUMOylation is not required for the repair process since a non-SUMOylatable, but still acetylable, E316A point mutant is as efficient as the WT HIC1 as shown by Comet assays. We have therefore hypothesized that other HIC1 PTMs could be essential for its role in the repair process. Through a combination of in silico and mass-spectrometry analyses, we have demonstrated that in the case of repairable damages, HIC1 is directly phosphorylated on a Serine residue by ATM, one of the apical PIKK kinases involved in the DNA-damage response. This phosphorylation site is phylogenetically conserved and is localized in the C-terminal region of HIC1, for which no molecular function had been assigned so far despite its high level of phylogenetic conservation. This phosphorylation site is essential for HIC1’s function in DSBs repair since a non-phosphorylable (S to A) point mutation severely delays the execution of DNA repair as shown by Comet assays. We have obtained a phospho-specific antibody. With this antibody, we have shown that HIC1 phosphorylation is rapid and detectable 10 minutes after the Etoposide treatment. This phosphorylation has no impact on the SUMOylation of HIC1 thus confirming that these two PTMs are not connected but are involved in two different DNA damage response pathways to repairable and irreparable DSBs respectively. This phosphorylation of HIC1 does not modify its global subcellular localization since the S to A point mutant is also nuclear in immunofluorescence analyses of transfected HEK293 cells. However, in cell fractionation experiments of BJ-tert fibroblasts treated for 1 hour with Etoposide, we observed that all the phosphorylated endogenous HIC1 proteins are excluded from the chromatin fraction and are localized in the cytoplasmic/nucleoplasmic fraction (in preparation). This is highly reminiscent of the situation described for the KAP1 co-repressor that we used as a positive control in our fractionation experiments. In fact, KAP1 which is involved in the repression of heterochromatin is excluded from heterochromatin after its phosphorylation by ATM. This “opening” of heterochromatin is required to facilitate the repair of DSBs occurring in the dense heterochromatin which is less accessible than the loosely packed euchromatin (Ziv et al, Nature cell Biol, 2006; Goodarzi and Jeggo, Advances in genetics, 2013).
Analyses by qRT-PCR of genes involved in the “Human DNA Damage Signaling pathway” (RT-Profiler, Quiagen) using RNAs prepared from WPMY myofibroblasts transfected with a control siRNA or with siRNAs targeting HIC1 and then treated with Etoposide for 1 hour, demonstrated that HIC1 in that case is involved in the repression of some target genes notably two P53-target genes, the cell cycle inhibitor CDKN1A (p21) and the pro-apototic protein PUMA (P53 Up regulated Modulator of Apoptosis). We are pursuing these experiments in collaboration with Drs G Boulay and MN Rivera, (MGH, Boston, USA) by global RNA-Seq of BJ-tert fibroblasts transfected with a control siRNA or with siRNAs targeting HIC1 and then treated with Etoposide for 1 hour and by Chip-Seq experiments of BJ-tert fibroblasts treated or not with Etoposide for 1 hour to have access to genes repressed by HIC1 and to define its genome-wide binding sites in eu- and heterochromatin, with the hope to validate our putative model.
In conclusion, HIC1 could be a multifaceted player in the DNA damage response with strikingly different roles depending on the nature of the DNA damage received by the cells, either irreparable DSBs which trigger an apoptotic response or repairable damages which should be repaired faithfully by the cells. In the case of irreparable damages, HIC1 would be a classical transcriptional repressor which, through its SUMOylation and the increased interaction with NuRD complex, could favor the P53-dependent apoptotic response. In the case of repairable damages, HIC1 could be a transcriptional repressor but tuning down some P53 target genes to allow cell–cycle re-entry when the DSBs have been repaired. In addition, HIC1 could be excluded from heterochromatin to facilitate the access of the repair machinery to this otherwise densely packed DNA to allow its repair.

B.2- O-GlcNAcylation as a new link between nutrition, epigenetics and colorectal cancer.
Colorectal cancer (CRC) is one of the leading causes of mortality and morbidity by cancer – the second for women and the third for men – and is often associated with metabolic disorders (obesity, diabetes…). Largely spread in the Western societies, these two groups of pathologies are tightly linked. It is now widely accepted that the occurrence of CRC is dependent on the interplay between the genome and the epigenome, which together interact with environmental factors, including nutrition.
