Qki-Mediated Cholesterol Biosynthesis In Eye Lens And Myelin Of The Central Nervous System, Seula Shin, Seula Shin
Qki-Mediated Cholesterol Biosynthesis In Eye Lens And Myelin Of The Central Nervous System, Seula Shin, Seula Shin
Dissertations & Theses (Open Access)
Cells obtain cholesterol in two ways, de novo biosynthesis and uptake from circulation. While most tissues utilize both sources, eye lens and brain depend extensively on cholesterol biosynthesis due to the limited supply from circulation. Lens cell membrane consists of highest portion of cholesterol. Brain is the most cholesterol-rich organ, which accounts for 23% of total cholesterol. Genetic mutations of cholesterol biosynthesis enzymes in humans and animal models present cataracts and hypomyelinating disorders linked to neurological impairment. Yet, it remains unclear how gene expression of cholesterol biosynthesis is regulated in lens and brain. Therefore, studying cholesterol biosynthesis in both tissues …

Amino Acid Sensing Ability By The Mechanistic Target Of Rapamycin In Oligodendrocytes, Emma England
Senior Theses and Projects
Oligodendrocytes (OLs) are a type of glial cell in the central nervous system that require substantial nutrients such as lipids and amino acids to create the extensive, metabolically expensive myelin sheath surrounding the axons of neurons. The mammalian target of rapamycin (mTOR) is a regulatory kinase that is necessary for the maturation of progenitor OLs through their distinct oligo-lineage phases. Amino acids are vital for the functioning of cells. The focus of this study was to determine if mTOR activity is dependent on the availability of leucine, methionine, and alanine. This was assessed by examining the phosphorylation level of the …
