    Immunoprecipitation of Acetyl-lysine and Western Blotting of Long-chain acyl-CoA Dehydrogenases and Beta-hydroxyacyl-CoA Dehydrogenase in Palmitic Acid Treated Human Renal Tubular Epithelial Cells
    Authors:  Tingting Lv, Suwei Zhu, Yuan Ma, Hong Feng and Qiang Wan, date: 09/20/2020, view: 1253, Q&A: 0
    [Abstract] As one of the main energy metabolism organs, kidney has been proved to have high energy requirements and are more inclined to fatty acid metabolism as the main energy source. Long-chain acyl-CoA dehydrogenases (LCAD) and beta-hydroxyacyl-CoA dehydrogenase (beta-HAD), key enzymes involved in fatty acid oxidation, has been identified as the ...
    Metabolomic and Lipidomic Analysis of Bone Marrow Derived Macrophages
    Authors:  Gretchen L. Seim, Steven V. John and Jing Fan, date: 07/20/2020, view: 1282, Q&A: 0
    [Abstract] Macrophages are highly plastic immune cells that are capable of adopting a wide array of functional phenotypes in response to environmental stimuli. The changes in macrophage function are often supported and regulated by changes in cellular metabolism. Capturing a comprehensive picture of metabolism is vital for understanding the role of metabolic ...
    Observing Nutrient Gradients, Gene Expression and Growth Variation Using the "Yeast Machine" Microfluidic Device
    [Abstract] The natural environment of microbial cells like bacteria and yeast is often a complex community in which growth and internal organization reflect morphogenetic processes and interactions that are dependent on spatial position and time. While most of research is performed in simple homogeneous environments (e.g., bulk liquid cultures), ...
    Isolation of Lipid Rafts from Cultured Mammalian Cells and Their Lipidomics Analysis
    Authors:  Nigora Mukhamedova, Kevin Huynh, Hann Low, Peter J. Meikle and Dmitri Sviridov, date: 07/05/2020, view: 1340, Q&A: 0
    [Abstract] Lipid rafts are distinct liquid-ordered domains of plasma membranes of most eukaryotic cells providing platform for signaling pathways. Lipid composition of rafts is critical for their structural integrity and for regulation of signaling pathways originating from rafts. Here we provide a protocol to isolate lipid rafts from cultured human and ...
    Gas Chromatography Detection Protocol of Short-chain Fatty Acids in Mice Feces
    Authors:  Chaozheng Zhang, An Liu, Tianshuang Zhang, Yi Li and Hua Zhao, date: 07/05/2020, view: 1195, Q&A: 0
    [Abstract] Short-chain fatty acids (SCFAs), which are formed mainly by bacteria fermenting undigested carbohydrates in the colon, they are based on the number of carbon atoms in the carbon chain. Organic fatty acids with less than 6 carbon atoms are called short-chain fatty acids. SCFAs are closely related to various aspects of the human body, so more and ...
    Isolation of Tumor Cells Based on Their Distance from Blood Vessels
    Authors:  Saran Kumar, Husni Sharife, Tirzah Kreisel, Libat Bar-Lev, Myriam Grunewald and Eli Keshet, date: 05/20/2020, view: 1732, Q&A: 0
    [Abstract] Differential exposure of tumor cells to microenvironmental cues greatly impacts cell phenotypes, raising a need for position based sorting of tumor cells amenable to multiple OMICs and functional analyses. One such key determinant of tumor heterogeneity in solid tumors is its vasculature. Proximity to blood vessels (BVs) profoundly affects tumor ...
    Pancreatic Acinar Cell Preparation for Oxygen Consumption and Lactate Production Analysis
    Authors:  Jane A. Armstrong, Robert Sutton and David N. Criddle, date: 05/20/2020, view: 1192, Q&A: 0
    [Abstract] Mitochondrial dysfunction is a principal feature of acute pancreatitis (AP) although the underlying mechanisms are still unclear. AP precipitants induce Ca2+-dependent formation of the mitochondrial permeability transition pore (MPTP) in pancreatic acinar cells (PACs), leading to ATP depletion and necrosis. Evaluations of mitochondrial ...
    Spectrophotometric Assessment of Heme Oxygenase-1 Activity in Leishmania-infected Macrophages
    Authors:  Moumita Basu, Shriya Saha and Anindita Ukil, date: 04/05/2020, view: 1416, Q&A: 0
    [Abstract] Heme oxygenase-1 (HO-1) is a stress responsive enzyme that metabolizes heme and releases free iron, carbon monoxide (CO), and biliverdin (BV), which rapidly undergoes conversion to bilirubin (BL). Estimation of bilirubin is the basis of HO-1 assay. HO-1 activity is widely employed to determine antioxidant response of cells under different ...
    Steady-state and Flux-based Trehalose Estimation as an Indicator of Carbon Flow from Gluconeogenesis or Glycolysis
    Authors:  Ritu Gupta and Sunil Laxman, date: 01/05/2020, view: 1891, Q&A: 0
    [Abstract] Trehalose (and glycogen) is a major storage carbohydrate in many cells, including S. cerevisiae. Typically, trehalose (a disaccharide of glucose) is synthesized and stored through gluconeogenesis. However, trehalose can also be made directly from glucose, if glucose-6-phosphate is channeled away from glycolysis or pentose phosphate ...
    High Resolution Respirometry in Candida albicans
    Authors:  Lucian Duvenage, Carol A. Munro and Campbell W. Gourlay, date: 09/05/2019, view: 1988, Q&A: 0
    [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 ...
