Metabolism and Regulation of Glycerolipids in the Yeast Saccharomyces Cerevisiae
YEASTBOOK GENE EXPRESSION & METABOLISM Metabolism and Regulation of Glycerolipids in the Yeast Saccharomyces cerevisiae Susan A. Henry,*,1 Sepp D. Kohlwein,† and George M. Carman‡ *Department of Molecular Biology and Genetics, Cornell University, Ithaca, New York 14853, †Institute of Molecular Biosciences, University of Graz, A8010 Graz, Austria, and ‡Department of Food Science and Rutgers Center for Lipid Research, Rutgers University, New Brunswick, New Jersey 08901 ABSTRACT Due to its genetic tractability and increasing wealth of accessible data, the yeast Saccharomyces cerevisiae is a model system of choice for the study of the genetics, biochemistry, and cell biology of eukaryotic lipid metabolism. Glycerolipids (e.g., phospholipids and triacylglycerol) and their precursors are synthesized and metabolized by enzymes associated with the cytosol and membranous organelles, including endoplasmic reticulum, mitochondria, and lipid droplets. Genetic and biochemical analyses have revealed that glycerolipids play important roles in cell signaling, membrane trafficking, and anchoring of membrane proteins in addition to membrane structure. The expression of glycerolipid enzymes is controlled by a variety of conditions including growth stage and nutrient availability. Much of this regulation occurs at the transcriptional level and involves the Ino2–Ino4 activation complex and the Opi1 repressor, which interacts with Ino2 to attenuate transcriptional activation of UASINO-containing glycerolipid biosynthetic genes. Cellular levels of phosphatidic acid, precursor to all membrane phospholipids and the storage lipid triacylglycerol, regulates transcription of UASINO-containing genes by tethering Opi1 to the nuclear/endoplasmic reticulum membrane and controlling its translocation into the nucleus, a mechanism largely controlled by inositol availability. The transcriptional activator Zap1 controls the expression of some phospholipid synthesis genes in response to zinc availability. -

Hoffman 1,* 1 Exercise and Nutrition Research Program, Mary MacKillop Institute for Health Research, Australian Catholic University, Melbourne 3000, Australia; [email protected] 2 Australian National Phenome Centre, Health Futures Institute, Murdoch University, Harry Perkins Building, Murdoch, Perth 6150, Australia; [email protected] 3 School of Health and Medical Sciences, Edith Cowan University, Joondalup 6027, Australia * Correspondence: [email protected]; Tel.: +61-3-9230-8277 Abstract: Dynamic changes in circulating and tissue metabolites and lipids occur in response to exercise-induced cellular and whole-body energy demands to maintain metabolic homeostasis. The metabolome and lipidome in a given biological system provides a molecular snapshot of these rapid and complex metabolic perturbations. The application of metabolomics and lipidomics to map the metabolic responses to an acute bout of aerobic/endurance or resistance exercise has dramatically expanded over the past decade thanks to major analytical advancements, with most exercise-related studies to date focused on analyzing human biofluids and tissues. Experimental and analytical considerations, as well as complementary studies using animal model systems, are warranted to help overcome challenges associated with large human interindividual variability and decipher the breadth of molecular mechanisms underlying the metabolic health-promoting effects of exercise. In this review, we provide a guide for exercise researchers regarding analytical techniques and experimental workflows commonly used in metabolomics and lipidomics. Furthermore, we discuss Citation: Belhaj, M.R.; Lawler, N.G.; advancements in human and mammalian exercise research utilizing metabolomic and lipidomic Hoffman, N.J. -

Senevirathna 1,2,* and Shuichi Asakawa 1 1 Laboratory of Aquatic Molecular Biology and Biotechnology, Department of Aquatic Bioscience, Graduate School of Agricultural and Life Sciences, The University of Tokyo, Tokyo 113-8657, Japan; [email protected] 2 Department of Animal Science, Faculty of Animal Science and Export Agriculture, Uva Wellassa University, Badulla 90000, Sri Lanka * Correspondence: [email protected] Abstract: Lipid synthesis pathways of toothed whales have evolved since their movement from the terrestrial to marine environment. The synthesis and function of these endogenous lipids and affecting factors are still little understood. In this review, we focused on different omics approaches and techniques to investigate lipid metabolism and radiation impacts on lipids in toothed whales. The selected literature was screened, and capacities, possibilities, and future approaches for identify- ing unusual lipid synthesis pathways by omics were evaluated. Omics approaches were categorized into the four major disciplines: lipidomics, transcriptomics, genomics, and proteomics. Genomics and transcriptomics can together identify genes related to unique lipid synthesis. As lipids interact with proteins in the animal body, lipidomics, and proteomics can correlate by creating lipid-binding proteome maps to elucidate metabolism pathways. In lipidomics studies, recent mass spectroscopic methods can address lipid profiles; however, the determination of structures of lipids are challeng- ing. As an environmental stress, the acoustic radiation has a significant effect on the alteration of Citation: Senevirathna, J.D.M.; Asakawa, S. Multi-Omics Approaches lipid profiles.

