A simple protein-DNA interaction analysis has been developed using both a high-affinity/high-specificity zinc finger protein and a low-specificity zinc finger protein with nonspecific DNA binding capability. The latter protein is designed to mimic background binding by proteins generated in randomized or shuffled gene libraries. In essence, DNA is immobilized onto the surface of microplate wells via streptavidin capture, and green fluorescent protein (GFP)-labeled protein is added in solution as part of a crude cell lysate or protein mixture. After incubation and washing, bound protein is detected in a standard microplate reader. The minimum sensitivity of the assay is approximately 0.4 nM protein. The assay format is ideally suited to investigate the interactions of DNA binding proteins from within crude cell extracts and/or mixtures of proteins that may be encountered in protein libraries generated by codon randomization or gene shuffling.

El proyecto tipográfico del irlandés Albert O’Farail se concibió como un libro misionero destinado a la empresa confesional que la monarquía de España desarrollaba en las Islas Británicas desde comienzos del Seiscientos. Las traducciones de distintos tratados doctrinales y teológicos, representados por su devoción particular a la Virgen María, procuraban acercar la religión a los católicos del Norte a través de mecanismos de proximidad cultural como complemento a la predicación de los ministros espirituales patrocinados por Carlos II. El empeño por dar a las prensas esta miscelánea de obras, financiada por la corona y compuesta por el arte de su propio autor, discurrió en paralelo a la querella abierta por su esposa, María Manuela Laínez, para reivindicar sus derechos nobiliarios al título marquesal de Mayo. Tanto en Madrid como en Roma, la imbricación de ambos negociados determinó su malograda resolución.

[es] Se establece aquí una relación entre dos obras narrativas publicadas durante los años posteriores a la Segunda Guerra Mundial: El hombre perdido (1947), de Ramón Gómez de la Serna, y La chute (1956), de Albert Camus. Se establece la relación en el plano del pensamiento filosófico y político y se señalan las coincidencias entre las obras. La ciudad, el paseante solitario, el distanciamiento del «gregarismo» y la defensa del individuo coinciden con un leitmotiv, el suicidio, que se da insistentemente en los años cuarenta como consecuencia del desasosiego contemporáneo, la guerra, el nazismo y el totalitarismo socialista impuesto en la URSS, defendido en numerosos núcleos de intelectuales europeos y americanos. [en] This article deals with the connection between two prose works published during the years after World War ii: El hombre perdido (1947) by Ramón Gómez de la Serna and La chute (1956) by Albert Camus. The article examines the relationship from a philosophical and political perspective and establishes the coincidences in both writers’ works. The city, the solitary stroller, the distance from «gregariousness» and the defense of the individual coincide with a leitmotiv, suicide, which has been insistently present during the 1940s as a consequence of contemporary unease, war, Nazism and the socialist totalitarianism imposed on the USSR and supported by many European and American intellectual groups.

In this study, 103 unrelated South-American patients with mucopolysaccharidosis type II (MPS II) were investigated aiming at the identification of iduronate-2-sulfatase (IDS) disease causing mutations and the possibility of some insights on the genotype-phenotype correlation The strategy used for genotyping involved the identification of the previously reported inversion/disruption of the IDS gene by PCR and screening for other mutations by PCR/SSCP. The exons with altered mobility on SSCP were sequenced, as well as all the exons of patients with no SSCP alteration. By using this strategy, we were able to find the pathogenic mutation in all patients. Alterations such as inversion/disruption and partial/total deletions of the IDS gene were found in 20/103 (19%) patients. Small insertions/deletions/indels (<22 bp) and point mutations were identified in 83/103 (88%) patients, including 30 novel mutations; except for a higher frequency of small duplications in relation to small deletions, the frequencies of major and minor alterations found in our sample are in accordance with those described in the literature.

Sickle cell disease (SCD) pathogenesis leads to recurrent vaso-occlusive and hemolytic processes, causing numerous clinical complications including renal damage. As vasoconstrictive mechanisms may be enhanced in SCD, due to endothelial dysfunction and vasoactive protein production, we aimed to determine whether the expression of proteins of the renin-angiotensin system (RAS) may be altered in an animal model of SCD. Plasma angiotensin II (Ang II) was measured in C57BL/6 (WT) mice and mice with SCD by ELISA, while quantitative PCR was used to compare the expressions of the genes encoding the angiotensin-II-receptors 1 and 2 (AT1R and AT2R) and the angiotensin-converting enzymes (ACE1 and ACE2) in the kidneys, hearts, livers and brains of mice. The effects of hydroxyurea (HU; 50-75mg/kg/day, 4weeks) treatment on these parameters were also determined. Plasma Ang II was significantly diminished in SCD mice, compared with WT mice, in association with decreased AT1R and ACE1 expressions in SCD mice kidneys. Treatment of SCD mice with HU reduced leukocyte and platelet counts and increased plasma Ang II to levels similar to those of WT mice. HU also increased AT1R and ACE2 gene expression in the kidney and heart. Results indicate an imbalanced RAS in an SCD mouse model; HU therapy may be able to restore some RAS parameters in these mice. Further investigations regarding Ang II production and the RAS in human SCD may be warranted, as such changes may reflect or contribute to renal damage and alterations in blood pressure.

A monomeric basic PLA2 (PhTX-II) of 14149.08 Da molecular weight was purified to homogeneity from Porthidium hyoprora venom. Amino acid sequence by in tandem mass spectrometry revealed that PhTX-II belongs to Asp49 PLA2 enzyme class and displays conserved domains as the catalytic network, Ca2+-binding loop and the hydrophobic channel of access to the catalytic site, reflected in the high catalytic activity displayed by the enzyme. Moreover, PhTX-II PLA2 showed an allosteric behavior and its enzymatic activity was dependent on Ca2+. Examination of PhTX-II PLA2 by CD spectroscopy indicated a high content of alpha-helical structures, similar to the known structure of secreted phospholipase IIA group suggesting a similar folding. PhTX-II PLA2 causes neuromuscular blockade in avian neuromuscular preparations with a significant direct action on skeletal muscle function, as well as, induced local edema and myotoxicity, in mice. The treatment of PhTX-II by BPB resulted in complete loss of their catalytic activity that was accompanied by loss of their edematogenic effect. On the other hand, enzymatic activity of PhTX-II contributes to this neuromuscular blockade and local myotoxicity is dependent not only on enzymatic activity. These results show that PhTX-II is a myotoxic Asp49 PLA2 that contributes with toxic actions caused by P. hyoprora venom.
