Identifying The Cell Composition And Clonal Diversity Of Supratentorial Ependymoma Using Single Cell Rna-Sequencing, James He May 2021

Identifying The Cell Composition And Clonal Diversity Of Supratentorial Ependymoma Using Single Cell Rna-Sequencing, James He

University Scholar Projects

Ependymoma is a primary solid tumor of the central nervous system. Supratentorial ependymoma (ST-EPN), a subtype of ependymomas, is driven by an oncogenic fusion between the ZFTA and RELA genes in 70% of cases. We introduced this fusion into neural progenitor cells of mice embryos via in utero electroporation of a non-viral binary piggyBac transposon system containing ZFTA-RELA. From preliminary data in the LoTurco lab, inducing the expression of ZFTA-RELA into different neural progenitor cells produces tumors of varying lethality and cellular composition. To define the cellular composition and subclonal diversity of ST-EPN tumors, we used single cell RNA-sequencing to …


The Effects Of Mapk Signaling On The Development Of Cerebellar Granule Cells, Kerry Morgan May 2021

The Effects Of Mapk Signaling On The Development Of Cerebellar Granule Cells, Kerry Morgan

University Scholar Projects

The granule cells are the most abundant neuronal type in the human brain. Rapid proliferation of granule cell progenitors results in dramatic expansion and folding of the cerebellar cortex during postnatal development. Mis-regulation of this proliferation process causes medulloblastoma, the most prevalent childhood brain tumor. In the developing cerebellum, granule cells are derived from Atoh1-expressing cells, which arise from the upper rhombic lip (the interface between the roof plate and neuroepithelium). In addition to granule cells, the Atoh1 lineage also gives rise to different types of neurons including cerebellar nuclei neurons. In the current study, I have investigated the …

Use Of Antisense Oligonucleotides To Target Notch2 In Mouse Chondrocytes, Gabrielle Viviana Lanza Apr 2021

Use Of Antisense Oligonucleotides To Target Notch2 In Mouse Chondrocytes, Gabrielle Viviana Lanza

Honors Scholar Theses

NOTCH2 is a transmembrane receptor that is part of the Notch receptor family, known for controlling cell differentiation and function. Notch receptors play a crucial role in skeletal development and bone homeostasis. Hajdu Cheney Syndrome (HCS) is a rare monogenic disorder affecting the skeleton caused by a gain-of-function mutation in NOTCH2. Antisense oligonucleotides (ASO) are sequence-specific single-stranded nucleic acids that bind to target mRNA and initiate mRNA degradation. While previous work has explored the role of Notch2 ASOs in osteoblasts and osteoclasts, this paper explores the role of Notch2 and Notch2 ASOs in cells of cartilage tissue. The effect of …


The Emerging Role Of Pancreatic Β-Cell Primary Cilia In Diabetes Mellitus, Emily Blackburn Apr 2021

The Emerging Role Of Pancreatic Β-Cell Primary Cilia In Diabetes Mellitus, Emily Blackburn

Honors Scholar Theses

Diabetes mellitus is prevalent in America, affecting more than 10% of the population. The underlying cause of the disease are diverse and can be related to genes, environment and physical inactivity. This review investigates how a minute cellular organelle called primary cilium, found in pancreatic β-cells, affects the development and the function of the pancreas. Gene mutations related to primary cilia can lead to malfunctions or loss of the structure, and cause diseases collectively classified as ciliopathies. Recent studies of two types of ciliopathies, Alstrom’s Syndrome and Bardet–Biedl Syndrome, connect the primary cilium defects with insulin secretion in pancreatic β-cells. …
