N-(2-methyl-indol-1H-5-yl)-1-naphthalenesulfonamide : a novel reversible antimitotic agent inhibiting cancer cell motility

2016

Este es el post-print que se ha publicado de forma definitiva en: https://www.sciencedirect.com/science/article/abs/pii/S0006295216301423 A series of compounds containing the sulfonamide scaffold were synthesized and screened for their in vitro anticancer activity against a representative panel of human cancer cell lines, leading to the identification of N-(2-methyl-1H-indol-5-yl)-1-naphthalenesulfonamide (8e) as a compound showing a remarkable activity across the panel, with IC50 values in the nanomolar-to-low micromolar range. Cell cycle distribution analysis revealed that 8e promoted a severe G2/M arrest, which was followed by cellular senescence as indicated by the detection of senescen…

Hereditary Leiomyomatosis and Renal Cell Cancer Syndrome in Spain: Clinical and Genetic Characterization

2020

Simple Summary Hereditary leiomyomatosis and renal cell cancer (HLRCC) syndrome is a very rare hereditary disorder characterized by cutaneous leiomyomas (CLMs), uterine leiomyomas (ULMs), renal cysts (RCys) and renal cell cancer (RCC), with no data on its prevalence worldwide. No genotype-phenotype associations have been described. The aim of our study was to describe the genotypic and phenotypic features of the largest series of patients with HLRCC from Spain reported to date. Of 27 FH germline pathogenic variants, 12 were not previously reported in databases. Patients with missense pathogenic variants showed higher frequencies of CLMs, ULMs and RCys, than those with loss-of-function varia…

Long-Term in vivo Evaluation of Orthotypical and Heterotypical Bioengineered Human Corneas.

2020

Purpose: Human cornea substitutes generated by tissue engineering currently require limbal stem cells for the generation of orthotypical epithelial cell cultures. We recently reported that bioengineered corneas can be fabricated in vitro from a heterotypical source obtained from Wharton’s jelly in the human umbilical cord (HWJSC). Methods: Here, we generated a partial thickness cornea model based on plastic compression nanostructured fibrin-agarose biomaterials with cornea epithelial cells on top, as an orthotypical model (HOC), or with HWJSC, as a heterotypical model (HHC), and determined their potential in vivo usefulness by implantation in an animal model. Results: No major side effects …

Human Mesenchymal Stem Cells Prevent Neurological Complications of Radiotherapy

2019

Radiotherapy is a highly effective tool for the treatment of brain cancer. However, radiation also causes detrimental effects in the healthy tissue, leading to neurocognitive sequelae that compromise the quality of life of brain cancer patients. Despite the recognition of this serious complication, no satisfactory solutions exist at present. Here we investigated the effects of intranasal administration of human mesenchymal stem cells (hMSCs) as a neuroprotective strategy for cranial radiation in mice. Our results demonstrated that intranasally delivered hMSCs promote radiation-induced brain injury repair, improving neurological function. This intervention confers protection against inflamma…

Estudio de la quiescencia y activación de las células madre neurales adultas por uniones adherentes: papel de la N-cadherina.

2017

El descubrimiento de poblaciones de células madre en el cerebro adulto (NSCs) de los mamíferos ha cambiado nuestra visión del sistema nervioso, añadiendo el concepto de plasticidad celular al de plasticidad neural. El conocimiento detallado de los mecanismos que permiten a las NSCs mantenerse indiferenciadas, dividirse de manera asimétrica para auto-perpetuarse mientras generan progenie diferenciada, y activarse para proliferar contribuyendo así a la renovación de ciertas poblaciones de neuronas durante toda la vida se ha convertido en un campo de investigación en continuo avance. El desarrollo de técnicas que permiten la posibilidad de expandir las NSCs in vitro y de estudiarlas en su micr…

Identificación y caracterización de precursores mesodérmicos con capacidad hematopoyética en el tejido adiposo humano

2013

La fracción vascular estromal (FVE) del tejido adiposo humano contiene precursores mesodérmicos con capacidad de generar in vitro unidades formadoras de colonias hematopoyéticas (CFUs) y colonias mixtas de células hematopoyéticas y endoteliales. El trabajo realizado en esta tesis doctoral ha tenido como objetivo el estudio de estos progenitores hematopoyéticos. Para ello, se aislaron las diferentes subpoblaciones celulares que componen la FVE y tras su caracterización inmunofenotípica, se determinó su capacidad formadora de CFUs y la expresión de los principales factores de transcripción implicados en la hematopoyesis. Para estimar la ontogenia de los progenitores hematopoyéticos contenidos…

Modulação gênica em embriões humanos

2018

O recente implemento de moderna tecnologia -CRISPR/Cas9- possibilitou o avanço inquestionável da edição gênica em linhagem germinativa humana, seja por meio da manipulação de células precursoras de gametas, células tronco pluripotentes, gametas ou, até mesmo, de embriões. Mesmo levando em conta os benefícios terapêuticos preventivos demonstrados nas pesquisas básicas e préclínicas em embriões humanos, tais investigações encontram barreiras de aceitação em todo o mundo. Tal situação exige mudança de atitude no sentido de incrementar o debate em torno da aplicabilidade dessas novas tecnologias. Assim, a adequação das atuais regulamentações faz-se necessária e deve incluir a superação dos desa…

Estudio de la actividad del plasma frío a presión atmosférica sobre el biofilm y células planctónicas de Staphylococcus aureus, Pseudomonas aeruginos…

2020

El objeto de esta tesis es estudiar la actividad del plasma frío a presión atmosférica o ANTP (Atmospheric Non Thermal Plasma) sobre el biofilm y las células planctónicas de Staphylococcus aureus, Pseudomonas aeruginosa y Candida albicans. El plasma constituye el cuarto estado de agregación de la materia, tras los sólidos, líquidos y gases. Se produce al ionizar total o parcialmente un gas, pudiendo utilizar cualquier fuente de energía para su generación (eléctrica, térmica, óptica o radiación electromagnética ionizante). Al producirse cargas eléctricas libres (electrones e iones) el plasma es un buen conductor de la electricidad. El estado de plasma se alcanza cuando buena parte de las par…
