Neurodegenerative Modeling: Tau Protein, Degradative Pathways, And Gene Expression Profiling Of Human Ipsc-Derived Neural Precursors And Differentiated 3-D Neural Sphere Versus 2-D Monolayer Cultures, Kyle H. Anthoney
Cal Poly Humboldt theses and projects
Human induced pluripotent stem cells offer a model for human brain development and disease by differentiation into brain organoids; however, current neural culture systems lack the microenvironment, neuronal circuits and connectivity, vascular circulation, and immune system that exist in vivo. After differentiation and development of neuronal and non-neuronal cell types within two formats of cell cultures, we can visualize and recapitulate in vivo protein accumulation, gene expression, and degradative processes such as autophagy. Using RNA extraction, purification methods and reverse transcription I compared traditional monolayer cultures and novel 3-D neural sphere cultures via gene expression analysis. This analysis indicated …
Characterizing The Effect Of Cjun On The Expression Of Oct4 Variants And How They Correlate With The Expression Of Genes Associated With Potency And Cell Fate Of Murine Embryonic Stem Cells, Kristine Teague
Cal Poly Humboldt theses and projects
cJun is a transcription factor associated with proliferation and growth. Recent evidence has shown it plays a role in cell fate decision making of embryonic stem cells and correlates with changes in Oct4 expression, an important marker for pluripotency. There are multiple Oct4 isoforms that arise from alternative splicing and alternative translation. Oct4A is the variant most frequently associated with pluripotency, while evidence suggests that Oct4B variants have roles in potency as well as stress responses.
We aimed to study the effect of cJun over expression in murine embryonic stem cells on Oct4 gene expression through two methods: transient transfection …
