High Resolution Respirometry in Candida albicans
[Abstract] Many Candida species, such as the opportunistic human pathogen Candida albicans, are Crabtree-Negative yeasts and are therefore highly dependent on the energy generated through oxidative phosphorylation. Respiration control is linked to a range of aspects of C. albicans cell physiology that appear to be important for ...
Fluorescence HPLC Analysis of the in-vivo Activity of Glucosylceramide Synthase
[Abstract] Almost all functions of cells or organs rely on the activities of cellular enzymes. Indeed, the in-vivo activities that directly represent the cellular effects of enzymes in live organs are critical importance to appreciate the roles enzymes play in modulating physiological or pathological processes, although assessments of such in-vivo ...
Murine Pharmacokinetic Studies
[Abstract] Murine pharmacokinetics (PK) represents the absorption, distribution, metabolism, and elimination of drugs from the body, which helps to guide clinical studies, ultimately resulting in more effective drug treatment. The purpose of this protocol is to describe a serial bleeding protocol, obtaining blood samples at six time points from single mouse ...
Using Stable Isotopes in Bone Marrow Derived Macrophage to Analyze Metabolism
[Abstract] Using gas chromatography mass spectrometry (GC-MS) to analyze the citric acid cycle (CAC) and related intermediates (such as glutamate, glutamine, GABA, and aspartate) is an analytical approach to identify unexpected correlations between apparently related and unrelated pathways of energy metabolism. Intermediates can be as expressed as their ...
Preparation of Lipid-Stripped Serum for the Study of Lipid Metabolism in Cell Culture
[Abstract] Studying lipid metabolism in cultured cells is complicated by the fact that cells are typically cultured in the presence of animal serum, which contains a wide, variable, and undefined variety of lipid species. Lipid metabolism can impact cell physiology, signaling, and proliferation, and the ability to culture cells in the absence of exogenous ...
