Various phospholipases are thought to be associated with the in vitro apoptosis of thymocytes. In the present study, the in vivo phospholipase D (PLD) activity of rat thymus was studied after whole-body X-irradiation or injection of dexamethasone (DEX). Using exogenous [14C]dipalmitoyl
Drosophila melanogaster phototransduction proceeds via a phospholipase C (PLC)-triggered cascade of phosphatidylinositol (PI) lipid modifications, many steps of which remain undefined. We describe the involvement of the lipid phosphatidic acid and the enzyme that generates it, phospholipase D (Pld),
Phospholipase D (PLD, EC 3.1.4.4) is a key enzyme involved in phospholipid catabolism, initiating a lipolytic cascade in membrane deterioration during senescence and stress, which was cloned from Jatropha curcas L., an important plant species as its seed is the raw material for biodiesels. The cDNA
mTOR is a major actor of skeletal muscle mass regulation in situations of atrophy or hypertrophy. It is established that Phospholipase D (PLD) activates mTOR signaling, through the binding of its product phosphatidic acid (PA) to mTOR protein. An influence of PLD on muscle cell size could thus be
Phospholipase D (PLD) is implicated in important cellular processes such as signal transduction, membrane trafficking, and mitosis regulation. Recently, cDNA for human PLD1 (hPLD1) was cloned from HeLa cells (Hammond, S. M., Altshuller, Y. M., Sung, T-C., Rudge, S. A., Rose, K., Engebrecht, J.,
Seed aging decreases the quality of seed and grain and results in agricultural and economic losses. Alterations that impair cellular structures and metabolism are implicated in seed deterioration, but the molecular and biochemical bases for seed aging are not well understood. Ablation of the gene
Phospholipase D (PLD, EC 3.1.4.4) has been known to be related to various cellular processes in plants. To gain an understanding of the property of the enzyme in Pimpinella brachycarpa, the cDNA of the enzyme was isolated by PCR with degenerate primers, cDNA library screening, and 5' RACE. The
Membrane disruption has been proposed to be a key event in plant senescence, and phospholipase D (PLD; EC 3.1.4.4) has been thought to play an important role in membrane deterioration. We recently cloned and biochemically characterized three different PLDs from Arabidopsis. In this study, we
Phospholipase D (PLD; EC 3.1.4.4) has been proposed to be involved in a number of cellular processes including transmembrane signaling and membrane deterioration. PLD previously described from various plant sources generally requires millimolar ranges of calcium for optimal activity. In this study,
Our previous finding, that the capsaicin- and KCl-induced Ca(2+)-dependent production of the intra- and intercellular signaling molecule N-arachidonoyl ethanolamine (anandamide) in cultured primary sensory neurons could be abolished and reduced by approximately 2/3 by capsaicin-induced degeneration
We have previously obtained three partial rat phospholipase D (PLD) cDNA fragments by a reverse transcriptase-polymerase chain reaction (RT-PCR) method using degenerate primers based on two conserved amino acid sequences in PLDs of human and yeast. The entire coding regions of these genes were
GTP gamma S-dependent phospholipase D (PLD) activity time-dependently increased during differentiation of rat C6 glioma cells to astrocytic phenotypes induced by dibutyryl cyclic AMP (dbcAMP)/theophylline. The changes in PLD mRNA level were examined by reverse transcriptase-polymerase chain reaction
Phosphatidylcholine-specific phospholipase D (PLD) hydrolyzes the phosphodiester bond of the phosphatidylcholine to generate phosphatidic acid (PA) and regulates several sub-cellular functions. Mammalian genomes contain two genes encoding distinct isoforms of PLD in contrast to invertebrate genomes
Phospholipase D (PLD), which is present in plant, bacterial, and mammalian cells, has been proposed to be involved in a number of cellular processes including transmembrane signaling and membrane deterioration. We demonstrated the existence of evolutionally related PLD activity in the unicellular
Phospholipase D alpha (PLD, EC 3.1.4.4)) is a key enzyme involved in membrane deterioration that occurs during fruit ripening and senescence. The biochemical and molecular characteristics of PLD was studied in strawberry (Fragaria ananassa Duch) fruits, which are non-climacteric fruits. PLD activity
