Regulation of PIEZO Channels by Membrane Lipids
… including but not limited to changes in membrane electric potential, Ca2+ signaling, and gene expression. Among such protein complexes, mechanosensitive ion channels stand out as the quickest mechanotransductors, as they can generate physiologically relevant responses to mechanical cues, …

Membrane Lipids and Synaptic Vesicle Trafficking in the CNS
… that the compositions the synaptic vesicle membranes are somehow unique between pools. The first three chapters explore the role of cholesterol in synaptic transmission. We treated hippocampal cultures with methyl-beta-cyclodextrin, which reversibly binds cholesterol, or mevastatin, an …

Environmental controls on the distribution of bacterial membrane lipids
Since their discovery in ancient sediments, hopanes and their biological precursors, bacteriohopanepolyols (BHPs), have been of great interest for their potential to serve as proxies for bacteria in the geological record. The validation of these and other biomarkers have implications for …

Regulation of cellular functions of PDZ domains by membrane lipids.
… of cellular functions of PDZ domains by membrane lipids.

Exploring the distribution and physiological roles of bacterial membrane lipids in the marine environment
Lipids have a legacy in the geologic record extending back to the Archaean. Since the phylogenetic diversity of life is reflected in the structural diversity of biomolecules, lipid biomarkers that are shown to be diagnostic of certain organisms that carry out specific biochemical processes or that …

Exploration of Platelet and Mast Cell Communication: A Study of Membrane Lipids, Asthma, and Inflammation
… examines how environmental factors such as lipid membrane concentration, opioid agonist exposure, and inflammatory diseases impact cell communication. It explores the use of different cell models, specifically platelets and mast cells, to understand how disease states can impact cellular function. …

Effects of Muscadine Grape Products on Healthy and Type 2 Diabetic Subjects: Blood Chemistry, Antioxidant Capacity and Membrane Lipids
… antioxidant capacity, and erythrocyte membrane lipids of free living T2D and control, non-diabetic subjects. Two Control groups, MJ- group and control without supplementation (CS); and three T2D groups, MJ, DzW and MW each consumed 150 ml of the grape product daily (except for CS) with …

The Effect of Hypercholesterolemia on the Membrane Lipids, 3-0-[¹⁴C] Methylglucose Transport, and 2,3-Diphosphoglycerate Levels in Rat Erythrocytes
… separate experiments on the erythrocytes: a membrane cholesterol and phospholipid determination, a 3-0-[<sup>14</sup>C] methylglucose (30MG) transport determination, and a 2,3-diphosphoglycerate (2,3 DPG) determination. The 30MG transport and 2,3 DPG aliquots were each incubated in the same …

Examining the Roles of Membrane Lipids and Secreted Bioactive Lipids on Immune System Cell Function: Studies on Mast Cells and Platelets
… understanding of the role of both secreted lipids that act as short-range hormones and structural lipids that play an active role in cellular signaling in the function of immune system cells. Lipids, both as the cell-secreted mediators of inflammation and as important structural components …

Understanding the biochemical basis of temperature induced lipid pathway adjustments in plants
… in plants is the adjustment in the degree of membrane unsaturation. Glycerolipids are major constituents of cellular membranes. In higher plants, glycerolipids are synthesized via two major metabolic pathways compartmentalized in the ER and chloroplast. Adaptive responses in membrane lipids …

The Reconstruction of Climate in Beringia by analysis of Glycerol Dialkyl Glycerol Tetraether (GDGT) Distributions using High Performance Liquid Chromatography – Mass Spectrometry (HPLC-MS).
… across both glacial and interglacial timescales. Membrane lipids synthesised by archaea and bacteria are retained within the sediment and when extracted give evidence to the environmental conditions present during the organism’s lifetime. The membrane lipids are structured in a way that is …

Lipid metabolism and mitochondrial respiration in adipose tissue and liver during obesity
… obese mice correlated with lipid remodelling in membranes i.e. phosphatidylcholine/phosphatidylethanolamine (PC/PE) ratios in both brown and white adipose tissues. When the effects of sex and obesity were investigated in adipose tissue, a positive correlation was again detected between PC/PE …

The effects of altered membrane fatty acid composition on the toxic interactions of heavy metals with Saccharomyces Cerevisiae
The effects of altered membrane fatty acid composition on the toxic interactions of heavy metals with Saccharomyces cerevisiae were examined. Saccharomyces cerevisiae was enriched with the polyunsaturated fatty acids (PUFAs) linoleate (18:2) and linolenate (18:3) by growth in 18:2- or …

INTERACTIONS OF ENVIRONMENTAL POLLUTANTS WITH MICROALGAE AND LICHEN: INSIGHTS FROM MULTI-PLATFORM METABOLOMICS
… ion exposure in the metabolism of chlorophylls, membrane lipids, glutathione, and osmolytes. Only fatty acids oxidation was particle-specific. In chapter 4, elemental and metabolic profiles of the lichen Dirinaria picta after exposure to road traffic revealed heavy metal detoxification mechanism …
