Les tumeurs de vessie suivent deux voies de progression tumorale. La voie des carcinomes in situ (CIS) qui progressent pour envahir la membrane basale puis le muscle, et la voie des tumeurs papillaires de bas grade qui progressent peu mais qui récidivent fréquemment. Environ 65% des tumeurs papillaires de bas grade présentent une mutation du gène FGFR3 et récemment des protéines de fusion FGFR3-TACC3 ont été observées dans les tumeurs de vessie (dans 10% des tumeurs invasives). Le rôle oncogénique du récepteur FGFR3 muté et de FGFR3-TACC3 a été démontré in vivo et in vitro. Cependant, les voies de signalisation du récepteur FGFR3 muté ou de FGFR3-TACC3 sont à l’heure actuelle très peu caractérisées. Dans ce contexte, deux approches ont été mises en place pour caractériser ces voies de signalisation. La première s’appuie sur l’étude de la phosphorylation des protéines p38, AKT et ERK1/2 par le récepteur FGFR3 muté (S249C) ou sauvage dans la lignée cellulaire fibroblastique NIH3T3, et a permis d’identifier les protéines p38 et AKT comme activées par le récepteur FGFR3 muté et nécessaire pour induire la transformation cellulaire. L’étude de l’activation de ces deux voies de signalisation a été réalisée dans des lignées cellulaires dérivées de tumeurs de vessie exprimant le récepteur FGFR3 muté ou FGFR3-TACC3 de manière endogène et a montré que leur activation était dépendante de celle du récepteur FGFR3. De plus nous avons montré que les protéines p38 et AKT sont impliquées dans le maintien d’une boucle de rétro-contrôle positive entre FGFR3 et MYC : l’activation de FGFR3 induit une surexpression de MYC qui en retour promeut l’expression de FGFR3. La seconde approche est basée sur une étude visant à identifier les partenaires protéiques de FGFR3 par spectrométrie de masse après immunoprécipitation de celui-ci qui avait été réalisée précédemment au laboratoire. L’analyse des données a permis l’obtention d’une liste de 60 protéines identifiées comme partenaires protéiques de FGFR3 avec une grande confiance. La construction d’un réseau à partir de cette liste n’a pas été possible (trop peu d’interactions existant entre ces protéines), nous avons donc développé un algorithme (PEPPER) en collaboration avec un étudiant en bio-informatique au laboratoire, Rémy Nicolle, pour proposer un réseau de signalisation de FGFR3.Les deux approches mises en place au cours de cette thèse nous ont permis de mieux caractériser les voies de signalisation du récepteur FGFR3. L’identification d’une boucle de rétrocontrôle entre FGFR3 et MYC a permis de mieux comprendre pourquoi le récepteur FGFR3 possède des propriétés oncogéniques, et de proposer les protéines p38 et AKT comme cibles thérapeutiques potentielles pour traiter les tumeurs de vessie exprimant le récepteur FGFR3 altéré. La construction du réseau de signalisation de FGFR3 via PEPPER donne une vue d’ensemble des voies de signalisation de FGFR3 et ouvre de nouvelles pistes à étudier. / Bladder cancer progression can be divided in two main pathways. The pathway of In Situ Carcinoma (CIS) which progress through an invasion of the basement membrane and then the muscle and the pathway of Ta papillary tumors which change little but recur frequently after tumor resection. Approximately 65% of Ta papillary tumors harboring a FGFR3 mutation and recently FGFR3-TACC3 fusion proteins have been observed in bladder tumors (about 10% of bladder tumors). The oncogenic role of the mutated FGFR3 receptor and of the FGFR3-TACC3 fusion protein has been demonstrated in vivo and in vitro. However signaling pathways activated by the mutated FGFR3 receptor or by the FGFR3-TACC3 fusion protein are currently poorly characterized.In this context, two approaches have been developed to characterize these signaling pathways. The first is based on the study of p38, AKT and ERK1/2 phosphorylation by the mutated receptor (S249C) or the wild type receptor in the NIH3T3 fibroblastic cell line. This study allowed identifying p38 and AKT as activated by the mutated FGFR3 receptor. Moreover, activation of p38 and AKT by the mutated receptor is critical for cell transformation. Study of the activation of these two signaling has been realized in human bladder cancer cell lines endogenously expressing the mutated FGFR3 receptor or the FGFR3-TACC3 fusion protein. Moreover, we showed that p38 and AKT are involved in the maintenance of a FGFR3/MYC feedback positive loop: FGFR3 activation induce MYC over expression which in turns promotes FGFR3 expression. The second approach is based on a study whose aim was to identify FGFR3 proteins partners by mass spectrometry after a FGFR3 immunoprecipitation, which has been previously realized in the lab. Data analyze led to the obtaining of a list of 60 proteins identified has FGFR3 protein partners with a high confidence. Construction of a FGFR3 network with this list was not possible (too little interactions existing between these proteins), so we developed an algorithm (PEPPER) in collaboration with a student in bioinformatics in the lab, Remy Nicolle, to propose a FGFR3 signaling network.The two approaches developed during this thesis allowed us to better characterize the FGFR3 signaling pathways. Identification of a FGFR3/MYC feedback loop allowed us to better understand why the altered FGFR3 has oncogenic properties and to propose p38 and AKT as news promising therapeutic targets, to treat human bladder tumors harboring the altered FGFR3 receptor. Construction of the FGFR3 signaling network with the algorithme PEPPER give an overview of the FGFR3 signaling pathways and open new tracks to explore.

