Controlling lipid accumulation in cereal grains
Plant Science, 2012Plant oils have so far been mostly directed toward food and feed production. Nowadays however, these oils are more and more used as competitive alternatives to mineral hydrocarbon-based products. This increasing demand for vegetable oils has led to a renewed interest in elucidating the metabolism of storage lipids and its regulation in various plant ...

Accumulation of lipids and lipid-intermediates in the heart during ischaemia
1987The content of non-esterified fatty acids (NEFA) and their CoA and carnitine esters is low in normoxic cardiac tissue. The majority of fatty acids is esterified in the triacylglycerol and phosphoglyceride pool. During myocardial ischaemia beta-oxidation of fatty acids is inhibited. In addition, turnover of the esterified fatty acid pools is most likely

Lipid Accumulation Mechanisms in Auto- and Heterotrophic Microalgae
Journal of Agricultural and Food Chemistry, 2017Microalgae lipids have attracted great attention in the world as a result of their potential use for biodiesel productions. Microalgae are cultivated in photoautotrophic conditions in most cases, but several species are able to grow under heterotrophic conditions, in which microalgae are cultivated in the dark where the cell growth and reproduction are

Regulation of lipid accumulation in oleaginous microorganisms
Biochemical Society Transactions, 2002A small number of eukaryotic micro-organisms, the oleaginous species, can accumulate triacylglycerols as cellular storage lipids, sometimes up to 70% of the biomass. Some of these lipids, particularly those containing high proportions of polyunsaturated fatty acids of nutritional and dietary importance, are now in commercial production; these are known

Accumulation of lipid and nonlipid constituents in rabbit atheroma
Journal of Atherosclerosis Research, 1964Summary Six groups of 10 rabbits each were fed 1% cholesterol for periods up to 4 months. Free and esterified cholesterol of the thoracic intima were observed to increase exponentially early in the experiment. The rate of cholesterol accumulation was found to depend on time of exposure to atherogenic diet as well as on serum cholesterol level.

Oxfenicine-induced accumulation of lipid in the rat myocardium
Journal of Molecular and Cellular Cardiology, 1988Oxfenicine inhibits myocardial metabolism of nonesterified fatty acids (NEFA). The purpose of the present study was to examine the effects of oxfenicine on triglyceride accumulation and the development of histologically visible lipid droplets. The beta-agonist isoproterenol was used to induce elevated arterial NEFA. Four groups of rats were used in the

Lipid metabolism and accumulation in perfused rabbit aorta
Journal of Surgical Research, 1979Abstract A model is described for study of lipid accumulation and metabolism in an in situ segment of perfused aorta. This technic was used in 36 normal rabbits to determine the influence of pressure on the uptake and synthesis of vascular lipids.

Methods to Assess Lipid Accumulation in Cancer Cells
2014Oncogenesis and tumor progression are associated with significant alterations in cellular metabolism. One metabolic pathway that is commonly deregulated in malignant cells is de novo lipogenesis. Lipogenesis is indeed highly upregulated in several types of cancer, a phenomenon that is linked to tumor progression and poor prognosis.

Simultaneous growth and neutral lipid accumulation in microalgae
Bioresource Technology, 2013In this paper the hypothesis was tested whether TAG accumulation serves as an energy sink when microalgae are exposed to an energy imbalance caused by nutrient limitation. In our continuous culture system, excess light absorption and growth-limiting nitrogen supply rates were combined, which resulted in accumulation of TAG (from 1.5% to 12.4% w/w) in ...

Lipid Accumulation in the Vessel Wall
1989Since the early 1970s experiments have demonstrated that lesions of the arterial wall, morphologically and chemically resembling those seen in atherosclerosis in man, can be induced by various forms of injury to the inner lining of the vessel [69]. The lesions occur without dietary manipulation of the blood lipid content. These observations have led to
