Metabolic Preconditioning Of Mammalian Cells: Mimetic Agents For Hypoxia Lack Fidelity In Promoting Phosphorylation Of Pyruvate Dehydrogenase, Apurva Borcar, Michael A. Menze, Mehmet Toner, Steven C. Hand

Faculty Research & Creative Activity

Induction of HIF-1α by oxygen limitation promotes increased phosphorylation and catalytic depression of mitochondrial pyruvate dehydrogenase (PDH) and an enhanced glycolytic poise in cells. Cobalt chloride and desferrioxamine are widely used as mimics for hypoxia because they increase the levels of HIF-1α. We evaluated the ability of these agents to elicit selected physiological responses to hypoxia as a means to metabolically precondition mammalian cells, but without the detrimental effects of hypoxia. We show that, while CoCl2 does increase HIF-1α in a dose-dependent manner, it unexpectedly and strikingly decreases PDH phosphorylation at E1α sites 1, 2, and 3 (Ser293, Ser300, and …

Association Between Physical Activity Resource Quality And Use In Mexicans Through Objective Observation, Ann Pacheco, Erica Soltero, Scherezade K. Mama, Rebecca E. Lee

International Journal of Exercise Science: Conference Proceedings

Purpose: Nearly three-fourths (69.5%) of the Mexican population aged 15 and older is overweight or obese, and 37.7% fail to meet physical activity (PA) recommendations of 150 minutes per week. The prevalence of obesity in Mexican children has tripled since 1980 and is due to the imbalance between energy intake and expenditure. PA may reduce the prevalence of obesity in Mexican adults and youth. PA resources (PARs), such as parks and plazas, may aid in this effort, but little is known about the quality of resources in Mexico and their relationship to PA levels in adults and youth. The purpose …
