Jane/Curtis Group - Red Cell Research
Division of Blood Cancers
To identify regulators of red cell production and function including globin switching
Research Focus and Tools
- Globin switching
- ENU mutagenesis in the mouse
Globin switching - Defining the molecular mechanisms underpinning fetal (gamma) globin gene silencing may provide strategies for reactivation of gamma-gene expression, a major therapeutic objective in patients with beta-thalassemia and sickle cell disease. Our laboratory has identified and defined the NF-E2 transcription factor complex as a critical regulator of the beta globin locus. The laboratory is now focusing on the therapeutic potential of targeting PRMT5, a critical component of the complex that represses gamma globin.
ENU-mutagenesis - Chemical mutagenesis has been used to identify genetic pathways in lower organism for more than 20 years. We have recently used ENU mutagenesis in the mouse to generate mouse lines with defects in red blood cells. The laboratory has over 20 different mutant lines, revealing surprising insights into how red cells are produced and function
Projects and Opportunities
- Protein arginine methyltransferase 5 – a new target for sickle cell disease and lymphoid malignancies
- Using forward genetics to understand the regulation of red blood cells
