Audero, Madelaine. "Acidic tumor microenvironment and Ca2+ signaling interplay in Pancreatic Ductal Adenocarcinoma (PDAC) progression." Electronic Thesis or Diss., Université de Lille (2022-....), 2023. http://www.theses.fr/2023ULILS105.
Pancreatic ductal adenocarcinoma (PDAC) is the most common cancer affecting the pancreas, characterized by an unsatisfactory 5-year survival rate of around 10%, and to date, there are no effective therapeutic options for PDAC. This is in part due to a highly desmoplastic and immunosuppressive microenvironment that contributes to therapeutic failure. Moreover, the PDAC tumor microenvironment is featured by high acidosis (˂ pHe 6.5), a result of the metabolic reprogramming ("Warburg effect"), and hypoxic conditions, which offers important cues for its aggressiveness by selecting cancer cell phenotypes with competitive benefits for PDAC progression. In this context, Ca2+-permeable ion channels are known to regulate several hallmarks of cancer, including in PDAC. Therefore, they represent good target candidates due to their ability to integrate signals from the TME. Ca2+ channels are indeed pH and hypoxia sensors able to transduce TME signals to activate intracellular downstream pathways linked to PDAC progression. Although the roles of tumor acidosis and Ca2+ signaling in cancer progression are well established, the hypothesis of acidic TME employing Ca2+ signaling as a preferential route for sustaining tumor progression has not yet been sufficiently explored.My Ph.D. work aimed to study the phenotypic and genetic changes of PDAC cells upon acidic stress along the different stages of selection and to evaluate how tumor acidosis modulates Ca2+ signals and phenotypes in the PDAC cell lines, with a particular focus on Ca2+ oscillations and Store-Operated Ca2+ entry (SOCE). To this end, PANC-1 and Mia PaCa-2 cells were subjected to short- and long-term acidic pressure and recovery to pHe 7.4. The latter treatment was to mimic PDAC edges and consequent cancer cell escape from the tumor. The impact of acidosis was assessed for cell morphology, proliferation, adhesion, migration, invasion, invadopodia activity, and epithelial-mesenchymal transition (EMT) via functional in vitro assays and RNA sequencing, and for intracellular Ca2+ signals using Fura-2. Our results indicate that short acidic treatment limits the growth, adhesion, invasion, and viability of PDAC cells. As the acid treatment progresses, it selects cancer cells with enhanced migration and invasion abilities induced by EMT, thereby further enhancing their metastatic potential when re-exposed to pHe 7.4. RNA-seq analysis of PANC-1 cells exposed to short-term acidosis and pHe-selected recovered to pHe 7.4 revealed distinct transcriptome rewiring. We noted an enrichment of genes relevant to proliferation, migration, EMT, and invasion in acid-selected cells. Interestingly, PANC-1 cells are characterized by slower Ca2+ oscillations during short-term acid exposure compared to control cells and a tendency of ORAI1 downregulation at mRNA levels, while long-term acidosis and recovery to neutral pHe determine the recovery of fast Ca2+ oscillations and upregulation of ORAI1. In all our cell models, Ca2+ oscillations are SOCE-dependent, as ORAI1 blockade with Synta66 and siORAI1 results in impaired Ca2+ oscillations' initiation and maintenance. These data correlate with SOCE in PANC-1 cells, which is decreased during the short-term acid treatment, and increased in acid-selected cells with and without recovery to pHe 7.4. Finally, ORAI1-mediated Ca2+ entry might be involved in the activation of signaling cascades that lead to the increased migration and invasion of all the cell models exposed to acidic pHe, as Synta66 treatment and siORAI1 didn't affect control cells' invasion and migration.In conclusion, our findings show that acid-induced selection contributes to the acquisition of a more aggressive phenotype in PDAC cells, characterized by upregulation of SOCE, required for the generation of fast Ca2+ oscillations which may trigger Ca2+-dependent signaling pathways involved in PDAC progression