Background: Prostate cancer is the most common cancer in Sweden with around 10,000 new cases every year. Kidney and bladder cancer are less common with 1,000 and 2,000 new cases annually, respectively. The incidence of these cancer sites is higher in developed, than in developing countries, suggesting an association between lifestyle and cancer risk. The aims of this thesis were to investigate body mass index (BMI), blood pressure, and blood levels of glucose, total cholesterol, and triglycerides as risk factors for prostate, kidney, and bladder cancer. Furthermore, we aimed at assess probabilities of prostate cancer and competing events, all-cause death, for men with normal and high levels of metabolic factors. Material and methods: This thesis was conducted within the Metabolic Syndrome and Cancer project (Me-Can), a pooled cohort study with data from 578,700 participants from Norway, Sweden, and Austria. Data from metabolic factors were prospectively collected at health examinations and linked to the Cancer and Cause of Death registers in each country.  Results: High levels of metabolic factors were not associated with increased risk of prostate cancer, but high levels of BMI and blood pressure were associated with risk of prostate cancer death. The probability of prostate cancer was higher for men with normal levels of metabolic factors compared to men with high levels, but the probability of all-cause death, was higher for men with high levels than for those with normal levels. For both men and women, high levels of metabolic factors were associated with increased risk of kidney cancer (renal cell carcinoma). Furthermore, blood pressure for men and BMI for women were found as independent risk factors of kidney cancer. High blood pressure was associated with an increased risk of bladder cancer for men. Conclusions: High levels of metabolic factors were associated to risk of kidney and bladder cancer and to death from kidney, bladder, and prostate cancer. Compared to men with normal levels, men with high levels of metabolic factors had a decreased probability of prostate cancer but an increased probability of all-cause death. / <p>Ytterligare forskningsfinansiärer: World Cancer Research Fund (2007/09) och Wereld Kanker Onderzoek Fonds (R2010/247)</p> / Me-Can

Electronic medical record databases (e.g. the Clinical Practice Research Datalink, CPRD) are increasingly used in epidemiological research. The CPRD has two formats of data: coded, which is the sole format used in almost all research; and free-text (or ‘hidden’), which may contain much clinical information but is generally unavailable to researchers. This thesis examines the ramifications of omitting free-text records from research. Cases with bladder (n=4,915) or pancreatic (n=3,635) cancer were matched to controls (n=21,718, bladder; n=16,459, pancreas) on age, sex and GP practice. Coded and text-only records of attendance for haematuria, jaundice and abdominal pain in the year before cancer diagnosis were identified. The number of patients whose entire attendance record for a symptom/sign existed solely in the text was quantified. Associations between recording method (coded or text-only) and case/control status were estimated (χ2 test). For each symptom/sign, the positive predictive value (PPV, Bayes' Theorem) and odds ratio (OR, conditional logistic regression) for cancer were estimated before and after supplementation with text-only records. Text-only recording was considerable, with 7,951/20,958 (37%) of symptom records being in that format. For individual patients, text-only recording was more likely in controls (140/336=42%) than cases (556/3,147=18%) for visible haematuria in bladder cancer (χ2 test, p<0.001), and for jaundice (21/31=67% vs 463/1,565=30%, p<0.0001) and abdominal pain (323/1,126=29% vs 397/1,789=22%, p<0.001) in pancreatic cancer. Adding text records reduced PPVs of visible haematuria for bladder cancer from 4.0% (95% CI: 3.5–4.6%) to 2.9% (2.6–3.2%) and of jaundice for pancreatic cancer from 12.8% (7.3–21.6%) to 6.3% (4.5–8.7%). Coded records suggested that non-visible haematuria occurred in 127/4,915 (2.6%) cases, a figure below that generally used for study. Supplementation with text-only records increased this to 312/4,915 (6.4%), permitting the first estimation of its OR (28.0, 95% CI: 20.7–37.9, p<0.0001) and PPV (1.60%, 1.22–2.10%, p<0.0001) for bladder cancer. The results suggest that GPs make strong clinical judgements about the probable significance of symptoms – preferentially coding clinical features they consider significant to a diagnosis, while using text to record those that they think are not.

