Ever think of using the Tet-On/Off system in beta cells? Have a look at our recent pre-print by lead authour Dr. Nathalie Jouvet when designing your experiments.
Excited to share a new study we published comparing the pros and cons of common rodent diets when trying to model NAFLD. Congrats to my talented team, led by student Hannah Zhang!
We are searching for a Canadian post-doctoral fellow interesting in liver/beta-cell cross-talk and molecular changes that occur in the early stages of diabetes. Start date: as soon as possible. Check out the Available Positions page for more details on how to apply.
Our paper looking at the link between PGC-1alpha and inflammatory signaling in hepatocytes is out in Molecular Metabolism! A new function for a short form of the canonical protein.
Times have changed considerably and we are adapting day-by-day to the challenges posed by Covid-19. Currently, our lab is closed. We are looking forward to the time when we can restart our research on metabolic disease.
In the meantime, I want to commend the dedicated members of my lab who are remaining strong through this crisis. We will get through this together.
A huge congratulations to Dr. Mélissa Léveillé, who successfully defended her doctoral thesis on March 25th! She did an amazing job at her virtual defence, one of only many challenges Mélissa faced during her PhD training. We are all so proud!!
Congratulations to Hannah Zhang for winning best Pitch Talk at the MDRC Annual Scientific Day. Also many thanks to Diabetes Quebec for funding our lab to create a new mouse model to study beta cell function!
Congratulations to Mélissa Léveillé for receiving the Montreal Diabetes Research Centre Travel Award, and Hannah Zhang for receiving the Graduate Research Enhancement & Travel (GREAT) Award from McGill and the Keystone Symposia Future of Science Fund scholarship! They will be attending the Keystone meeting on Obesity and NAFLD: Mechanisms and Therapeutics in Banff in February 2020!

Another successful retreat for the IRCM at Estrimont this year. My lab
sweeped the competition by winning 3 prizes for best posters and oral presentations. Congrats to Emilie, Philipa and Mélissa for their wins! Can you spot us all in the picture?
May was a busy month! We were lucky to have some press coverage of our recent work in the media – seems we have a lot more to learn about the role of glucagon in the control of blood glucose. (RadioCanada)
I was honoured to be invited to speak at this year’s Pint-Of-Science in Montreal. It was a great night and a fun venue. I recommend these events to anyone who wants to find out what scientists do, ask questions about their work, and simply to have a pint with cool people.
Thank you to all the generous donors who supported our team in the IRCM Challenge! We raised $2850 this year and braved the cold, rainy weather to all finish the race. Well done Anti-Diabetic Agents!!
Congratulations to Hannah Zhang, an undergrad trainee in my lab who was just awarded the prestigious CGS – Master’s Award for her graduate work in our lab, starting in the Fall – wish her luck!
An interesting article in La Presse+ discussing our recent discovery linking PGC-1A and hepatic insulin signaling. Encouraging words that we should think about glucagon (and PGC-1alpha) differently in the context of diabetes.
The Estall Lab was excited to be a part of the A-BC Islet Workshop this year in snowy Kelowna, BC! Great 2 days of science and networking (and my bowling score improved 10-fold over last year).
Hot off the press! We just published a paper in PNAS showing that PGC-1 in liver is important for regulating blood glucose levels, in more ways than expected. Seems PGC-1alpha, downstream of glucagon, controls the IRS1:IRS2 ratio to help insulin to shut down hepatic glucose output right after a meal.
Check out the work by our team here: PGC1A regulates the IRS1:IRS2 ratio during fasting to influence hepatic metabolism downstream of insulin.
Look who won prizes for best poster at the MDRC Annual Retreat!! Congratulations to Philipa (MSc student) and Stewart (Post-Doc). As per tradition, drinks were on them that night…
Mélissa gearing up for her “Pitch Talk” at the MDRC annual Retreat on whether we should care about PGC-1alpha levels in liver cancer linked to obesity. She did a great job convincing us we should!
Happy New Year everyone! To escape the wintery weather, we had our first ever lab curling event. Although we were all rookies, we were surprisingly good!
Congratulations Philipa for being awarded the JA DeSeve Excellence Scholarship from the FESP!
A warm welcome to Yeliz Yilmaz (an exchange PhD student) and Dr. Aysim Gunes (a post-doctoral fellow) from Turkey (Dokuz Eylül University), both coming to learn the metabolic side of liver cancer linked to obesity. We are also looking forward to learning about cellular mechanisms of liver cancer from them, in collaboration with Drs. Nese Atabey and Mehmet Ozturk.
Congratulations to our own Dr. Stewart Jeromson for being awarded a prestigious Post-doc Fellowship from Diabetes Canada. Well-deserved! And many thanks to Diabetes Canada for their continued support of our research.
In an article published in Montréal InVivo, Philipa talks about her unconventional start in Molecular Biology and how that path led her to our lab as a graduate student!
Thanks to pioneering work done by the Larose Lab, we are now embarking on understanding whether Nck proteins can or should be targeted to treat diabetes. Here is the first published work on this – a collaborative effort opening a new chapter in the Estall Lab.
Congratulations to the now Dr. Aurèle Besse-Patin, who successfully defended his PhD and passed with flying colours!
Woohoo! Philipa has won a Master’s scholarship from the MDRC for her work on hepatokines secreted from fatty liver.
It was great to catch up with the Canadian (and the token brit) beta cell experts at the A-BC Islet Workshop in Kelowna, BC. I learned many new things (and confirmed that bowling is not my forté).
We’ve had a busy winter! Hope you had a chance to see Philipa give her talk at the recent Organ Crosstalk in Obesity and NAFLD Keystone meeting in Colorado. If not, stay tuned for more about liver hepatokines and diabetes in the future from the Estall Lab.
Ever wonder if mutations of PGC-1α are linked to metabolic disease and why? Read our paper reviewing the basic and clinical research on one particular mutation and diabetes. Thanks to Roxy and Naveen for the hard work putting it together!

Congratulations to Stewart Jeromson for obtaining a post-doctoral fellowship from the IRCM! Now you only have to successfully defend your PhD in a few weeks to get it – No pressure 🙂
Another travel award for Aurèle Besse-Patin for his work on sex and NASH! Thanks to the MDRC for their continued support for own lab.
We sometimes get out to rest too, trust me 🙂 After a good afternoon of team building in escape rooms, we got to chill by a roof-top pool before going out.
And she’s back! We somehow convinced Philipa Levesque-Damphousse to return after her internship last summer to complete her Master’s degree. Welcome back to our team and looking forward to seeing her projects develop on novel hepatokines in diabetes.
My students are on fire this year! Both Roxy and Aurèle won prizes for best poster and oral presentations at IRCM research day.
Drinks were definitely on them that night 🙂
Congratulations to my amazing lab team, The Anti-Diabetic Agents, for raising $2163 for the IRCM challenge run this year! It was a great day and the rain held off just long enough for us to enjoy it 🙂 Very proud of all my current (and future) team members who participated, completing the race pushing carriages, wearing costumes, and on sprained ankles!
Roxy took the stage at the Boston/Ithica Islet Club meeting in New Haven, Connecticut to represent our lab and present her Master’s project. She did an awesome job!
