Full textMetabolic reprogramming has been observed in many types of cancer, and it is considered a hallmark of this heterogeneous multifactorial disease. Understanding the mechanisms leading to metabolic rewiring and how these activities promote the activation of cancer's malignant properties can help exploit metabolic alterations for therapeutic benefit. In solid tumors, cancer cells interact with the complex habitat of the tumor microenvironment (TME), which can modulate cancer cells' metabolism and their sensitivity or resistance to drug treatment. Three-dimensional (3D) models, such as spheroids, organoids, and organ-on-chips, are changing the paradigm of preclinical cancer research as they more closely resemble the complex tissue environment and architecture found in tumors in vivo than bidimensional (2D) cell cultures. Therefore, 3D models could potentially improve the robustness and reliability of preclinical research data, reducing the need for animal testing and favoring their transition to clinical practice. In this thesis, we performed a metabolic characterization of luminal (MCF7) and triple-negative (MDAMB231 and SUM159PT) breast cancer cell lines and compared their different response to metabolic perturbations through the evaluation of cell proliferation (in 2D) and spheroid formation ability. The main results of this chapter suggest that nutritional deprivations and pharmacological treatments targeting energetic metabolism have a more significant impact on the proliferation of cells growing in 2D than on spheroid formation (3D). Moreover, the perturbation of glucose metabolism by glucose deprivation and 2-deoxy-glucose treatment showed the most potent effect on the spheroid formation process, severely reducing spheroid vitality and morphology, especially on the highly glycolytic MDAMB231 cell line. Furthermore, we developed a reliable and reproducible workflow for the metabolic analysis of three-dimensional cultures by Seahorse XFe96 technology, an extracellular flux analyzer that simultaneously measures the Oxygen Consumption Rate (OCR) and the Extracellular Acidification Rate (ECAR) of living cells. The optimization of the spheroid formation protocol enabled the production of spheroids highly regular in shape and homogenous in size, dramatically reducing variability in the OCR and ECAR measurements among the experimental technical replicates, both under basal and drug treatment conditions. Furthermore, the normalization on a per-cell basis allowed us to directly compare these metabolic parameters between spheroids of different sizes and between 2D and 3D cultures, revealing that metabolic differences among the studied spheroids are mostly related to the cell line rather than to the size of the spheroid. Finally, we characterized energy metabolism and cellular properties associated with spreading and tumor progression of RT112 and 5637, two cell lines from Grade 2 human bladder cancer. Although the two cell lines displayed distinct metabolic and invasive properties, both exhibited sizable respiration, and the metformin treatment gave a global downregulation of the proliferation, migration, and the ability to form spheroids. Altogether, the findings of this thesis open new research perspectives for identifying novel potential therapeutic targets against cancer, getting closer toward the understanding of cancer metabolic plasticity that can be exploited for developing efficient therapeutic strategies for the treatment of oncologic patients.

Full textNicotinamide N-methyltransferase: a novel diagnostic marker and therapeutic target for bladder urothelial carcinoma. Bladder urothelial carcinoma represents one of the most common urologic malignancies and is a major cause of cancer-related death. Although cystoscopy and urine cytology represent the “gold standard” methods for detection and monitoring of this neoplasm, both procedures have limitations. Therefore, the identification of reliable biomarkers for early and non-invasive detection of bladder cancer are urgently required. The present study is focused on the enzyme nicotinamide N-methyltransferase (NNMT). We first analyzed gene expression profiles of tumor and normal tissue samples obtained from the same patient affected with bladder cancer. The enzyme NNMT was identified as a highly expressed gene in tumor compared with control. Therefore, we evaluated NNMT expression in 28 patients with bladder cancer. NNMT mRNA and protein levels were significantly higher in bladder cancer compared to adjacent normal tissue. In addition, NNMT expression levels were evaluated in urinary exfoliated cells obtained from 55 patients with bladder cancer and 107 healthy donors, using Real-Time PCR. Results showed that urinary NNMT expression was significantly higher in bladder cancer patients compared with controls. Receiver operating characteristic (ROC) analyses revealed the excellent diagnostic accuracy of a urine-based NNMT test and the best cut-off value to discriminate bladder cancer patients from healthy subjects. Data reported in the current study suggest that NNMT could represent a molecular biomarker of bladder cancer and could be used for the development of a urine-based test for the early and non-invasive detection of this tumor.

