We are delighted to announce that our ESRs Eva Sophie Schönegger (baseclick/LMU) and Ahmad Abdullrahman (University of Reading) recently passed their viva. Eva spent her NATURE-ETN journey at the company baseclick and the Carell group at LMU Munich, while Ahmad completed his PhD at the University of Reading under the co-supervision of Dr. James Hall and Prof. Christine Cardin.
We congratulate Dr. Schönegger and Dr. Abdullrahman on this key milestone in their career!
Our former ESR, now postdoc at the University of Reading, Tayler D. Prieto published a new paper in Chemical Science, titled “Re-pairing DNA: binding of a ruthenium phi complex to a double mismatch”, in collaboration with Diamond Light Source Ltd. and the Kellett group at the Dublin City University.
The paper is available Open Access on the publisher’s website.
We are glad to announce that our ESR, Tayler David Prieto, successfully completed his PhD under the supervision of Prof. Christine Cardin at the University of Reading, UK.
You can find his publications on the Dissemination page.
We congratulate Dr Prieto for this key milestone in his career and wish him all the best for the future steps!
On the 9th and 10th of November 2023, the Gasser group at Chimie ParisTech hosted the NATURE-ETN Symposium at their premises in Paris, France.
The Symposium was centred on the path from basic research to commercialisation and/or clinical trials. We had the privilege to hear from eminent speakers such as Marie Dutreix (Institut Curie, co-founder of DNA Therapeutics), Thomas Carell (Founder of baseclick), Tom Brown (co-founder of three biotechs, including our partner ATDBio), Nick Farrell (Virginia Commonwealth University), Patrick Couvreur (University Paris-Saclay and serial entrepreneur), Laurence Mulard (Institut Pasteur), and Mark Bazett (Director of Preclinical Development at Bold Therapeutics Inc.).
Some ESRs also presented their poster during the event reception at the beautiful Chimie ParisTech library.
We thank the Gasser group for the smooth organisation, as well as all the speakers for their precious insights from basic science to applications.
We have the pleasure to announce that Maria Dalla Pozza, ESR in the Gasser Group at PSL University, passed her viva and successfully completed her PhD!
You can find her publications on the Dissemination page.
We congratulate Dr Dalla Pozza for this key milestone in her career and wish her all the best in her future endeavours!
Collaborative work between researchers from the University of the Free World in South Africa and the Gasser group at PSL University has just been published in Inorganic Chemistry. This work notably includes a contribution from our ESR Maria Dalla Pozza.
This paper presents Re(I) carbonyl complexes with exceptionally low nanomolar cytotoxic activity toward prostate cancer cells, demonstrating further the future viability of utilising rhenium in the fight against cancer.
It is available Open Access here.
Our ESR Tania Sánchez Quirante from the Hocek group at the Institute of Organic Chemistry and Biochemistry in Czechia recently did two secondments at the Universities of Warsaw (Poland) and Oxford (UK).
From January to February 2023, Tania did her first secondment at the Laboratory of Chemical Biology and Biophysical Chemistry at the University of Warsaw, where she synthesized and purified modified cap RNA 70nt long and modified mRNA by in-vitro transcription. She also learned how to do in-vitro translation using the rabbit reticulocyte system.
In April 2023, she stayed at the Tom Brown group at the University of Oxford. She synthesized modified single-guide RNA 99nt long by in-vitro transcription reaction and used this sgRNA to perform CRISPR-Cas experiments. In addition, she did stability experiments of the modified sgRNA in Human serum.
The Early-Stage Researchers (ESRs) were thrilled to participate in the 5th training week about nucleic acids and crystallography. The first two days were spent attending the Oligo 2023 conference in Oxford. They listened to experts talk about nucleic acid, base modification, aptamers, and more. They were fascinated by the new developments and ideas in this field.
After the conference, the ESRs visited the Oxford Nanopore Technologies research facilities. They gained a deep understanding of how the research industry works and how scientists turn their ideas into reality. The ESRs were impressed by the state-of-the-art facilities and the advanced equipment used for research.
The next two days were spent at the University of Reading, where the ESRs attended engaging talks about crystallography and data processing. They had the opportunity to participate in hands-on activities such as crystallisation, plate preparation, high throughput robot, and learning to recognise and collect good crystals. Finally, they collected data from the X-ray, which was an exciting experience for them.
After a free afternoon spent in London, the ESRs were welcomed at Diamond Light Source. They were given an intense tour of the different facilities and beam lines available at the synchrotron. They gained an understanding of the Cryo-EM and laser technology used in the field of structural biology for protein and nucleic acids. It was an eye-opening experience for them, and they had a lot of fun learning about this exciting field. Overall, the ESRs found the 5th training week about nucleic acids and crystallography to be an enlightening experience. They were exposed to the latest developments in the field, and the hands-on experience provided them with a deeper understanding of the processes involved. They were inspired to continue their research with renewed enthusiasm and curiosity.

Professor Tom Brown (University of Oxford) will be a speaker at the webinar “Traditional and Emerging Methods of Oligonucleotide Synthesis”, organised by Biotage and taking place on the 5th of April at 11am CEST.
Prof. Brown will review the history of oligonucleotide synthesis, examine how they are made currently and highlight emerging synthesis methods, including enzymatic approaches. He will also discuss the various applications of synthetic oligonucleotides, from diagnostics to therapeutics and more.

The communication paper of ESR Eva Schönegger and Dr. Antony Crisp from baseclick GmbH in collaboration with the LMU Munich, Institute for Chemical Epigenetics Munich was published in September 2022 in Bioconjugate Chemistry.
In this communication paper, entitled Click Chemistry Enables Rapid Amplification of Full-Length Reverse Transcripts for Long-Read Third Generation Sequencing, Eva, Dr. Antony Crisp, Dr. Markus Müller and coworkers describe the development of a novel click chemistry-based method for the generation and amplification of full-length cDNA libraries from total RNA.
In this work, supervised by Prof. Thomas Carell (LMU) and Dr. Thomas Frischmuth (baseclick), the use of click chemistry circumvents the need for the problematic template-switching reaction.
The use of PCR primers containing two overhanging 3′-nucleotides is one essential modification of the described workflow resulting in a significantly improved read-through compatibility of the 1,4-disubstituted 1,2,3-triazole-containing cDNA, where these modifications normally hinder amplification. This enables to use an insert size which is twice as large compared to the state-of-the art click chemistry-based technique, PAC-seq.
Taking the known advantages of PAC-seq, such as suppression of PCR artefacts, into consideration, the described library preparation method could enable various applications, including improved analyses of mRNA splicing variants and fusion transcripts.
