GEMMs addressing Pax5 loss-of-function in childhood pB-ALL

Genetically Engineered Murine Models (GEMMs) represent a promising approach to create individualized and precise models reproducing the molecular makeup of the human disease. This review focuses on PAX5 loss-of-function and summarizes techniques of murine model generation, available GEMMs, which mimic Pax5 loss-of-function in leukemia development and discusses the challenges and drawbacks of these models. These aspects are discussed in the context of creating a robust model, which serves not only for validation of the relevance of a genomic alteration in pB-ALL but at the same time as a valid preclinical model.
