Ribonucleotide Reductase Subunit Switching In Hepatoblastoma Drug Response And Relapse, Anthony Brown
Ribonucleotide Reductase Subunit Switching In Hepatoblastoma Drug Response And Relapse, Anthony Brown
Theses and Dissertations (ETD)
Hepatoblastoma is the most common primary liver cancer in infants and young children. Despite being a very rare cancer that accounts for only 0.5-2% if all childhood cancer cases, HB has the largest increase in incidence among childhood cancers in the United States and worldwide. The five-year survival rate of children with the aggressive forms of HB, including those that have developed metastatic or recurrent diseases, is less than 40% due to the lack of effective treatment. We aim to identify targetable mechanisms underlying the progression and drug resistance of high-risk HB. Our recent work on HB mouse and organoid …

Triple negative breast cancer (TNBC) is aggressive but cannot be treated with hormone therapy or molecular therapy due to the lack of a target. Chemotherapy is a systemic treatment that works by attacking rapidly growing cells, which is initially more effective for TNBC patients than those individuals with the hormone receptor-positive breast cancer. However, patients with TNBC tend to develop resistance to chemo drugs, called chemoresistance. After years of effort, the signaling pathways involved in TNBC chemoresistance are gradually revealed, including the nuclear factor-kappa B (NF-kB) pathway. Transcription factor NF-kB is widely involved in cancer development and progression, and its …
The Role And Immunogenicity Of Cbfa2t3-Glis2 In Pediatric Acute Megakaryoblastic Leukemia, Elizabeth A. Garfinkle
The Role And Immunogenicity Of Cbfa2t3-Glis2 In Pediatric Acute Megakaryoblastic Leukemia, Elizabeth A. Garfinkle
Theses and Dissertations (ETD)
CBFA2T3-GLIS2 is the most prevalent fusion oncogene in pediatric acute megakaryoblastic leukemia in patients without Down syndrome (non-DS-AMKL) and is associated with an event free survival of only 8% even with high intensity chemotherapy and stem cell transplant in first remission. A cryptic inversion event on chromosome 16 joins the three nervy homology regions (NHR) of CBFA2T3 to the five zinc fingers of GLIS2. This configuration enables the encoded chimeric transcription factor to bind GLIS consensus sequences throughout the genome and recruit transcriptional activators and repressors to alter gene expression and enhance self-renewal capability. Few cooperating mutations have been identified …
Targeting Myeloid Protein Kinase C Signaling To Overcome Immune Suppression And Improve Immunotherapy In Cancer, Mehdi Chaib
Targeting Myeloid Protein Kinase C Signaling To Overcome Immune Suppression And Improve Immunotherapy In Cancer, Mehdi Chaib
Theses and Dissertations (ETD)
Checkpoint immunotherapy unleashes T cell antitumor potential which has revolutionized cancer treatment showing unprecedented long-term responses. However, most patients do not respond to immunotherapy which often correlates with a dysfunctional or immunosuppressive myeloid compartment. Immunosuppressive myeloid cells comprise Myeloid-derived suppressor cells (MDSCs) and tumor-associated macrophages (TAMs) and can suppress T cells via production of immunosuppressive factors. Conversely, efficient cytotoxic T cell priming is dependent on the ability of antigen-presenting cells (APCs), mainly conventional dendritic cells (cDCs) and macrophages, to present or cross-present tumor antigens to T cells. Thus, targeting immunosuppressive myeloid cells while simultaneously enhancing APCs represents a promising strategy …

Acute Lymphoblastic Leukemia (ALL), the most common childhood cancer and the second most common acute leukemia in adults, arises from clonal expansion of undifferentiated lymphoid precursor cells in bone marrow. Despite the extensive knowledge on its cytogenetic and molecular biology, ALL treatment remains highly challenging especially after relapse. Conventional chemotherapy has shown significant improvement in overall survival rates of pediatric patients up to 90%, however, treatment failure due to ALL relapse occurs in 15-20% of the cases. On the other hand, adults and elderly patients with ALL are considered difficult to treat populations with the 5-year overall survival of 30–40%. …
