Eva Hellström-Lindberg group
Eva Hellström-Lindberg chairs a translational research program targeting the myelodysplastic syndromes (MDS).
The experimental part focuses on pathogenesis and therapeutic targets in MDS and is pursued along three lines:
- Hemopoietic stem cell (HSC) studies in specific MDS subtypes aiming to understand clonal hierarchies, mechanisms for HSC-niche interactions, and response to therapy;
- Studies of the MDS subtype refractory anemia with ring sideroblasts, RARS, exploring the biological consequences of mutations in the splice factor gene SF3B1 for HSC clonal advantage and anemia, respectively;
- Epigenetic dysregulation in high-risk MDS including how genetic and epigenetic patterns are influenced by treatment.
These studies are made possible by a large MDS biobank encompassing DNA, RNA and cryopreserved cells from the MDS clinic at Karolinska and from the Nordic Clinical trials. Patients undergo a detailed annotation and follow-up and are genotyped with regard to currently identified candidate gene mutations.
The clinical trial program (Nordic MDS group) encompasses phase I and II clinical trials, and is associated with an elaborate biobank program. In Sweden, this program is linked to the Swedish Cancer Registry quality system, and similar registries are currently developed in the other Nordic countries.
The MDS group is actively engaged in a number of productive international collaborations, as demonstrated in the publication short list.
- Swedish Cancer Society
- Swedish Research Council
- Stockholm County Council Research funds
- Cancer Society in Stockholm
- Nordic Cancer Union