Full textMundialmente, o cancro da bexiga (CB) é o 7º tipo de cancro mais frequente em homens e o 17 º mais frequente em mulheres. É uma doença com etiologia multifatorial associada a vários agentes ambientais e genéticos, dos quais o tabagismo é o fator de risco mais importante. Os carcinomas uroteliais da bexiga (CUBs) são geralmente superficiais em 70% a 80% dos pacientes e invasores em 20% a 30%. Os CUBs não-invasores têm uma alta taxa de recorrência e progressão e os invasores e metastáticos representam a principal causa de morbidade e mortalidade entre os pacientes com CB. A via fosfatidilinositol-3cinase (PI3K) /AKT (Proteína cinase b) -alvo da rapamicina em mamíferos (m-TOR) é uma importante via envolvida no crescimento celular, tumorogénese, invasão celular e resposta a drogas. Esta via é frequentemente ativada em muitas neoplasias e o descontrolo da sinalização PI3K-AKT-mTOR no CB pode contribuir para o crescimento do tumor, angiogénese e metastização. Neste trabalho, foram estudados 96 casos de tumores diagnosticados como CUBs de vários graus e estádios e foi avaliada a imunoexpressão do phospho-mTOR (Ser2448) e do phospho-S6 (Ser235/236). Em relação à expressão do p-mTOR verificou-se que mais de 50% dos casos de CUB não apresentavam ou apresentavam uma baixa expressão desta proteína sendo que não foi encontrada associação deste com estádio ou grau de diferenciação tumoral. Em relação à proteína p-S6 a sua expressão nos CUB foi igualmente nula ou baixa, no entanto encontrou-se uma associação estatisticamente significativa com o estádio e grau de diferenciação, em duas formas de avaliação qualitativa. Estes dois marcadores imunohistoquímicos, quando analisados em conjunto apresentaram uma correlação positiva moderada nos CUB, no entanto, estudos futuros são necessários para avaliar a sua validade como marcadores biológicos e, eventualmente, alvos terapêuticos. Worldwide, bladder cancer (BC) is the 7th most frequent type of cancer in men and the 17th most common in women. It is a disease with multifactorial etiology associated with multiple genetic and environmental agents, of which smoking is the most important risk factor. The urothelial carcinomas of the bladder (CUBs) are generally superficial in 70% to 80% of patients and invasive in 20% to 30%. The non-invasive CUBs have a high rate of recurrence and progression, and the metastatic and invaders ones are the leading cause of morbidity and mortality among patients with CB. The 3 cinase via phosphatidylinositol PI3K/AKT (cinase protein b) target of rapamycin in mammals (m-TOR) is an important pathway involved in cell growth, tumorigenesis, cell invasion and drug response. This pathway is frequently activated in many tumors and uncontrollable signaling PI3K/AKT/mTOR pathway in BC may contribute to tumor growth, angiogenesis and metastasis. In this study, 96 cases of tumors diagnosed as CUBs of various grades and stages were studied, and it was evaluated the immunoreactivity of phospho-mTOR (Ser2448) and phospho-S6 (Ser235/236). Concerning the p-mTOR expression, it was observed that more than 50% of CUB didn`t express or had a low expression of this protein, and it wasn`t found any association between this and the state or grade of the tumor. In what concerns the p-S6 protein, it was equally low or absent its expression in the CUB, although it was found a statistical association with the state and grade of the tumor, in two forms of qualitative evaluation. When analyzed, together, these two markers presented a positive moderated correlation in the CUB, however future studies are necessary to access its validity as biological markers and, eventually, therapeutic targets.

