Determination Of Catecholamine Content Changes In Mouse Brain Following Chronic Ketogenic Diet, Ryan Adams
Determination Of Catecholamine Content Changes In Mouse Brain Following Chronic Ketogenic Diet, Ryan Adams
Senior Theses and Projects
This work investigated the effects of the ketogenic diet on catecholamine concentrations in the brains of mice. The ketogenic diet has been show to modulate the catecholamine concentrations in the cerebrospinal fluid of children as well as altering hippocampal norepinephrine levels in mice. Tissue homogenates of the motor cortex, somatosensory cortex, nucleus accumbens, anterior caudate, posterior caudate and midbrain regions were analyzed using high pressure liquid chromatography to quantitate norepinephrine, dopamine, 3, 4-dihydroxyphenylacetic acid (DOPAC), 5-hydroxyindoleacetic acid (5HIAA), homovanillic acid (HVA) and serotonin (5-HT). No significant differences in catecholamine concentration levels were detected in the tissue homogenates. Analysis of metabolite …
The Investigation Of A Timp-1-Modulated Glial-Derived Factor Affecting Neuroblastoma Cell Death, Alexandra Nicaise
The Investigation Of A Timp-1-Modulated Glial-Derived Factor Affecting Neuroblastoma Cell Death, Alexandra Nicaise
Senior Theses and Projects
The original role of astrocytes was believed to have been as a neuronal-supportive cell in the brain. It has now been discovered that they play imperative roles, from reuptake of neurotransmitters from the extracelluar space to signal propagation and developmental control by the release of factors into the extracellular space. SH-SY5Y and IMR-32 cells are common neuroblastoma cell lines which model cancerous brain cells when left undifferentiated. In recent studies tissue inhibitors of metalloproteinases (TIMPs) have been implicated in neurodegenerative diseases, but their exact role in cell death is unknown. A double-blind cell culture experiment was conducted using astrocytes from …
