Biochemical Changes In Animal Models Of Fetal Alcohol Spectrum Disorder, Christine E. M. Keller
Biochemical Changes In Animal Models Of Fetal Alcohol Spectrum Disorder, Christine E. M. Keller
Open Access Dissertations
Fetal alcohol spectrum disorder (FASD) is a completely preventable disease, that has profound effects on life-long health and function of the affected individual. Prevalence estimates of FASD in the United States indicate 33.5 per 1,000 live births are affected with this disorder (Roozen, 2016). FASD is caused by maternal ethanol intake during pregnancy. However, recommendations of the amounts of alcohol safe to drink during pregnancy are not established. Further, we lack a comprehensive understanding of the biochemical pathways modified in prenatal ethanol exposure. Biomarkers are also lacking. Our results demonstrate the vast array of biochemical pathways modified in the chronic …

Hedgehog (Hh) signaling regulates multiple aspects of metazoan development and tissue homeostasis, and is constitutively active in numerous cancers. We identified Ubr3, an E3 ubiquitin ligase, as a novel, positive regulator of Hh signaling in Drosophila and vertebrates. Hh signaling regulates the Ubr3-mediated poly-ubiquitination and degradation of Cos2, a central component of Hh signaling. In developing Drosophila eye discs, loss of ubr3 leads to a delayed differentiation of photoreceptors and a reduction in Hh signaling. In zebrafish, loss of Ubr3 causes a decrease in Shh signaling in the developing eyes, somites, and sensory neurons. However, not all tissues that require …

Hematopoiesis culminates in the production of functionally heterogeneous blood cell types. In zebrafish, the lack of cell surface antibodies has compelled researchers to use fluorescent transgenic reporter lines to label specific blood cell fractions. However, these approaches are limited by the availability of transgenic lines and fluorescent protein combinations that can be distinguished. Here, we have transcriptionally profiled single hematopoietic cells from zebrafish to define erythroid, myeloid, B, and T cell lineages. We also used our approach to identify hematopoietic stem and progenitor cells and a novel NK-lysin 4+ cell type, representing a putative cytotoxic T/NK cell. Our platform …

Amyotrophic Lateral Sclerosis (ALS) is a terminal neurodegenerative disease
with symptoms including limb-onset muscle wasting, difficulties swallowing and breathing, leading to death. Sporadic ALS occurs in 90% of patients, while 10% of cases are familial (FALS). Twenty percent of FALS cases are a result of mutation in the copper-zinc superoxide dismutase (SOD1) gene, leading to the activation of the mitochondrial apoptosis pathway. Meanwhile, a prominent cause of sporadic ALS is exposure to neurotoxins, such as β-methylamino-L-alanine (BMAA). BMAA has been suggested to induce selective motor neuron death, which is observed in ALS patients. While research has been done to how …

Cancers contain a wide diversity of cell types that are defined by differentiation states, genetic mutations and altered epigenetic programmes that impart functional diversity to individual cells. Elevated tumour cell heterogeneity is linked with progression, therapy resistance and relapse. Yet, imaging of tumour cell heterogeneity and the hallmarks of cancer has been a technical and biological challenge. Here we develop optically clear immune-compromised rag2E450fs (casper) zebrafish for optimized cell transplantation and direct visualization of fluorescently labelled cancer cells at single-cell resolution. Tumour engraftment permits dynamic imaging of neovascularization, niche partitioning of tumour-propagating cells in embryonal rhabdomyosarcoma, emergence of clonal …