Neural stem cells (NSC) persist in the brain of adult mammals and fuel the brain with new neurons and glial cells all lifelong. Recruited by brain injuries, NSC are considered with great interest by regenerative medicine. However, the development of new therapeutic approaches based on the use of NSC requires an in-depth knowledge of the mechanism regulating these cells. Glioblastomas are the most frequent and deadliest form of adult brain tumors. Within the tumor, glioblastoma stem cells (GSC) form a subpopulation of cells that is considered as responsible of tumor initiation, propagation and relapse, as these cells are particularly resistant to anti-tumoral treatments. GSC and NSC share key characteristics and numerous studies suggest that GSC arise from transformed NSC. Transcriptomic analysis of NSC and of GSC revealed an enrichment of calcium signaling transcripts in these two cell populations. Representing a major way of calcium influx into cells, Store-Operated Channels (SOC) are mobilized in response to a wide range of extracellular factors. SOC regulate many cellular processes and are often hijacked in cancer to promote tumor progression.The aim of this thesis is to evaluate potential SOC involvement in NSC and GSC regulation.The first part of this work, relying on in vitro and in vivo studies, demonstrates that NSC from adult mice express functional SOC whose inhibition by pharmacological agents reduces NSC proliferation and self-renewal. In the second part of this thesis, we demonstrate that GSC from primary cultures derived from patients express SOC, as do NSC, and that SOC inhibition reduces GSC ability to proliferate and self-renew.Accordingly, the results of this thesis demonstrate that SOC regulate NSC and GSC self-renewal, a property that is essential to maintain stem cells pool. As GSC are responsible for glioblastomas treatment resistance, our studies point to a potential new therapeutic way, via calcium channels, against this deadly pathology

The lipid-binding glycoprotein CD36, expressed by circumvallate papillae (CVP) of the mouse tongue, has been shown to be implicated in oro-gustatory perception of dietary lipids. We demonstrate that linoleic acid (LA) by activating sPLA2, cPLA2 and iPLA2 via CD36, produced arachidonic acid (AA) and lyso-phosphatidylcholine (Lyso-PC) which triggered Ca2+ influx in CD36-positive taste bud cells (TBC), purified from mouse CVP. LA induced the production of Ca2+ influx factor (CIF). CIF, AA and Lyso-PC exerted different actions on the opening of store-operated Ca2+ (SOC) channels, constituted of Orai proteins and regulated by STIM1, a sensor of Ca2+ depletion in the endoplasmic reticulum. We used siRNA technology and transgenic mice models and observed that CIF and Lyso-PC opened Orai1 channels whereas AA-opened Ca2+ channels were composed of Orai1/Orai3. STIM1 was found to regulate LA-induced CIF production and opening of both kinds of Ca2+ channels. Furthermore, Stim1–/– mice lost the spontaneous preference for fat, observed in wild-type animals. The CD36-positive TBC from Stim1–/– mice also failed to release serotonin into extracellular environment. Our results suggest that fatty acid-induced Ca2+ signaling, regulated by STIM1 via CD36, might be implicated in oro-gustatory perception of dietary lipids and the spontaneous preference for fat

A cana-de-açúcar é uma planta C4 que possui boa adaptabilidade em regiões tropicais e subtropicais, em diferentes tipos de solos e condições climáticas, destacando a sua grande importância econômica no cenário mundial atual, por ser matéria prima de produtos como o álcool e o açúcar e subprodutos. A deficiência hídrica é um dos principais fatores que limitam a produção da cana-de-açúcar. O objetivo deste estudo foi caracterizar variedades de cana-soca sob diferentes regimes hídricos no Cerrado brasileiro. O experimento foi conduzido em uma área de 0,36 hectares, localizada na EMBRAPA Cerrados, próxima a Planaltina-DF. O delineamento experimental utilizado foi em blocos ao acaso com três repetições em parcelas subdivididas; cada variedade constituía uma parcela e os diferentes regimes hídricos, irrigado e sequeiro, as subparcelas. No experimento a irrigação foi aplicada conforme o sistema Line Source Sprinkler System, modificado de forma que a lâmina de água aplicada na cultura descresse do centro para as extremidades da área. Foram avaliadas características biométricas: diâmetro médio do colmo (DMC), altura média do perfilho (AMP), número de folhas verdes completamente abertas (NFVA), comprimento e largura da folha +3 (C+3 e L+3, respectivamente), índice de área foliar (IAF) e área foliar (AF); características de produção: produtividade de colmos e qualidade do caldo : comprimento do entrenó (CE), peso do colmo (PC), número de perfilhos por hectare e produtividade; tecnológicos do caldo: ºBrix do caldo, Pol do caldo (teor de sacarose), pureza (PZA), AR (teor de açúcares redutores do caldo), ARC (açúcares redutores da cana), fibras, Pol da cana (PCC), açúcares totais recuperáveis (ATR) e o valor da megagrama da cana (VMgC); e características fisiológicos: prolina livre na folha; e trocas gasosas foliares: transpiração (E), condutância estomática (gs), fotossíntese líquida (A), carboxilação (EC); e aumento