The Cantù Lab - Gene Regulation during Development and Disease

Claudio Cantu's research at WCMM

We study gene regulation during embryonic development, and how this leads to the formation of distinct cell types and organs.

Our body is made of more than ten trillion cells (a number that looks like this 10.000.000.000.000). When we were conceived, however, we were a single cell!
Embryonic development is that process that drives the formation of this vast number of different cells, each one executing a diverse task: transmitting the electrical impulses (neurons in the brain), contracting (muscle and pumping heart cells), transporting oxygen (red blood cells), and many others.

The problem is that all the cells within an organism (with very rare exceptions) possess the same genetic material. How could a single “instruction manual” impose a different identity to each cell?

The Cantù Lab at LiU is focused on this important goal: to discover the mechanisms of genome regulation that drive specialization during embryonic development.

Our efforts are not only aimed at solving the incredible mechanisms that generate this complexity but might also impact our understanding of human disease. Several human pathological conditions, in fact, arise precisely when the mechanisms of cell-cell communication and genome-regulation are perturbed. For example, those mechanisms that drive extensive cell proliferation in a growing embryo might be aberrantly reactivated in an adult organism and can cause cancer.

Hence, the discovery of novel molecular details of embryonic development bears the potential of generating new marker for disease disagnosis and, perhaps in the future, novel therapeutic avenues for curing such diseases.

In the Cantù lab we make use of sophisticated tools, from mouse genetics to high-throughput state-of-the-art biochemical approaches, to discover the composition of signals and the protein “arsenal” that, in each cell type, allows the activation of the correct genes, while leaving silent many others.

Our experimental efforts are focused on the so-called ‘Wnt signalling pathway’, a molecular cascade important for virtually all aspects of development, and whose deregulation causes human malformations and several forms of aggressive cancers, among which colorectal cancer.

Claudio Cantù - Bio sketch

I obtained PhD training at the University of Milano-Bicocca in the lab of Prof. Antonella Ronchi and Prof. Sergio Ottolenghi, focusing on the factors that drive the regulation of human globin genes transcription in erythroid cells, and how fetal genes are replaced by adult ones, a process known as “globin switching”. A summer stay in Oxford (UK) in the lab or Prof. Tariq Enver at the Weatherall Institute of Molecular Medicine, working 24/7 with Dr. Cristina Fugazza, allowed me to identify and focus on one specific protein, the transcription factor SOX6. In 2011 I changed field and joined the developmental genetics lab of Prof. Dr. Konrad Basler, at the University of Zurich, Switzerland, and started an ambitious research program in which I applied the genetic knowledge obtained in Drosophila melanogaster to study mammalian genetics.

I generated a series or mutant mouse strains that allowed me to dissect several aspects of how the Wnt pathway is transduced in different cell types during development. Here, many persons shaped my scientific growth in addition to Koni Basler, from George Hausmann, to Tomas Valenta, Dario Zimmerli, Nick Doumpas, Christian Mosimann and Erich Brunner – to mention a few.

My efforts generated a series of scientific discoveries that not only revealed how little was known about signaling pathways, but also shown how these mechanisms are employed or hijacked by cancer cells. In February 2018, I moved from Switzerland to Sweden, when I was awarded a generous research starting grant from the Knut och Alice Wallenberg Foundation. This allowed me to build a research group focused on the mechanisms via which cells influence each other´s genomes during development.

Pierfrancesco Pagella - Bio sketch

Pierfrancesco was born in Alessandria, Italy. He studied Biology at the University of Milano-Bicocca from 2005 to 2011, and then moved to Zurich, Switzerland. During his PhD and his postdoc at the University of Zurich, he focused on the study of teeth, an incredibly powerful model for the study of developmental and evolutionary biology. In this system, he identified and characterized non-canonical functions of several molecules – including the neurotrophin Nerve Growth Factor, the neurite growth inhibitor Nogo-A, and the Wnt/β-catenin transcriptional coactivators Bcl9/9L and Pygo1/2. As Oberassistant/Junior Group Leader at the University of Zurich, he set up microfluidic culture systems to emulate complex organs in vitro, with the aim of modeling and imaging developmental processes. With these microfluidic devices, he could faithfully recapitulate the in vivo tooth innervation patterns.

He exploited these culture systems to compare the neurotrophic properties of dental pulp and bone marrow stromal cells, cell populations currently studied in the context of hard tissue regeneration, as well as cancer cells. In a parallel line of research, he applied single cell RNA sequencing to determine the cellular composition of human teeth, realizing a comprehensive single cell atlas of human teeth.
In April 2021, he joined the lab of Prof. Claudio Cantù at Linkoping University, to gain expertise in the study of chromatin structure, protein / DNA interactions, and how these events affect major developmental and pathological processes.

Simon Söderholm - Bio sketch

Simon is from a smaller town called Söderköping located in Östergötland County, Sweden. He started his academic journey studying environmental science at Linköping University, Campus Norrköping. After receiving a bachelor’s degree, Simon then worked in the industry as an environment- and quality technician. After a number of years, he moved to Linköping and decided to start studying again, this time Chemical Biology, which was more in line with his interest in the molecular aspects of biology. During his Master’s he also went into the world of computational biology and bioinformatics, which was – he feels – a natural step giving his strong interest and experience in programming. After that, he worked as a research assistant until he started his doctoral training in the Claudio Cantù lab. 
The overall aim of his work, common to the aim of the group as a whole, revolves around studying tissue-specific properties of Wnt signaling, using genome-wide sequencing technologies and computational methods.

