I tumori neuroblastici periferici (pNT) sono tumori pediatrici solidi estremamente eterogenei responsabili del 15% dei decessi per cancro infantile. In Marocco non sono stati condotti studi epidemiologici, molecolari o biologici su questi tumori, il che ci ha spinto a intraprendere questo lavoro. Abbiamo cercato di esaminare i vari dati clinici e istopatologici relativi ai pNT, nonché l’incidenza, la sopravvivenza e la mortalità di questi tumori. Lo studio molecolare ci ha permesso di stabilire il metodo di ibridazione in situ con fluorescenza (FISH), adottato all’unanimità in tutto il mondo per determinare lo stato di amplificazione del MYCN, un importante fattore prognostico nella scelta della strategia terapeutica appropriata. L’amplificazione del MYCN è stata riscontrata nel 27,8% dei casi di pNT. A sua volta, lo studio dell’espressione del CD44 mediante immunoistochimica (IHC) ha rivelato che questa molecola di adesione cellulare è un forte predittore di metastasi, la cui positività è segno di assenza di invasione tumorale. I risultati complessivi ottenuti attraverso questi studi analitici ed epidemiologici hanno permesso di stabilire alcune associazioni cliniche, istologiche e biologiche e sono stati confrontati con i dati internazionali precedentemente riportati.

  • Viral Replication Complexes
    Viruses are obligate intracellular parasites that need to co-opt a living cell’s machinery for replication. At the heart of the viral replication machinery are the nucleic acid polymerases, which are responsible for efficiently copying the viral genome. This process must often be coordinated with other viral processes, including protein translation and viral packaging. The poly...

    The flaviviruses are composed almost entirely of arthropod-borne viruses, a subset of which are responsible for millions of cases of human disease each year. Among these viruses are dengue virus—a scourge throughout the tropical regions of Asia and the Americas; yellow fever virus—the “original” hemorrhagic fever virus; and the recently emerged Zika virus. While the flaviviruse...

    Lesley J. Rogers / Lesley JRogers
    This edited book brings together research reports on the asymmetry of brain function in various species, including humans, dogs, birds, lizards and bees. As shown in a wide range of species, and, as we now know, not solely in humans, the left and right sides of the brain process information in different ways and control different responses or patterns of behaviour. Since this d...

    Joëlle Roche
    The epithelial-to-mesenchymal transition (EMT) is a highly dynamic process with multiple transitional states, by which epithelial cells can convert into a mesenchymal phenotype. This process involves loss of cellular adhesion and cellular polarity, and an improvement in migratory and invasive properties. It occurs during normal embryonic development, tissue regeneration, organ ...

    There has been an observed decrease in the global mortality from cancer, mostly atributable to improved, particularly early, detection and prevention. For many carcinomas and leukaemias in adults, once the disease has reached a certain stage there are no therapies that are able to erradicate the cancer cells and cure patients. There has been progress in the treatment of acute m...
