Molecular And Therapeutic Implications Of Notch1 Signaling In Pediatric T-Cell Acute Lymphoblastic Leukemia, Amanda Larson Gedman

Wayne State University Dissertations

T-cell acute lymphoblastic leukemia (T-ALL) accounts for 15% of pediatric ALL cases and is associated with early relapse and inferior outcome. The poorer prognosis of T-ALL compared to B-precursor ALL may in part reflect the lack of unique features on which to base therapy. NOTCH1 mutations are of particular interest since these were reported in 37-71% of T-ALLs. The prognostic value of NOTCH1 mutations remains controversial as both favorable and unfavorable associations were reported, whereas in other studies, there were no associations between NOTCH1 mutations and treatment outcome. We explored the impact of mutations in NOTCH1, FBW7 and PTEN on …
