Identification Of Substrate-Selective Histone Deacetylases And Their Inhibitors That Mediate Her2 Transcript Stability, Mariah Alejo May 2018

Identification Of Substrate-Selective Histone Deacetylases And Their Inhibitors That Mediate Her2 Transcript Stability, Mariah Alejo

Breast cancer is the most common malignancy diagnosed in women. 15-20% of these cancers overexpress the HER2 (ERRB2) oncoprotein. HER2-positive breast cancers are generally aggressive and are associated with poor prognosis. Unfortunately, only a mere 30% of HER2-positve patients respond to therapies when they are used as a single agent. Combining therapeutics can potentially lead to synergy and improved anticancer efficacy, and there is clearly a need for the development of new HER2-directed therapeutics. Newer approaches include the utilization of histone deacetylase (HDAC) inhibitors. It has been observed that HDAC inhibitors can induce the rapid decay of oncogenic transcripts such …


Efficient In Vitro Development Of Photoreceptors From Human Pluripotent Stem Cells, Joseph C. Reynolds May 2015

Degeneration of the rod and cone photoreceptors in the human retina is among the most common causes of blindness. Replacing these damaged photoreceptors may help to restore vision. Repairing the damaged retina relies on the insertion of new, healthy cells. Embryonic stem (ES) cells and induced pluripotent stem (iPS) cells are two possible sources of photoreceptors to restore vision. Previous data shows that human ES cells and iPS cells can be differentiated into photoreceptors and transplanted into the eye to restore some vision. However, this process is inefficient, and costly. Here, we show a new method for inducing photoreceptor production …


Neural Stem Cells As A Model To Study Huntington’S Disease, Rawan Bakhsh Nov 2014

Neural Stem Cells As A Model To Study Huntington’S Disease, Rawan Bakhsh

Dissertations, Masters Theses, Capstones, and Culminating Projects

Huntington’s disease (HD) is a heritable neurodegenerative disorder that affects muscle coordination and diminishes cognitive abilities, by affecting the medium spiny neurons in the brain. In HD patients, neurons are damaged and destroyed because of the toxicity of the mutant Huntington protein (mHtt). The mechanism of how mHtt protein affects the neurons is unknown. In this study we explored the effects of mHtt expression by looking at changes in huntingtin localization, changes in the expression and co-localization of related proteins and differences in cell morphology. We examine how this expression affects the cytoskeletal structures using neural stem cells Q7 (wild …
