Frontotemporal dementia (FTD) is an early onset dementia and is characterized by progressive atrophy of the frontal and/or temporal lobes. FTD is highly heritable with mutations in progranulin accounting for 5-26% of cases in different populations. Progranulin is involved in endocytosis, secretion and lysosomal processes, but its function under physiological and pathological conditions remains to be defined. Many FTD-causing nonsense progranulin mutations contain a premature termination codon (PTC), thus progranulin haploinsufficiency has been proposed as a major disease mechanism. Currently, there is no effective FTD treatment or therapy.
Aminoglycosides are a class of antibiotics that possess a less known function …
Epigenetic Implications In Inorganic Arsenic-Mediated Carcinogenesis, Meredith Eckstein
Epigenetic Implications In Inorganic Arsenic-Mediated Carcinogenesis, Meredith Eckstein
Theses and Dissertations--Molecular and Cellular Biochemistry
Chronic, low dose exposure to inorganic arsenic (iAs) is a public health concern throughout the world, contributing to the development of many diseases, including lung cancer. Several mechanisms for iAs-mediated carcinogenesis have been proposed, of which the production of reactive oxygen species and formation of chromosomal aberrations are the most studied. Another equally important, yet less studied mechanism is dysregulation of epigenetic marks. “Epigenetics” refers to changes that occur on the DNA and chromatin that do not alter base pair identity, but alter compaction, expression, and regulation of specific DNA sequences. There are several types of epigenetic marks including histone …

Apoe As A Metabolic Regulator In Humans, Mice, And Astrocytes, Brandon C. Farmer
Theses and Dissertations--Physiology
Altered metabolic pathways appear to play central roles in the pathophysiology of late-onset Alzheimer’s disease (AD). Carrier status of the E4 allele of the APOE gene is the strongest genetic risk factor for late-onset AD, and increasing evidence suggests that E4 carriers may be at an increased risk for neurodegeneration based on inherent metabolic impairments. A new appreciation is forming for the role of APOE in cerebral metabolism, and how nutritional factors may impact this role. In chapter 1, the literature on nutritional interventions in E4 carriers aimed at mitigating disease risk is reviewed. Studies investigating the mechanism by which …