Full textO carcinoma da bexiga é o quinto tumor maligno mais comum, representando cerca de 3,2% de todos os cancros no mundo. A sua patogénese envolve alterações genéticas somáticas induzidas por agentes carcinogéneos ambientais, tais como o tabaco, as aminas aromáticas ou o arsénio. Apesar da caracterização elaborada dos fatores de risco, o carcinoma da bexiga ainda é um problema epidemiológico importante, cuja incidência continua a aumentar a cada ano. A carcinogénese pode ocorrer através da ativação de protooncogenes ou através da perda de genes supressores de tumor, ambos os quais têm sido documentados no carcinoma urotelial (CUB). O CUB, a forma mais comum de carcinoma da bexiga pode ser não-invasor ou invasor, Apesar do carcinoma da bexiga recidivar frequentemente, apresentam um baixo risco de progressão para a doença invasiva e um prognóstico geral favorável. Em contraste, os CUB invasivos caracterizam-se por serem uma doença agressiva, muitas vezes com uma taxa de sobrevida de 5 anos reduzida, apesar do tratamento com cistectomia radical e quimioterapia adjuvante. Ainda que se tenha evoluído nas estratégias cirúrgicas e quimioterapêuticas, a sobrevida na doença invasiva e metastática não apresentou melhorias significativas nas últimas décadas, desde a introdução do BCG na década de 1970 e do MVAC na década de 1980. Neste contexto urge a necessidade de novos alvos terapêuticos. A proteína alvo da rapamicina nos mamíferos (mTOR) desempenha um papel importante na regulação da tradução de proteínas, crescimento celular e metabolismo. Alterações nesta via de sinalização são comuns no cancro (amplificação/mutação da PI3K, perda de função do PTEN, sobrexpressão do AKT e amplificação/sobrexpressão do S6K1 e eIF4E), e, portanto, o mTOR constitui um alvo terapêutico cada vez mais relevante noâmbito destadoença. A rapamicina e os seus análogos provaram ser benéficos como agentes anticancerígenos, numa ampla gama e ensaios pré-clínicos, isoladamente ou combinados com outros inibidores de outras vias de sinalização, como terapêutica para vários tipos de cancro. No entanto, são necessários mais estudos para validar o mTOR como agente terapêutico para o carcinoma da bexiga. Bladder carcinoma is the fifth most common malignancy, accounting for about 3.2% of all cancers worldwide. Its pathogenesis involves somatic genetic changes induced by environmental carcinogens such as tobacco, aromatic amines or arsenic. Despite the characterization established risk factors, carcinoma of the bladder is still an important epidemiologic problem whose incidence continues to increase every year. Carcinogenesis may occur through activation of protooncogenes or through loss of tu-mor suppressor genes, both of which have been documented in urothelial carcinoma (CUB). CUB, the most common form of bladder carcinoma, is divided into noninvasive and invasive with non-invasive lesions divided into low and high grade. Despite frequente reccurences, these injuries often have a low risk of progression to invasive disease and a generally favorable prognosis. In contrast, the invasive subtipe of CUB is characterized as being an aggressive disease, often with a reduced 5-year survival, de-spite treatment with adjuvant chemotherapy and radical cystectomy. Although its sur-gical and chemotherapeutic strategies have evolved, survival in invasive and metastatic disease showed no significant improvements in the last decades, since the introduction of BCG in the 1970s and in the 1980s MVAC. In this context there is an urgent need for new therapeutic targets. Protein mammalian target of rapamycin (mTOR) plays an important role in the regula-tion of protein translation, cell growth and metabolism. Changes in this signaling path-way are common in cancer (amplification / mutation of PI3K, loss of PTEN function, overexpression of AKT and amplification / overexpression of S6K1 and eIF4E) and thus mTOR is an increasingly important therapeutic target in this disease. Rapamycin and its analogs proved to be beneficial as anticancer agents in a broad range in preclinical trials, alone or combined with other inhibitors of other signaling path-ways, such as therapy for various cancers. However, more studies are needed to validate mTOR as a therapeutic agent for bladder carcinoma.