da eficiência intrínseca do uso da água (EIUA) e a concentração foliar de clorofilas (a, b e total); Os dados foram submetidos à análise de variância e regressão, e as médias comparadas pelo teste de Tukey a p<0,05. A variedade RB867515 foi a que apresentou maiores valores biométricos de DMC, AMP, C+3 e L+3, tanto em cultivo irrigado como em sequeiro; observou-se que houve redução nos números de NFVA, e aumento do NFE e NFM por perfilhos quando as variedades foram cultivadas em sequeiro; as variedades RB835486 e RB867515 se mostraram melhor adaptadas à restrição hídrica ocorrida até os 137 DAC para os tratamentos em sequeiro. A variedade RB867515 e a RB855156 foram as que obtiveram maior produtividade, com 174,99 e 148,10 Mg ha-1, respectivamente. A cana-de-açúcar cultivada com irrigação equivalente a 75% da ETc não proporcionou diferença significativa para a qualidade industrial das variedades RB835486, RB855156 e RB867515 em relação ao cultivo em sequeiro (0% da ETc). Não houve diferença significativa para os valores do teor de açúcares redutores (AR), açúcares redutores da cana (ARC) e a pureza do caldo (PZA) entre as variedades RB835486, RB855156 e RB867515. As variedades de cana-de-açúcar RB835486, RB855156 e RB867515 cultivadas em sistema de sequeiro apresentaram redução na transpiração (E), condutância estomática (gs), fotossíntese líquida (A), carboxilação (EC), clorofila a (Clo a), clorofila total (Clo a+b); e aumento da eficiência intrínseca do uso da água (EIUA).
The sugarcane is a C4 plant that has good adaptability in tropical and subtropical regions, in different types of soils and climatic conditions, highlighting its great economic importance in the current world scenario, because it is raw material for products such as alcohol and sugar and byproducts. Water stress is a major factor limiting the production of cane sugar. The objective of this study was to characterize ratoon varieties under different water regimes cultived in the Brazilian Cerrado. The experiment was conducted in an area of 0.36 hectares, located in EMBRAPA Cerrado, near Planaltina-DF. The experimental design was a randomized block design with three replications in a split plot; each variety was a plot and the different water regimes, irrigated and rainfed, the subplots. In the experiment the irrigation was applied as Line Source Sprinkler System system, modified so that the amount of water applied to disbelieve culture from the center to the edges of the area. Biometric characteristics were evaluated: average diameter of the stem (DMC), average stem height (AMP), number of wide open green leaves (NFVA), length and width of the sheet +3 (C+3 and L+3, respectively), leaf area index (LAI) and leaf area (LA); production characteristics: sugarcane yield and quality of the broth: length of internode (EC), stem weight (PC), tiller number per hectare productivity; processing the juice: °Brix of the juice, the juice Pol (Sucrose content), purity (PZA), AR (content of reducing sugars of the juice), ARC (reducing sugarcane), fibers, cane Pol (PCC), sugars total recoverable (ATR) and the value of megagram sugarcane (VMgC); and physiological characteristics: free proline in leaf; and leaf gas exchange: transpiration (E), stomatal conductance (gs), net photosynthesis (A), carboxylation (CE); and increased intrinsic water use efficiency (EIUA) and leaf chlorophyll concentration (a, b and total); Data were subjected to analysis of variance and regression and the means compared by Tukey test ap <0.05. The RB867515 variety showed the largest biometric values of DMC, AMP, C+3 and L+3 in both irrigated and rainfed; it was observed that there was a reduction in the number of NFVA and increasing the SNF and NFM per tiller where varieties were grown in upland; the RB835486 and RB867515 varieties proved better suited to water restriction occurred until 137 CAD for treatments in upland. The RB867515 and RB855156 variety were the ones that had higher productivity, with 174.99 and 148.10 Mg ha-1, respectively. The sugarcane grown with irrigation equivalent to 75% of ETc not provided significant difference to the quality of industrial RB835486 varieties, RB855156 and RB867515 concerning cultivation in rainfed (0% ETc). There was no significant difference in the values of reducing sugars (AR), reducing sugarcane (ARC) and the purity of the broth (PZA) between varieties RB835486, RB855156 and RB867515. The varieties of sugarcane RB835486, RB855156 and RB867515 grown in rainfed system had reduced transpiration (E), stomatal conductance (gs), net photosynthesis (A), carboxylation (CE), chlorophyll a (Clo a) chlorophyll (Clo a+b); and increased intrinsic water use efficiency (EIUA).

