Edda will participate at two upcoming conferences and speak about our work. Please reach out when you are there!

• "The Non-coding Genome” (EMBO/EMBL Symposium) 11–14 Oct 2023 in Heidelberg, Germany.

Diana Mojica and Ingrid Pelaez Conde are starting their PhD project and Heleen Mallie joins us for an internship. Welcome to the team!

Read our work: we used serial perturbations with quantitative mathematical modelling to discover the signaling pathways that regulate differences between stem cells with two (female) and one X-chromosome.

Till presents his work on how two different developmental signals are integrated by TFs and cis-regulatory DNA, at the Xist locus. Meet Till here:

• “16th Berlin Summer Meeting of the Berlin Institute for Medical Systems Biology (BIMSB)”, 6 Sep– 7 Sep 2023 in Berlin, Germany.
• “11th Conference of the German Stem Cell Network (GSCN)”, 13 Sep– 15 Sep 2023 in Ulm, Germany.

The lab is exited about the X-chromosome inactivation meeting, 19-22 June 2023, in Berlin. Edda is co-organizer; the whole lab is assisting, and we are all looking forward to meeting the community!

• Meeting website
• Gemma speaks on Tuesday, Edda on Wednesday, and we present posters: Alex (II-62), Elodie (II-46), Nelly (I-39), and Till (II-70)

CasTuner - our tool to tune endogenous gene expression:
Out in a peer-reviewed version, tested on additional targets, in human cells and on physiological phenotypes.

• Blog post “behind the paper”: here.

Reach out to Gemma Noviello at the
“EMBO workshop: Systems biology: Linking chromatin and epigenetics to disease and development”, 25 May– 28 May 2023 in Alexandroupoli, Greece.
Gemma will present her work on CasTuner and non-linear dose-responses in X-inactivation.
 

Edda presents our work on how signals are decoded at the Xist locus:

• May 16th, 10:05 am EMBL conference "Chromatin and epigenetics", #EMBLChromatin.

Gemma presents CasTuner, the CRISPR/Cas-based toolkit for analog tuning of gene expression:

• May 10th, 5.30 pm RNA club Berlin.
• May 16th, 6 pm, Bionnale Berlin "Speed Lecture Awards", register and come to vote.

We went on a two-day retreat with the group of Luca Giorgetti!
It started with icebreakers and brief project presentations. For most of the time we brainstormed on our shared research interests to develop several exciting ideas for collaboration. In between we found time for a fun hike and escape room challenge. Thanks to the Giorgetti lab and the EMBO YIP for support!

Till went to the week-long PhD course of the EMBO Young Investigator Network in Heidelberg. Daniela & Jade participated in a course at the Institut Curie in Paris. Gemma was at the meeting of her PhD training network Pep-NET in Naples. The programs included presenting the own work and workshops on soft skills, grant writing, paper reviewing, research presentations, and more. Elodie joined a course on deep reading of publications.

Our own Daniela Cecalev won a prize for best presentation & participation at the Curie institutes “18th Course on Epigenetics 2023”. Congratulations Daniela !
 

5^th X-inactivation meeting (EMBO)
19-22 June 2023, in Berlin

Registration deadline: 01 April 2023.
25 talks selected from abstracts.

Some time back, a german film team visited us for a documentary on gender medicine. It's now online, we are in the first part :

Ilona celebrates her 40-year anniversary of working at this institute! We are very grateful to have her on our team, managing the lab and doing the most challenging experiments!

Rafael Galupa will stay with us for two months to do several CRISPR screens. Welcome!
 

Jonathan Froehlich joins the team as a Postdoc. Welcome!
 

Our Nelly Kanata won a poster prize at the 2022 Max Planck Freiburg Epigenetics Meeting. Congratulations @nellykanata !
 

The new round of PhD program recruitment is open, deadline is January 6^th, 2023.

• IMPRS PhD program

Our lab proposes two potential projects. One to study how different levels in gene regulatory factors affect cellular decision. The second to study how gene regulatory DNA affects cell-to-cell heterogeneity in transcriptional responses. Both projects will be relevant to better understand gene regulation and cell fate; using CRISPR tools, genomic profiling techniques, and relevant computational analysis.

We present CasTuner, a CRISPR-based toolkit that allows analog tuning of endogenous gene expression.

We scanned the regulatory landscape of Xist and found several proximal and distal enhancers, as well as a new ncRNA Xert, that all control X-inactivation.
