Abstract
Renal cell carcinoma (RCC) represents around 2% of cancer-related deaths worldwide per year. RCC is an immunogenic malignancy, and treatment of metastatic RCC (mRCC) has greatly improved since the advent of the new immunotherapy agents, including immune checkpoint inhibitors (ICIs). However, it should be stressed that a large proportion of patients does not respond to these therapies. There is thus an urgent need to identify predictive biomarkers of efficacy or resistance associated with ICIs or ICI/Tyrosine kinase inhibitor (TKI) combinations; this is a major challenge to achieve precision medicine for mRCC in routine practice. To identify potential biomarkers, it is necessary to improve our knowledge on the biology of immune checkpoints. A lot of efforts have been made over the last decade in the field of immuno-oncology. We summarize here the main data obtained in this field when considering mRCC. As for clinical biomarkers, clinician and scientific experts of the domain are facing difficulties in identifying such molecular entities, probably due to the complexity of immuno-oncology and the constant adaptation of tumor cells to their changing environment.

Abstract
Background Despite the significant advances in the management of advanced prostate cancer (PCa), metastatic PCa is currently considered incurable. For further investigations in precision treatment, the development of preclinical models representing the complex prostate tumor heterogeneity are mandatory. Accordingly, we aimed to establish a resource of patient-derived xenograft (PDX) models that exemplify each phase of this multistage disease for accurate and rapid evaluation of candidate therapies. Methods Fresh tumor samples along with normal corresponding tissues were obtained directly from patients at surgery. To ensure that the established models reproduce the main features of patient's tumor, both PDX tumors at multiple passages and patient's primary tumors, were processed for histological characteristics. STR profile analyses were also performed to confirm patient identity. Finally, the responses of the PDX models to androgen deprivation, PARP inhibitors and chemotherapy were also evaluated. Results In this study, we described the development and characterization of 5 new PDX models of PCa. Within this collection, hormone-naïve, androgen-sensitive and castration-resistant (CRPC) primary tumors as well as prostate carcinoma with neuroendocrine differentiation (CRPC-NE) were represented. Interestingly, the comprehensive genomic characterization of the models identified recurrent cancer driver alterations in androgen signaling, DNA repair and PI3K, among others. Results were supported by expression patterns highlighting new potential targets among gene drivers and the metabolic pathway. In addition, in vivo results showed heterogeneity of response to androgen deprivation and chemotherapy, like the responses of patients to these treatments. Importantly, the neuroendocrine model has been shown to be responsive to PARP inhibitor. Conclusion We have developed a biobank of 5 PDX models from hormone-naïve, androgen-sensitive to CRPC primary tumors and CRPC-NE. Increased copy-number alterations and accumulation of mutations within cancer driver genes as well as the metabolism shift are consistent with the increased resistance mechanisms to treatment. The pharmacological characterization suggested that the CRPC-NE could benefit from the PARP inhibitor treatment. Given the difficulties in developing such models, this relevant panel of PDX models of PCa will provide the scientific community with an additional resource for the further development of PDAC research.

Abstract
Renal-cell carcinoma (RCC) accounts for 2% of cancer diagnoses and deaths worldwide. Clear-cell RCCs represent the vast majority (85%) of kidney cancers and are considered morphologically and genetically as immunogenic tumors. Indeed, the RCC tumoral microenvironment comprises T cells and myeloid cells in an immunosuppressive state, providing an opportunity to restore their activity through immunotherapy. Standard first-line systemic treatment for metastatic patients includes immune-checkpoint inhibitors (ICIs) targeting PD1, in combination with either another ICI or with antiangiogenic targeted therapy. During the past few years, several combinations have been approved with an overall survival benefit and overall response rate that depend on the combination. Interestingly, some patients achieve prolonged complete responses, raising the question of whether these metastatic RCC patients can be cured. This review will focus on recent therapeutic advances in RCC and the clinical and biological aspects underpinning the potential for healing.

Abstract
Background Muscle-invasive bladder cancer (MIBC) and upper urinary tract urothelial carcinoma (UTUC) are molecularly heterogeneous. Despite chemotherapies, immunotherapies, or anti-fibroblast growth factor receptor (FGFR) treatments, these tumors are still of a poor outcome. Our objective was to develop a bank of patient-derived xenografts (PDXs) recapitulating the molecular heterogeneity of MIBC and UTUC, to facilitate the preclinical identification of therapies. Methods Fresh tumors were obtained from patients and subcutaneously engrafted into immune-compromised mice. Patient tumors and matched PDXs were compared regarding histopathology, transcriptomic (microarrays), and genomic profiles [targeted Next-Generation Sequencing (NGS)]. Several PDXs were treated with chemotherapy (cisplatin/gemcitabine) or targeted therapies [FGFR and epidermal growth factor (EGFR) inhibitors]. Results A total of 31 PDXs were established from 1 non-MIBC, 25 MIBC, and 5 upper urinary tract tumors, including 28 urothelial (UC) and 3 squamous cell carcinomas (SCCs). Integrated genomic and transcriptomic profiling identified the PDXs of three different consensus molecular subtypes [basal/squamous (Ba/Sq), luminal papillary, and luminal unstable] and included FGFR3-mutated PDXs. High histological and genomic concordance was found between matched patient tumor/PDX. Discordance in molecular subtypes, such as a Ba/Sq patient tumor giving rise to a luminal papillary PDX, was observed (n=5) at molecular and histological levels. Ten models were treated with cisplatin-based chemotherapy, and we did not observe any association between subtypes and the response. Of the three Ba/Sq models treated with anti-EGFR therapy, two models were sensitive, and one model, of the sarcomatoid variant, was resistant. The treatment of three FGFR3-mutant PDXs with combined FGFR/EGFR inhibitors was more efficient than anti-FGFR3 treatment alone. Conclusions We developed preclinical PDX models that recapitulate the molecular heterogeneity of MIBCs and UTUC, including actionable mutations, which will represent an essential tool in therapy development. The pharmacological characterization of the PDXs suggested that the upper urinary tract and MIBCs, not only UC but also SCC, with similar molecular characteristics could benefit from the same treatments including anti-FGFR for FGFR3-mutated tumors and anti-EGFR for basal ones and showed a benefit for combined FGFR/EGFR inhibition in FGFR3-mutant PDXs, compared to FGFR inhibition alone.

