Our LHOP Biobank received the SBP VITA Label
Building up a proper Governance through accountable mechanisms is key to foster trustworthiness and the prerequisite for the appropriate use of biological resources. Our LHOP Biobank has recently been awarded by Swiss Biobanking Platform (SBP) with the VITA Label, which demonstrates compliance with the applicable legal and ethical framework. This labelling approach is part of our long-term strategy to strengthen biobanking practices and provide high-quality samples to the research community.

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. Please click here for more information and manuscript download.

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.

A 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.

A 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.