O-GlcNAcylation is a post-translational modification (PTM) belonging to the large group of glycosylations. Unlike to the other types of glycosylation, protein O-GlcNAcylation is confined within the cytosolic, nuclear and mitochondrial compartments. O-GlcNAcylation is highly dynamic like phosphorylation with which it can either act in concert or conversely compete for the same or the adjacent serine/threonine residues. The addition and the removal of the GlcNAc residue is mediated by the O-GlcNAc transferase (OGT), using the nutrient-sensor UDP-GlcNAc as the sugar donor, and the O-GlcNAcase (OGA) respectively. The level of UDP-GlcNAc, supplied by the hexosamine biosynthetic pathway (HBP), tightly correlates to the cell nutrient status since many metabolic pathways are required for the biosynthesis of the nucleotide-sugar. Accordingly, due to its crucial position, it has been suggested that O-GlcNAcylation regulates cell metabolism and functions in a nutrient-dependent manner. So we hypothesized that O-GlcNAcylation could relay the effects of an excessive food supply, malnutrition, obesity, and other metabolic problems that represent high risk factors of CRC.
In this sense, in a precedent set of studies, we observed increased contents of O-GlcNAcylation and OGT in human colon cancer samples in comparison with normal tissues (Olivier-Van Stichelen*, Dehennaut* et al., 2014). Contrary, we reported that silencing OGT diminished in vitro proliferation, cell survival and adhesion of colon cancer cell lines (Steenackers et al., 2016) thus defining aberrant OGT and O-GlcNAcylation levels as new CRC hallmarks.
Regarding the underlying mechanisms linking aberrant O-GlcNAcylation to CRC, we demonstrated that O-GlcNAcylation stabilizes β-catenin, the key regulator of the Wnt signaling pathway and whose aberrant stabilization is found in 90% of CRCs, through direct competition with phosphorylation at Thr41 (Olivier-Van Stichelen*, Dehennaut* et al., 2014). In this context, we also showed that colons from mice fed by high-carbohydrate diets exhibited higher amounts of O-GlcNAcylation and of -catenin relative to mice fed a standard diet (Olivier-Van Stichelen*, Dehennaut* et al., 2014). These results thus sustain the hypothesis that nutritional disorders, even of short duration, are able to disrupt the dynamic of O-GlcNAcylation leading to the modulation of the expression of an oncogene, without any mutation, that could predispose to the emergence of CRCs.
Currently, we are focusing on the regulation of the expression of the members of the UNC5 gene family by O-GlcNAcylation. The UNC5 gene family consists of four related genes: UNC5A, UNC5B, UNC5C and UNC5D that act as receptors of Netrin-1. These genes belong to the family of dependence receptors that share the ability to regulate apoptosis positively or negatively, respectively in the absence or presence of their ligand and thus are defined as conditional tumor suppressors. The expression of some of these genes is frequently down-regulated in colorectal cancer (CRC) in part through epigenetic mechanisms not fully understood. In recent years, O-GlcNAc transferase (OGT) has emerged as an important regulator of chromatin dynamic and gene expression notably by regulating the function of the histone methyltransferase EZH2, the catalytic subunit of the Polycomb Repressive Complex 2 (PRC2) (Dehennaut el al., 2014). In this context, we hypothesized that the OGT-EZH2 axis could play a role in the epigenetic downregulation of the UNC5 gene family in CRC. First, we observed that the knockdown of OGT by RNAi in the colon cancer cell line HCT116 leads to an increase of UNC5A mRNAs but has no effect on the expression of the other members of the UNC5 family. By a combination of pharmalogical inhibitions and RNA interference approaches coupled to RT-qPCR analyses and promoter activities studies, we demonstrated that OGT/O-GlcNAcylation and EZH2 were both involved in the repression of UNC5A transcription in colon cancer cells. By lectin enrichment experiments, we confirmed the O-GlcNAcylation of EZH2 in HCT116 cells. Overexpression of the core PRC2 complex in these cells reduces UNC5A expression but inhibiting OGT activity with Ac5S-GlcNAc alleviates this PRC2-mediated repression of UNC5A. Taken together, these data demonstrate that the O-GlcNAcylated form of EZH2 represses the transcription of UNC5A and further support the hypothesis that hyper-O-GlcNAcylation could contribute to aberrant EZH2 activity leading to the repression of key tumor suppressor genes governing the cancerization of the colonic mucosa.

C- Non-coding RNAs in cancer and during fibrogenesis
C.1- Understanding the role of miRNAs during fibrogenesis.
Fibrosis is the final common pathway in virtually all forms of chronic organ failure, including lung, liver, and kidney, and is a leading cause of morbidity and mortality worldwide. Fibrosis results from the excessive activity of fibroblasts, in particular a differentiated form known as myofibroblast that is responsible for the excessive and persistent accumulation of scar tissue and ultimately organ failure. As mechanistic studies have linked ncRNAs to a broad spectrum of complex human disorders, ncRNA-based therapies offer new tremendous opportunities to treat incurable diseases. In line with this, we reasoned that ncRNAs play a substantial role in the pathogenic events leading to fibrogenesis and therefore may represent new diagnostic/prognostic biomarkers as well as new valuable druggable targets.
