Team : Efficacy & Resistance to anti-tumor targeted Therapies

NEWS

A mushroom to the aid of patients with rare genetic diseases.

This last decade, emergence of targeted therapies profoundly changed the care of some patients displaying oncogene addiction, with improvement of their live condition or expectancy. However, all the targeted therapies have to face to emergence of resistances, leading to inevitable treatment failures. In addition, many cancers are still diagnosed at a metastatic stage, a step of the disease that escapes to treatment efficacy and still associated with a poor prognosis due to an altered response to treatment.

The global aim of our research project is to decipher the molecular mechanisms leading to oncogene addiction and later to resistance process in order to improve treatment with targeted therapies.

We are focusing our attention on the lung and prostate cancers, including their metastatic progression, representing together the main causes of lethality by cancer. For both lung and prostate cancers, we take advantage on our expertise on well-documented oncogenes deregulated in these cancers including receptor tyrosine kinase (RTK) and ETS-Fusion genes. We are also developing new therapeutic approaches to correct nonsense mutations that represent 5 to 40% of the mutations affecting the tumor suppressor genes and responsible for also about 10% of any genetic diseases.

We deliberately chosen to work in strong collaboration with molecular biologists, pathologists, and clinicians of the Lille university hospital who are directly involved in patient care.

MET deregulation in lung cancer

Lung tumor expressing MET receptor at the invasion front

Dysregulation of the RTKs is often a key step in carcinogenesis and thus represent a major target for therapeutic interventions. Targeted therapies have already demonstrated efficacy in various cancers, as in EGFR-mutated non-small cell lung cancer (NSCLC). Identification of alterations in RTKs amenable to chemical inhibition is still a major field of research as illustrated by the recent finding that mutations affecting exon14 splice sites of the MET receptor confer sensitivity to MET inhibitors. Therefore, the current challenges are: (i) to understand the consequences of RTK deregulation in cancer, which could improve the selection of eligible patients (ii) to improve diagnosis of RTK alterations and (iii) to anticipate the resistance mechanisms to propose alternative strategies. To face these challenges, we developed these last five years an integrated approach with strong collaborations with pathologists, molecular biologists and oncologists of Lille university hospital.

Moving to the more recently described MET exon14 splice sites mutations, which represent a new and poorly known type of alteration amenable to targeted therapies, we aimed first at providing a better insight into the biology and functional consequences of these mutations. Because MET exon14 mutations lead to deletion of its juxtamembrane domain, we searched to decipher regulation mechanisms associated to this domain. We demonstrated that the juxtamembrane domain of MET is subjected to several proteolytic cleavages directly affecting its activity. MET is notably cleaved by caspases during apoptosis leading to generation of an active fragment (p40MET) able to favor cell death through permeabilization of mitochondria (Lefebvre et al., Cell Death Dis, 2013). Physiological relevance of such cleavages was demonstrated by engineering knock-in mice harboring mutation of the MET caspase site (MET caspase), in which we demonstrated involvement of MET cleavage in liver apoptosis (Duplaquet et al, eLife 2020). In the same line, we demonstrated that juxtamembrane domain is also targeted by gamma-secretase or calpain proteases all involved in MET degradation through generation of labile fragments (Montagne et al., Oncotarget, 2017; Copin et al., Lung Cancer, 2016; Montagne et al., Cell Death Dis, 2015). Taken together, this set of results demonstrates that the loss of the MET juxtamembrane domain observed in lung cancer potentially regulate positively MET activity through decrease of its degradation and inhibition of its pro-apoptotic function, thus reinforcing the rationale for targeting these alterations. Involvement of MET in tumorigenesis including MET exon14 mutations was reviewed in Duplaquet et al., Oncogene, 2018; Cortot et al., JNCI ,2017; Furlan et al., Cancer Res. 2014; Furlan et al., Hepatology, 2013.

Improvement of RTK alteration detection

Detection of MET exon 14 mutations in NSCLC patients

Detection of MET exon14 splice sites mutations is challenging because of their localization in introns and high heterogeneity. Thus, thanks to a close collaboration with the diagnosis molecular labs, the pathology department and the thoracic oncology department of Lille university hospital, we designed an optimized targeted next generation sequencing (NGS) panel able to detect MET alterations in addition to the main molecular targets usually covered. This NGS panel, now used in routine practice, allowed raising the rate of detection of MET mutations from 0.3% to 2.2% of NSCLC patients (Descarpentries et al., J Thorac Oncol, 2018, Baldacci et al., J Thorac Oncol, 2020). Patients identified as harboring MET exon 14 mutations will likely benefit from MET-TKIs, either as part of clinical trials such as the VISION trial (Merck Serrono) or as part of an off-label use of available MET-TKIs.