Full textA caquexia associada ao cancro é uma síndrome multifatorial que representa um grande desafio em oncologia clínica. Esta síndrome é caracterizada por uma perda de peso significativa, principalmente devido ao catabolismo acentuado na massa muscular esquelética e, por isso, tem um impacto negativo na qualidade de vida, na tolerância à terapêutica e no tempo de sobrevivência dos pacientes. A disfunção mitocondrial tem sido sugerida como um evento precoce associado à atrofia muscular induzida pelo cancro. Mais especificamente, o comprometimento do turnover mitocondrial (biogénese, dinâmica e mitofagia), a diminuição da síntese de ATP, aumento do stresse oxidativo e um aumento da suscetibilidade à apoptose parecem mediar a disfunção contrátil e o catabolismo muscular subjacentes à caquexia associada ao cancro. O exercício físico tem vindo a ser estudado como uma abordagem terapêutica, devido aos seus efeitos potencialmente benéficos advindos da adaptação mitocondrial e muscular na caquexia associada ao cancro. No sentido de averiguar o efeito do cancro e do exercício físico terapêutico na adaptação muscular esquelética, foi usado um modelo animal de carcinoma urotelial induzido por exposição a BBN e submetido a 13 semanas de corrida em tapete rolante após o diagnóstico. Constatou-se um decréscimo do peso corporal nos animais expostos a BBN, indicativo de caquexia. Paralelamente, ocorreu uma diminuiçao da área da secção transversal do músculo gastrocnemius e aumento de fibrose intersticial, sugestivos de um perfil inflamatório generalizado e catabolismo muscular, atenuados com a prática de exercício físico. Para além disso, o carcinoma urotelial promoveu a disfunção mitocondrial ao nível do sistema de fosforilação oxidativa, diminuindo a expressão de subunidades dos complexos I e II da OXPHOS e a capacidade de síntese de ATP. Verificou-se de igual modo um comprometimento da biogénese mitocondrial, traduzida por uma redução nos níveis de PGC-1α e Tfam, sem impacto na (auto)mitofagia. O exercício físico realizado após o diagnóstico promoveu o restabelecimento da síntese de ATP e da expressão de subunidades dos complexos I e II da OXPHOS, para além de aumentar os marcadores da biogénese mitocondrial (incluindo a Sirt3), assim como da mitofagia (com envolvimento da Bnip3). Os resultados obtidos indicam que a prática de exercício físico após o diagnóstico promove uma remodelação benéfica ao nível do músculo gastrocnemius por regular a plasticidade mitocondrial nos animais com caquexia associada ao cancro. Deste modo, evidências obtidas no presente estudo suportam a recomendação da prática de exercício físico a pacientes oncológicos.
Cancer cachexia is a multifactorial syndrome that presents a great challenge in clinical oncology. This syndrome is characterized by significant weight loss, mainly due to severe skeletal muscle wasting, which has a negative impact on quality of life, tolerance to treatment and life expectancy of patients. Mitochondrial dysfunction has been suggested as an early event associated with cancer induced muscle atrophy. Specifically, impaired mitochondrial turnover (biogenesis, dynamics and mitophagy), reduced ATP synthesis, higher levels of oxidative stress and higher susceptibility to apoptosis seem to compromise muscle contraction and promote catabolism associated with cancer cachexia. Recently, exercise training has been studied as a therapeutic approach due to its potentially beneficial effects in mitochondrial and muscle adaptation in cancer cachexia. In order to determine the impact of cancer and exercise training in skeletal muscle adaptation, an animal model of bladder cancer induced by exposure to BBN was submitted to 13 weeks of treadmill running after the establishment of the disease. Bladder cancer alone promoted a decrease in total body weight, suggesting the presence of cachexia. At the same time, a reduction in the cross sectional area of gastrocnemius muscle and an increase in interstitial fibrosis were noticed, suggesting an inflammatory profile and catabolism, which were attenuated by exercise training. Moreover, bladder cancer compromised oxidative phosphorylation in muscle mitochondria, reducing the levels of complex I and II OXPHOS subunits and causing impaired ATP synthesis. Mitochondrial biogenesis was reduced, evidenced by lower levels of PGC-1α and Tfam, without impact in (auto)mitophagy. Exercise training promoted the reestablishment of ATP synthesis and the expression of complex I and II OXPHOS subunits, as well as an increase in mitochondrial biogenesis markers (including Sirt3) and mitophagy (through Bnip3). Present data highlight the beneficial effects of endurance exercise on cancer cachexia-related muscle remodeling through the regulation of mitochondrial plasticity. As such, our data support the recommendation of physical activity to cancer patients for the management of cachexia.

