Extracellular vesicles. New endogenous shuttles for mirnas in cancer diagnosis and therapy?
Extracellular Vesicles (EVs) represent a heterogeneous population of membranous cell-derived structures, including cargo-oriented exosomes and microvesicles. EVs are functionally associated with intercellular communication and play an essential role in multiple physiopathological conditions. Shedding of EVs is frequently increased in malignancies and their content, including proteins and nucleic acids, altered during carcinogenesis and cancer progression. EVs-mediated intercellular communication between tumor cells and between tumor and stromal cells can modulate, through cargo miRNA, the survival, progression, and drug resistance in cancer conditions. These consolidated suggestions and EVs’ stability in bodily fluids have led to extensive investigations on the potential employment of circulating EVs-derived miRNAs as tumor biomarkers and potential therapeutic vehicles. In this review, we highlight the current knowledge about circulating EVs-miRNAs in human cancer and the application limits of these tools, discussing their clinical utility and challenges in functions such as in biomarkers and instruments for diagnosis, prognosis, and therapy
Looking for seismites in the Fucino basin: preliminary results from a combined geological geophysical approach.
We present a combined geological-geophysical study on the lacustrine sequence of the Fucino Plain (central Italy). New
acquired data on liquefaction features and the recovery of a seismite in the lacustrine sequence are shown. Our preliminary
results suggest the occurrence of three seismic events in the last ca. 45 kyr. Moreover, a first attempt to find out the source deposit
responsible of the widespread liquefaction phenomena has been performed by means of shallow engine boreholes and ERT
profiles
Composition and stage dynamics of mitochondrial complexes in Plasmodium falciparum
Our current understanding of mitochondrial functioning is largely restricted to traditional model organisms, which only represent a fraction of eukaryotic diversity. The unusual mitochondrion of malaria parasites is a validated drug target but remains poorly understood. Here, we apply complexome profiling to map the inventory of protein complexes across the pathogenic asexual blood stages and the transmissible gametocyte stages of Plasmodium falciparum. We identify remarkably divergent composition and clade-specific additions of all respiratory chain complexes. Furthermore, we show that respiratory chain complex components and linked metabolic pathways are up to 40-fold more prevalent in gametocytes, while glycolytic enzymes are substantially reduced. Underlining this functional switch, we find that cristae are exclusively present in gametocytes. Leveraging these divergent properties and stage dynamics for drug development presents an attractive opportunity to discover novel classes of antimalarials and increase our repertoire of gametocytocidal drugs
Imaging the three-dimensional architecture of the Middle Aterno basin (2009 L’Aquila earthquake, Central Italy) using ground TDEM and seismic noise surveys: preliminary results
We present preliminary results from a multidisciplinary geophysical approach applied to the imaging of the threedimensional
architecture of the Middle Aterno basin, close to the epicentral area of the 2009 L’Aquila earthquake (central Italy).
We collected several time domain electromagnetic soundings (TDEM) coupled with seismic noise measurements focusing on the
characterization of the bedrock/infill interface. Our preliminary results agree with existing geophysical data collected in the area,
and show that the southeastern portion of the basin is characterized by a deepening of the Mesozoic-Tertiary bedrock down to a
depth of more than 450 m. We found that a joint use of electromagnetic and seismic methods significantly contributes in
obtaining new insights on the 3D geometry of the Middle Aterno basin. Moreover, we believe that our combined approach based
on TDEM and noise measurements can be adopted to investigate similar geological settings elsewhere.PublishedPescina (AQ)2T. Tettonica attivaope
