Wonderful news! The LHOP has been awarded a 4-year SNSF Research grant for a project entitled “Deciphering the functional role of ALK and TWIST1 in neuroblastoma development and progression”. Congratulation to Annick Mühlethaler who will be the PI for this work! This phenomenal support will further strengthen and foster the LHOP’s expertise and decade-long experience in the field of neuroblastoma.

 

13th September 2019

The LHOP has been awarded a very generous research equipment grant from the Loterie Romande for the acquisition of a erythocyte ekatcytometer with the capacity to study red cells in health and disease under variable osmotic and oxygen-tension conditions! This will be one of the very few machines available in Europe at this time. We are immensely grateful for this support!

Congratulations to Fréderica Schyrr for her paper just having been accepted for publication in American Journal of Hematology! This manuscript delineates the optimal preoperative care of children with sickle cell disease. Fréderica and the team performed a very extensive systematic review and issued key recommendations that will most certainly impact care.

Congratulations to our Lab Head Dr Raffaele Renella who has been awarded a research grant from the Novartis’ Foundation of Medical-Biological research for this project on erythroid multiomics.

Congratulations to MD-PhD Student Frédérica Schyrr (member of the Naveiras Laboratory at the EPFL) whose abstract on a PRISMA-based systematic review on the perioperative care of children and adults with sickle cell disease has been selected for poster presentation at the 24th European Hematology Association Congress in Amsterdam (Netherlands). This very important collaborative effort under the supervision of our Lab Head Dr Raffaele Renella has helped to highlight recommendations, devise a risk-assessment algorithm and identify research priorities in this area.

Congratulations to Lucie Vivancos Stalin for her paper just having been accepted for publication in Frontiers in Oncology! This great contribution is reporting on the expression of the neuroblastoma-associated ALK-F1174L activating mutation during embryogenesis, and the associated impairment in the differentiation of neural crest progenitors in sympathetic ganglia. Lucie and colleagues report for the first time that the expression of the human ALK-F1174L mutation in NCCs during embryonic development profoundly disturbs early sympathetic progenitor differentiation, in addition to increasing their proliferation, both mechanisms being potential crucial events in NB oncogenesis.

Congratulations to Julien Delobel, post-doc in the lab, who won the “Best Contribution” award at the 22nd European Red Blood Cell Society (ERCS) Meeting in Ascona, Switzerland! The lab was well represented at this event with 2 oral presentations, on developing newborn screening for sickle cell disease with a paper-test (Delobel), and on surfaceomics of erythropoiesis in health and disease (Renella).

 

3rd December 2018

AN INCREDIBLE END OF THE YEAR!

The LHOP just delivered two oral presentations at the 60th Meeting of the American Society of Hematology in San Diego, California! Our post-doc Julien Delobel presented on “Harnessing the Power of Global Health Studies for Sickle Cell Disease: Validation of a Rapid, Open-Source, Paper-Based Screening Assay in a Cohort of 1103 Tanzanian Children”, which resulted from a collaboration with the Swiss Tropical and Public Health Institute in Basel. In addition, congrats to Julien Delobel who received an ASH Abstract Achievement Award for his work! This is a fantastic achievement.

Our lab head Raffaele Renella presented on “Congenital X-linked Myelodysplasia with Tetraploidy is Associated with De Novo Germline C-terminal Mutation of SEPT6, a Septin Filament Protein”, which resulted from a collaboration with Boston Children’s Hospital, Harvard Medical School. In addition, Raffaele Renella was invited to talk on “Seizing Opportunities in the Molecular and Cellular Dissection of Unique Phenotypes in Pediatric Myelodysplastic Syndromes” at the Scientific Workshop on Inherited Hematopoietic Malignancies.

 

7th September 2018

Sometimes it is good to celebrate a non-scientific group achievement! Our lab was able to complete the Escape Game (The Key Einstein) in Lausanne during our start of the academic year outing in 58 minutes! Clearly a world record, which was celebrated with dinner & drinks!

 

 

 

 

1st May 2018

Congratulations to Dr Maria-Vittoria Sepporta and Lucie Vivancos, PhD candidate in the lab, who both have been selected to present their research at the Advances in Neuroblastoma Research Conference, scheduled for May 9, 2018 – May 12, 2018, at the San Francisco Hyatt Regency Hotel.

9th of January 2017

We are delighted to welcome Dr Julien Delobel PhD to our laboratory. Julien is coming to us from Berlin and will be a SNSF Post-doctoral researcher in the lab working with Dr Raffaele Renella MD PhD on the cellular surfaceome of healthy and Sickle Cell Disease erythropoiesis.

 

10th of October 2016

A new manuscript by the lab has just been published in BMC Cancer investigating the role of Aldehyde Dehydrogenase (ALDH) in the aggressive phenotype of neuroblastoma! Interestingly, the enzymatic activity of ALDH plays a role in the aggressive properties and the 4-hydroxycyclophosphamide resistance of NB, and our team shows ALDH1A3 isoenzyme activity increases the aggressive capacities of a subset of NB cells. Congratulations to all of the co-authors for this great achievement and contribution.

jciA paper by Drs Brendel, Guda, Renella and others under the leadership of Prof David A Williams (Boston Children’s Hospital, Dana-Farber Cancer Institute, Harvard Medical School, Boston, USA) reporting of a pre-clinical gene therapy study for sickle cell disease has been published in the Journal of Clinical Investigation today! In this paper, work initiated by Drs Renella and Milsom in the Williams Laboratory in 2011 has paved the way for a novel gene therapy approach for sickle cell disease, aiming at inducing the expression of fatal haemoglobin (HbF) by knocking down BCL11A, a protein involved in the haemoglobin switch. For more details and explanations please see the Harvard Medical School Gazette article and the STAT website article covering this publication.

maxresdefaultA paper by Dr Philip Altrock (Dana-Farber Cancer Institute, Harvard Medical School, Boston, USA) and colleagues, with the contribution of Dr Raffaele Renella, has been published early online in the American Journal of Hematology this week. It explores an integrative theoretical and experimental approach, which has identified the target frequency of HSC alterations required for effective treatment of sickling syndromes in humans. This work replaces episodic observations of such target frequencies with a mathematical modeling framework that covers a large and continuous spectrum of chimerism conditions.
