Non-Invasive Determination Of Pre-Clinical Markers Of Cardiovascular Diseases In Low Birth Weight And Maternal Western Diet Guinea Pig Offspring Exposed To A Postnatal Western Diet, Jacky Chiu
Electronic Thesis and Dissertation Repository
Low birth weight (LBW), and maternal Western Diet (WD) consumption have both been independently implicated to increase the risk of developing cardiovascular diseases (CVDs) in later life. These fetal programmed risks are also believed to exacerbate the effects of a postnatal WD pattern. Therefore, resulting in the development of pre-clinical markers of CVDs, such as insulin resistance (IR), coronary circulation disruptions. This thesis aimed to elucidate the roles of sub-optimal in utero growth through placental insufficiency, or chronic maternal WD consumption, and postnatal WD consumption on the long-term programming of CVDs in a guinea pig model. Early pre-clinical markers of …

Skeletal Muscle Lipid Metabolism And Markers Of Insulin Resistance In Young Male Low Birth Weight Offspring In Combination With A Postnatal Western Diet, Kristyn Pamela Dunlop
Electronic Thesis and Dissertation Repository
Low birth weight offspring are at increased risk for developing metabolic syndrome in later life, specifically its precursor, insulin resistance (IR). Reduced mitochondrial lipid metabolism is implicated in IR pathogenesis, promoting accumulation of acylcarnitines, and potentiating alterations in phosphorylation status of insulin signaling intermediates. While high-energy Western diets are classically implicated in IR progression, the in utero environment was recently highlighted as a major programming mechanism of later life IR. Using a guinea pig model of placental insufficiency, we investigated how an adverse in utero environment impacts later life mitochondrial lipid metabolism and IR progression, as well as its interaction …
