OP0309 Intestinal sclerostin/serotonin axis is modulated by dysbiosis and regulates ilc3 expansion in as patients
2017
Background Sclerostin is an osteocyte-specific factor that binds to low-density lipoprotein receptor-related protein 5 (LRP5) inhibiting the Wnt signaling pathway and possibly contributing to the pathogenesis of Ankylosing spondylitis (AS). Subclinical gut inflammation observed in AS patients is characterized by the presence of dysbiosis and innate immune alterations. In the gut, LRP5 activation by unknown ligands inhibits serotonin production. Serotonin, by inducing glial derived neurotrophic factor (GDNF), controls ILC3 expansion, in the context of glial–ILC3–epithelial cell unit (GIECU). Sclerostin/serotonin axis has been never studied in AS. Objectives Aim of this study was to evaluate …
Understanding the effect of Vitamin D treatment on human uterine leiomyoma growth using in vitro and in vivo models
2019
Los miomas uterinos afectan al 70% de las mujeres en edad reproductiva, empeorando la calidad de vida de muchas de ellas debido a sus síntomas asociados. A pesar de su alta prevalencia no existe ninguna terapia efectiva para reducir el tamaño de éstos mínimamente invasiva y sin efectos secundarios. Aunque la patogénesis de los miomas no se conoce completamente, la correlación entre el déficit de Vitamina D (Vit D) y el riesgo de miomas uterinos, junto sus efectos antiproliferativos descritos en cáncer, apuntaron a la Vit D como una posible opción terapéutica para tratar los miomas uterinos. En este sentido, la acción de la Vit D ha sido ampliamente estudiada en cáncer, demostrando que su ac…
Targeting GSK3 and Associated Signaling Pathways Involved in Cancer
2020
Glycogen synthase kinase 3 (GSK-3) is a serine/threonine (S/T) protein kinase. Although GSK-3 originally was identified to have functions in regulation of glycogen synthase, it was subsequently determined to have roles in multiple normal biochemical processes as well as various disease conditions. GSK-3 is sometimes referred to as a moonlighting protein due to the multiple substrates and processes which it controls. Frequently, when GSK-3 phosphorylates proteins, they are targeted for degradation. GSK-3 is often considered a component of the PI3K/PTEN/AKT/GSK-3/mTORC1 pathway as GSK-3 is frequently phosphorylated by AKT which regulates its inactivation. AKT is often active in human cancer a…
The Export Strategy and SMEs Employment Resilience During Slump Periods
2021
Abstract The Spanish economy was the most hit by the Great Recession. It suffered a greater decrease in the gross domestic product (GDP) (affecting especially internal demand). However, it suffered a greater increase in exports (the so-called Spanish “miracle”). Particularly, Spanish SMEs incorporation into exports has been spectacular since 2008. Further, this has coincided with a huge increase in unemployment. Therefore, our main objective is to investigate the moderating role of exports in job destruction associated with recessive contexts of domestic demand using Spanish manufacturing SMEs as a case study. We obtain for SMEs that export participation helps compensate for the decrease in…
An Approach for Network Outage Detection from Drive-Testing Databases
2012
A data-mining framework for analyzing a cellular network drive testing database is described in this paper. The presented method is designed to detect sleeping base stations, network outage, and change of the dominance areas in a cognitive and self-organizing manner. The essence of the method is to find similarities between periodical network measurements and previously known outage data. For this purpose, diffusion maps dimensionality reduction and nearest neighbor data classification methods are utilized. The method is cognitive because it requires training data for the outage detection. In addition, the method is autonomous because it uses minimization of drive testing (MDT) functionalit…
Relevancia del macrófago como fuente de ligandos WNT en las complicaciones asociadas a la enfermedad de crohn
2019
La fibrosis y las fistulas son complicaciones frecuentes de la enfermedad de Crohn cuya etiopatogenia es desconocida. La cronicidad de la inflamación junto con alteraciones en la reparación tisular tras un daño, se han relacionado con estas complicaciones. Los macrófagos son células del sistema inmunitario innato ampliamente implicadas en la regulación de ambos procesos y como consecuencia en el desarrollo de la fibrosis. Estas células presentan elevada plasticidad y un continuo espectro de fenotipos funcionales que explican la diversidad de funciones que regulan. Recientes estudios han demostrado que los macrófagos, a través de vías de señalización dependientes de Stat6, actúan como fuente…