The long-term goal is to better understand how this seemingly linear process is able to act in such a versatile manner, knowledge that could improve our ability to treat diseases such as cancer.

Outside of work, Simon´s hobbies include writing novels, programming games and taking care of collections of coins and fossils/minerals.

Simon Söderholm points to the identification of a small region, within the vast genome, that contains the small group of genes identified in the new study, which is important for the ability of embryonic stem cells to decide whether to divide or become specialized cells. Simon combined experimentation with sophisticated informatic analyses to identify the behaviour of these genes. Photo credit John Karlsson

Salome Brütsch - Bio sketch

Salome was born in a small town close to Zurich. She studied biology at the University of Zurich and performed her Master thesis in the Konrad Basler lab under the supervision of Claudio Cantù working on TBX3 and BCL9, both proteins involved in Wnt signaling. After the Master’s degree Salome decided to dive into a new topic and started her PhD in the lab of Sabine Werner in a small subgroup led by Mattia Bordoli. She studied VLK/Pkdcc, the first and so far only known secreted tyrosine kinase, in the mouse model and observed perinatal lethality upon mesenchyme-specific deletion of VLK/Pkdcc. The project initially outlined for wound healing went to a completely different direction. Salome wanted to find out why the mesenchyme-specific VLK/Pkdcc knockout is lethal and therefore she became the first person in the Werner lab that studied a protein in the context of embryonic lung development.

After completion of her doctoral studies Salome joined the Cantù lab in February 2023 for a short postdoctoral fellowship to work again on the interesting transcription factor TBX3.

Outside of work Salome enjoys to do sports, on weekends she loves to spend time in nature, hiking, road cycling and trying to cross country ski. She also enjoys having good conversations with friends accompanied by a good wine. During the week you can find her in various group fitness classes and at home relaxing through reading, listening to podcasts and doing Makrameh for all the baby plants she tries to raise.

Tamina Weiss - Bio sketch

Tamina Weiss grew up in the south of Germany and holds a bachelor’s degree in molecular medicine from the Medical University in Innsbruck. Shortly after she started the double degree program. During her studies in Biomedicine at Linköping University she joined Markus Heilig group to investigate the neural circuitry of a neuronal subpopulation of the rat central amygdala that are functionally linked to compulsive behaviour in alcohol dependent rats. Driven by her interest in how to model complex systems in vitro she studied tissue engineering and regenerative medicine at the University of Applied Sciences in Vienna. Via a short stay at Karolinska Insitutet, to learn about iPS reprogramming and 2D neuronal differentiation systems, she joined the Anna Falk group at Lund University for her thesis project. She developed 3D forebrain organoids from an individual diagnosed with autism to study the role of a presynaptic adhesion molecule in early neurodevelopment.

Her interest in the capacity of cells to self-organize into highly organized structures and how this is regulated by precisely timed pathways, specifically the role of WNT in different tissues and during different stages in development, and gene dynamics is what motivated her to join Claudio Cantù Lab in the scope of a preparatory research course.

Ongoing Projects

1. Tissue-Specific Wnt-Signalling

A protein called β-catenin orchestrates canonical Wnt target gene expression by recruiting a host of co-factors to Wnt-responsive elements on the DNA, occupied by TCF/LEF transcription factors. Our recent data indicate that the Wnt/β-catenin pathway can affect gene expression in a tissue-specific manner by the recruitment of tissue-specific co-factors. Several of our lines of investigations aim at discovering how cell-type-specific players contribute to the execution of the Wnt-mediated transcription in different cell types: a fundamental question in the field of Developmental Biology.

2. Finding a Therapeutic Window to Treat Colon Cancer

Colorectal cancer (CRC) is prominently caused by uncontrolled activation of the Wnt signalling pathway. However, a complete inhibition of this pathway would have devastating effects on normal tissue homeostasis. In vivo abrogation, in the mouse, of the interaction between β-catenin and BCL9 leads to the loss of metastatic traits without perturbing normal homeostasis. As BCL9 proteins serve as scaffold to a dynamic protein complex that represses and activates Wnt target genes, we are investigating the CRC-specific composition of the Wnt-dependent β-catenin/BCL9 transcriptional complex, as a fundamental first step to identify new players and protein-protein interaction surfaces that might constitute future therapeutic targets. This quest is tightly connected to our fundamental question of embryology: one of our current hypotheses is that one of the regulators of CRC metastasis is TBX3, previously identified by us as a Wnt player in limb development.

3. The Interface Between Transcriptional Regulation and Chromatin Landscape

A central theme of this research line is to understand the relation between the Wnt pathway-mediated transcription and the tissue-specific regulation of chromatin function. We are working hard to respond to the following question: does Wnt signaling impose a specific chromatin structure and function? Or, on the other hand, does the tissue-specific context (i.e. chromatin structure of individual cells) act as fundamental constrain defining how individual cells will respond to Wnt stimulation? This is an ambitious line of investigation that will bring together two fields of research: the study of developmental pathways and molecular epigenetics.

4.The role of Wnt/BCL9 in Congenital Heart Disease (CHD)

We have previously found that the Wnt regulator BCL9 is an important player of heart development. We now hypothesize that genetic variations in the genomic BCL9-regulated regulatory regions might contribute to the onset of congenital heart disorders.
