On the 8th and 9th of June, the Maurice lab went on a lab retreat in the beautiful surroundings of Gun located in Limburg. We stayed at an old farm where we spend two days talking about science, getting to know each other better and doing fun activities. We made a nice overview of all the projects within the lab and brainstormed about new future projects. We also learned a lot during the workshops that were given by our colleagues about sustainability, computational analysis and entrepreneurship. Finally we had a lot of fun during the pubquiz, karaoke and treasure hunt.
After more than 40 years (!) employed by the UMC Utrecht, our lab manager Peter van Kerkhof retired. We are very happy that he joined us in the Maurice team for the last years of his career. Working at UMC Utrecht for such a long time is of course something very special. Therefore we decided to name the bridge to the lab after him! Now we always remember him when we walk over the Peter van Kerkhof bridge to the lab. He is greatly missed by all of us, take care Peter!

Laigo Bio is a targeted protein degradation biotech with programs in oncology and neurological disorders
Utrecht, Paris- February 2022 – ArgoBio and Oncode Institute have teamed up with Oncode Investigator Madelon Maurice, researcher and group leader at UMC Utrecht, to launch Laigo Bio, a new company in the emerging field of target protein degradation. The company has additionally secured funding from Oncode Bridge Fund and ArgoBio to further develop its proprietary pipeline of targeted immunotherapies SureTACsR. The SureTACsR technology platform is a novel approach in membrane protein degradation, applicable to a broad scope of disease applications. The primary focus lies in the area of oncology, but with parallel programs in neuro-inflammation and neuro degenerative diseases. In contrast to other small molecule approaches, this results in an efficient and sustained degradation of target receptors, potentially resulting in superior efficacy in the clinic than modalities currently being employed by other emerging protein degradation technologies.
Initially driven by Madelon Maurice, who will join as the Principal Investigator, Laigo Bio is gearing up for preclinical lead development in the coming months, generating proprietary biologics for a selection of targets to showcase its potential. Laigo Bio receives strong support from seasoned entrepreneurs Neill Moray Mackenzie at ArgoBio and Emil Pot at Oncode, who will prepare the company for a Series A investment round as it aims to initiate its first clinical studies in 2025. Dr. Neill Moray Mackenzie at ArgoBio is a veteran of the IO field and Mr Emil Pot is an IP & business development expert at Oncode with 25 years of experience in life sciences.
Chris De Jonghe, Valorization Director of Oncode Institute, said:
“SureTACsRis building on the innovative ideas that Dr. Maurice has initially validated with the support of Oncode’s Technology Development Fund. With the foundation of Laigo Bio, another exciting step forward is made towards the translation of Dr. Maurice’s innovations into effective, and tailored therapies for cancer patients. We are thrilled to join forces with ArgoBio in this initial seed round and consider it as a token of great confidence in the potential of this platform technology.”
Madelon Maurice of the UMC Utrecht, said:
“We are extremely happy that ArgoBio is supporting my long-standing research here at the UMC Utrecht on how to interfere with signalling alterations that drive oncogenesis and bringing a team of experienced scientists and entrepreneurs to help with its translation to the clinic.”
Dr. Neill Moray Mackenzie of ArgoBio, said:
“This is exactly why we put ArgoBio together last year – to fund these early-stage opportunities. I am especially pleased that Madelon Maurice, a renowned KOL in the field, is leading this novel approach to protein degradation which has great potential to open up a completely new biology in the field of cancer therapy.”
Shobhit Dhawan of Oncode Bridge Fund, said:
“Targeted protein degradation is an exciting space and has gained validation in clinical studies with many players now entering the field. One key differentiator here is sustained degradation of cell membrane bound proteins with a biologic, which is a very novel approach, and we believe holds a lot of promise in oncology and many neurological indications. We look forward to supporting Madelon, Neill and Emil in their journey at Laigo Bio.”