Full textIntroduction: Bladder cancer (BC) is the second most common malignancy of the urinary tract, with 386,000 cases estimated and 150,000 deaths in 2011. Urothelial carcinomas (UC) represent 95% of BC cases, and knowledge of the molecular pathways associated with BC carcinogenesis is crucial to identify new diagnostic and prognostic biomarkers, and development of new target molecular therapies. MicroRNAs (miRNAs) are short non-coding RNA molecules that play important roles in the regulation of gene expression by acting directly on mRNAs, leading to either mRNA degradation or inhibition of translation, involved in many physiological and pathological processes, including cancer. Objectives: To characterize miRNAs expression profiles in UC, associating with classic prognostic factors: grade and stage. Moreover, correlate miRNA expression with tumor recurrence and survival. Material and Methods: Fourteen miRNAs (miR-100, miR-10a, miR-21, miR-205, miR-let7c, miR-125b, miR-143, miR-145, miR-221, miR-223, miR-15a, miR-16-1, miR- 199a e miR-452) were isolated from surgical specimens from 60 patients classified in two groups: 30 patients with low-grade non-invasive pTa UC that underwent TURB, 30 with high-grade invasive pT2/pT3 UC underwent radical cystectomy. The control group consists in five normal bladder tissue taken from patients that underwent retropubic prostatectomy to treat benign prostatic hyperplasia (BPH). miRNA processing involved three phases: (1) miRNA extraction by specific kits, (2) cDNA generation (3) miRNA amplification through qRT-PCR. Expression profiles were obtained by relative quantification determined by 2-ct method. Endogenous control were RNU-43 and RNU-48. Statistic tests were used to study the prognostic variables and Kaplan-Meyer curves were constructed to analyze disease-free (DFS) and disease-specific (DSS) survivals. Results: All miRNAs were underexpressed in both groups, except miR-10a in pTa and miR-100, 21 and 205 in pT2/pT3 tumors, that where over-expressed. miR-100, miR-21, miR-10a and miR-205 differentialy expressed in both groups and this differences were statistically significant. The Kaplan-Meyer survival curves showed that higher levels of miR-21 were related to shorter DFS for pTa group. Also, higher levels of miR-10a and miR-145 were associated with shorter DFS and higher levels of miR-10a were also related to shorter DSS in pT2/pT3 group. Conclusions: The majority of miRNA were shown to be underexpressed in bladder UC. miR-100, miR-10a, miR-21 and miR-205 were differentially expressed considering tumor grade and stage. The miRNA profile was able to distinguish pTa low grade and pT2-3 high grade tumors. Higher levels of miR- 21 were related to shorter DFS in pTa, while higher levels of miR-10a were associated with shorter DFS and DSS in pT2-3, high grade UC

Full textThis thesis is a contribution to the study of urothelial carcinoma (UC) in the upper urinary tract and in the bladder. It focuses on the search for diagnostic and prognostic biomarkers in these tumors with potential utility in daily clinical practice. Urothelial carcinoma is a neoplastic disease that originates in the urothelium. The most frequent location is the bladder (90%), followed by the upper urinary tract (5-10%) and finally the urethra (1%). It is the ninth most frequent tumor on a global level, and in the European Union, it is ranked fifth in incidence. Urothelial carcinoma of upper urinary tract is a tumor of poor prognosis. In these patients, survival at 5 years does not reach 50% for those with pT2 and/or pT3 and less than 10% for pT4. Nowadays, pathological stage and histological grade are the most commonly used prognostic factors in clinical practice, although they are insufficient to predict the evolution of the disease in an individualized way, since patients with the same tumor phenotype present different follow up. The gold standard for diagnosis and monitoring of bladder cancer is cystoscopy combined in some cases with urinary cytology. Cystoscopy is an invasive, uncomfortable and painful method for patients. The non-invasive method, cytology, has a low sensitivity, especially in low-grade tumors. Consequently, the identification of biomarkers in UC is of great importance to improve different aspects of their diagnosis, prognosis or prediction of the response to treatments. None of the biomarkers described in recent years has been implemented in daily clinical practice yet. In this thesis, on the one hand, prognostic biomarkers for Upper Tact Urothelial Carcinoma are identified and validated in tissue and in serum and on the other hand, a new gene expression signature with high accuracy for the diagnosis and surveillance of bladder cancer is also described. Finally, the utility of an additional analysis in the follow up of patients with cytology suspicious for UC is investigated.