Abstract
Abstract
Prostate Cancer (PCa) is the second most frequent cancer in men worldwide and the fifth leading cause of cancer death with an incidence rate of 13.5%. PCa is driven by multiple genomic alterations, with distinct patterns and clinical implications. These genomic alterations occurring both early and later in the natural history of the disease (ranging from localized disease, initially responsive to androgen deprivation therapy, to Castrate Resistant Prostate Cancers -CRPC) allow classification of PCa in several molecular subtypes with potential clinical relevance. Patient-Derived Xenograft (PDX) models have become the most reliable in vivo human cancer models. Developing such models that capture the biological heterogeneity and mutational landscape of PCa, remains a challenge, but is essential for delivery of precision medicine in metastatic castrate resistant stages. In this study, we present the genomic and transcriptomic landscapes, as well as the pharmacological status of an established bank of seven (7) prostate PDX models ranging from hormone naïve to hormone-resistance PCa specimens. Samples of PCa along with normal corresponding tissues were obtained directly from patients at surgery. Fragments were subcutaneously xenografted into immunocompromised mice to establish PDX models. After the first growth in mice, they were serially passaged in vivo and considered to be established from P3. To ensure model stability, PDX tumors at multiple passages and patients' primary tumors were processed for histological, transcriptomic (Affymetrix U133 plus 2.0 microarray) and STR profile analyses. Genomic characteristics (WES, CNA) were also investigated. Finally, the responses of the PDX models to androgen deprivation and docetaxel were also evaluated. 7 PDX models were successfully established (> P3 in mice) out of 253 primary prostatic tumors collected from surgery. Within those models, one matched pair of responsive adenocarcinoma and neuroendocrine castration-resistant (NE-CRPC) models from the same patient was generated. Histological, transcriptomic and STR profiling validated the stability of the models compared to the parental tumor. The genomic analyses revealed i) the mutational burden rise with the resistance to treatments of the models, correlating with clinical results ii) an increase of metastatic genes loss in the NE-CRPC compared to the corresponding hormone sensitive adenocarcinoma. Furthermore, for all the PDX models generated, genomic and mutational analyses revealed specific molecular features and allowed molecular classification depending on tumor stage. Based on the molecular taxonomy of primary prostate cancers, the presented panel covers the different progression steps of the pathology. Considering the scarcity of useful models for PCa and the difficulties to develop such models, the prostate PDX models collection presented here should clearly help understanding disease progression and supporting precision medicine approaches for patients with advanced PCa.

Abstract
Glioblastoma (GBM) is one of the most aggressive types of cancer, which begins within the brain. It is the most invasive type of glioma developed from astrocytes. Until today, Temozolomide (TMZ) is the only standard chemotherapy for patients with GBM. Even though chemotherapy extends the survival of patients, there are many undesirable side effects, and most cases show resistance to TMZ. FL3 is a synthetic flavagline which displays potent anticancer activities, and is known to inhibit cell proliferation, by provoking cell cycle arrest, and leads to apoptosis in a lot of cancer cell lines. However, the effect of FL3 in glioblastoma cancer cells has not yet been examined. Hypoxia is a major problem for patients with GBM, resulting in tumor resistance and aggressiveness. In this study, we explore the effect of FL3 in glioblastoma cells under normoxia and hypoxia conditions. Our results clearly indicate that this synthetic flavagline inhibits cell proliferation and induced senescence in glioblastoma cells cultured under both conditions. In addition, FL3 treatment had no effect on human brain astrocytes. These findings support the notion that the FL3 molecule could be used in combination with other chemotherapeutic agents or other therapies in glioblastoma treatments.

Abstract
Abstract
Background: Muscle-invasive bladder cancers (MIBCs) constitute a heterogeneous group of tumors with poor outcome. Recently, MIBC molecular subtyping efforts from an international consortium led to the identification of six subtypes, improving prediction of clinical outcomes and treatment responses. FGFR3 alterations (mutations and translocations), observed in 20% of MIBCs, are found mainly in the luminal papillary subtype that respond poorly to chemo- and immunotherapy. Basal tumors represent 35% of MIBCs and were shown to be better responders to chemotherapy. Here, we describe the development and characterization of patient-derived primary MIBC xenografts (PDX) belonging to these main subtypes.
Methods: Bladder tumors were obtained from patients at surgery. Tumor fragments were subcutaneously engrafted into immune-compromised mice. Primary tumors and matched PDX tumors at multiple passages were analyzed regarding growth characteristics, histopathology (H&E staining, CK5/6, FOXA1, and GATA3 immunohistochemistry), gene expression (Affymetrix U133 plus 2.0 microarray), and genetic stability (STR profiling). Hotspot oncogenic mutations for FGFR3, PIK3CA, HRAS, KRAS, NRAS, PPARG, and RXRA were also assessed. Additionally, pharmacologic responses to standard-of-care and targeted therapies were characterized.
Findings: From 152 MIBC tumors at all stages and grades, 32 PDX models were successfully established (21.1% success rate). This take rate did not seem correlated to any classical tumor characteristics. Importantly, transcriptomic analysis allowed us to identify PDX models belonging to different molecular subtypes, notably the basal-like and luminal papillary subtypes, including PDXs with FGFR3 mutations. All histologic, genetic, and molecular features validated the stability of the PDX models compared to the parental tumors. Histologic analyses correlated with the molecular classification. These models reproduced the response to cisplatin-based therapies observed in the clinic. Basal models, except one harboring a FGFR3 mutation, were sensitive to anti-EGFR therapies but to a lesser extent than to chemotherapy. FGFR3-mutated PDX models, including a basal model, were highly responsive to FGFR3 inhibitors and less responsive to chemotherapy.
Conclusion: We have developed and characterized highly relevant preclinical models for MIBCs, including basal and FGFR3-mutated tumors, recapitulating molecular heterogeneity and drug responses as observed in patients with MIBCs. They represent essential tools for developing new, efficient therapies against this deadly disease.

Abstract
Abstract
Prostate cancer (PCa) is a highly heterogeneous and complex disease, with evolving treatment options over the course of disease progression. Preclinical PCa research is hampered by a lack of predictive models fully capturing all phases of this multistage disease. Despite progresses in the development of genetically-engineered animal models, these ones do not recapitulate faithfully (i) human disease and (ii) tumor heterogeneity. Models obtained by xenografting human tumors in immunodeficient animals (PDX models, for patient-derived tumor xenografts) remain unavoidable tools in PCa translational and preclinical research since they closely conserve cancer characteristics observed in patients. PDX models are thus invaluable tools to evaluate new potential therapeutic agents. We are presenting here the characteristics of two PDX models derived from the same patient before and after acquisition of the hormone-resistance status. Samples of PCa were obtained from patients at surgery and then subcutaneously xenografted into immunocompromised mice to establish PDX models. After the first growth in mice, they were serially passaged in vivo, considering a model established from P3. PDX tumors at multiple passages and patients’ primary tumors from which they are derived were processed for further analyses. Specifically, we performed histological, genetic (AR, PTEN, P53 and ERG status), transcriptomic (Affymetrix U133 plus 2.0 microarray) and STR profiles analyses. In addition, we also evaluated the responses of the PDX models to androgen deprivation and docetaxel. Since 9 years, 252 prostatic tumors have been collected at all stages. Up to now, 7 PDX models were successfully established (> P3 in mice), i.e. 2.7 % success rate. All histological, genetic and molecular analyses validated the stability of the models compared to the parental tumor. Interestingly, we were able to generate one matched pair of responsive and castration resistant models from the same patient. These two PDX models displayed the major molecular features of the disease in humans including PTEN, TP53 and AR modifications. In addition, in vivo results show heterogeneity of response to androgen deprivation and docetaxel, similar to the responses of patients to these treatments. Considering the scarcity of useful PDX models for PCa and the difficulties to develop such models, the PDX models collection presented here should clearly help to open the road of cure for patients with advanced PCa.