A maioria (75%) dos CBs são primeiramente diagnosticados como não-músculo invasivos (CBNMIs) nos estádios Ta, T1, e carcinoma in situ (CIS). Atualmente, o tratamento mais utilizado contra CBNMIs envolve a imunoterapia com Bacillus Calmette-Guérin (BCG) associada à ressecção transuretral (RTU). No entanto, a utilização de BCG pode causar graves efeitos colaterais e está associada com uma elevada taxa de recorrência após o tratamento. Por conseguinte, várias abordagens têm sido investigadas, incluindo o desenvolvimento de novas moléculas, assim como a melhoria da terapia com medicamentos convencionalmente utilizados no tratamento de tumores e a incorporação de sistemas de carreamento de fármacos. Considerando o uso de novas moléculas, complexos metálicos derivados de bases de Schiff (BSs) são compostos versáteis que apresentam atividade antitumoral, fornecendo assim novas perspectivas para a terapia do CBNMI. Em relação ao carreamento de fármacos, ao longo dos últimos anos, carreadores lipídicos nanoestruturados (CLNs) têm atraído considerável interesse como veículos alternativos para produtos farmacêuticos antitumorais. Assim, com o intuito de adquirir maior conhecimento a respeito da química dos complexos derivados da BS N-Salicilideno anilina (Salan) e também seus efeitos na progressão do CBNMI, esta tese descreve a síntese e caracterização de complexos N-Salicilideno anilina(níquel) [Salan(Ni)] e N-Salicilideno anilina(platina) [Salan(Pt)]. A estrutura proposta desses compostos foi estabelecida por análise elementar (CHN), FTIR, TG, RMN de 1H e 13C. As atividades citotóxicas dos compostos sintetizados [Salan, NiCl2 e Salan(Ni)] foram avaliadas por ensaio MTT e os dados obtidos indicaram que Salan(Ni) demonstrou atividade citotóxica significativa contra linhagens celulares de leucemia e câncer de fígado. Além disso, neste estudo os efeitos histopatológicos e moleculares dos compostos sintetizados [Salan, Salan(Ni) e Salan(Pt)] foram caracterizados e comparados com o tratamento com BCG em um modelo animal de CBNMI. Os resultados obtidos indicaram que o grupo Salan(Ni): apresentou melhor recuperação histopatológica quando comparado ao grupo Câncer; aumentou os níveis da proteína UPIII; aumentou a expressão dos genes supressores de tumor PTEN e p53; causou inibição da angiogênese devido aos níveis proteicos elevados de endostatina e níveis mais baixos da proteína VEGF. No entanto, durante a instilação dos tratamentos, observou-se a precipitação dos compostos. Então, testes utilizando 2% de DMSO em óleo de milho como veículo para complexos do tipo Salan [Salan(Ni) e Salan(Pt)] foram realizados. Adicionalmente, o complexo Salan(Pt) foi incorporado a um carreador lipídico nanoestruturado (CLN) derivado de murumuru. O CLN carregado com Salan(Pt) [Salan(Pt)-CLN] foi preparado através do sistema de agitação mecânica e apresentou diâmetro médio de 165,4 nm e potencial zeta -34,4 mV. Por fim, os compostos obtidos [Salan(Ni), Salan(Pt), CLN livre, Salan(Pt)-CLN] foram administrados in vivo para avaliar seus efeitos contra CBNMI. A análise histológica revelou que o grupo Salan(Ni) apresentou melhor recuperação histopatológica. Análises de Western blotting (WB) indicaram que os tratamentos com Salan(Ni), Salan(Pt) e Salan(Pt)-CLN provavelmente ativam a via p53 diminuindo os níveis proteicos de Akt e PI3K. Em conclusão, os resultados indicaram que o complexo Salan(Ni) apresentou melhores efeitos na redução da agressividade do CBNMI