HSP70 gene expression in Mytilus galloprovincialis hemocytes is triggered by moderate heat shock and Vibrio anguillarum, but not by V. splendidus or …
2005
Complete sequence of HSP70 cDNA from the mussel, Mytilus galloprovincialis was established before quantifying its expression following moderate heat shock or injection of heat-killed bacteria. HSP70 cDNA is comprised of 2378 bp including one ORF of 654 aa, with a predicted 70 bp 5'-UTR and a 343 bp 3'-UTR (GenBank, 18 Jan 05, AY861684). Alignment identity ranged from 89% for Crassostrea ariakensis to 72% for C. virginica. Curiously, HSP70 gene and cDNA sequences from M. galloprovincialis, deposited later (03 and 27 May), show only 73% identity with the present sequence. Meanwhile, characteristic motifs of the HSP70 family were located in conserved positions. Expression of HSP70 gene was qua…
Polymorphisms of β-defensin genes in Valle del Belice dairy sheep
2011
The aim of this work was to study β-defensin 1 (SBD1) and β-defensin 2 (SBD2) genes in Valle del Belice dairy sheep in order to identify polymorphisms that can be utilized as markers of the analyzed genes, and search for the functional effects and roles of the identified polymorphisms (variation of the amino acid sequence of the protein and stability of mRNA molecule). The study was conducted on 300 randomly selected animals belonging to four flocks. A total of seven SNPs were identified, two in SBD1 and five in SBD2. The two SNPs identified in SBD2 coding region, at position 1659 and position 1667, were non-synonymous, leading to amino acid changes in the protein product. Nevertheless, the…

Myotonic dystrophy associated expanded CUG repeat muscleblind positive ribonuclear foci are not toxic to Drosophila
2005
Myotonic dystrophy type 1 is an autosomal dominant disorder associated with the expansion of a CTG repeat in the 3 0 untranslated region (UTR) of the DMPK gene. Recent data suggest that pathogenesis is predominantly mediated by a gain of function of the mutant transcript. In patients, these expanded CUG repeat-containing transcripts are sequestered into ribonuclear foci that also contain the muscleblind-like proteins. To provide further insights into muscleblind function and the pathogenesis of myotonic dystrophy, we generated Drosophila incorporating CTG repeats in the 3 0 -UTR of a reporter gene. As in patients, expanded CUG repeats form discrete ribonuclear foci in Drosophila muscle cell…
The pro-opiomelanocortin gene of the zebrafish (Danio rerio)
2003
The cDNA and the gene for pro-opiomelanocortin (POMC) in the zebrafish (Danio rerio) were isolated and analyzed. The gene consists of three exons and two short introns and has a similar overall structural organization as in Homo sapiens. Intron 1 (339 bp) divides the 5(') untranslated region from the coding region while intron 2 (1522 bp) is located between the signal peptide and the sequence encoding ACTH. Transcription starts 26 bp downstream of a TATA box and there is one polyadenylation signal in the 3(') untranslated region. The cDNA comprises of 964 bp with an open reading frame encoding a 222 amino acid hormone prepropeptide that is split into six putative hormones. Sequence comparis…
miR-15a-3p Protects Against Isoniazid-Induced Liver Injury via Suppressing N-Acetyltransferase 2 Expression
2021
Isoniazid (INH), an effective first-line drug for tuberculosis treatment, has been reported to be associated with hepatotoxicity for decades, but the underlying mechanisms are poorly understood. N-acetyltransferase 2 (NAT2) is a Phase II enzyme that specifically catalyzes the acetylation of INH, and NAT2 expression/activity play pivotal roles in INH metabolism, drug efficacy, and toxicity. In this study, we systematically investigated the regulatory roles of microRNA (miRNA) in NAT2 expression and INH-induced liver injury via a series of in silico, in vitro, and in vivo analyses. Four mature miRNAs, including hsa-miR-15a-3p, hsa-miR-628-5p, hsa-miR-1262, and hsa-miR-3132, were predicted to …
Cities and regional disparities in the European Union: evolving geographies and challenges for Cohesion Policy
2021
Since the nineties, urban areas have assumed a growing importance in EU Cohesion Policy. This process, which is being implemented through various political steps and policy instruments, has led cities to be recognised as key elements in the promotion of balanced development. After decades of planning experiments at different territorial scales, however, the extent to which EU urban policy has contributed to regional development is currently under debate. This paper seeks to describe the evolution of the urban dimension within EU Cohesion Policy, with a focus on the role of cities in those countries and regions experiencing development problems.
Understanding urban policy through the lens of twenty years of cohesion policy: the case of Palermo
2017
For many European cities the EU’s structural funds have led to a radical review of the way of approaching urban policy at different scales. For many others, particularly within the less developed regions, they also have resulted in a unique financial opportunity to carry out large infrastructural interventions as well as complex regeneration projects. After two decades of experiments, it is worth questioning to which extent the structural funds have impacted on the state of the European cities and whether Europanisation has promoted a real process of innovation in the making of urban policy. With this question on the background, this paper provides a critical analysis of the evolution of ur…
EU's urban policy from a Southern perspective: the case of Palermo
2017
For many European cities the EU’s structural funds have led to a radical innovation in approaching urban policy at different scales. For many others, particularly within the less developed regions, they also have resulted in a unique financial opportunity to carry out large infrastructural interventions as well as complex regeneration projects. In this context, this paper provides a critical analysis of the evolution of urban policy in the city of Palermo, the fifth Italian city by demographic size and capital of one of the largest less developed region of the European Union. Through the analysis of various initiatives carried out over the last two decades – from the Urban Initiative in the…