Abstract
Muscle-invasive bladder cancers (MIBCs) constitute a heterogeneous group of tumors with a poor outcome. Recently, MIBC molecular subtyping efforts from an international consortium led to the identification of six subtypes to improve prediction of clinical outcomes and treatment responses. These subtypes can be schematically divided into luminal (differentiated) and non-luminal subtypes. FGFR3 alterations (mutations and translocations) are among the most frequent genetic events in bladder carcinoma and are found mainly in one subtype, the luminal papillary that respond poorly to chemo- and immuno-therapy. Here we describe the development and characterization of patient-derived primary MIBC xenografts (PDX) belonging to these different subtypes. Bladder primary tumors and normal corresponding tissues were directly obtained from patients at surgery. Tumor fragments were subcutaneously xenografted into immune-compromised mice. After the first growth in mice, they were serially passaged. PDXs tumors at multiple passages and patients’ primary tumors from which they are derived were processed for analyses including growth characteristics, histopathology (H&E, CK5/6, FOXA1 and GATA3), gene expression (Affymetrix U133 plus 2.0 microarray), genetic stability (STR profiling).

Abstract
The upregulation of PPARγ/RXRα transcriptional activity has emerged as a key event in luminal bladder tumors. It renders tumor cell growth PPARγ-dependent and modulates the tumor microenvironment to favor escape from immuno-surveillance. The activation of the pathway has been linked to PPARG gains/amplifications resulting in PPARγ overexpression and to recurrent activating point mutations of RXRα. Here, we report recurrent mutations of PPARγ that also activate the PPARγ/RXRα pathway, conferring PPARγ-dependency and supporting a crucial role of PPARγ in luminal bladder cancer. These mutations are found throughout the protein—including N-terminal, DNA-binding and ligand-binding domains—and most of them enhance protein activity. Structure-function studies of PPARγ variants with mutations in the ligand-binding domain allow identifying structural elements that underpin their gain-of-function. Our study reveals genomic alterations of PPARG that lead to pro-tumorigenic PPARγ/RXRα pathway activation in luminal bladder tumors and may open the way towards alternative options for treatment. Activation of the PPARγ/RXRα pathway in luminal bladder cancers has mainly been linked to PPARG gene amplifications and activating point mutations in RXRα. Here, the authors identify recurrent PPARγ mutations with similar effects and elucidate the structural basis for this mutational PPARγ activation.

Abstract
Abstract
Kidney, prostate and bladder cancers (KCa, PCa and BCa, respectively) represent 1 700 000 cases and 450 000 deaths worldwide per year, with an incidence rising yearly by 1-10%. Surgery is usually curative at early and localized stages but there are no efficient therapies at advanced and metastatic stages for any of them. Although genetically-modified and/or chemically-induced avatar models do exist for these cancers and may help to identify new therapeutic targets, they suffer from a lack of an extended biological concordance with the natural history and heterogeneity of the diseases. Patient-derived tumor xenograft models are now well recognized as reliably reproducing tumor heterogeneity and have become over the past few years the preclinical tools of choice to test drugs and identify biomarkers. Since 10 years, we are continuously developing a unique panel of PDX models for these major urological cancers. Tumor tissues along with normal corresponding tissues were obtained from patients at surgery. Patient informed consent and clinical history are available for all patients. Tumor tissues pieces were xenografted subcutaneously in the interscapular space of nude mice, and serially passaged into mice after the first engraftment, up to passage 10. To ensure model stability between primary tumors and tumors growing in mice but also from passage to passage, we performed various analyses at histopathological, genetic (short tandem repeat fingerprinting) and molecular (cDNA profiling) levels. In addition, growth characteristics and responses to standards of care (SOCs) were examined. Finally, specific molecular characteristics were also explored including expression of the androgen receptor, PSA and pan-cytokeratin for PCa models and hotspot mutations of FGFR3, PIK3CA, K/N/H-RAS for BCa models. Up to now, we have xenografted 336 (on 569 samples), 247 and 152 KCa, PCa and BCa tumor tissues, and developed 30 (8.9% success rate), 6 (2.1%) and 30 (19.7%) PDX models, respectively. We recently published part of the KCa PDX models collection (Lang et al., Oncotarget, 2016). Characterization studies showed that PDX models are stable at all levels analyzed considering concordance to primary tumors and from passage to passage; and less than 5% of genes were differentially expressed between the primary tumors and PDX tumors at various passages. Responses to SOCs recapitulated the clinical state. Only for KCa PDX models, the take rate was correlated to tumor stage and grade, and sarcomatoid components. Importantly, several molecular subtypes were defined in our collection of BCa PDX models including PDXs with FGFR3 mutations and PDXs of basal subtype, the most aggressive one. Overall, this panel of PDX models for urological cancers should definitely help to find molecularly guided targeted therapies for these still incurable cancers at metastatic stages.

Abstract
FGFR3 alterations (mutations or translocation) are among the most frequent genetic events in bladder carcinoma. They lead to an aberrant activation of FGFR3 signaling, conferring an oncogenic dependence, which we studied here. We discovered a positive feedback loop, in which the activation of p38 and AKT downstream from the altered FGFR3 upregulates MYC mRNA levels and stabilizes MYC protein, respectively, leading to the accumulation of MYC, which directly upregulates FGFR3 expression by binding to active enhancers upstream from FGFR3 Disruption of this FGFR3/MYC loop in bladder cancer cell lines by treatment with FGFR3, p38, AKT, or BET bromodomain inhibitors (JQ1) preventing MYC transcription decreased cell viability in vitro and tumor growth in vivo A relevance of this loop to human bladder tumors was supported by the positive correlation between FGFR3 and MYC levels in tumors bearing FGFR3 mutations, and the decrease in FGFR3 and MYC levels following anti-FGFR treatment in a PDX model bearing an FGFR3 mutation. These findings open up new possibilities for the treatment of bladder tumors displaying aberrant FGFR3 activation.

Abstract
The objective of the present work was to establish a large panel of preclinical models of human renal cell carcinoma (RCC) directly from patients, faithfully reproducing the biological features of the original tumor. RCC tissues (all stages/subtypes) were collected for 8 years from 336 patients undergoing surgery, xenografted subcutaneously in nude mice, and serially passaged into new mice up to 13 passages. Tissue samples from the primary tumor and tumors grown in mice through passages were analyzed for biological tissue stability by histopathology, mRNA profiling, von Hippel-Lindau gene sequencing, STR fingerprinting, growth characteristics and response to current therapies. Metastatic models were also established by orthotopic implantation and analyzed by imagery. We established a large panel of 30 RCC models (passage > 3, 8.9% success rate). High tumor take rate was associated with high stage and grade. Histopathologic, molecular and genetic characteristics were preserved between original tumors and case-matched xenografts. The models reproduced the sensitivity to targeted therapies observed in the clinic. Overall, these models constitute an invaluable tool for the clinical design of efficient therapies, the identification of predictive biomarkers and translational research.

