Molecular And Cellular Investigations Of Prader-Willi Syndrome, Anna K. Victor
Molecular And Cellular Investigations Of Prader-Willi Syndrome, Anna K. Victor
Theses and Dissertations (ETD)
Prader-Willi syndrome (PWS) is a complex multigenic neurodevelopmental disorder resulting in hypotonia, developmental delay, hypogonadism, sleep dysfunction and childhood onset obesity affecting 1 in 10,000 to 30,000 individuals. PWS is an imprinting disorder that is caused by a loss of expression of maternally imprinted genes in the 15q11.2-q13 region including NDN, MAGEL2, SNRPN/SNURF, and a cluster of snoRNAs. The majority of cases are caused by inheriting a paternal allele deletion of this region (65-75%) and a smaller number are caused by chromosome 15 maternal uniparental disomy (UPD) (20-30%) or imprinting center defects (1-3%). Here, we used dental pulp stem cells …

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 …
