MUSEU BIOTECNOLÓGICO

Este trabalho busca arquitetar um museu biotecnológico na cidade de Videira no estado de Santa Catarina que incentive a educação ambiental, fomente o turismo e desenvolva pesquisas nas áreas da engenharia ambiental. O projeto ocupa uma área de 1442 m2 localizado no Parque da Uva próximo a um populoso bairro e da Universidade. O museu conta com quarto pavimentos sendo um deles subsolo. Houve preocupação com acessibilidade, praça de alimentação, reserva técnica, salas de exposições permanentes, area de ação educativa, isolamento termoacústico e revestimento de madeira plastica. O museu possui uma forma regular e estável transmitindo formalidade. A cor branca que prevalence em quase toda a edificação transmite calma e simplicidade. Os pilotsdão a sensação de liberdade interagindo a construção com o meio

ARHGEF9 disease: Phenotype clarification and genotype-phenotype correlation.

ObjectiveWe aimed to generate a review and description of the phenotypic and genotypic spectra of ARHGEF9 mutations.MethodsPatients with mutations or chromosomal disruptions affecting ARHGEF9 were identified through our clinics and review of the literature. Detailed medical history and examination findings were obtained via a standardized questionnaire, or if this was not possible by reviewing the published phenotypic features.ResultsA total of 18 patients (including 5 females) were identified. Six had de novo, 5 had maternally inherited mutations, and 7 had chromosomal disruptions. All females had strongly skewed X-inactivation in favor of the abnormal X-chromosome. Symptoms presented in early childhood with delayed motor development alone or in combination with seizures. Intellectual disability was severe in most and moderate in patients with milder mutations. Males with severe intellectual disability had severe, often intractable, epilepsy and exhibited a particular facial dysmorphism. Patients with mutations in exon 9 affecting the protein's PH domain did not develop epilepsy.ConclusionsARHGEF9 encodes a crucial neuronal synaptic protein; loss of function of which results in severe intellectual disability, epilepsy, and a particular facial dysmorphism. Loss of only the protein's PH domain function is associated with the absence of epilepsy

This conference is a local event aiming at bringing together the research students, staff and eminent external guests to celebrate Engineering and Computer Science Research at the University of Hertfordshire. The ECS Research Conference aims to showcase the broad landscape of research taking place in the School of Engineering and Computer Science. The 2019 conference was articulated around three topical cross-disciplinary themes: Make and Preserve the Future; Connect the People and Cities; and Protect and Care

Redefining the MED13L syndrome

Congenital cardiac and neurodevelopmental deficits have been recently linked to the mediator complex subunit 13-like protein MED13L, a subunit of the CDK8-associated mediator complex that functions in transcriptional regulation through DNA-binding transcription factors and RNA polymerase II. Heterozygous MED13L variants cause transposition of the great arteries and intellectual disability (ID). Here, we report eight patients with predominantly novel MED13L variants who lack such complex congenital heart malformations. Rather, they depict a syndromic form of ID characterized by facial dysmorphism, ID, speech impairment, motor developmental delay with muscular hypotonia and behavioral difficulties. We thereby define a novel syndrome and significantly broaden the clinical spectrum associated with MED13L variants. A prominent feature of the MED13L neurocognitive presentation is profound language impairment, often in combination with articulatory deficits

Elevated Levels of Rad51 Recombination Protein in Tumor Cells

Rad51 is the key enzyme for homologous recombination, an evolutionarily conserved mechanism for the repair of DNA damage and the generation of genetic diversity. Given the observation that many tumors become resistant to radiation therapy and DNA-damaging chemotherapeutics and also that tumor cell populations can acquire a high number of genetic alterations and then expand clonally, dysfunction of the mammalian Rad51 recombinase could play a major role in the multistep process of tumorigenesis. The data we present provide further strong support for this hypothesis. Using anti-Rad51 immunofluorescence staining, widely different tumor cell lines displayed increased numbers of nuclei with focally concentrated Rad51 protein compared with nonmalignant control cell lines. These nuclear foci are thought to represent a repairosome-type assembly of Rad51 and other proteins required for recombinational DNA repair. By Western blot analyses, the net amount of Rad51 protein was increased 2–7-fold in all tested tumor cell lines. Inhibition of de novo protein synthesis by cycloheximide treatment showed a similar half-life of Rad51 protein in normal and tumor cells. Fluorescence in situ hybridization experiments did not detect Rad51 gene amplifications in tumors. Because Northern blot analysis demonstrated highly elevated Rad51 mRNA levels, we conclude that the increases in Rad51 protein and nuclear foci formation in tumor cells are the result of transcriptional up-regulation

Regulation of the MID1 protein function is fine-tuned by a complex pattern of alternative splicing

Clinical features of Opitz BBB/G syndrome are confined to defects of the developing ventral midline, whereas the causative gene, MID1, is ubiquitously expressed. Therefore, a non-redundant physiological function of the MID1 product appears to be developmentally restricted. Here, we report the identification of several alternative MID1 exons in human, mouse and fugu. We show that splice variants of the MID1 gene that are comparable in terms of function occur in the three organisms, suggesting an important role in the regulation of the MID1 protein function. Accordingly, we observed differential MID1 transcript patterns in a tissue-specific manner by Northern blot and RT-PCR. The identified splice variants cause loss-of-function effects via several mechanisms. Some introduce a stop codon followed by a novel poly(A+) tail, leading to the formation of C-terminally truncated proteins. Dominant negative effects through altered binding to the MID1-interacting protein agr4 in vitro could be demonstrated in a couple of cases. Others carry premature termination codons without poly(A+) tails. These are degraded by nonsense mediated mRNA decay (NMD). Our data reveal a mechanism conserved in human, mouse and fugu that regulates developmentally restricted MID1 activity and suggest NMD to be critical in the translational regulation of a ubiquitously transcribed mRNA

Ca++/CaMKII switches nociceptor-sensitizing stimuli into desensitizing stimuli

Many extracellular factors sensitize nociceptors. Often they act simultaneously and/or sequentially on nociceptive neurons. We investigated if stimulation of the protein kinase C epsilon (PKCe) signaling pathway influences the signaling of a subsequent sensitizing stimulus. Central in activation of PKCs is their transient translocation to cellular membranes. We found in cultured nociceptive neurons that only a first stimulation of the PKCe signaling pathway resulted in PKCe translocation. We identified a novel inhibitory cascade to branch off upstream of PKCe, but downstream of Epac via IP3-induced calcium release. This signaling branch actively inhibited subsequent translocation and even attenuated ongoing translocation. A second sensitizing stimulus was rerouted from the sensitizing to the inhibitory branch of the signaling cascade. Central for the rerouting was cytoplasmic calcium increase and CaMKII activation. Accordingly, in behavioral experiments, activation of calcium stores switched sensitizing substances into desensitizing substances in a CaMKII-dependent manner. This mechanism was also observed by in vivo C-fiber electrophysiology corroborating the peripheral location of the switch. Thus, we conclude that the net effect of signaling in nociceptors is defined by the context of the individual cell's signaling history
