Narcotráfico na metrópole: das redes ilegais à “territorialização perversa” na periferia de Belém

A expansão do crime organizado em escala global, sobretudo, atrelado ao narcotráfico vem contribuindo nos últimos anos para que a Amazônia seja inserida na lógica de organização das redes ilegais. Assim, a sua localização geográfica juntos aos principais produtores de cocaína e ao mesmo tempo a sua proximidade em relação aos mercados da Europa e EUA despertam o interesse da economia do tráfico de drogas. Por outro lado, a droga que atravessa a Amazônia também abastece os mercados locais de suas metrópoles, a exemplo de Belém, aonde o narcotráfico vem se espacializando e se territorializando em áreas periféricas da cidade, envolvendo a metrópole na dinâmica economica da geográfica do crime organizado. Assim, os bairros periféricos do Guamá e da Terra Firme, abarcados pela bacia do Tucunduba, estão envolvidos por uma espécie de territórios-rede em que o tráfico local está associado às redes do tráfico global, e ao mesmo tempo, em escala local, convivem com a presença de territórios-zona, onde o tráfico se fecha para comandar sua atuação. Nesse sentido, a criminalidade vem se expandindo na forma de uma territorialização perversa, pois o tráfico de drogas impõe os seus limites pelo uso força e pela lógica do medo como estratégias de dominação.

The traceability/trackability of illegal trade in whale products: a proposal to evaluate the technical functionality of DNA registers

The Government of Japan, through the Institute for Cetacean Research (Tokyo), has established a DNA register for whales taken under special permit or otherwise destined for commercial markets (IWC 2005; IWC 2010a). The functionality of this DNA register, for the purposes of traceability/trackability, is critical to the current negotiations on the future of the IWC (IWC 2010b). Here we request access to the DNA register for 3 species of whales (fin, sei and Antarctic minke) for the purposes of tracking the origins of whale products purchased at commercial outlets in Seoul, South Korea and Santa Monica, US, as described in the Baker et al. (2010). The attached proposal was included as Supplementary Material to this published article and submitted for consideration to the IWC Data Availability Group (DAG) on 12 April 2010. However, the DAG declined to forward the proposal to the data holders, recommending that we “wait until the Scientific Committee has reviewed the proposed DNA register/market sampling text in the draft Consensus Decision in accordance with the Commission's instructions and then reported to the Commission itself” (email 16 May 2010). We assume that this will take place at SC/62 in Agadir and request that this proposal be considered for endorsement by the DNA subcommittee.

Associations among genotype, clinical phenotype, and intracellular localization of trafficking proteins in ARC syndrome

Arthrogryposisrenal dysfunctioncholestasis (ARC) syndrome is a rare autosomal recessive multisystem disorder caused by mutations in vacuolar protein sorting 33 homologue B (VPS33B) and VPS33B interacting protein, apicalbasolateral polarity regulator (VIPAR). Cardinal features of ARC include congenital joint contractures, renal tubular dysfunction, cholestasis, severe failure to thrive, ichthyosis, and a defect in platelet alpha-granule biogenesis. Most patients with ARC do not survive past the first year of life. We report two patients presenting with a mild ARC phenotype, now 5.5 and 3.5 years old. Both patients were compound heterozygotes with the novel VPS33B donor splice-site mutation c.1225+5G>C in common. Immunoblotting and complementary DNA analysis suggest expression of a shorter VPS33B transcript, and cell-based assays show that c.1225+5G>C VPS33B mutant retains some ability to interact with VIPAR (and thus partial wild-type function). This study provides the first evidence of genotypephenotype correlation in ARC and suggests that VPS33B c.1225+5G>C mutation predicts a mild ARC phenotype. We have established an interactive online database for ARC (https://grenada.lumc.nl/LOVD2/ARC) comprising all known variants in VPS33B and VIPAR. Also included in the database are 15 novel pathogenic variants in VPS33B and five in VIPAR. Hum Mutat 33:16561664, 2012. (c) 2012 Wiley Periodicals, Inc.

T-3 Rapidly Increases SLC2A4 Gene Expression and GLUT4 Trafficking to the Plasma Membrane in Skeletal Muscle of Rat and Improves Glucose Homeostasis

