Mariotti Genomics Lab

I'm happy to announce that I obtained a tenured position at @geneticsub.bsky.social @biologiaub.bsky.social ! 🧬🎉

calling "Acetylysine" the 21st amino acid is a declaration of war

The iGEM UB team has come back from the competition with amazing results!🥇🤩

The team worked in developing a first prototype of an inducible stop codon readthrough riboswitch in Marco Mariotti's lab, here at @geneticsub.bsky.social 🧬1/2

Barcelona-UB: switch scr (2025) [English] Accessory Video for explanations https://2025.igem.wiki/barcelona-ub/index.html

Skippit fuses a SECIS element (readthrough driver) with a theophylline-binding aptamer, yielding the first readthrough-based riboswitch.
By changing ligand concentration, you can flip between producing the canonical protein isoform or the readthrough isoform:

Barcelona-UB: SCR Translational influence (2025) SCR Translational influence https://2025.igem.wiki/barcelona-ub

The project Skippit uses stop codon readthrough as a synthetic biology control knob. In readthrough, the ribosome occasionally ignores a stop codon and keeps translating — extending the protein instead of terminating it:

Short explanation below 👇

The @geneticsub.bsky.social section, was well represented at #EDRC2025 @edrc2025.bsky.social by Nadia and Marco @mariottilab.bsky.social Sofia @sofiajaraujo.bsky.social and Núria @nuriacorbella.bsky.social @araujolabub.bsky.social and Ivan from the Serras’ lab who presented their results

Loving the #EDRC2025 @edrc2025.bsky.social conference so far! Great science and a terrific community. Tomorrow it's our turn to present: Marco will give a talk at the RNA biology session, while Nadya will present a poster shortly after! ❤️🧬🪰 Come and learn why stop makes sense in Drosophila!

3, 2, 1 and we are on!!! #EDRC2025 is starting! Welcome to our more than 740 participants from more than 40 countries! Thank you to all our sponsors!

Only a few hours left before our meeting starts! Are you travelling to #EDRC2025 now? Let us know by using the oficial #EDRC2025 hashtag!

Trump's Harvard cuts threaten a giant in biomedical research: A database about the tiny fruit fly This spring, the Trump administration rescinded a grant that maintained FlyBase, a pillar of global basic research, as part of its broader $2.2 billion funding cuts at Harvard.

The FlyBase situation has made the national news www.nbcnews.com/science/scie...

Loved it!

Here's an interesting paper @natmethods.nature.com introducing the term "Translon", filling a terminology gap in the field of gene expression. Kudos to Pasha Baranov for leading this initiative and gathering many contributors (including myself) for an healthy discussion on fundamental principles 👏

We had lots of fun at the #FestaCiènciaUB with our workshop on gene expression! It seems participants loved it too ❤️🧬! Thanks to the lab members, including the iGem UB team, and all the organizers of the event 👏

🧬 Un any més, la secció de @geneticsub.bsky.social es suma a la #FestaCiènciaUB amb un munt de tallers que podeu visitar fins demà a la @ub.edu
🎉 No us ho perdeu!

#LaUBDivulga | 🧪 Més de 1.800 infants han visitat l’XI #FestaCiènciaUB i han descobert, de la mà dels investigadors #UB, la recerca que fem a la Universitat.

🤩 I dissabte, 31 de maig, vine amb la família! T’hi esperem de 10:00 a 14:00!

@ubdivulga.bsky.social

Today and tomorrow you will find us at the Science Fest of UB #FestaCiènciaUB ! Come and play to our workshop and learn to decipher the code of life 🧬. Free entrance!

It was my pleasure!

On my way to Sevilla! Looking forward to visiting the @cabd-upo-csic.bsky.social

Interesting large scale study on the thrust on scientist and their role in society around the world.

Note: Spain is by far the European country scoring higher - why this is not translated into better conditions and funding ? - a mistery.

🧬 Our mini-symposium on "New advances in CRISPR-Cas" returns on January 24th at @geneticsub.bsky.social !

It's open for attendance without registration. Talks by Anna Cereseto, @robertasu.bsky.social, Annarita Miccio, and Josep Mª Casacuberta!

Looking forward to this year CRISPR-Cas symposium at @geneticsub.bsky.social ! Don't miss it

We have gathered a starter pack of #GeneticsUB people and labs on @bsky.app We will update it regularly so please follow us for @geneticsub.bsky.social news! @biologiaub.bsky.social @ibub-ub.bsky.social @irbio-ub.bsky.social go.bsky.app/Atuq2VC
