Poster prize for Saskia de Man at the 2019 GRC on Wnt signalling

Saskia and Renée attended the 2019 GRC on Wnt signaling in Vermont.

Preceding the GRC, Saskia attended the GRS, where she chaired one of the sessions. Renée also chaired a session at the GRC, organised the power hour and gave a talk highlighting the lab’s ongoing work on Wnt gene regulation and functional imaging of Wnt signal transduction. Saskia presented her work in one of the GRC poster sessions and, as icing on the cake, won one of the poster prizes.

It was a great and interactive meeting and we return to the lab invigorated with lots of great feedback and new ideas.
The next Wnt meeting will take place in September 2020 in Japan. The Wnt meeting will return as a GRC meeting in 2021 and 2023 (location to be announced) and rumor has it that the 2022 Wnt meeting may be held in China or Singapore.

11th ENBDC workshop on mammary gland biology and breast cancer

Renée travelled to Switzerland for the 11th annual meeting of ENBDC members. This also served as an annual reminder for the lab group picture (see icon on the left and the full size image as part of the time capsule on our alumni page).

Zuzana Koledova organized and chaired a fantastic Weggis meeting. Renée presented a poster and also enjoyed the group hike up a very sunny mount Rigi.

5 year Wntlab anniversary

We celebrated the 5 year anniversary of the Wntlab by hosting our first reunion for alumni. It was really good to see so many of our former BSc and MSc students return to Science Park and to hear about their diverse and exciting career steps.

The blues

Anoeska brought cake to celebrate the first glimpse of a signal in our new mTurquoise reporter. This is the first mouse strain in the lab generated by CRISPR/Cas9 editing (a collaboration with Ivo Huijbers and Lona Kroese at the Netherlands Cancer Institute).

Awesome Wnt cake

The students celebrated the start of their internships by treating us to an exciting cake:

Grand tour of Germany

Renee visited Jena (8 hours by train from Amsterdam) for a PhD committee meeting and gave a talk at the Leibniz center for Aging. Then she took a train to Munich, where she spent the weekend working in a hotel room. On Sunday she met up with Larissa to visit collaborator Christina Scheel for some inside tips on human breast organoid cultures. Six days well spent!

Welcome students

Beau, Delano and Kyah started their BSc internships. With their arrival, the lab is crowded and all supervisors are busy again. Here is to happy cloning and good results!

Feature in KWF magazine

Renée was featured in "Sterker", the magazine for KWF donors. She was invited to talk about the link between science and art.

Volkskrant article on cardiac stem cells

Renée contributed to an article in the Volkskrant by journalist Nienke Zoetbrood.

The piece focuses on a recent study by Hans Clevers and colleagues and discusses the scientific quest to demonstrate the existence (or absence) of cardiac stem cells.

Evo-Devo talk for high school teachers

On Saturday morning Renée gave a talk at the 2019 NIBI conference for high school teachers, which was held in Lunteren. This year’s theme was "Evolutie in Actie" ("evolution in action") and the program offered a dazzling number of (interactive) lectures and workshops covering all aspects of evolution.

Renée covered multiple aspects of development, covering both shared features of the body plan in multicellular animals (axis formation, segmentation) as well as fascinating species specific traits - such as why elephants don’t get cancer or the polydactyly observed in Hemingway cats.
In doing so, the audience of about 75 people dove deep into the secrets of the DNA.
Hopefully everyone will return to their classroom inspired - determined to no longer use the term "junk DNA" and ready to dazzle the next generation of biologists with new insights into the molecular mechanisms of chromatin packaging, long-range regulatory enhancers and CRISPR gene-editing technology.

First preprint for the lab

We published our first pre-print on Biorxiv:


First author is Tanne van der Wal, who did her BSc internship in the lab. Co-authors are Jan-Paul Lambooij (a technician from the Netherlands Cancer Institute who performed a lot of the experiments together with Renée way back when) and Katrin Wiese (who was instrumental in helping with the FACS analysis to determine the orientation of the TMEM98 protein in the cell membrane).

As detailed in this thread on Twitter, this story has been a long time in the making.