About Laigo Bio:
Laigo Bio is based on the research from the laboratory of Professor Madelon Maurice, known internationally for her contributions to the understanding of Wnt signaling, a key pathway for stem cell maintenance and tissue renewal. A main focus of her work is to uncover the mode-of-action of membrane-bound E3 ligases that control Wnt receptor turnover and are frequently mutated in cancer.
The Maurice group, based at the Center for Molecular Medicine at the University Medical Center Utrecht, and member of the national Oncode Institute, The Netherlands, has open positions for 2 postdoctoral researchers. We are looking for highly motivated and talented candidates that can join our team in the summer of 2021. The recruited postdocs will work closely with other members of our team to address molecular aspects of renewal and regeneration in intestinal and pancreas (cancer) tissues, using state-of-the-art technologies including genome editing, genomics, proteomics, (single cell) transcriptomics and imaging with organoid-based disease models.
The overall aim of our research group is to gain a fundamental understanding of the dual nature of signals that guide homeostatic tissue renewal and cancer cell growth. In healthy tissue renewal, a handful of signaling pathways supports the maintenance of small populations of adult stem cells. Deregulation of these pathways due to mutations is strongly linked to cancer development. Our main focus is to investigate how patient-derived mutations alter protein activity to promote the initiation and progression of cancer growth. With these insights we aim to uncover patient-specific disease mechanisms and develop improved cancer-targeting strategies. For more information, please visit: https://madelonmauricelab.nl/
Postdoctoral position 1: Wnt niches in cancer
A 1.5-year postdoc position, funded by Oncode, is available in our laboratory to investigate the role of Wnt niches in colorectal and pancreatic cancer subsets that display Wnt-dependent growth. In this project, we aim to identify and characterize populations of Wnt-producing niche-like cells and investigate the transcriptional programs and cell lineages that are induced by autocrine Wnt signaling within these cancer subsets. The approaches and methodologies involve organoid culture, genome editing, biochemistry, reporter assays, advanced (live) imaging, (single cell) RNAseq analysis, and mass spectrometry.

In February 2021 Susanna Plugge joined our lab as a PhD student. Susanna will work on the role of LKB1 mutations in colorectal cancer development of patients with Peutz Jegher Syndrome.
Our lab published a new review in Cell Death and Differentiation with the title “Organoid-based modeling of intestinal development, regeneration, and repair”. We discuss how Wnt and YAP signaling are involved in intestinal regeneration and compare the regenerative process with intestinal development. We focus on how organoid-based research contributed to a better understanding of these regenerative and developmental processes.
The publication can be found here.
Our lab published a new review in Nature Reviews Cancer with the title “Mutations and mechanims of WNT pathway tumour suppressors in cancer”. We discuss recent advances in the understanding of how different mutational subsets in WNT pathway tumour suppressors in human cancer link to distinct cancer types, clinical outcomes as well as treatment strategies

In October 2020 we said goodbye to Alessandra Merenda, who finished her post-doc in our lab. Alessandra started her new adventure as a scientist at HUB organoids. She received three gifts from the lab: a giant chocolate organoid cake, a jar of fortune candies (instead of fortune cookies), and a big photo book with personal messages from the group members. We will miss you, Alessa! And we hope to organize a proper goodbye dinner or borrel when this is allowed again.
In september 2020, the KWF (Royal Dutch Cancer Foundation) allocated 660.000 euros in funding for our lab to investigate how hereditary mutations in the LKB1 gene promote alterations in epithelial organization to generate a state of cancer predisposition in patients suffering from Peutz-Jeghers syndrome. We will perform this research in collaboration with our neighbors of the group of professor Edwin Cuppen.
Our publication describing how RNF43 mutations mediate a tumor suppressor-to-oncogene switch in cancer is now online at the EMBO Journal. The full article can be found here.
A video summary of our findings can be found here.
Tumor suppressor genes play an essential role in preventing uncontrolled cell division and thereby prevent cancer initiation; similar to the brake in a car. According to the dogma, cancer mutations in such a tumor suppressor genes cause loss-of-function of the gene resulting in a dysfunctional brake leading to uncontrolled growth and cancer formation. However, mutations in genes often do not result in a complete loss of the encoded protein, but rather create a shorter truncated version of the protein. The role of which is often unclear.
We previously discovered that the tumor-suppressor RNF43 controls the growth of intestinal stem cells by performing a negative feedback role in the Wnt-signaling pathway. Mutations in RNF43 are found in a variety of cancer types, including colorectal, gastric, endometrial, and pancreatic cancer. Mutations that result in loss of RNF43 function, make cancer cells hypersensitive for inhibitors of the growth signal Wnt.
However, we discovered a completely new class of RNF43 mutations that result in a shorter truncated protein. Instead of loss-of-brake function, these mutations endow RNF43 with a novel oncogenic role. Oncogenic RNF43 mutations can activate the Wnt signaling pathway in a ligand-independent manner, similar to pressing the accelerator pedal in a car. We introduced these oncogenic RNF43 mutations in human colon organoids and found that these colon organoids became insensitive to Wnt inhibitors.
Our study, therefore, stresses the importance of understanding the oncogenic mechanisms of mutations that are found in cancer patients. This is important for improved patient stratification for applications of precision medicine
