we try to use 20ng. But the important part to consider is the molarity of the sample (though with the new flow cells should be less important)

Online (non trovo articoli) si indica un polimorfismo di APOBEC3A responsabile di questo nelle popolazioni dell’Asia (anche noi vi accennavamo nel nostro articolo). Questo polimorfismo è presente solo nel 20% di quelle popolazioni. Un po’ poco per avere un effetto sulla pandemia

In realtà un evento selettivo del genere c’è già ed è il frutto del lavoro dei professionisti che combattono il virus (anche se non causa il collasso mutazionale)
A naso direi che più degli APOBEC in Giappone sta funzionando il sistema sanitario: vaccini, prevenzione, etc.
Replying to @silvoLab @kiki_la_bulla @marco_heffler @lucacozzuto @AurelianoStingi @repubblica @Di_SPACE_Lauro
Perché il collasso mutazionale possa avvenire, dovrebbe essere presente un evento selettivo enorme che agisca su tutti gli individui contemporaneamente.
Qualcosa di simile a quello che succede alle cellule tumorali durante la chemioterapia.

Gli APOBEC possono indurre mutazioni sul virus, ma la loro propagazione nella popolazione è dettata dalle solite regole dell’evoluzione (selezione e genetic drift). Non c’è modo che un virus con un genoma non funzionante soppianti quello normale (e poi si suicidi)
non ho accesso all’articolo ma -dal titolo- sono d’accordo.
Gli APOBEC potrebbero avere un effetto sul decorso del COVID nell’individuo. È tutto da dimostrare, ma plausibile.
Causare l’estinzione del virus nel singolo individuo? Forse nelle fasi iniziali dell’infezione, non oltre

Our paper is out in @Nature! Extrachromosomal DNA molecules huddle together in cancer cells to activate oncogene expression (which we call ecDNA hubs). A great collaboration with @KatieEYost, @HowardYChang, @549nm, Zhe Liu, and others. (1/10) nature.com/articles/s41586-0…

Our study "Individualized VDJ recombination predisposes the available Ig sequence space" is now published in Genome Research 🥳

Congrats @rlyhighvariance et al.!
1/11 Did you ever wonder whether individuals have the same probability of generating a given antibody sequence? Turns out, they do not – not even twins!
We showed that humans – including monozygotic twins – have unique VDJ recombination rules. biorxiv.org/content/10.1101/…

1/Excited to share my first author publication where we create split-engineered base editors (seBEs). Here, we place base editors under the control of a small-molecule to regulate the timing of genome editing and decrease off-target effects. To achieve it: nature.com/articles/s41589-0…
Aside from lamenting time and mental resources wasted when I forgot them, I need examples -possibly life-sciences related- to liven up the talk and convince them that choosing the right positive/negative controls is not magic.
I just volunteered to tell 1st year PhD students of the importance of controls in a scientist’s life.
Question for scientists on twitter: can you tell me of egregious cases where the lack of a single control changed completely the story and doomed a published paper forever?
Hopefully, one step closer to the clinic…
It was exciting working on it: methylation, fragmentomics, and all.
Thanks @benbfly and all others!
Just a teaser: the correlation of methylation and tumour fraction (healthy controls are the blue bubbles).

Excited to announce our new preprint on Nanopore methylation for liquid biopsy. Thanks for producing these amazing sequences Filippo, @silvoLab and @nanopore, and thanks to the analysis team Efrat and @ShariO_51. Excellent team effort. @The__Taybor said to get cracking so we did!

Accepted manuscript strongly suggesting that apparent SARS-CoV-2 reads that appear to be integrated in the human genome, are in fact an artefact of library preparation.

your paper is always the first one I cite when I write of APOBECs and cancer :)
2004 - should I start feeling old?
One of the most inspiring, as a person and as a scientist. A huge loss indeed. I will miss him

Do you want to explore basic research but also clinical practice? The IRCM's Master's degree in cellular and molecular medicine (MCM) is for you! ircm.qc.ca/en/studies-and-tr…
This is going to be useful!
Thanks!

Final days to apply for a PhD in my lab. The science is interesting and the lab is welcoming. Of course you will also need to deal with the whole ugly Firenze thing on the side...
Interested in targeting cancer through RNA editing? We have an opening for a PhD student in the #MSCA #ITN ROPES project. Contact me if interested. Deadline 16/04.
