Inhibition der Signaltransduktion des epidermalen Wachstumsfaktorrezeptors (EGF-Rezeptor) durch Peptid-Aptamere : ein neuer Ansatz zur Krebstherapie

Rezeptortyrosinkinasen der Familie der epidermalen Wachstumsfaktorrezeptoren (EGFR) sind in vielen Krebsarten dereguliert und ursächlich an der malignen Transformation beteiligt. Da die Aktivierung vom Rezeptor ausgehender Signaltransduktionskaskaden auf spezifischen Protein-Protein-Interaktionen basiert, kann durch gezielte Interferenz mit diesen Interaktionen das proliferative Signal ausgeschaltet und das Tumorwachstum angehalten werden. Für diese gezielte Interferenz wurde in der vorliegenden Arbeit das Peptid-Aptamer-System eingesetzt, mittels dem Peptide, die in ein Gerüstprotein inseriert sind, aufgrund ihrer Affinität zu einem Zielprotein selektiert werden können. Drei Peptid-Aptamere (KDI1, KDI3, KDI4), die spezifisch mit dem EGF-Rezeptor interagieren, konnten isoliert werden. lntrazelluläre Expression von Peptid-Aptamer KDI1 oder Einbringung des bakteriell exprimierten Peptid-Aptamers KDI1 mittels einer Proteintransduktionsdomäne führte zu reduzierter EGF-abhängiger Proliferation und Transformation. Durch Interferenz des Aptamers mit dem EGF-Rezeptor war die EGF-induzierte Phosphorylierung von Tyrosin 845, 1068 und 1148, sowie die Aktivierung von p46 Shc und STAT3 reduziert. Daher wurde gefolgert, dass das Peptid-Aptamer die EGF-abhängige Rekrutierung der zytoplasmatischen Kinase c-Src an den Rezeptor inhibiert. Durch Fusion einer zusätzlichen Domäne wie der SOCS-Box-Domäne konnte den Peptid-Aptameren eine zusätzliche inhibitorische Funktion gegeben werden. Hierbei handelt es sich um eine Domäne, die spezifisch Kontakt mit E3-Ubiquitin-Ligasen aufbauen kann. Es konnte gezeigt werden, dass durch Transduktion eines solchen Peptid-Aptamers der Rezeptor spezifisch ubiquitinyliert und damit degradiert wird. Das Peptid-Aptamer-System eignet sich somit dazu, Inhibitoren für vorgegebene Zielmoleküle zu isolieren, die sowohl in der Grundlagenforschung als auch in der Tumortherapie Anwendung finden können

La necesidad de regular los puertos privados que presten servicios públicos

Actualmente, la Ley del Sistema Portuario Nacional (LSPN) y su Reglamento (RLSPN) contemplan dos modalidades de inversión privada en infraestructura portuaria para la atención de carga de terceros. La primera se encuentra dentro del régimen de asociaciones público privadas y en el Perú únicamente se ha presentado a través de la figura de las concesiones. La segunda modalidad se refiere al régimen de autorizaciones administrativas y se ha presentado en el Perú esencialmente para la implementación de puertos privados de uso privado. Estas modalidades se diferencian básicamente en: los requisitos necesarios para obtener el título habilitante (contrato de concesión vs. licencia portuaria); las obligaciones que asume el operador portuario frente al Estado peruano; el régimen de penalidades/sancionador al que se sujetan; y las inversiones que se encuentran obligados a efectuar. El objeto de la investigación está estrechamente vinculado a los puertos privados marítimos y a los servicios que éstos prestan a terceros no vinculados. De acuerdo con la Resolución de Acuerdo de Directorio No. 080-2017-APN/DIR, existen 59 terminales portuarios de ámbito marítimo, de los cuales, 33 son de titularidad privada de uso privado. A través de este trabajo hemos tenido una aproximación de cuántos de estos puertos prestan servicios a terceros no vinculados así como el volumen de carga que transportan a través de éstos