Abstract
Polydiacetylenic nanofibers (PDA-Nfs) obtained by photopolymerization of surfactant 1 were optimized for intracellular delivery of small interfering RNAs (siRNAs). PDA-Nfs/siRNA complexes efficiently silenced the oncogene Lim-1 in the renal cancer cells 786-O in vitro. Intraperitoneal injection of PDA-Nfs/siLim1 downregulated Lim-1 in subcutaneous tumor xenografts obtained with 786-O cells in nude mice. Thus, PDA-Nfs represent an innovative system for in vivo delivery of siRNAs.

Abstract
Injury of mesangial cells (MC) is a prominent feature of glomerulonephritis. Activated MC secrete inflammatory mediators that induce cell apoptosis. Parathyroid hormone-related peptide (PTHrP) is a locally active cytokine that enhances cell survival and is upregulated by proinflammatory factors in many cell types. The aim of this study was to analyze the regulation of PTHrP expression by inflammatory cytokines and to evaluate whether PTHrP itself acts as a proinflammatory and/or survival factor on male murine MC in primary culture. Our results showed that IL-1β (10 ng/ml) and TNF-α (10 ng/ml) rapidly and transiently upregulated PTHrP expression in MC. The effects of IL-1β were both transcriptional and posttranscriptional, with stabilization of the PTHrP mRNA by human antigen R (HuR). Proteome profiler arrays showed that PTHrP itself enhanced cytokines within 2 h in cell lysates, mainly IL-17, IL-16, IL-1α, and IL-6. PTHrP also stimulated sustained expression (2-4 h) of chemokines, mainly regulated upon activation normal T cell expressed and secreted (RANTES)/C-C motif chemokine 5 (CCL5) and macrophage inflammatory protein-2 (MIP-2)/C-X-C motif chemokine 2 (CXCL2), thymus and activation-regulated chemokine (TARC)/CCL17, and interferon-inducible T cell α-chemoattractant (I-TAC)/CXCL11. Moreover, PTHrP markedly enhanced cyclooxygenase-2 (COX-2) expression and elicited its autoinduction through the activation of the NF-κB pathway. PTHrP induced MC survival via the COX-2 products, and PTHrP overexpression in MC blunted the apoptotic effects of IL-1β and TNF-α. Altogether, these findings suggest that PTHrP functions as a booster of glomerular inflammatory processes and may be a negative feedback loop preserving MC survival.

Abstract
Abstract
Prostate, bladder and kidney cancers represent 1 900 000 new cases and 620 000 deaths per year worldwide with an incidence increasing by 1-10% each year. Surgery is curative at localized stages; however, current therapies are inefficient at advanced stages. One of the major needs in new drugs development is the availability of clinically pertinent models faithfully reproducing the heterogeneity of patient tumors. Patient-derived tumor xenografts (PDX) are thus developed as essential tools for drug testing and identification of predictive biomarkers for a better clinical response, the first step for personalized medicine.
Prostate, bladder and kidney tumors were obtained from patients undergoing surgery, subcutaneously (and some orthopically) xenografted in nude mice and serially passaged up to passage (P) 12. Normal corresponding tissues were also harvested. Tissues were conserved at all passages for characterization and grafting. For all patients, informed consent and clinical history are available. For the 3 cancers, primary tumor and tumors grown in mice were characterized for growth behavior, histopathology, genetic stability (short tandem repeat fingerprinting), mRNA expression profiling and response to current therapies. For each cancer type, we also investigated more specific features: expression of the androgen receptor, PSA and pan-cytokeratin for prostate PDXs, expression and status of hotspot mutations including FGFR3, PIK3CA, HRAS, RXRa and p53 for bladder PDXs, and von Hippel-Lindau gene mutation status for kidney PDXs. Metastatic models were followed by infrared imagery (IR780 dye).
So far and since 9 years, we have collected 230 prostate tumors, 130 bladder tumors and 336 kidney tumors at all stages, and established 5, 25 and 31 models (> P3 in mice) respectively (8.8% success rate). Tumor take rate was positively correlated to advanced stage and high grade and for kidney cancer, to sarcomatoid component. Tumor growth evaluation reveals that PDXs were stable from mouse to mouse and throughout passages. Histopathologic and genetic characteristics were preserved between original tumors and case-matched PDXs. Molecular characteristics were also stable with less than 5% of genes differentially expressed between the primary tumors and the PDXs. In bladder PDXs, this analysis and mutation status of the selected genes allowed to define molecular subtypes. The comparison with patient therapeutic response, when available, showed the clinical predictivity of the models. Orthotopic models developed metastases at classical sites.
In conclusion, we developed here a unique platform of preclinical PDXs models for urologic cancers with stable biological characteristics and clinically predictive. This is an invaluable tool for the clinical design of efficient therapies, the identification of predictive biomarkers and translational research.

Abstract
Low-dose exposures to common environmental chemicals that are deemed safe individually may be combining to instigate carcinogenesis, thereby contributing to the incidence of cancer. This risk may be overlooked by current regulatory practices and needs to be vigorously investigated. Lifestyle factors are responsible for a considerable portion of cancer incidence worldwide, but credible estimates from the World Health Organization and the International Agency for Research on Cancer (IARC) suggest that the fraction of cancers attributable to toxic environmental exposures is between 7% and 19%. To explore the hypothesis that low-dose exposures to mixtures of chemicals in the environment may be combining to contribute to environmental carcinogenesis, we reviewed 11 hallmark phenotypes of cancer, multiple priority target sites for disruption in each area and prototypical chemical disruptors for all targets, this included dose-response characterizations, evidence of low-dose effects and cross-hallmark effects for all targets and chemicals. In total, 85 examples of chemicals were reviewed for actions on key pathways/mechanisms related to carcinogenesis. Only 15% (13/85) were found to have evidence of a dose-response threshold, whereas 59% (50/85) exerted low-dose effects. No dose-response information was found for the remaining 26% (22/85). Our analysis suggests that the cumulative effects of individual (non-carcinogenic) chemicals acting on different pathways, and a variety of related systems, organs, tissues and cells could plausibly conspire to produce carcinogenic synergies. Additional basic research on carcinogenesis and research focused on low-dose effects of chemical mixtures needs to be rigorously pursued before the merits of this hypothesis can be further advanced. However, the structure of the World Health Organization International Programme on Chemical Safety ‘Mode of Action’ framework should be revisited as it has inherent weaknesses that are not fully aligned with our current understanding of cancer biology.

