Повний текст джерелаLa aneuploidía, que se define como un número de cromosomas diferente al haploide, es una característica muy común en cáncer ya que se encuentra en alrededor de 68% de los tumores sólidos. Esta resulta en un desequilibrio metabólico que compromete la función celular induciendo estrés proteotóxico y afectando el crecimiento celular, dando lugar a así a una transformación maligna de estas células. Sin embargo, muchos de los mecanismos moleculares detrás de esta transformación generada por la aneuploidía son aún desconocidos. En este trabajo, usamos el epitelio del ala de Drosophila como tejido modelo para demostrar la contribución de la aneuploidía al crecimiento tumoral. Mediante la inhibición de genes del checkpoint del huso mitótico, inducimos inestabilidad cromosómica y aneuploidía que, tras bloquear la muerte celular, da lugar a un sobrecrecimiento tumoral. Cuando las células no tienen aún altos niveles de aneuploidía, activan bajos niveles de la quinasa c-Jun N-terminal (JNK) y activan la respuesta a daño en el DNA (DDR). Esto induce un arresto temporal en G1 que previene la acumulación de más daño. Sin embargo, debido a la inestabilidad cromosómica, estas células continúan proliferando y acumulan altos niveles de aneuploidía, delaminan del epitelio y adquieren un comportamiento senescente. Este depende de la activación de altos niveles de JNK y la DDR y tiene como consecuencia la secreción de distintos factores (SASP) y un arresto permanente en G2, entre otras características senescentes. Además, hemos podido identificar dos factores involucrados en el arresto, Tribbles and String, que podrían actuar en respuesta a JNK y a la DDR para hacer efectivo el arresto en G2. Finalmente, exploramos dos maneras distintas de afectar los tumores CIN aprovechando que sufren daño en el DNA: genéticamente (mediante la sobre-expresión de CycE/Dap) y químicamente (mediante el tratamiento con hidroxiurea), afectando ambas el crecimiento del tejido e inhibiendo la progresión tumoral.

Inspired by the undulating patterns found in different plant and biological cells in nature, this thesis explores the deformation-induced wrinkling instability transformation in the microstructure of composites with thin interfacial layers. The hybrid microstructure of a composite material has an essential influence on the effective properties and behavior of the composite. Hence, in this research, the principles and mechanics of interfacial layer instabilities are purposely designed to achieve sudden pattern transformations in the composite structure to generate new controlled multifunctional behavior. The wrinkling instability transformation is investigated in multilayered and networked composites consisting of relatively stiff interfacial layers or cells embedded in a soft matrix. Through analytical modeling, finite element simulations, and physical experiments, a comprehensive study is performed to elucidate: i) the conditions governing wrinkling, ii) the effect of wrinkling on local deformations, iii) the energy stored and dissipated in wrinkling composites, and iv) the change in the effective mechanical behavior of the composites. It is concluded that these properties are directly dependent on the composite's material and geometrical properties, and that composites can be designed to exhibit enhanced energy absorption (including energy storage and dissipation), stress mitigation effects, bilinear and multi-linear elastic stress-strain behavior, switchable effective stiffness, and can be used for energy harvesting applications. Design guidelines are presented to assist the process of deploying instability-transformation to tune, control, and switch the mechanical properties of multifunctional composite materials. Instability principles such as buckling and wrinkling are favorable mechanisms as they can be designed to be elastic and therefore reversible. The ability to alter and transform the microstructure enables on-demand tunability and active control of the composite's properties and attributes.