Irrigation can provide great influence on the productivity of sugarcane, but part of the sugarcane fields under irrigation are still getting inadequate management of varieties and soil. Then, must be identified management that optimize the sugarcane yield and increase the crop longevity. Among these practices, the suitable fertilization after each harvest and the soil management combined with irrigation management, can contribute to increase productivity and longevity of sugarcane crop. Then, this study aimed to evaluate the effects of subsoiling on soil physical attributes with sugarcane growing after two harvests and on the retention water and productivity under nitrogen doses. The treatments were arranged in three blocks randomized with arrangement in split plots, composed of five levels of nitrogen (0, 40, 80, 120 and 160 t.ha-1) with and without subsoiling, being evaluated under rainfed and irrigated conditions resulting in two experiments. Soil physical properties were evaluated on 0-20; 20-40 and 40-60 cm, which are hydraulic conductivity, penetration resistance, bulk density, water retention curve and pore distribution by size. Additionally, some technological quality parameters of sugarcane were determined, as the productivity of stalks (TCH), tons of total reducing sugar per hectare and tons of Pol per hectare. The results were analyzed by F test (ANOVA) and the significant results have evaluated through a comparison of means using the Tukey test, at a level of 5% probability. Regression analysis was used for evaluate nitrogen levels effect. The results showed that subsoiling didn’t increase significantly the water soil retention since total porosity increased only in some layers. The density of the soil subsoiled reduced while, soil hydraulic conductivity increased by 50%, and as a result there was significant reduction in soil penetration resistance values. Among the technological variables, only productivity showed significant gains. The N rates favored a linear increase in productivity. Subsoiling tend to be a promising practice to contribute in maintaining the sugarcane yield after 2nd harvest.
A irrigação pode exercer grande influência sobre a produtividade da cana de açúcar, porém parte dos canaviais cultivados sob irrigação ainda estão recebendo o manejo inadequado das variedades e do solo. Nesse contexto, é necessário que sejam identificadas práticas de manejo que otimizem o rendimento do canavial e aumentem a longevidade da socaria. Dentre essas práticas, a adequação das doses dos nutrientes fornecidos a cultura após cada corte e o manejo do solo pós-colheita aliadas ao manejo da irrigação, podem auxiliar no incremento de produtividade e longevidade do canavial. Assim, o presente trabalho teve como objetivo avaliar os efeitos da subsolagem nos atributos físicos de um solo cultivado com cana de açúcar em 3ª folha irrigada e os reflexos na capacidade de absorção de água e na produtividade, sob doses crescentes de nitrogênio. Os tratamentos foram dispostos em três blocos casualizados com arranjo em parcelas subdivididas, compostos de cinco doses de nitrogênio (0, 40, 80, 120 e 160 t ha-1) em solo com e sem subsolagem, testando-se em condições de sequeiro e irrigado, resultando em dois experimentos. Os atributos físicos do solo foram avaliados nas camadas de 0-20; 20-40 e 40-60 cm, quais sejam, condutividade hidráulica saturada, resistência do solo à penetração, densidade do solo, curva característica de retenção de água no solo e distribuição dos poros por tamanho. Além disso, foram determinados alguns parâmetros de qualidade tecnológica da cana de açúcar, como a produtividade de colmos (TCH), toneladas de ATR por hectare e toneladas de Pol por hectare. Os resultados foram analisados pelo teste F (ANOVA) e os resultados significantes foram analisados pela comparação entre médias usando o teste Tukey, ao nível de 5% de probabilidade. A análise de regressão foi utilizada para avaliar o efeito das doses de nitrogênio. Os resultados indicaram que a subsolagem não promoveu aumento significativo na retenção de água, uma vez que a porosidade total do solo aumentou significativamente apenas em algumas das camadas avaliadas. A densidade do solo subsolado reduziu, enquanto que a condutividade hidráulica do solo aumentou em 50% e consequentemente, houve redução significativa nos valores de resistência do solo à penetração. Entre as variáveis tecnológicas, apenas a produtividade apresentou ganhos significativos. A TCH aumentou nas áreas subsoladas com interação significativa com as doses crescentes de nitrogênio, refletindo em aumento linear de produtividade. A subsolagem nas entrelinhas da soqueira mostrou-se, portanto, como uma promissora prática auxiliar na busca pela manutenção do rendimento do canavial no 3º corte.