Abstract
One of the important 'hallmarks' of cancer is angiogenesis, which is the process of formation of new blood vessels that are necessary for tumor expansion, invasion and metastasis. Under normal physiological conditions, angiogenesis is well balanced and controlled by endogenous proangiogenic factors and antiangiogenic factors. However, factors produced by cancer cells, cancer stem cells and other cell types in the tumor stroma can disrupt the balance so that the tumor microenvironment favors tumor angiogenesis. These factors include vascular endothelial growth factor, endothelial tissue factor and other membrane bound receptors that mediate multiple intracellular signaling pathways that contribute to tumor angiogenesis. Though environmental exposures to certain chemicals have been found to initiate and promote tumor development, the role of these exposures (particularly to low doses of multiple substances), is largely unknown in relation to tumor angiogenesis. This review summarizes the evidence of the role of environmental chemical bioactivity and exposure in tumor angiogenesis and carcinogenesis. We identify a number of ubiquitous (prototypical) chemicals with disruptive potential that may warrant further investigation given their selectivity for high-throughput screening assay targets associated with proangiogenic pathways. We also consider the cross-hallmark relationships of a number of important angiogenic pathway targets with other cancer hallmarks and we make recommendations for future research. Understanding of the role of low-dose exposure of chemicals with disruptive potential could help us refine our approach to cancer risk assessment, and may ultimately aid in preventing cancer by reducing or eliminating exposures to synergistic mixtures of chemicals with carcinogenic potential.

Abstract
Human conventional renal cell carcinoma (CCC) remains resistant to current therapies. Focal Adhesion Kinase (FAK) is upregulated in many epithelial tumors and clearly implicated in nearly all facets of cancer. However, only few reports have assessed whether FAK may be associated with renal tumorigenesis. In this study, we investigated the potential role of FAK in the growth of human CCC using a panel of CCC cell lines expressing or not the von Hippel-Lindau (VHL) tumor suppressor gene as well as normal/tumoral renal tissue pairs. FAK was found constitutively expressed in human CCC both in culture cells and freshly harvested tumors obtained from patients. We showed that CCC cell growth was dramatically reduced in FAK-depleted cells or after FAK inhibition with various inhibitors and this effect was obtained through inhibition of cell proliferation and induction of cell apoptosis. Additionally, our results indicated that FAK knockdown decreased CCC cell migration and invasion. More importantly, depletion or pharmacological inhibition of FAK substantially inhibited tumor growth in vivo. Interestingly, investigations of the molecular mechanism revealed loss of FAK phosphorylation during renal tumorigenesis impacting multiple signaling pathways. Taken together, our findings reveal a previously uncharacterized role of FAK in CCC whereby FAK exerts oncogenic properties through a non canonical signaling pathway involving its scaffolding kinase-independent properties. Therefore, targeting the FAK scaffold may represent a promising approach for developing innovative and highly specific therapies in human CCC.

Abstract
Parathyroid hormone-related protein (PTHrP) belongs to vasoactive factors that regulate blood pressure and renal hemodynamics both by reducing vascular tone and raising renin release. PTHrP is expressed in systemic and renal vasculature. Here, we wanted to assess the contribution of vascular smooth muscle cell endogenous PTHrP to the regulation of cardiovascular and renal functions. We generated a mouse strain (SMA-CreERT2/PTHrPL2/L2 or premutant PTHrPSM-/-), which allows temporally controlled, smooth muscle-targeted PTHrP knockdown in adult mice. Tamoxifen treatment induced efficient recombination of PTHrP-floxed alleles and decreased PTHrP expression in vascular and visceral smooth muscle cells of PTHrPSM-/- mice. Blood pressure remained unchanged in PTHrPSM-/- mice, but plasma renin concentration and creatinine clearance were reduced. Renal hemodynamics were further analyzed during clearance measurements in anesthetized mice. Conditional knockdown of PTHrP decreased renal plasma flow and glomerular filtration rate with concomitant reduction in filtration fraction. Similar measurements were repeated during acute saline volume expansion. Saline volume expansion induced a rise in renal plasma flow and reduced filtration fraction; both were blunted in PTHrPSM-/- mice leading to impaired diuresis. These findings show that endogenous vascular smooth muscle PTHrP controls renal hemodynamics under basal conditions, and it is an essential factor in renal vasodilation elicited by saline volume expansion.

Abstract
Abstract
Kidney, bladder and prostate cancers are the 3 prevalent urological cancers. They represent each year 1 500 000 new cases and 500 000 deaths worldwide with an incidence increasing steadily by 2-10% per year. At advanced stages, current first-line therapies are inefficient. One of the major needs in new drugs development is the availability of a large panel of clinically pertinent models representing patients’ heterogeneity. In addition, our ability to tailor specific drugs to patients is restricted by the lack of validated biomarkers and might be considered as the most important barrier for a better clinical response.
Kidney, bladder and prostate tumor tissues at all stages were collected from patients undergoing surgery, xenografted in nude mice, and serially passaged into new mice. All tumors were implanted subcutaneously and some of them orthotopically. Informed consent and clinical history were obtained for all patients. For all 3 cancer types, tissue samples from the patients’ primary tumor and tumors grown in mice through passages were analyzed for primary tumor-models stability by histopathology, mRNA expression profiling, growth behavior and response to first-line therapies (sunitinib/sorafenib/everolimus, cisplatin and docetaxel for kidney, bladder and prostate cancer respectively). In addition, for each cancer type and models derived from it, we also analyzed more specific tumor characteristics for their stability: the VHL status and the genetic stability by short tandem repeat fingerprinting for kidney cancer; the expression of interest genes including FGFR3, HRAS or p53 genes for bladder cancer, and the expression/mutations of the androgen receptor and the expression of prostate specific antigen and cytokeratin for prostate cancer. Orthotopic models were followed by infrared imaging after intravenous injection of the IR780 dye.
So far and since 2007, we have xenografted 380 kidney tumors, 80 bladder tumors and 150 prostate tumors, out of which we have established 31, 11 and 3 models (passage above 3 and up to 12 in mice), respectively. The tumor take rate in mice (7.4% overall success) was significantly correlated with tumor stages, but not with any other tumor features. Importantly, tumors were stable through passages at the histopathologic, molecular and genetic levels. In addition, the responsiveness of tumors grown in mice to current therapies compounds was similar to patients’ therapeutic responses, also highlighting the clinical predictivity of our models. Orthotopic models developed metastases at classical secondary sites.
We developed a unique platform of well characterized, stable and clinically predictive mouse xenograft urological cancer models. This is an invaluable tool for the clinical design of efficient therapies and for the identification of predictive biomarkers.