The left frontal cortex supports reserve in aging by enhancing functional network efficiency

Background: Recent evidence from fMRI studies suggests that functional hubs, i.e. highly connected brain regions, are important for mental health. We found recently that global connectivity of a hub in the left frontal cortex (LFC-connectivity) is associated with relatively preserved memory abilities and higher levels of protective factors (education, IQ) in normal aging and Alzheimer’s disease. These results suggest that LFC-connectivity supports reserve capacity alleviating memory decline. An open question is, however, why LFC-connectivity is beneficial and supports memory function in the face of neurodegeneration. We hypothesized that higher LFCconnectivity is associated with enhanced efficiency in connected major networks involved in episodic memory. We further hypothesized that higher LFC-related network efficiency predicts higher memory abilities. Methods: We assessed fMRI during a face-name association learning task in 26 healthy cognitively normal elderly participants. Using beta-series correlation analysis, we computed task-related LFC-connectivity to key memory networks including the default-mode network (DMN) and dorsal attention network (DAN). Network efficiency within the DMN and DAN was estimated by the graph theoretical small-worldness statistic. We applied linear regression analyses in order to test the association between LFC-connectivity to the DMN/DAN and small-worldness of these networks. Mediation analysis was applied to test LFC-connectivity to the DMN and DAN as a mediator of the association between education and higher DMN and DAN smallworldness. Lastly, we tested network small-worldness as a predictor of memory performance. Results: We found that higher LFC-connectivity to the DMN and DAN during successful memory encoding and recognition was associated with higher small-worldness of those networks. Higher task-related LFC-connectivity mediated the association between education and higher small-worldness in the DMN and DAN. Further, higher small-worldness of these networks predicted better performance in the memory task. Conclusions: The current results suggest that higher education-related LFC-connectivity to key memory networks during a memory task is associated with higher network efficiency and thus enhanced reserve of memory abilities in aging

A large scale hearing loss screen reveals an extensive unexplored genetic landscape for auditory dysfunction

The developmental and physiological complexity of the auditory system is likely reflected in the underlying set of genes involved in auditory function. In humans, over 150 non-syndromic loci have been identified, and there are more than 400 human genetic syndromes with a hearing loss component. Over 100 non-syndromic hearing loss genes have been identified in mouse and human, but we remain ignorant of the full extent of the genetic landscape involved in auditory dysfunction. As part of the International Mouse Phenotyping Consortium, we undertook a hearing loss screen in a cohort of 3006 mouse knockout strains. In total, we identify 67 candidate hearing loss genes. We detect known hearing loss genes, but the vast majority, 52, of the candidate genes were novel. Our analysis reveals a large and unexplored genetic landscape involved with auditory function

PAX2 Regulates ADAM10 Expression and Mediates Anchorage-Independent Cell Growth of Melanoma Cells

PAX transcription factors play an important role during development and carcinogenesis. In this study, we investigated PAX2 protein levels in melanocytes and melanoma cells by Western Blot and immunofluorescence analysis and characterized the role of PAX2 in the pathogenesis of melanoma. In vitro we found weak PAX2 protein expression in keratinocytes and melanocytes. Compared to melanocytes increased PAX2 protein levels were detectable in melanoma cell lines. Interestingly, in tissue sections of melanoma patients nuclear PAX2 expression strongly correlated with nuclear atypia and the degree of prominent nucleoli, indicating an association of PAX2 with a more atypical cellular phenotype. In addition, with chromatin immunoprecipitation assay, PAX2 overexpression and PAX2 siRNA we present compelling evidence that PAX2 can regulate ADAM10 expression, a metalloproteinase known to play important roles in melanoma metastasis. In human tissue samples we found co-expression of PAX2 and ADAM10 in melanocytes of benign nevi and in melanoma cells of patients with malignant melanoma. Importantly, the downregulation of PAX2 by specific siRNA inhibited the anchorage independent cell growth and decreased the migratory and invasive capacity of melanoma cells. Furthermore, the downregulation of PAX2 abrogated the chemoresistance of melanoma cells against cisplatin, indicating that PAX2 expression mediates cell survival and plays important roles during melanoma progression

