Resumen
Au cours des temps géologiques, la vie s'est grandement complexifiée et a connu de nombreuses et importantes variations de biodiversité. Parmi les déclins du Phanérozoïque (-541.0 ± 1.0 Ma à actuel), cinq grandes crises sont considérées comme majeures. L'une d'elles, appelée événement Kellwasser, marque la limite entre le Frasnien et le Famennien (-372 ± 1.6 Ma). Elle est suivie à la transition Dévonien-Carbonifère par un second événement de premier ordre, appelé événement Hangenberg. Ces événements de nature anoxique auraient été déclenchés par les importants changements climatiques caractéri

Based on extended research on Chinese medical and epidemiological archival material dating back to the beginning of the 20th century, and on six months of internship in epidemiology in Beijing’s Medical School and in Haidian District’s Centre of Disease Control and Prevention, this thesis explores the conjunction of three major epidemiological crises in modern Chinese history with processes of State formation: the 1911 Manchurian pneumonic plague, the 1952 germ-warfare, and the 2003 SARS outbreak.

Denna kandidatuppsats gör en ansats till att belysa biodiversitetsproblematiken i Sydostasien, som är ett område med mycket hög artrikedom som samtidigt hotas av en intensifierad förlust av arter. Fyra ’biodiversitet hotspots’ omger Sydostasien, vilka indikerar platser med hög artrikedom vilka sammanfaller med hög förlust av habitat. Det största orsaken till förlust av biologisk mångfald i Sydostasien är omvandlingen utav artrika naturtyper till monokulturodlingar, och expansionen av jordbruk och urbana områden.

Resumen
Epilepsy is a chronic neurological disease characterized by recurrent, unprovoked seizures. Evidence suggests that inflammation plays a role in the pathophysiology of seizures. Although cysteinyl leukotrienes (CysLTs) have been implicated in seizures, no study has investigated whether blocking of CysLT1 receptors potentiates the anticonvulsant action of classic antiepileptic drugs, as well as the expression of CysLT receptors is altered by inflammation. In this study we showed that the inverse agonist of CysLT1 receptor, montelukast, synergistically increases the anticonvulsant action of pheno

Resumen
The recent advances in molecular and computational biology have made possible the study of complicated transcriptional regulatory networks that control a wide range of biological processes and phenotypic traits. In this thesis, several approaches were combined including next generation sequencing, gene expression profiling, chromatin and RNA immunoprecipitation, bioinformatics and genome editing methods in order to characterize the biological significance of the ZBED6 and ZC3H11A genes. A mutation in the binding site of ZBED6, located in an intron of IGF2, disrupts the binding and leads to 3-f

Resumen
CRISPR-Cas9 är ett effektivt genredigeringsverktyg som har upptäckts på senare år. Verktyget härstammar från ett adaptivt immunförsvar hos prokaryoter. Tekniken används för att modifiera DNA hos växter, djur och människor på ett enkelt och billigt sätt. CRISPR-Cas9 har visat sig ha stor potential vid bekämpning av olika sjukdomar däribland cancer som idag är ett globalt hälsoproblem. Inom cancerforskningen ses CRISPR-Cas9 som ett lovande verktyg vid cancerterapi och läkemedelsutveckling. I denna studie sammanställer vi aktuella metoder och användningsområden med CRISPR-Cas9 inom cancerforsknin

Background: Although the large number of studies investigating BRCA mutations and their clinical role in different populations and ethnicities, there is a lack of a systematic analysis on these alterations in Italian cohorts, including the analysis of Variants of Unknown biological and clinical Significance (VUS).

Resumen
Our group previously demonstrated that when a DNA double-strand break (DSB) occurs, RNA polymerase II (RNAPII) is recruited to the exposed DNA ends and allows the by-directional synthesis of transcripts derived from exposed DNA ends that we called damage-induced long non-coding RNAs (dilncRNAs). Recently we reported that a DSB also recruits the full transcriptional machinery, in particular the preinitiation complex (PIC), just as commonly recruited at canonical RNA polymerase II-driven transcriptional promoters. This, blurs the distinction between a DSB and a transcriptional promoter. dilncRN

Resumen
Spider silk has received significant attention due to its fascinating mechanical properties. Given the solitary and cannibalistic behavior of spiders, spider silk farming is impractical. Unlike spiders, silkworms are capable of producing large quantities of a fibrous product in a manner mimetic to spiders, and there already exists an industry to process cocoons into threads and textiles for many applications. The combination of silk farming (sericulture), a millennia old practice, and modern advancements in genetic engineering has given rise to an innovative biomaterial inspired by nature; tra

One of the major limits of current therapies against cancer and viral infections is the nonspecific toxicity that they often cause on healthy tissues because of their impact on important cellular mechanisms shared, to different extents, between diseased and healthy cells. For this reason, there is an unmet need for more specific and more effective therapies. Wherefore, the aim of my project is the development of a novel strategy, with potential for therapy, that allows the induction of sequence-specific DNA lesions (DNA double-strand break, DSB), by the use of the CRISPR/Cas9 system targ

Resumen
Sarcoglycanopathy is the collective name of four rare autosomal recessive diseases belonging to the limb-girdle muscular dystrophies type 2 (LGMD2C-F), due to mutations in SGCG, SGCA, SGCB, SGCD genes coding for γ-, α-, β- and δ- sarcoglycan (SG) respectively. SGs form a tetrameric sub-complex on the sarcolemma, closely linked to the dystrophin associated protein complex (DAPC) and play an essential role in assuring membrane integrity during muscle contraction (Bushby, 2009). Mutations in each SG gene cause the loss/reduction of the mutated protein as well as of the wild type (WT) partners wit

MiRNAs are a class of small non-coding RNAs that function in post-transcriptional gene silencing by interacting with target RNAs. A novel mechanism in control of miRNA levels, called Target-Directed miRNA degradation (TDMD), has been described, which involves specific transcripts able to interact with miRNAs and induce miRNA degradation. We showed that an endogenous RNA transcript, Serpine1, uses TDMD to control levels and activity of miR:30b/c in murine fibroblasts. It is unknown how many other TDMD transcripts exist; therefore, we developed TDMDfinder, a computational pipeline and free webto

In tumors, the reciprocal communication between malignant cells and non-transformed stromal cells involves a variety of signaling proteins and modulators that cooperate to control proliferation, migration and apoptosis.

Accordingly, the loss of DAB2IP in tumor cells fosters metastasis and enhances chemo- and radio-resistance. DAB2IP is rarely mutated in cancer but is frequently downregula
