    [Abstract] Mycobacterium tuberculosis (Mtb) has evolved to assimilate fatty acids from its host. However, until recently, there was no reliable way to quantify fatty acid uptake by the bacteria during host cell infection. Here we describe a new method to quantify fatty acid uptake by intracellular bacilli. We infect macrophages with Mtb ...

    [Abstract] Sterols are essential lipids of most eukaryotic cells with multiple functions (structural, regulatory and developmental). Sterol profile of yeast cells is often determined during the studies of ergosterol synthesis mutants used to uncover a number of functions for various sterols in yeast cells. Molecular studies of ergosterol biosynthesis have ...
    Metabolite and Fatty Acid Analysis of Yeast Cells and Culture Supernatants
    Authors:  Liwei Chen and Wei Ning Chen, date: 09/05/2014, view: 13592, Q&A: 0
    [Abstract] Metabolite and fatty acid analysis play important roles in evaluating the metabolic state of microorganisms. To examine the growth state and metabolism response of cells to environmental stress or genetic modification, intracellular and extracellular metabolites including fatty acids are usually analyzed to help understand the cellular biochemical ...
    Metabolic Labeling of Yeast Sphingolipids with Radioactive D-erythro-[4,5-3H]dihydrosphingosine
    Authors:  Takefumi Karashima, Kentaro Kajiwara and Kouichi Funato, date: 08/20/2013, view: 7949, Q&A: 0
    [Abstract] Yeast sphingolipids can be metabolically labeled with exogenously added radioactive precursors. Here we describe a method to label ceramides and complex sphingolipids of Saccharomyces cerevisiae with a radioactive ceramide precursor, D-erythro-[4, 5-3H]dihydrosphingosine. This protocol is used to study the biosynthesis, ...