comparado aos demais complexos e BCG. / Bladder cancer (BC) is the second most common genitourinary malignancy. Most (75%) BCs are non–muscle invasive (NMIBC) at first diagnosis [Ta, T1, and carcinoma in situ (CIS)]. Currently, the most used treatment against NMIBC involves the immunotherapy with BCG (Bacillus Calmette-Guérin) associated with the transurethral resection. However, the use of BCG can cause severe side effects and it is associated with high recurrence rate after treatment. Therefore, several approaches have been investigated, including the development of new molecules and also the improvement of the therapy with drugs conventionally used to treat cancers by using drug delivery systems. Considering the use of new molecules, metal complexes derived from Schiff bases (SBs) are versatile molecules with anticancer activity, providing new perspectives for the therapy of NMIBC. Regarding the drug delivery, over the past few years, nanostructured lipid carriers (NLCs) have been attracting considerable interest as alternative carriers for anticancer pharmaceuticals. Thus, in order to acquire more information about the chemistry of the complexes derived from the SB of N-Salicylidene aniline (Salan), as well as its effects on the progression of NIMBC, the present thesis describes the synthesis and characterization of N-Salicylidene aniline(nickel) [Salan(Ni)] and N-Salicylidene aniline(platinum) [Salan(Pt)] complexes. The proposed structure of these compounds was established by elemental analysis (CHN), FTIR, TG, 1H and 13C NMR. Cytotoxic activities of the synthesized compounds [Salan, NiCl2 and Salan(Ni)] were evaluated by the MTT assay and the obtained data indicated that Salan(Ni) showed significant cytotoxic activity against leukemia and liver cancer cells lines. Furthermore, in this study the histopathological and molecular effects of the synthesized compounds [Salan, Salan(Ni) and Salan(Pt)] were characterized and compared with BCG treatment in an animal model of NMIBC. Our results demonstrated that the Salan(Ni) group: improved histopathological recovery when compared with Cancer group; increased UPIII protein levels; increased expression of tumor suppressors genes PTEN and p53; inhibited of angiogenesis assigned to elevated levels of endostatin and lower levels of VEGF. However, during the instillation of treatments, compounds precipitation were observed. Then, tests using 2% DMSO in corn oil as vehicle for Salan-type complexes [Salan(Ni) and Salan(Pt)] were performed. Additionally, Salan(Pt) complex was incorporated into nanostructured lipid carrier (NLC) derived from murumuru. The NLC loaded with Salan(Pt) [Salan(Pt)-NLC] was prepared by using mechanical agitation method and had an average diameter of 165,4 nm as well as zeta potential of -34,4 mV. Ultimately, the obtained compounds [Salan(Ni), Salan(Pt), free NLC, Salan(Pt)-NLC] were administered in vivo to evaluete their effects against NMIBC. The histological analysis revealed that Salan(Ni) group Abstract MATSUMOTO, M. Y. Tese de Doutorado em Biologia Geral e Aplicada – UNESP – Botucatu showed bestter histopathological recovery. Western blotting (WB) analysis indicated that Salan(Ni), Salan(Pt) and Salan(Pt)-NLC treatments probably activate the p53 pathway by decreasing the protein levels of Akt and PI3K. In conclusion, the results showed the Salan(Ni) has better effects in reduction of NMIBC aggressiveness compared to the other complexes and BCG / 2013/04708-8
