Unexpected mutations in gene editing

2022-02-08T18:59:56+01:008 February 2022|Categories: Medicine and Research|Tags: , , |

Many of you will have already heard of CRISPR-Cas9, the so-called molecular scissors that serve to modify the DNA of many organisms. This technique has represented a revolution in the field of genetic engineering in recent years due to its ability to "cut and sew" a specific DNA sequence to make corrections in target genes. So much so that it has opened new avenues and new possibilities for gene therapy, that is, the possibility of treating or preventing diseases by intervening directly on the patient's genome. But how advanced are these techniques today? And what are the risks? The use of CRISPR which created more [...]

How- DNA does -not- change

With the problem of RNA vaccines, fear of changes in our DNA has also risen. What are we really talking about? There is this risk? Let's try to explain it. The structure of DNA is a relatively young discovery, which has less than 70 years. Editing - modification- genica has even fewer years of history behind it, so much so that the most advanced technique that is known won the Nobel only last year. So we can say that the unscientific community, who is not so familiar with these hi-tech stuff, he didn't have much time to understand concepts like genetics, the term [...]

DNA come biomateriale

2021-07-02T16:22:46+02:001 July 2021|Categories: Medicine and Research|Tags: , , , |

Our genetic instructions are invaluable: DNA not only determines who we are, but it can also be used in medicine for gene therapy. It's not all: looking at it from a structural and physical point of view, a team of biotechnologists and materials physicists has developed the so-called "DNA hydrogels", antigenico. These can be used in various biomedical applications: in the formulation of drugs, in gene therapy and cell therapy approaches. DNA as a biomaterial shows qualities such as biocompatibility and biodegradability, that [...]

Stop aging: telomeres as molecular clocks

2021-03-14T13:01:37+01:0025 February 2016|Categories: Medicine and Research|Tags: , , , , |

What determines the aging of an organism? Through what mechanisms it is established? Once the latter are understood, it is possible to stop its progress? Since time immemorial, man has been asking himself similar questions, as numerous as the attempts to arrive at a solution. Magic, alchemy and religion are just some of the means employed over the millennia to attempt to penetrate the secrets of concepts such as eternal youth and immortality. Seduced by the mirage of an unlimited life and the ambition to subjugate time to one's will, our ancestors sought, with the tools at their disposal, to arrive at answers that later proved to be unsuccessful. These ancients [...]

The origin of multicellular life forms

2017-07-12T17:18:04+02:0011 February 2016|Categories: No Category|Tags: , , , , , |

What allowed at the evolutionary level, the appearance of multicellular organisms? This question, remained unsolved for a long time, may have finally found an answer. A recent study has in fact revealed the origin of one of the essential events for the existence of multicellularity: the correct orientation of the mitotic spindle. Let's try to understand what it is. […]

Pollution and fine dust: how to see clearly in the fog of public debate

2017-07-12T17:35:24+02:004 February 2016|Categories: No Category|Tags: , , , , , , , |

Sia che siate lettori attenti all’ attualità oppure semplici cittadini che utilizzano i propri autoveicoli, non vi sarà certamente sfuggita l’attenzione che media, istituzioni e amministrazioni stanno riservando al tema dell’inquinamento urbanistico. Parole come polveri sottili, particolato sospeso o sigle come PM10 sono state ormai del tutto sdoganate dalla loro accezione meramente tecnica e sono diventate di pubblico dominio. Ma a cosa ci si riferisce quando sentiamo questi termini? Provando a fare un po’ di chiarezza potremmo dire che il fulcro del discorso ruota intorno al concetto di particolato sospeso (In inglese “particular matter”, abbreviato con la sigla “PM”), ossia [...]

Gli incroci tra sapiens, neanderthaliani e l’ancora poco nota specie asiatica dei denisoviani, ha portato parte degli europei e degli asiatici moderni a ereditare geni di regolazione per il sistema immunitario derivati dai loro antenati non sapiens. Questi geni possono aver favorito in passato i loro portatori aiutandoli a proteggersi dai microrganismi con risposte immunitarie aggressive, ma sono anche probabilmente responsabili della predisposizione alle allergie di molti degli esseri umani moderni che li esprimono.