The process of fibrogenesis (renal, pulmonary and hepatic) has been so far apprehended in several pathological contexts (IgA nephropathy, chronic immunosuppressor use, exposure to heavy metals, Idiopathic Pulmonary Fibrosis), using cellular models (epithelial and fibroblast cell lines, primary cultures of epithelial cells), mouse models (unilateral ureteral obstruction, renal ischemia-reperfusion, osmotic pumps delivering immunosuppressors, pulmonary fibrosis induction by instillation of bleomycin liver fibrosis induction by bile duct ligation or CCl4 injections…) and cohorts of patients. High throughput transcriptomic analyses allowed us to show that some miRNAs are commonly involved in the development of pulmonary, renal and hepatic fibrosis.
a / In particular, we characterized the involvement of three miRNAs (miR-199a-5p (filled patent), miR-199a-3p and miR-214-3p) generated from the same locus, LncRNA DNM3OS, a long non-coding RNA, (Lino Cardenas et al., 2013, Savary et al., 2019). The miRNAs of this cluster participate in the activation of fibroblasts and their differentiation into myofibroblasts via the regulation of TGFβ canonical and non-canonical pathways, targeting in particular CAV1 (miR-199a-5p) and GS3Kβ (miR-214-3p). We also showed that DNM3OS is also involved in epithelial repair mechanisms by regulating KGF and HGF factors (miR-199a-3p). Finally, we showed that interfering with DNM3OS function using distinct pharmacological strategies (anti-miR, Target Site Blocker and gapmer) not only prevents lung, liver and kidney fibrosis, but also improves established lung fibrosis, providing thus a novel paradigm for the treatment of fibrotic diseases (Savary et al., 2019).
b / Furthermore, we confirmed the role of miR-21 in the renal fibrosis process (Glowacki et al., 2013, Hennino et al., 2016) and then proposed the interest of this miRNA as a non-invasive biomarker of renal fibrosis, serum levels of miR-21 being correlated with the severity of renal fibrosis lesions (Glowacki et al., 2013). The prominent role of miR-21 has also been evaluated in the context of chemical-induced nephrotoxicity, in particular Cadmium (Lemaire et al., 2020) and chronic use of calcineurin inhibitor (Vandenbussche et al., 2018).
C.2- Identifying new molecular determinants underlying cisplatin response in term of efficacy and nephrotoxicity
Cisplatin, a widely used first line chemotherapeutic drug for various cancers, has attracted intense research attention since it was introduced to the market over 40 years ago. Although cisplatin effectively shrinks the tumor, its nonspecific accumulation in both tumor and normal tissues has also caused severe side effects such as nephrotoxicity. Therefore, intensive research efforts are devoted towards enhancing cisplatin antitumoral efficacy while improving its safety profile. In this context, we developed two projects one related to uncover new molecular determinants mediating cisplatin resistance in lung cancer and the other related to the prevention of cisplatin-induced nephrotoxicity.
2.a: Identification of new molecular determinants underlying cisplatin resistance. We performed a functional miRNA library screening to identify miRNAs associated with resistance to cisplatin. The screening performed with about 1000 mimics revealed that overexpression of miR-24-3p, a miRNA identified as the best hit, reproducibly induces cisplatin resistance of A549 lung cancer cells. Finally, we were able to demonstrate through multiple independent in vitro approaches that miR-24-3p is a potent regulator of not only cisplatin-induced lung cell death, but also response to EGFR-targeted therapies (filled patent).

2.b: Identification of new molecular determinants underlying cisplatin nephrotoxicity. In an effort to uncover new pharmacological approaches preventing cisplatin nephrotoxic effects, we aimed to test two potential strategies. We first hypothesized that inhibiting miR-21, which is mainly involved in cell injury (see paragraph 1), could diminish renal cisplatin injury. Using a mouse model, our first results have indicated that miR-21 plays an ambivalent role in renal lesions and seems to be protective at an early stage, or deleterious when the process is prolonged over time. We have also demonstrated that interfering with Adenosine Receptor A2A (A2AR) signalling attenuates cisplatin-induced nephrotoxicity without compromising its cytotoxic effectiveness (patent deposited). In addition, we initiated a prospective study aiming at uncovering new clinical parameters correlated to cisplatin-induced nephrotoxicity (collaboration with the Department of Thoracic Oncology, CHRU, Lille).