Abstract
Glomerulonephritis is characterized by the proliferation and apoptosis of mesangial cells (MC). The parathyroid-hormone related protein (PTHrP) is a locally active cytokine that affects these phenomena in many cell types, through either paracrine or intracrine pathways. The aim of this study was to evaluate the effect of both PTHrP pathways on MC proliferation and apoptosis. In vitro studies were based on MC from male transgenic mice allowing PTHrP-gene excision by a CreLoxP system. MC were also transfected with different PTHrP constructs: wild type PTHrP, PTHrP devoid of its signal peptide, or of its nuclear localization sequence. The results showed that PTHrP deletion in MC reduced their proliferation even in the presence of serum and increased their apoptosis when serum-deprived. PTH1R activation by PTHrP(1-36) or PTH(1-34) had no effect on proliferation but improved MC survival. Transfection of MC with PTHrP devoid of its signal peptide significantly increased their proliferation and minimally reduced their apoptosis. Overexpression of PTHrP devoid of its nuclear localization sequence protected cells from apoptosis without changing their proliferation. Wild type PTHrP transfection conferred both mitogenic and survival effects, which seem independent of midregion and C-terminal PTHrP fragments. PTHrP-induced MC proliferation was associated with p27(Kip1) down-regulation and c-Myc/E2F1 up-regulation. PTHrP increased MC survival through the activation of cAMP/protein kinase A and PI3-K/Akt pathways. These results reveal that PTHrP is a cytokine of multiple roles in MC, acting as a mitogenic factor only through an intracrine pathway, and reducing apoptosis mainly through the paracrine pathway. Thus, PTHrP appears as a probable actor in MC injuries.

Abstract
Several genes play essential roles in human development and alteration of their expression or regulation leads to various pathologies. This review examines the literature on the expression and the roles of neurogenic locus notch homolog protein (NOTCH), sonic Hedgehog (SHH) and wingless-type (WNT) pathways, as well as the nephrogenic transcription factors Wilms' tumor 1 (WT1), paired box 2 (PAX2) and homeobox protein lim-1 (LIM1) in clear cell renal cell carcinoma. Besides being re-expressed in human tumors, the inhibition of these factors has strong antitumor activity both in vitro and in vivo. Interestingly, these pathways are also part of the molecular network involved in the development of organs including nephrogenesis. The identification of developmental pathways involved in clear cell renal cell carcinoma growth places an additional piece into the molecular puzzle of cancer mechanisms. Moreover, the evaluation of these molecules could pave the way to innovative and safe therapies for this refractory disease. Valuable prognostic markers might also be identified through these studies. Finally, the proof of concept in other types of cancer is reviewed.

Abstract
Human clear cell renal cell carcinoma (CCC) remains resistant to treatments despite the progress in targeted therapies. Several signaling pathways acting during renal development are reactivated during kidney tumorigenesis; this is the case of the sonic hedgehog (SHH)-Gli. Interestingly, the precursor of active vitamin D3 (VD3), cholecalciferol, has been demonstrated to be a strong inhibitor of SHH-Gli signaling. Here, we show the preclinical efficacy of cholecalciferol in CCC both in vitro and in vivo. A panel of CCC cell lines, tumors and normal corresponding tissues from CCC patients were used to evaluate the expression of the VD3 receptor and metabolizing enzymes and the effects of cholecalciferol treatment. Subsequently, xenografted mice were treated with cholecalciferol in a prophylactic or therapeutic manner; their response and the adverse effects were evaluated on the basis of weekly monitoring, followed by blood collection procedures and X-ray micro-computed tomography. VD3 receptor and metabolizing enzymes are dramatically decreased in human cell lines and tumors. Cholecalciferol decreases cell proliferation and increases cell death by inhibition of the SHH-Gli pathway. Xenografted mice treated with cholecalciferol exhibit absence of tumor development or substantial growth inhibition. The treatment was shown to be safe; it did not induce calcification or calcium reabsorption. These findings establish that, although VD3 receptors and metabolizing enzymes are absent in CCC, cholecalciferol supplementation is a strong tool to block the reactivation of SHH-Gli pathway in this pathology, leading ultimately to tumor regression. Cholecalciferol may have highly therapeutic potential in CCC.

Abstract
Human clear cell renal cell carcinoma (CCC) remains resistant to therapies. The transcription factor LIM-class homeobox gene Lim1 is required for normal organogenesis, including nephrogenesis, by regulating cell movements, differentiation and growth. Its expression is controlled partly by the sonic hedgehog-Gli signaling pathway, which we have recently shown to be reactivated in human CCC. So far, no study has assessed whether Lim1 may be associated with tumorigenesis. Using a panel of human CCC cell lines expressing or not the von Hippel-Lindau tumor suppressor gene and 44 tumor/normal tissues pairs, we found that Lim1 is constitutively and exclusively reexpressed in tumors. Through Lim1 silencing or overexpressing, we show that Lim1 is a growth and survival factor in human CCC, at least through the activation of oncogenic pathways including the phosphoinositide kinase-3/Akt and nuclear factor-kappaB pathways. More importantly, in nude mice bearing human CCC tumors, Lim1 silencing abolished tumor growth through the same mechanism as in vitro. In Lim1-depleted cells and tumors, cell movements were substantially impaired because of the inhibition of expression of various proteins involved in metastatic spread, such as paxillin or tenascin-C. These findings establish that the developmental marker Lim1 acts as an oncogene in cancer cells and targeting Lim1 may constitute an innovative therapeutic intervention in human CCC.

Abstract
Human conventional renal cell carcinoma (CRCC) remains resistant to therapy. The RNA-binding protein HuR regulates the stability and/or translation of multiple messenger RNAs involved in malignant transformation. In this study, we aimed to evaluate the potential role of HuR in this pathology. Using seven human CRCC cell lines expressing or not the von Hippel-Lindau (VHL) tumor suppressor gene as well as 15 normal/renal cell carcinoma tumor pairs, we showed that HuR is overexpressed in all tumors independently of the VHL status. Futhermore, HuR cytoplasmic presence appears to be more common in early tumor stages, suggesting a role in tumor promotion. We then assessed the effect of HuR knockdown using small interfering RNA in cultured cell and in tumor-bearing mice. Both in vitro and in vivo, we observed that cell growth was inhibited by 60% and that this effect was obtained through an inhibition of cell proliferation and an induction of cell apoptosis. Finally, we found that expression of vascular endothelium growth factor, tumor growth factor-beta and of the hypoxia-induced transcription factor-2alpha as well as the constitutive activation of the oncogenic phosphoinositide 3-kinase/Akt, nuclear factor-kappaB and mitogen-activated protein kinase pathways were decreased in HuR-depleted cells and tumors. All these results suggest a pivotal role for HuR in human CRCC.