In the current context of incessant search for renewable energies, the development of ethanol market has been often discussed at academic scenery, as well as the whole society. Thus, this situation creates room for studies aimed at improve the ethanol agro-industrial chain, even as the upgrading of programs linked with ethanol promotion. Facing it, this thesis makes a comparative analysis between Brazilian and Canadian ethanol markets, using the New Institutional Economics to identify some similarities and differences. In order to reach this goal, three aspects regarding each country are observed: primary information of markets (industrial complex, production, consumption, raw material, production process, automotive fleet and so on), governance structure (hierarchical, hybrid and market) adopted by ethanol plants to manage their agricultural raw material supply chain, and institutional environment where Brazilian and Canadian mills are involved (policies for promotion, protection and regulation of the ethanol market). Regarding the first analyzed item, it is possible to see that Brazil has an ethanol market much more consolidated than Canadian market, although the last one demonstrates potential for growth. Moreover, the ethanol produced by the domestic industry has significant competitive advantage in terms of agricultural/industrial and environmental yield. About the institutional environment, the results show strong intervention of Canadian government in the conducted of domestic ethanol industry, differently what happens in Brazil, where national state has currently made just few interventions on Brazilian ethanol sector. Regarding the third studied element, the governance structure, for Brazil hierarchical structure was identified as predominant, on the other hand hybrid (establishments of purchase and sale contracts with suppliers of agricultural raw material) structure was considered the most common in Canada. Divergence largely explained by the high specificity of sugarcane compared to corn and wheat.

Esta dissertação apresenta uma análise da modelagem de canal sob o desvanecimento κ-μ sombreado com aplicações de segurança na camada física usando o modelo clássico de escuta de Wyner. O modelo κ-μ sombreado foi escolhido por fornecer um modelo geral de desvanecimento e quando comparado a outros modelos de desvanecimento como o Rayleigh, Rice, Nakagami-m e κ-μ, foi encontrado um melhor ajuste utilizando este modelo. Comparações foram feitas utilizando conceitos de Probabilidade de Interrupção de Sigilo (do inglês, Secrecy Outage Probability, SOP), de Capacidade de Sigilo Estritamente Positiva (do inglês, Strictly Positive Secrecy Capacity, SPSC) e Capacidade Média de Sigilo (do inglês, Average Secrecy Capacity, ASC). As formulações fechadas de um caso da SOP e da SPSC foram obtidas e demonstradas. Os resultados e análises são realizados por meio das curvas de SOP, SPSC e ASC, variando as características do canal intruso e do canal principal sob o modelo κ-μ sombreado. Além disso, algumas técnicas de combate ao desvanecimento aplicadas ao canal principal são analisadas como a Combinação Seletiva (do inglês, Selection Combining, SC), a Combinação por Razão Máxima (do inglês, Maximum Ratio Combining, MRC) e a técnica de Múltiplas Entradas e Múltiplas Saídas (do inglês, Multiple-In Multiple-Out, MIMO) com o canal de desvanecimento κ-μ sombreada.
This dissertation presents an analysis of shadowed κ-μ fading channel with security applications at the physical layer using the Wynner’s classic wiretap model. The κ-μ shadowed model was chosen because it provided a general model of fading and when compared to other fading models such as Rayleigh, Rice, Nakagami-m and κ-μ, a better fit was found using this model. Comparisons were made using concepts of Secrecy Outage Probability (SOP), Strictly Positive Secrecy Capacity (SPSC) and Average Secrecy Capacity (ASC). The closed formulations of a case of SOP and SPSC were obtained and demonstrated. The results and analyzes are performed using the SOP, SPSC and ASC curves, varying the characteristics of the intrusion channel and the main channel under the κ-μ shadowed model. In addition, some techniques to combat fading applied to the main channel are analyzed as the Selective Combination (SC), Maximum Ratio Combining (MRC) e Multiple-Input Multiple-Output (MIMO).