Повний текст джерелаLes cèl·lules mare pluripotents induïdes (iPSC) es poden derivar de cèl·lules somàtiques adultes mitjançant la reprogramació amb Oct4, Sox2, Klf4 i c-Myc. Les iPSC han donat lloc a una nova tecnologia per estudiar i tractar malalties humanes (Takahashi et al., 2007). No obstant, abans de la aplicació clínica de les iPSC, dos problemes principals han de ser adreçats: (i) Estabilitat genètica de les iPSC. (ii) Resposta immune de les cèl·lules derivades de iPSC. Per adreçar aquests dos qüestions cabdals, la missió principal d’aquest doctorat és avançar la tecnologia de les iPSC adreçant dos objectius. El primer, és la substitució de c-Myc per Ciclina D1 al còctel de reprogramació (Oct4, Sox2, Klf4 and c-Myc o Ciclina D1) i segon, estudiar la resposta immune de les cèl·lules derivades de iPSC. Hem escollit Ciclina D1 per substituir c-Myc atès a observacions prèvies que pot ser emprat per reprogramar (Edel et al., 2010) i donada la seva funció en reparació de l’ADN (Chalermrujinanant et al., 2016). Les iPSC reprogramades amb Ciclina D1 presenten una pluripotència similar a les reprogramades amb c-Myc, l’anàlisi en profunditat mostra però, que les iPSC reprogramades amb Cyclin D1 tenen una reduïda inestabilitat genètica adreçada per: (i) reducció en ruptures de doble cadena de DNA, (ii) major quantitat nuclear de la proteïna clau en la recombinació homòloga Rad51, (iii) reducció en senyals multitelomèriques (MTS) i (iv) reducció en la cinètica de creixement de teratomes in vivo, en comparació amb iPSC reprogramades amb c-Myc. A més a més, demostrem que les cèl·lules mare neuronals derivades d’aquestes iPSC son capaces de implantar-se exitosament, sobreviure a llarg termini i diferenciar a neurones madures sense evidències de patologia en un model de dany medul·lar. També hem realitzat un anàlisi del sistema immune innat i adaptatiu de cèl·lules humanes de la pell (nomenades F1) reprogramades a iPSC i comparades amb cèl·lules derivades de iPSC (nomenades F2). Hem descobert una isoforma curta del Toll-Like Receptor 3 (TLR3), essencial en el reconeixement de RNA de doble cadena d’origen víric, que està predominantment sobreexpresada en totes les cèl·lules derivades de iPSC analitzades i no trobat en cèl·lules endògenes. Nosaltres proposem un nou model per el qual la isoforma curta del TLR3 competeix amb la isoforma llarga wild type desestabilitzant el procés essencial de dimerització del TLR3.

Unwanted deposition of cells on wetted solids, so-called biofouling, is a serious operational and environmental threat in many underwater and biomedical applications. Over the last decade, Lubricant-Impregnated Surfaces (LIS) has been one of the popular remedies, owing to its unique oil layer that separates solid from cellular media giving no chance for cells to foul. However, a critical bottleneck to this solution has been that retention of the oil could never be permanent, which shortened its anti-fouling efficacy. While understanding the root cause of this oil loss significantly helps prevent such failure, the loss mechanism has not received much attention to date. In this study, we show that secretion of biomolecules from aquatic cells and subsequent change in interfacial tension of the surrounding media can delaminate the oil film, resulting in gradual deterioration of anti-biofouling capability of LIS. We establish a correlation between the decrease in interfacial tension and observed wetting transitions of LIS over the fouling test period. We also visualize the cell medium - oil interface to confirm final wetting states of LIS in situ. We further measure mobility of various algae droplets on such surfaces and scale forces to confirm presence of line force specific to each wetting state. Finally, we propose a LIS regime map that helps determine the design of LIS that can resist oil loss in aquatic cellular environments, increasing long-term anti-biofouling efficacy.

Повний текст джерелаAn in-line square array with pitch-to-diameter ratio P/d = l.5 has been tested in both water- (with low mass ratio, $m/pd sp2$ = 6.5) and air-flow (with high mass ratio, $m/pd sp2$ = 860). The effect of fluidelastic coupling between cylinders on the critical flow velocity for fluidelastic instability was investigated via frequency detuning experiments, including an extreme case of one flexible cylinder in an otherwise rigid cylinder array. The water tunnel experimental results showed that fluidelastic coupling between cylinders in water-flow has little effect on the critical flow velocity for fluidelastic instability, whereas the wind tunnel experimental results demonstrated that fluidelastic coupling between cylinders in airflow has a significant effect on the critical flow velocity. Therefore, for the cases with low mass ratio parameter the negative fluid damping mechanism dominated the fluidelastic instability of the array; however, for cases with high mass ratio, fluidelastic instability of the array was controlled by fluid stiffness effects.
An in-line square array with P/d = l.5 was also tested in the wind tunnel, with cylinders with high and low levels of mechanical damping. The experimental results showed that fluidelastic coupling between cylinders with low mechanical damping has a more significant effect on the critical flow velocity for fluidelastic instability than with high mechanical damping in airflow (with high mass ratio, $m/pd sp2$ = 860); hence, fluid stiffness-controlled mechanism becomes more important for fluidelastic instability of the array with low mechanical damping in airflow. Next, an in-line square array with P/d = 3.0 was tested in the wind tunnel. The results showed that one flexible cylinder becomes unstable when positioned in row 2 of the array; however, it does not become unstable when positioned in rows 3 or 4. This suggests that P/d has a large effect on fluidelastic instability behaviour of in-line square arrays.
Finally, a new constrained-mode approach, with a one-cylinder-kernel, has been developed for the instability analysis of both in-line and staggered arrays. The approach was developed to reduce the computational effort when a fully flexible cylinder array has to be analyzed, in order to take into account fluidelastic coupling; between cylinders.