Abstract
Background Human clear cell renal cell carcinoma (CRCC) remains resistant to therapies. Recent advances in Hypoxia Inducible Factors (HIF) molecular network led to targeted therapies, but unfortunately with only limited clinical significance. Elucidating the molecular processes involved in kidney tumorigenesis and resistance is central to the development of improved therapies, not only for kidney cancer but for many, if not all, cancer types. The oncogenic PI3K/Akt, NF-kB and MAPK pathways are critical for tumorigenesis. The sonic hedgehog (SHH) signaling pathway is crucial to normal development. Results By quantitative RT-PCR and immunoblot, we report that the SHH signaling pathway is constitutively reactivated in tumors independently of the von Hippel-Lindau (VHL) tumor suppressor gene expression which is inactivated in the majority of CRCC. The inhibition of the SHH signaling pathway by the specific inhibitor cyclopamine abolished CRCC cell growth as assessed by cell counting, BrdU incorporation studies, fluorescence-activated cell sorting and β-galactosidase staining. Importantly, inhibition of the SHH pathway induced tumor regression in nude mice through inhibition of cell proliferation and neo-vascularization, and induction of apoptosis but not senescence assessed by in vivo studies, immunoblot and immunohistochemistry. Gli1, cyclin D1, Pax2, Lim1, VEGF, and TGF-β were exclusively expressed in tumors and were shown to be regulated by SHH, as evidenced by immunoblot after SHH inhibition. Using specific inhibitors and immunoblot, the activation of the oncogenic PI3K/Akt, NF-kB and MAPK pathways was decreased by SHH inhibition. Conclusions These findings support targeting SHH for the treatment of CRCC and pave the way for innovative and additional investigations in a broad range of cancers.

Abstract
We have shown that parathyroid hormone-related protein (PTHrP) is a survival factor for human renal cell carcinoma (RCC) and that its expression is negatively regulated by the von Hippel-Lindau (VHL) tumor suppressor gene at the level of messenger RNA (mRNA) stability, as observed for tumor growth factors (TGFs). Our goals were to analyze the alternative splicing of PTHrP mRNA in human RCC and from these results to identify VHL/hypoxia-induced factor (HIF) system-regulated mRNA-binding proteins involved in PTHrP mRNA stability. We used: (i) a panel of human RCC cells expressing or not VHL; (ii) VHL-deficient 786-0 cells transfected with active or inactive VHL and (iii) human RCC samples and corresponding normal tissues. By quantitative real-time reverse transcription-polymerase chain reaction analysis, the 141 PTHrP mRNA isoform was found to be predominant in all cells and tumors (80%). In cells transfected with VHL, the expressions of all isoforms were decreased by 50%. Eight proteins with molecular weights ranging from 20 to 75 kDa were found to bind to biotinylated transcripts spanning the 141 PTHrP mRNA AU-rich 3'-untranslated region whose abundancy was dependent on VHL expression. The protein having an apparent molecular weight of 30 kDa was identified by western blot as HuR, a RNA-binding protein with stabilizing functions on various mRNA coding for proteins important in malignant transformation including vascular endothelial growth factor and TGF-beta. PTHrP expression studies confirmed the involvement of HuR in PTHrP upregulation in this disease. Common mRNA-binding proteins regulated by the VHL/HIF system may constitute new therapeutic opportunities against human RCC that remains refractory to therapies.

Abstract
Metastatic renal cell carcinoma (RCC) remains refractory to therapies. The nuclear factor-kappaB (NF-kappaB) transcription factor is involved in cell growth, cell motility, and vascularization. We evaluated whether targeting NF-kappaB could be of therapeutic and prognostic values in human RCC. The activation of the NF-kappaB pathway in human RCC cells and tumors was investigated by Western blot. In vitro, the effects of BAY 11-7085 and sulfasalazine, two NF-kappaB inhibitors, on tumor cell growth were investigated by cell counting, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide analysis, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling, and fluorescence-activated cell sorting. Their specificity toward NF-kappaB was analyzed by Western blot, confocal microscopy, NF-kappaB small interfering RNA, and NF-kappaB transcription assay. In vivo, the effects of BAY 11-7085 on the growth of human RCC tumors were investigated in nude mice. A tissue microarray (TMA) containing 241 cases of human RCC with 12 to 22 years of clinical follow-up and corresponding normal tissues was built up to assess prognostic significance of activated NF-kappaB. NF-kappaB is constitutively activated in cultured cells expressing or not the von Hippel-Lindau (VHL) tumor suppressor gene as a consequence of Akt kinase activation and in tumors. In vitro and in vivo NF-kappaB inhibition blocked tumor cell growth by inducing cell apoptosis. On the TMA, NF-kappaB activation was correlated with tumor dimension but was not found to be an independent prognostic factor for patient survival. This report provides strong evidence that the mechanisms responsible for the intrinsic resistance of RCC cells to apoptosis converge on NF-kappaB independently of VHL expression and that targeting this pathway has great anticancer potential.

Abstract
We have recently shown that parathyroid hormone-related protein (PTHrP), a cytokine-like polyprotein, is critical for human renal cell carcinoma (RCC) growth by inhibiting tumor cell apoptosis. Here, we have explored mechanisms by which PTHrP controls tumor cell survival. Using specific inhibitors of phosphoinositide 3-kinase (PI3K) and depletion of Akt kinase by RNA interference, we established that PTHrP is one of the main factor involved in the constitutive activation of this pathway in human RCC, independently of von Hippel-Lindau (VHL) tumor suppressor gene expression. Interestingly, PTHrP induced phosphorylation of Akt at S473 but had no influence on phosphorylation at T308. Through transfection with integrin-linked kinase (ILK) constructs and RNA interference, we provide evidence that ILK is involved in human RCC cell survival. PTHrP activates ILK which then acts as a phosphoinositide-dependent kinase (PDK)-2 or a facilitator protein to phosphorylate Akt at S473. Among other kinases tested, only ILK was shown to exert this function in RCC. Using specific inhibitors, western blot and transcription assay, we identified nuclear factor kappa B (NF-kappaB) as the downstream Akt target regulated by PTHrP. Since RCC remains refractory to current therapies, our results establish that the PI3K/ILK/Akt/NF-kappaB axis is a promising target for therapeutic intervention.

Abstract
We previously reported that PTHrP-induced renal vasodilation is impaired in mature spontaneously hypertensive rats (SHR) through down-regulation of the type 1 PTH/PTHrP receptor (PTH1R), a feature that contributes to the high renal vascular resistance in SHR. Here we asked whether this defect represents a prime determinant in genetic hypertension or whether it is secondary to angiotensin II (Ang II) and/or the mechanical forces exerted on the vascular wall. We found that the treatment of SHR with established hypertension by the Ang II type 1 receptor antagonist, losartan, reversed the down-regulation of PTH1R expression in intrarenal small arteries and restored PTHrP-induced vasodilation in ex vivo perfused kidneys. In contrast, the PTH1R deregulation was not found in intrarenal arteries isolated from prehypertensive SHR. Moreover, this defect, which is not seen in extrarenal vessels (aorta, mesenteric arteries) from mature SHR appeared kidney specific in accordance with the acknowledged enrichment of interstitial Ang II in this organ and its enhancement in SHR. In deoxycorticosterone-acetate-salt rats, an Ang II-independent model of hypertension, renovascular PTH1R expression and related vasodilation were not altered. In SHR-derived renovascular smooth muscle cells (RvSMCs), the PTH1R was spontaneously down-regulated and its transcript destabilized, compared with Wistar RvSMCs, both effects being antagonized by losartan. Exogenous Ang II elicited down-regulation of PTH1R mRNA in RvSMCs from Wistar rats. Together, these data demonstrate that Ang II acts via the Ang II type 1 receptor to destabilize PTH1R mRNA in the renal vessel in the SHR model of genetic hypertension. This process is kidney specific and independent from blood pressure increase.