In a more comprehensive view, we extended research of RTK alterations to the whole RTK family. We focus our attention on the metastatic colorectal cancer, in which RTK alterations were poorly described. Valuable couples of tumor and metastatic samples were collected in north of France hospitals with the help of the “Canceropole Nord-Ouest”. Although high throughput NGS revealed multiple original RTK mutations, systematic functional analysis showed that none of them are activating-mutations. This highlights the importance of functional studies to validate RTK mutations as potential therapeutic target (Duplaquet et al, Mol Cancer Ther, 2019).

Involvement of MET receptor in resistance

In addition to its involvement as an initial oncogene driver, MET is also a resistance factor able to shortcut inhibition of other RTKs. Since resistance emergences are associated to therapeutic failures, their understanding and anticipation are crucial. Therefore, we attended to decipher the role of MET dysregulation in resistance to EGFR-TKIs in EGFR-mutated NSCLC. First, we addressed the question of the functional consequences of MET amplification on the phenotype of EGFR-mutated NSCLC. Using cell lines and mouse models, we found that MET amplification is not only a way to bypass EGFR signaling and confer resistance to EGFR-TKIs, but it also provides new and aggressive properties to the tumor and promotes metastasis through the PEA3 subgroup of ETS transcription factors. (Kherrouche et al., Mol Oncol. 2015; Baldacci, Kherrouche et al., Lung Cancer, 2018). As a clinical counterpart of these results, we demonstrated based on a national collection of all known cases, that EGFR-mutated NSCLC patients harboring MET amplification display a shorter time to new metastasis than others (Baldacci et al., Oncotarget, 2017).

Furthermore, MET TKIs have demonstrated efficacy against advanced NSCLC with mutations causing MET exon 14 skipping (METex14 mutations), but primary resistance seems frequent, as response rates are lower than for targeted TKIs of other oncogene-addicted NSCLC. Using notably cell lines derived from patients with primary resistance to a MET, we demonstrated that PI3K-pathway alteration (including PI3K activating mutations and PTEN deletion) is a common mechanism of resistance to MET TKI. Interestingly, in preclinical models, PI3K inhibition restores sensitivity to MET TKIs, opening the way for treatment strategy to overcome resistance (Jamme et al, J Thorac Oncol, 2020).

Correction of nonsense mutations in cancers and other genetic diseases

Colocalization in cytoplasmic foci in HeLa cells of UPF1 (green) and DCP1a (red) upon colchicine treatment

Nonsense mutations change a codon into a premature termination codon. The consequence of the presence of a premature termination codon is the absence of expression of the gene due to the activation of a quality control mechanism named nonsense-mediated mRNA decay (NMD). Approximatively 10% of patients with a genetic disease are due to a premature termination codon. Genetic diseases include rare diseases such as cystic fibrosis, Duchenne muscular dystrophy, Rett syndrome, etc… and also frequent pathologies like metabolic or neurologic disorders and cancers.

In the lab, we search for molecules capable of rescuing the functional expression of genes carrying a nonsense mutation. For that we developed screening systems to identify molecules that inhibit NMD and/or activate PTC-readthrough (Gonzales et al., Orphanet Journal of Rare diseases 2012, Benhabiles et al., Plos One 2017, Trzaska et al., Nature Commun 2020). Screen selected molecules are then tested on cell and mouse models carrying a nonsense mutation in TP53, PTEN, CFTR or dystrophin gene in order to characterize the molecules and understand how they work. We aim to develop new therapeutic approaches for genetic diseases caused by nonsense mutations and to improve our knowledge on the mechanisms recognizing premature termination codons and their regulation. Past studies from our lab demonstrated that NMD is inhibited during apoptosis due to caspase cleavages of two main NMD factors named UPF1 and UPF2 (Jia et al., Cell Death and Diff, 2015).

We also found that cytoskeleton disruptors are strong NMD inhibitors. The study of these molecules lead us to identify and characterize new cytoplasmic foci in which PTC readthrough occurs and that we named readthrough bodies (Jia et al., J Cell Science, 2017).

Bone metastasis and ETS transcription factor in prostate cancer

Bone metastasis in animal models of prostatic cell lines expressing or not ERG fusion

Prostate cancer (PCa) is one of the most commonly diagnosed diseases and the second cause of cancer-related deaths affecting men in the Western world. PCa shows a strong propensity to metastasize to bone, promoting osteoblastic or mixed blastic/lytic lesions in more than 80% of advanced stage PCa patients. This leads to major injurious events such as severe pain, nerve compression and pathologic fracture. PCa that has metastasized to bone remains incurable and is more likely to lead to a fatal outcome than a primary tumor alone.