The gist of the story in layman’s terms/for the general public:
We know that the human genome contains the information to make approximately 20,000 different proteins. But we know very little about the molecular function of many of these proteins. Finding out what a specific protein is doing inside the cell can be a lot of hard work: You have to figure out where it hangs out, who it is interacting with and which molecular processes it is affecting.
In this study, we investigated the role and behavior of a protein called TMEM98. We found out that it travels to many different locations inside the cell, including the plasma membrane. We also studied the interaction between TMEM98 and another protein, called FRAT2 - which can activate the WNT signaling pathway (and this is one of the important molecular routes that cells use to communicate with each other: because of that, WNT signaling is a main focus of research in our lab).

Why is this important? Well, the TMEM98 gene has been found to be mutated in patients with an eye disorder called nanophthalmos. These patients are at higher risk of developing glaucoma. Understanding the role of this protein can, in the future, hopefully help explain the origin of this disorder. Finally, recent studies also suggest that the TMEM98 protein may play a role in cancer, atherosclerosis and immune cell differentiation. Our study provides a small piece of the puzzle for ultimately understanding of how TMEM98 works to control so many different aspects of cell behavior.

Welcome Rianne

Rianne started her first MSc internship in December. She joined the other Molecular Cytology internship students for a cloning class under the supervision of Anna, and imaged her first fluorescent fusion protein constructs before Christmas!
She will be working under the joint supervision of Saskia and Marten Postma on the functional imaging of Wnt signal transduction.

Next step for Anoeska

Today was officially the last day that Anoeska was employed as a PhD student. We were already slowly getting used to this, as she had been working in the lab part time since taking on a new job as management assistant in our institute.

We celebrated with some goodbye cake and a picture in her new office, which is only a few doors down from the rest of the lab. The chapters for the thesis have been outlined and there are plenty of exciting data to be discussed - so here’s to a smooth writing process. Good luck Anoeska!

ENBDC Think Tank in Bilbao

Renée visited Bilbao for the second time in two weeks (what are the chances...) for a Think Tank meeting of the ENBDC organizing committee. Maria del Mar Vivanco took excellent care of the organization, which not only included the scientific program but also some really good pintxos.
It was good to discuss science for a full day without any other distractions - especially in such great company.

Thesis defense in Bilbao

Renee chaired the PhD thesis defense committee of Virginia Murillo, who did her PhD research with Dr. Robert Kypta at CIC bioGUNE in Bilbao. The defense took place at the University of the Basque country and ensured interesting scientific discussions about WNT11 and FZD8 and their role in prostate cancer.

Family and friends ensured that delicious local wine and home cooked dishes were available to celebrate after the defense, so it was both a scientific and culinary highlight. On top of that, it is nice to see the similarities and differences between PhD defenses in so many different countries and now Spain can be added to the list.

The lab turns 5

It is a little hard to believe that we can already celebrate our five year anniversary: Apparently time indeed flies when you are having fun (or when you do not stop to smell the roses).
Renée is very proud of the entire Wntlab, because together we have been able to set up an entire line of research at the University of Amsterdam from scratch. The first PhD thesis is going to be written and we are about to start profiting from some of our longer-term efforts and investments.

A thread with "5 things I learned as a PI" apparently struck a chord and gained some traction on Twitter. See if you agree by reading it here.

We celebrated small with some impromptu drinks (and a bit of cake and fireworks - very befitting of a 5-year old) and hope to get together for a reunion with all of our student alumni soon.

Wrapping up the Grassroots project

The computer game that was developed as part of the Grassroots project (awarded to Renee and Gooitzen Zwanenburg in the fall of 2017) was put to the test by the third year BSc students in the Frontiers in Medical Biology course.

Thanks to Abel Stam, the board game was shapeshifted into version 1.0 of a visual model of stem cell division in the intestinal crypt. It can already be used to illustrate principal concepts of stem cell biology. In the future, we hope to develop it into a version that can be used to essentially perform lineage tracing analyses in silico - thus mimicking an expensive and time consuming experiment that is normally performed in vivo.