Resumo: o carcinoma urotelial superficial de bexiga é uma neoplasia que apresenta altas taxas de recorrência, se um tratamento complementar não for associado à ressecção completa do tumor. Dentre as alternativas terapêuticas, o BCG intravesicaltem sido o agente mais utilizado, com a finalidade de prevenir recidivas, progressão e aumentar a taxa de sobrevida dos pacientes com tumor de bexiga. o objetivo desse trabalho foi avaliar a eficácia, a longo prazo, da imunoterapia intravesical com BCG, descrever sua toxicidade, analisar fatores de risco do Carcinoma de Células Transicionais (CCT) superficial, tais como: tamanho tumoral, multifocalidade, estadiamento inicial e presença de carcinoma in situ (CIS), e também, correlacionar esses fatores de risco com recidiva tumoral, progressão histológica e realização de cistectomia radical. Nesse estudo, foram analisados 46 pacientes com diagnóstico de CCT superficial de bexiga e que foram submetidos ao tratamento de imunoterapia intravesical com BCG, no período de junho de 1988 a janeiro de 2000. Vinte e dois pacientes (48%) estavam livres de tumor, após o primeiro ciclo de BCG, 37 pacientes (80%), após o segundo ciclo, 41 pacientes (89%), após o terceiro ciclo, e 42 pacientes (91%), após o quarto ciclo. A taxa total de progressão para doença invasiva foi de 9% (4 pacientes). Complicações severas foram observadas em 4 pacientes (9%): 2 casos de hematúria, 1 de orquiepididimite e 1 de febre por mais de 24 horas. A presença de múltiplas lesões tumorais e o tamanho do tumor não apresentaram correlação com o prognóstico desses pacientes. Os tumores que evoluíram para cistectomia radical apresentaram estadiamentos iniciais PTIG2 ou PTIG3. A presença de carcinoma in situ indicou maior chance de recidiva, progressão e evolução para cistectomia radical. A análise dos resultados permitiu as seguintes conclusões: o BCG apresenta uma boa eficácia no tratamento complementar de CCT superficial; o uso do BCG está associado a um baixo índice de complicações severas; os fatores prognósticos mais importantes, na evolução clínica do tumor de bexiga, são estadiamento, grau histológico e carcinoma in situo
Abstract: The bladder superficial urotelial carcinoma is a neoplasy tOOthas shown high recurrence rates if a complementary treatment is not associated to the thorough resection of such tumor. BCG intravesical has been the most applied agent for the prevention either of the recurrences or progression and also for prolonging life of patients suffering ftom bladder cancer. Goal: Analysing effectiveness of the intravesical immunotherapy with BCG and describing its toxicity in the long termo Also analysing the risk factor of superficial CCT, such as: tumor sÍZe, multiplicity, initial staging and presence of cis, establishing a relationship among tumoral recurrences, histological progression and radical cistectomy. Methods and Material: 46 patients with b1adder superficial CCT diagnosis OOve been analysed prospectively and submitted to intravesical uno therapy treatment with BCG, ftom june 1988 to january 2000. Results: The number of patients without a tumor, afier the fust cycIe of BCG was 22 (48%), afier second was 37 (80%), afier third was 41 (89%), afier the forth was 42 (91%) and the total rate of advancing for invasive diasease was 4 (9%). Serious complications OOvebeen observed in 4 patients (9%). Two cases ofhematuria, 1 case of orchiepididymitis and 1 case of fever for over 24 hours. The presence of multiple tumorallesions and sÍZeof tumors OOd no correlation with the prognosis. Tumors which advanced to radical cistectomy showed initial staging pTIG2 or pTIG3. The presence of carcinoma in situ has indicated a greater chance of recurrences, progression and development to radical cistectomy. Conclusion: BCG has showed a good eifectiveness as a complementary treatment for superficial CCT and also a low toxicity. The most significant prognostic factors on the clinicaldevelopment ofbladder tumor are staging, histological grade and carcinoma in situo
