Ultra-conserved elements provide insights to the biogeographic patterns of three benthic macroinvertebrate species in the Baltic Sea
2022
The Baltic Sea, with its steep salinity gradient, high water retention time, and relatively young age, represents a marginal ecosystem between marine and freshwater extremes. Due to differing invasion history and dispersal capabilities of Baltic species, there are large differences in species distributions, species-specific genetic structure and variation, and edge populations that may represent both a subset of the original population, as well as unique genetic lineages. We used a phylogenomic approach to investigate relationships between populations of three benthic macroinvertebrate species: Pygospio elegans, Corophium volutator, and Mya arenaria, providing new insight into evolutionary …
Antigüedad clásica y cultura nobiliaria en la España de finales del siglo XVIII. Autores y ediciones greco-romanas en la biblioteca de José Alvarez d…
2019
This article analyzes the reception of the classical world in the Spanish nobiliary culture at the end of the 18th century. Our objective is materialized through the study of the Greco-Roman books present in the unpublished catalog of the library of José Álvarez de Toledo, 11th Marqués de villafranca. From the examination of the authors and the different editions conserved by the aristocrat, the work tries to examine the influence of the classical world and its actuality in the development of the most advanced nobiliary culture of eighteenth- century Spain.

Production and characterisation of recombinant forms of human pulmonary surfactant protein C (SP-C):Structure and surface activity
2006
Udgivelsesdato: 2006-Apr Surfactant protein C (SP-C) is an essential component for the surface tension-lowering activity of the pulmonary surfactant system. It contains a valine-rich alpha helix that spans the lipid bilayer, and is one of the most hydrophobic proteins known so far. SP-C is also an essential component of various surfactant preparations of animal origin currently used to treat neonatal respiratory distress syndrome (NRDS) in preterm infants. The limited supply of this material and the risk of transmission of infectious agents and immunological reactions have prompted the development of synthetic SP-C-derived peptides or recombinant humanized SP-C for inclusion in new prepar…
A urochordate putative homolog of human EB1, the protein which binds APC1
1996
Abstract The human EB1 protein has been cloned by virtue of its interaction with the C-terminus of the APC (adenomatous polyposis coli) protein, whose C-terminal truncated forms have been shown to accompany sporadic and familial forms of colorectal cancer. We have cloned a putative EB1 homolog from Botryllus schlosseri (Urochordata, Ascidiacea). The deduced protein is 287 amino acids long, and is identical with 48% of the residues in human EB1 and 24–25% in two yeast hypothetical proteins. We propose that such a high degree of conservation among EB1 homologs is indicative of an essential regulatory mechanism in eukaryotic cells.
Two Enhancers Control Transcription of Drosophila muscleblind in the Embryonic Somatic Musculature and in the Central Nervous System
2014
The phylogenetically conserved family of Muscleblind proteins are RNA-binding factors involved in a variety of gene expression processes including alternative splicing regulation, RNA stability and subcellular localization, and miRNA biogenesis, which typically contribute to cell-type specific differentiation. In humans, sequestration of Muscleblind-like proteins MBNL1 and MBNL2 has been implicated in degenerative disorders, particularly expansion diseases such as myotonic dystrophy type 1 and 2. Drosophila muscleblind was previously shown to be expressed in embryonic somatic and visceral muscle subtypes, and in the central nervous system, and to depend on Mef2 for transcriptional activatio…
RPGR ORF15 isoform co-localizes with RPGRIP1 at centrioles and basal bodies and interacts with nucleophosmin
2005
The ORF15 isoform of RPGR (RPGR(ORF15)) and RPGR interacting protein 1 (RPGRIP1) are mutated in a variety of retinal dystrophies but their functions are poorly understood. Here, we show that in cultured mammalian cells both RPGR(ORF15) and RPGRIP1 localize to centrioles. These localizations are resistant to the microtubule destabilizing drug nocodazole and persist throughout the cell cycle. RPGR and RPGRIP1 also co-localize at basal bodies in cells with primary cilia. The C-terminal (C2) domain of RPGR(ORF15) (ORF15(C2)) is highly conserved across 13 mammalian species, suggesting that it is a functionally important domain. Using matrix-assisted laser desorption ionization time-of-flight mas…
The nucleosome remodeling factor ISWI functionally interacts with an evolutionarily conserved network of cellular factors
2010
Abstract ISWI is an evolutionarily conserved ATP-dependent chromatin remodeling factor playing central roles in DNA replication, RNA transcription, and chromosome organization. The variety of biological functions dependent on ISWI suggests that its activity could be highly regulated. Our group has previously isolated and characterized new cellular activities that positively regulate ISWI in Drosophila melanogaster. To identify factors that antagonize ISWI activity we developed a novel in vivo eye-based assay to screen for genetic suppressors of ISWI. Our screen revealed that ISWI interacts with an evolutionarily conserved network of cellular and nuclear factors that escaped previous genetic…

Detailed characterization of human Mycobacterium tuberculosis specific HLA-E restricted CD8+TÂ cells
2018
HLA-E presented antigens are interesting targets for vaccination given HLA-Esâ essentially monomorphic nature. We have shown previously that Mycobacterium tuberculosis (Mtb) peptides are presented by HLA-E to CD8+effector TÂ cells, but the precise phenotype and functional capacity of these cells remains poorly characterized. We have developed and utilized in this study a new protocol combining HLA-E tetramer with intracellular staining for cytokines, transcription factors and cytotoxic molecules to characterize these cells in depth. We confirm in this study the significantly increased ex vivo frequency of Mtb-peptide/HLA-E-TM+CD8+TÂ cells in the circulation of patients with active tubercu…