Abstract
The Fuhrman nuclear grade is the reference histoprognostic grading system routinely used all over the world for renal cell carcinoma. Studies measuring the inter-observer and intra-observer concordance of Fuhrman grade show poor results in terms of reproducibility and repeatability. These variations are due to a certain degree of subjectivity of the pathologist in application of the definition of tumour grade, particularly nuclear grade. Elements able to account for this subjectivity in renal cell carcinoma are identified from a review of the literature. To improve the reliability of nuclear grade, the territory occupied by the highest grade must be specified and the grades should probably be combined. At the present time, regrouping of grade 1 and 2 tumours as low grade and grade 3 and 4 tumours as high grade would achieve better reproducibility, while preserving the prognostic: value for overall survival. The development of new treatment modalities and their use in adjuvant situations will imply the use of reliable histoprognostic factors to specify, indications.

Abstract
Metastatic renal cell carcinoma is resistant to current therapies. The phosphoinositide 3-kinase (PI3K)/Akt signaling cascade induces cell growth, cell transformation, and neovascularization. We evaluated whether targeting this pathway could be of therapeutic value against human renal cell carcinoma. The activation of the PI3K/Akt pathway and its role in renal cell carcinoma progression was evaluated in vitro in seven human cell lines by Western blot, cell counting, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, terminal deoxyribonucleotide transferase-mediated nick-end labeling assays, and fluorescence-activated cell sorting analysis, using two PI3K inhibitors, LY294002 and wortmannin, as well as by transfection with various Akt constructs and through Akt knockdown by small interfering RNA (siRNA). In vivo nude mice bearing human renal cell carcinoma tumor xenografts were treated with LY294002 (75 mg/kg/wk, 4 weeks, i.p.). Tumor growth was measured and tumors were subjected to Western blot and immunohistochemical analysis. Akt was constitutively activated in all cell lines. Constitutive phosphorylation of glycogen synthase kinase-3 (GSK-3) was observed in all cell lines, whereas forkhead transcription factor and mammalian target of rapamycin, although expressed, were not constitutively phosphorylated. Exposure to LY294002 or wortmannin decreased Akt activation and GSK-3 phosphorylation and reduced cell growth by up to 70% through induction of cell apoptosis. These effects were confirmed by transfection experiments with Akt constructs or Akt siRNA. Importantly, LY294002 induced up to 50% tumor regression in mice through tumor cell apoptosis. Tumor neovascularization was significantly increased by LY294002 treatment. Blood chemistries showed no adverse effects of the treatment. Our results suggest an important role of PI3K/Akt inhibitors as a potentially useful treatment for patients with renal cell carcinoma.

Abstract
Parathyroid hormone-related protein (PTHrP), a polyprotein discovered in 1987, plays crucial roles not only in development and in various physiological events associated with normal life, but also in a number of pathological conditions such as cancer. PTHrP appears as the major causative agent in humoral hypercalcemia of malignancy (HHM) associated to a broad range of tumors. However, this is only one aspect of the multiple facets of PTHrP in cancer biology. Indeed, the complex growth factor-like properties of PTHrP has shed new light onto potential roles of this peptide in the regulation of tumor growth and invasion. Initial studies in breast, prostate and lung cancer and recent results in renal cell carcinoma (RCC) suggest such roles and highlight the therapeutic potential of PTHrP-targeting strategies in human cancer including RCC. In this review, the role of PTHrP in RCC tumorigenesis and its potential as a therapeutic target will be discussed.

Abstract
Functional inactivation of the von Hippel-Lindau (VHL) tumor suppressor gene occurs in 40-80% of human conventional renal cell carcinomas (RCCs). We showed recently that VHL-deficient RCCs expressed large amounts of parathyroid hormone-related protein (PTHrP), and that PTHrP, acting through the PTH1 receptor (PTH1R), plays an essential role in tumor growth. We also showed that PTHrP expression is negatively regulated by the VHL gene products (pVHL). Our goal was to determine whether blocking the PTHrP/PTH1R system might be of therapeutic value against RCC, independent of VHL status and PTHrP expression levels. The antitumor activity of PTHrP neutralizing antibody and of PTH1R antagonist were evaluated in vitro and in vivo in a panel of human RCC lines expressing or not pVHL. PTHrP is upregulated compared with normal tubular cells. In vitro, tumor cell growth and viability was decreased by up to 80% by the antibody in all cell lines. These effects resulted from apoptosis. Exogenously added PTHrP had no effect on cell growth and viability, but reversed the inhibitory effects of the antibody. The growth inhibition was reproduced by a specific PTH1R antagonist in all cell lines. In vivo, the treatment of nude mice bearing the Caki-1 RCC tumor with the PTHrP antibody inhibited tumor growth by 80%, by inducing apoptosis. Proliferation and neovascularization were not affected by the antiserum. Anti-PTHrP treatment induced no side effects as assessed by animal weight and blood chemistries. Current therapeutic strategies are only marginally effective against metastatic RCC, and adverse effects are common. This study provides a rationale for evaluating the blockade of PTHrP signaling as therapy for human RCC in a clinical setting.

Abstract
In vivo, vascular smooth muscle cells (VSMC) are continuously exposed to mechanical cyclic stretch as a result of the pulsatile blood flow from the cardiac contractile cycle. Stretch is altered in pathologic conditions and contributes to vascular remodeling by modulating VSMC proliferation and death. Parathyroid hormone-related protein (PTHrP) is a locally produced poly-protein that regulates cell growth. It was shown previously that PTHrP inhibits VSMC proliferation through the auto/paracrine pathway by interacting with its receptor, the PTH1R, but stimulates VSMC proliferation through the intracrine pathway by translocating into the nucleus. In the current study, VSMC that were isolated from both resistance and compliance vessels were used to study the role of PTHrP in VSMC proliferation under experimental stretch. It is shown that PTHrP gene expression is upregulated by stretch and that PTHrP opposes the inhibitory effect induced by stretch on VSMC proliferation through the intracrine pathway. In addition, it is demonstrated that PTHrP expression is controlled at the post-transcriptional level by stretch. Taken together, these results strongly suggest that PTHrP plays a critical role in the modulation of VSMC proliferation in response to stretch. Thus, in conditions in which stretch is increased, such as in hypertension or in restenosis after angioplasty, PTHrP may contribute to vessel hyperplasia.