The discovery of gene fusions resulting from chromosomal rearrangements leading to the aberrant and androgen-regulated expression of the ETS family transcription factors in 50 to 80% of PCa cases is a major breakthrough which challenges the current understandings of the pathology. A major challenge for PCa treatment is to identify factors controlling tumor growth and metastases as well as markers to follow the progression of PCa from diagnosis to the apparition of metastases. Our objective was to study whether the ETS fusion genes, which are the most frequent gene rearrangements identified in PCa, are involved in bone metastasis formation.

As a first step, we used PCa cell lines to overexpress the ETS fusions (ERG and ETV1) and studied their effect in vitro. The ERG fusion is the most frequent in PCa. Interestingly, its ectopic expression increased the migration and invasion properties of tumor cells by deregulating target genes such as MMP9, which is an extracellular metalloprotease known to be involved in tumor invasion mechanisms (Tian et al., Oncogene, 2014).

Next, we used an in vivo model using intra-cardiac injections in mice to demonstrate that the expression of the ERG fusion increases the number of metastatic lesions in the bone. We also found that this fusion affects the pattern of metastatic spread by increasing the incidence of lesions in hind limbs and spine, which also happen to be two of the most frequent sites of human PCa metastases (Deplus et al., Oncotarget, 2017).

In addition, using a second in vivo model in which we injected tumor cells directly in the bone microenvironment (tibiae) of SCID mice, we found that the human PCa cells which stably overexpress the ERG fusions, increase the osteoblastic phenotype of bone lesions and inhibit the bone osteoclastic destruction (Delliaux, Tian et al., Cancer letters, 2018).

Based on those results, we performed transcriptomic analyses and identified a series of fusion-driven genes associated with bone tropism and metastasis formation. Indeed, osteotropic PCa cells are believed to acquire bone cell-like properties, which improve their homing, adhesion, proliferation and survival in the bone microenvironment. Interestingly, we demonstrated that the ERG fusion protein increases and directly regulates the expression of at least two major osteoblastic markers: type I Collagen and Alkaline phosphatase. We also demonstrated that the ERG fusion enhances the expression of Endothelin-1, which is a protein with a documented role in osteoblastic bone lesion formation.

Furthermore, in addition to these genes involved in osteomimicry, we identified new ERG target genes that were until recently unknown in PCa, such as Plexin-A2 and their coreceptors and ligands, belonging to the axon guidance gene family. We showed that their silencing modifies the migration and invasion properties of tumor cells, suggesting a potential role in tumor progression.

Besides, since extracellular vesicules such as exosomes have recently been shown to play a crucial role in tumor cell organotropism, we started to characterize the exosomes secreted by tumor cells expressing the ETS fusions in order to understand their role in bone tropism. Our preliminary results show that proteins corresponding to some of ERG target genes, are detected in exosomes, and therefore, as described in recent publications, may contribute to bone metastasis niche formation.

At the same time, thanks to our close collaboration with the hospital oncologists and anatomo-pathologists (CHRU, Centre Oscar Lambret, CHRU-tissue bank), we ascertained the clinical relevance of the identified genes by correlating for instance expression of MMP9, Plexin-A2 or Endothelin-1 with metastasis fusion-positive samples of human PCa. This translational research may lead to the identification of some of the candidate genes as new markers or therapeutic targets.

In addition, we investigated the role of ETS transcription factors in tumorigenesis and metastasis in breast cancer (BrCa), which is another hormone-regulated cancer associated to frequent bone metastasis. We showed that among the molecular events downstream of the ETS transcription factor ETV4, MMP13 (an extracellular metalloprotease) is a direct target gene and participates to ETV4-induced tumor formation in immunodeficient mice by disturbing cell proliferation, migration and invasion. Finally, ETV4 and MMP13 co-overexpression is associated to poor prognosis in BrCa (Dumortier et al., Breast Cancer Res., 2018). Interestingly, MMP13 has been shown to play a direct role in dissolving bone matrix complementing the activity of MMP9 and other enzymes, and to be involved in BrCa bone osteolytic lesions.

Altogether, our results shed light on an unprecedented role for one of the ETS fusions, the ERG fusion, in the increase of both bone tropism and osteoblastic lesion formation induced by PCa cells. Particularly, we identified ERG fusion target genes, such as Plexin-A2, Neuropilins and semaphorins which belong to the axon guidance gene family. Their study opens a new avenue to understand the molecular mechanisms that lead to the formation of bone metastases in PCa.

Finally, our objective is to establish a gene signature expressed by tumor cells or exosomes in order to design a novel tool for the diagnosis of cancer progression, and more specifically bone metastasis, and thus to improve assessment, treatment and management of patients with PCa.
