C-Rel Is A Transcriptional Target Of Mesoderm Inducer In Xenopus Like 1 (Mixl1), Aaron C. Raymond

Dissertations & Theses (Open Access)

MIXL1, an evolutionarily conserved, paired-type homeobox transcription factor induced by BMP4/TGFb signaling, is a critical regulator of embryonic and adult hematopoiesis. Several lines of evidence implicate MIXL1 in hematopoietic transformation: (i) Aberrant MIXL1 expression is seen in human CML ( Chronic Myelogenous Leukemia) in blast crisis, AML (Acute myelogenous leukemia), B cell lymphomas and pediatric ALL (Acute lymphocytic leukemia). (ii) Retroviral transduction of Mixl1 induces AML in murine models. Nonetheless, mechanisms underlying MIXL1 mediated proliferative, survival advantages are unknown.

The goal of my studies is to understand if and how aberrant MIXL1 expression contributes to leukemogenesis. As a first step, …

Prkca: Identification Of A Novel Downstream Target Of Wt1, Devin Jones

Dissertations & Theses (Open Access)

Wilms tumor is a childhood tumor of the kidney arising from the undifferentiated metanephric mesenchyme. Tumorigenesis is attributed to a number of genetic and epigenetic alterations. In 20% of Wilms tumors, Wilms tumor gene 1 (WT1) undergoes inactivating homozygous mutations causing loss of function of the zinc finger transcription factor it encodes. It is hypothesized that mutations in WT1 result in dysregulation of downstream target genes, leading to aberrant kidney development and/or Wilms tumor. These downstream target genes are largely unknown, and identification is important for further understanding Wilms tumor development. Heatmap data of human Wilms tumor protein …
