Zebrafish Model Of Mll-Rearranged Acute Myeloid Leukemia, Alex J. Belt

Theses and Dissertations

Acute myeloid leukemia (AML) is the second most common type of leukemia and accounts for 80% of adult acute leukemia cases and is characterized by the accumulation of poorly or undifferentiated myeloid blast cells. Standard treatment includes chemotherapy, which if unsuccessful, is followed by more rigorous chemotherapy as well as stem cell transplantation. Considering most patients are over the age of 45, these more rigorous therapies are not always possible, and as such, new therapies must be developed. Furthermore, AML patients harboring a chromosomal rearrangement involving Multiple Lineage Leukemia (MLL) that results in the expression of an MLL fusion protein …

Critical Functions Specified By The Mll Cxxc Domain Determine Leukemogenic Capacity, Noah Warren Birch

Dissertations

TheMixed Lineage Leukemia(MLL) gene can participate in chromosomal translocations which generate a fusion protein leading to acute leukemia. A better understanding of how MLL fusion proteins contribute to leukemia is necessary in order to develop more effective treatments. In my dissertation project, I investigated the functional role of amino acids within the MLL CXXC domain to determine how specific residues contribute to leukemogenic capacity.

MLL fusion proteins retain the amino-terminal portion of MLL including the CXXC DNA-binding domain while the carboxy-terminal portion is comprised of a fusion partner. The closest homolog of MLL, MLL2 (alternatively named MLL4), also contains a …

Role Of Non-Coding Rna Nc4 In Mll And Cyp33 Mediated Regulation Of Hoxc8, Jessica Arvindbhai Solanki

Dissertations

MLL or Mixed Lineage Leukemia gene is clinically known for its involvement in genetic translocation with more than 70 different partners identified each giving rise to a highly leukemogenic fusion protein. With a poor prognosis of MLL related leukemia, an investigation into its role during hematopoiesis has been a very active field of research. In order to design strategies to combat the MLL leukemia, it becomes essential to delineate the molecular mechanisms behind the function of MLL wild type protein. Wild type MLL is a transcriptional maintenance protein from the Trithorax Group (TrxG) that resides in complex with other chromatin …