Lipidomics in Health and Diseases
Mingming et al, J Glycomics Lipidomics 2015, 5:1 DOI: 10.4172/2153-0637.1000126 Journal of Glycomics & Lipidomics Review Article Open Access Lipidomics in Health and Diseases - Beyond the Analysis of Lipids Mingming Li, Pengcheng Fan and Yu Wang* State Key Laboratory of Pharmaceutical Biotechnology and Department of Pharmacology and Pharmacy, The University of Hong Kong, Hong Kong, China Abstract The role of lipids in human health and disease is taking the center stage. In the last decades, there has been an intense effort to develop suitable methodologies to discover, identify, and quantitatively monitor lipids in biological systems. Recent advancement of mass spectrometry technology has provided a variety of tools for global study of the lipid “Omes”, including the quantification of known lipid molecular species and the identification of novel lipids that possess pathophysiological functions. Lipidomics has thus emerged as a discipline for comprehensively illuminating lipids, lipid- derived mediators and lipid networks in body fluids, tissues and cells. However, owing to the complexity and diversity of the lipidome, lipid research is challenging. Here, the experimental strategies for lipid isolation and characterization will be presented, especially for those who are new to the field of lipid research. Because lipids are known to participate in a host of protein signaling and trafficking pathways, the review emphasizes the understanding of interactions between cellular components, in particular the lipid-protein interrelationships. Novel tools for probing lipid-protein interactions by advanced mass spectrometric techniques will be discussed. It is expected that by integrating the approaches of lipidomics, transcriptomics and proteomics, a clear understanding of the complex functions of lipids will eventually be translated into human diseases. -

Genetic Architecture of Human Plasma Lipidome and Its Link to Cardiovascular Disease
ARTICLE https://doi.org/10.1038/s41467-019-11954-8 OPEN Genetic architecture of human plasma lipidome and its link to cardiovascular disease Rubina Tabassum et al.# Understanding genetic architecture of plasma lipidome could provide better insights into lipid metabolism and its link to cardiovascular diseases (CVDs). Here, we perform genome-wide association analyses of 141 lipid species (n = 2,181 individuals), followed by phenome-wide = 1234567890():,; scans with 25 CVD related phenotypes (n 511,700 individuals). We identify 35 lipid- species-associated loci (P <5 ×10−8), 10 of which associate with CVD risk including five new loci-COL5A1, GLTPD2, SPTLC3, MBOAT7 and GALNT16 (false discovery rate<0.05). We identify loci for lipid species that are shown to predict CVD e.g., SPTLC3 for CER(d18:1/24:1). We show that lipoprotein lipase (LPL) may more efficiently hydrolyze medium length triacylglycerides (TAGs) than others. Polyunsaturated lipids have highest heritability and genetic correlations, suggesting considerable genetic regulation at fatty acids levels. We find low genetic correlations between traditional lipids and lipid species. Our results show that lipidomic profiles capture information beyond traditional lipids and identify genetic variants modifying lipid levels and risk of CVD.

Lipidomics of the Brain, Retina, and Biofluids

Translational Psychiatry (2020) 10:391 https://doi.org/10.1038/s41398-020-01080-1 Translational Psychiatry REVIEW ARTICLE Open Access Lipidomics of the brain, retina, and biofluids: from the biological landscape to potential clinical application in schizophrenia Chuanjun Zhuo 1,2, Weihong Hou3,HongjunTian1,2,LinaWang1,2 and Ranli Li1,2 Abstract Schizophrenia is a serious neuropsychiatric disorder, yet a clear pathophysiology has not been identified. To date, neither the objective biomarkers for diagnosis nor specific medications for the treatment of schizophrenia are clinically satisfactory. It is well accepted that lipids are essential to maintain the normal structure and function of neurons in the brain and that abnormalities in neuronal lipids are associated with abnormal neurodevelopment in schizophrenia. However, lipids and lipid-like molecules have been largely unexplored in contrast to proteins and their genes in schizophrenia. Compared with the gene- and protein-centric approaches, lipidomics is a recently emerged and rapidly evolving research field with particular importance for the study of neuropsychiatric disorders such as schizophrenia, in which even subtle aberrant alterations in the lipid composition and concentration of the neurons may disrupt brain functioning. In this review, we aimed to highlight the lipidomics of the brain, retina, and biofluids in both human and animal studies, discuss aberrant lipid alterations in correlation with schizophrenia, and propose future directions from the biological landscape towards potential clinical applications in schizophrenia. Recent studies are in support of the concept that aberrations in some lipid species [e.g. phospholipids, polyunsaturated fatty acids (PUFAs)] lead to structural alterations and, in turn, impairments in the biological function of membrane-bound proteins, the disruption 1234567890():,; 1234567890():,; 1234567890():,; 1234567890():,; of cell signaling molecule accessibility, and the dysfunction of neurotransmitter systems. -