Resting-State Connectivity of the Left Frontal Cortex to the Default Mode and Dorsal Attention Network Supports Reserve in Mild Cognitive Impairment

Reserve refers to the phenomenon of relatively preserved cognition in disproportion to the extent of neuropathology, e.g., in Alzheimer’s disease. A putative functional neural substrate underlying reserve is global functional connectivity of the left lateral frontal cortex (LFC, Brodmann Area 6/44). Resting-state fMRI-assessed global LFC-connectivity is associated with protective factors (education) and better maintenance of memory in mild cognitive impairment (MCI). Since the LFC is a hub of the fronto-parietal control network that regulates the activity of other networks, the question arises whether LFC-connectivity to specific networks rather than the whole-brain may underlie reserve. We assessed resting-state fMRI in 24 MCI and 16 healthy controls (HC) and in an independent validation sample (23 MCI/32 HC). Seed-based LFC-connectivity to seven major resting-state networks (i.e., fronto-parietal, limbic, dorsal-attention, somatomotor, default-mode, ventral-attention, visual) was computed, reserve was quantified as residualized memory performance after accounting for age and hippocampal atrophy. In both samples of MCI, LFC-activity was anti-correlated with the default-mode network (DMN), but positively correlated with the dorsal-attention network (DAN). Greater education predicted stronger LFC-DMN-connectivity (anti-correlation) and LFC-DAN-connectivity. Stronger LFC-DMN and LFC-DAN-connectivity each predicted higher reserve, consistently in both MCI samples. No associations were detected for LFC-connectivity to other networks. These novel results extend our previous findings on global functional connectivity of the LFC, showing that LFC-connectivity specifically to the DAN and DMN, two core memory networks, enhances reserve in the memory domain in MCI

The mammalian gene function resource: the International Knockout Mouse Consortium.

In 2007, the International Knockout Mouse Consortium (IKMC) made the ambitious promise to generate mutations in virtually every protein-coding gene of the mouse genome in a concerted worldwide action. Now, 5 years later, the IKMC members have developed high-throughput gene trapping and, in particular, gene-targeting pipelines and generated more than 17,400 mutant murine embryonic stem (ES) cell clones and more than 1,700 mutant mouse strains, most of them conditional. A common IKMC web portal (www.knockoutmouse.org) has been established, allowing easy access to this unparalleled biological resource. The IKMC materials considerably enhance functional gene annotation of the mammalian genome and will have a major impact on future biomedical research

Poetics/Poelitics of materiality in latin american digital poetry

Este artículo propone leer la poesía digital latinoamericana en vinculación con el acontecimiento poético-político que emerge cuando se considera su materialidad. Dar visibilidad a la materialidad habilita limitar la naturalización de los sentidos que vienen asociados a la cultura digital hegemónica contemporánea. Esto se logra desde procedimientos que ponen de relieve tanto los diversos niveles de materialidad inherentes a cada evento artístico literario digital —materialidad textual de superficie, materialidad relacional de las interfaces tanto de software como de hardware, materialidad del código— como los modos convencionales de ser con y hacer sentido de los entramados técnicos digitales que organizan nuestra vida cotidiana.This paper aims to read Latin American digital poetry in regards to the poetic-political event that emerges whenever its materiality is considered. To make materiality visible enables one to restrict the naturalization of meanings associate with contemporary hegemonic digital culture. This is accomplished through artistic procedures that emphasize, on the one hand, the multiple levels of materiality inherent to digital literary works— surface/textual materiality, software and hardware interface relational materiality, code materiality—and, on the other hand, the conventional ways to interact with and build meaning within the digital space that organize everyday life.Fil: Kozak, Claudia.
