Arsenic is a toxicant commonly found in water systems around the world. Evidence from epidemiological studies indicates that chronic arsenic exposure can result in cancer, central nervous system and sensory deficits, effects on development, and neuromuscular deficits. However, the molecular mechanism of arsenic's toxicity remains largely unclear. In this study, both C2C12 mouse myoblast cells and mouse embryonic stem cells (mESCs) were used as models of arsenic mediated developmental toxicity in humans to investigate the effects of sodium arsenite on cellular differentiation.
Results from our first and second studies indicate that exposure of 20nM sodium arsenite to C2C12 mouse myocyte …

Gabaergic Signaling To Adult-Generated Neurons In Hippocampus, Sean Markwardt
All ETDs from UAB
In the central nervous system of adult mammals, new neurons are produced throughout life in at least two regions, the subventricular zone and dentate gyrus of the hippocampus. New neurons in the SVZ migrate via the rostral migratory stream and eventually participate in adaptive olfactory processes. In the dentate gyrus, a variety of physiological functions for continued addition of neurons have been proposed, but its role in normal or pathological conditions remains largely unclear. Neurogenesis in the dentate gyrus consists of the stepwise process of generating fully functional granule cells (GCs) from adult neural stem cells. Regulation of neurogenesis can …

Studies have shown that there is a strong correlation between aging and neurodegenerative diseases. Aging is considered the number one risk factor to develop neuropathologies such as memory loss, senile dementia, Alzheimer's disease (AD), and Parkinson's disease. Neurodegenerative diseases tend to start during adulthood, and aggravate over time, making them difficult to prevent and to treat. In the Unites States, demographic studies by U.S. Bureau of the Census have determined that our aging population of >65 years is expected to increase from the present 35 million to 78 million in 2030. This would result, not only to an increase of …