Background: Glucose transporter 4 (GLUT4) is highly expressed in muscle and fat tissue, where triiodothyronine (T-3) induces solute carrier family 2 facilitated glucose transporter member 4 (SLC2A4) gene transcription. T-3 was also shown to rapidly increase glucose uptake in myocytes exposed to cycloheximide, indicating that it might act nongenomically to regulate GLUT4 availability. We tested this hypothesis by evaluating, in thyroidectomized rats (Tx rats), the acute and/or chronic T-3 effects on GLUT4 mRNA expression and polyadenylation, protein content, and trafficking to the plasma membrane (PM) in skeletal muscle, as well as on blood glucose disappearance rate (kITT) after insulin administration. Methods: Rats were surgically thyroidectomized and treated with T-3 (0.3 to 100 mu g/100 g body weight) from 10 minutes to 5 days, and killed thereafter. Sham-operated (SO) rats were used as controls. Total RNA was extracted from the skeletal muscles (soleus [SOL] and extensorum digitalis longus [EDL]) and subjected to Northern blotting analysis using rat GLUT4 cDNA probe. Total protein was extracted and subjected to specific centrifugations for subcellular fractionation, and PM as well as microsomal (M) fractions were subjected to Western blotting analysis, using anti-GLUT4 antiserum as a probe. GLUT4 mRNA polyadenylation was examined by a rapid amplification of cDNA ends-poly(A) test (RACE-PAT). Results: Thyroidectomy reduced skeletal muscle GLUT4 mRNA, mRNA poly(A) tail length, protein content, and trafficking to the PM, as well as the kITT. The acute T-3 treatment rapidly (30 minutes) increased all these parameters compared with Tx rats. The 5-day T-3 treatment increased GLUT4 mRNA and protein expression, and restored GLUT4 trafficking to the PM and kITT to SO values. Conclusions: The results presented here show for the first time that, in parallel to its transcriptional action on the SLC2A4 gene, T-3 exerts a rapid post-transcriptional effect on GLUT4 mRNA polyadenylation, which might increase transcript stability and translation efficiency, leading to the increased GLUT4 content and availability to skeletal muscle, as well as on GLUT4 translocation to the PM, improving the insulin sensitivity, as shown by the kITT.

Polymorphic toxin systems: Comprehensive characterization of trafficking modes, processing, mechanisms of action, immunity and ecology using comparative genomics

Background: Proteinaceous toxins are observed across all levels of inter-organismal and intra-genomic conflicts. These include recently discovered prokaryotic polymorphic toxin systems implicated in intra-specific conflicts. They are characterized by a remarkable diversity of C-terminal toxin domains generated by recombination with standalone toxin-coding cassettes. Prior analysis revealed a striking diversity of nuclease and deaminase domains among the toxin modules. We systematically investigated polymorphic toxin systems using comparative genomics, sequence and structure analysis. Results: Polymorphic toxin systems are distributed across all major bacterial lineages and are delivered by at least eight distinct secretory systems. In addition to type-II, these include type-V, VI, VII (ESX), and the poorly characterized "Photorhabdus virulence cassettes (PVC)", PrsW-dependent and MuF phage-capsid-like systems. We present evidence that trafficking of these toxins is often accompanied by autoproteolytic processing catalyzed by HINT, ZU5, PrsW, caspase-like, papain-like, and a novel metallopeptidase associated with the PVC system. We identified over 150 distinct toxin domains in these systems. These span an extraordinary catalytic spectrum to include 23 distinct clades of peptidases, numerous previously unrecognized versions of nucleases and deaminases, ADP-ribosyltransferases, ADP ribosyl cyclases, RelA/SpoT-like nucleotidyltransferases, glycosyltranferases and other enzymes predicted to modify lipids and carbohydrates, and a pore-forming toxin domain. Several of these toxin domains are shared with host-directed effectors of pathogenic bacteria. Over 90 families of immunity proteins might neutralize anywhere between a single to at least 27 distinct types of toxin domains. In some organisms multiple tandem immunity genes or immunity protein domains are organized into polyimmunity loci or polyimmunity proteins. Gene-neighborhood-analysis of polymorphic toxin systems predicts the presence of novel trafficking-related components, and also the organizational logic that allows toxin diversification through recombination. Domain architecture and protein-length analysis revealed that these toxins might be deployed as secreted factors, through directed injection, or via inter-cellular contact facilitated by filamentous structures formed by RHS/YD, filamentous hemagglutinin and other repeats. Phyletic pattern and life-style analysis indicate that polymorphic toxins and polyimmunity loci participate in cooperative behavior and facultative 'cheating' in several ecosystems such as the human oral cavity and soil. Multiple domains from these systems have also been repeatedly transferred to eukaryotes and their viruses, such as the nucleo-cytoplasmic large DNA viruses. Conclusions: Along with a comprehensive inventory of toxins and immunity proteins, we present several testable predictions regarding active sites and catalytic mechanisms of toxins, their processing and trafficking and their role in intra-specific and inter-specific interactions between bacteria. These systems provide insights regarding the emergence of key systems at different points in eukaryotic evolution, such as ADP ribosylation, interaction of myosin VI with cargo proteins, mediation of apoptosis, hyphal heteroincompatibility, hedgehog signaling, arthropod toxins, cell-cell interaction molecules like teneurins and different signaling messengers.
