Genetic studies have identified a number of genes that when mutated predispose individuals to blood cancers. In addition, these mutations can promote other health complications throughout their lifetime. For example, children that inherit a mutation in the gene RUNX1 have Familial Platelet Disorder, they live with bleeding problems and, in many cases, autoimmune complications. In addition, affected children have a high incidence of blood cancer during their childhood or later in life. Currently, there are not effective therapies to prevent the development of blood cancer.

The molecular mechanisms responsible for the pathology of familial platelet disorder and predisposition to leukemia are poorly understood. This understanding is essential for the development of effective therapies that can preempt leukemia transformation. Fortunately, a number of approaches are being developed to study these mechanisms in cell base assays. However, there are no good animal models that mimic the disease mutations. We are developing mouse strains with four FPD-associated mutations in the Runx1 gene, mimicking mutations found in FPD patients.

Lay Summary: Endemic Burkitt lymphoma (eBL) is the most common childhood cancer in Africa. This cancer is treatable with chemotherapy, but the survival rate for African children is 50%, in contrast to 90% survival for American children. This could be due to two common childhood infections that are considered risk factors for eBL, namely malaria and Epstein­-Barr virus (EBV). A healthy immune system is able to recognize and kill human cells that have become infected or have become cancer cells.

Background

The treatment of childhood acute myeloid leukemia (AML) is based on the use of high dose chemotherapies, with significant toxicity and varied prognosis. The emergence of targeted therapy strategies in cancer treatment has enlightened the hope for developing new drugs with higher potency and reduced toxicity in patients.

Background

Treatment protocols used in the treatment of pediatric acute myeloid leukemia (AML) are based on chemotherapy drugs, often resulting in side effects due to significant toxicity. In recent years, the emergence of targeted therapy strategies in cancer treatment has enlightened the hope for developing new drugs with higher potency and reduced toxicity in patients.

Background

Background


Acute myeloid leukemia is the most frequent myeloid neoplasia in pediatric cancers, and it develops from the accumulation of mutations in the blood stem cells in the bone marrow. A recurrent mutations is the chromosome inversion inv16(p13q22), which creates the fusion protein CBFbeta-SMMHC. This fusion plays an important role in the expansion and survival of the leukemic cells.
