Abstract
Phosphatidic acid (PA) is a key bioactive glycerophospholipid that is implicated in the regulation of vital cell functions such as cell growth, differentiation, and migration, and is involved in a variety of pathologic processes. However, the molecular mechanisms by which PA exerts its pathophysiological actions are incompletely understood. In the present work, we demonstrate that PA stimulates the migration of the human non-small cell lung cancer (NSCLC) A549 adenocarcinoma cells, as determined by the transwell migration assay. PA induced the rapid phosphorylation of mitogen-activated protein kinases (MAPKs) ERK1-2, p38, and JNK, and the pretreatment of cells with selective inhibitors of these kinases blocked the PA-stimulated migration of cancer cells. In addition, the chemotactic effect of PA was inhibited by preincubating the cells with pertussis toxin (PTX), a Gi protein inhibitor, suggesting the implication of a Gi protein-coupled receptor in this action. Noteworthy, a blockade of LPA receptor 1 (LPA1) with the specific LPA1 antagonist AM966, or with the selective LPA1 inhibitors Ki1645 or VPC32193, abolished PA-stimulated cell migration. Moreover, PA stimulated the phosphorylation of the transcription factor STAT3 downstream of JAK2, and inhibitors of either JAK2 or STAT3 blocked PA-stimulated cell migration. It can be concluded that PA stimulates lung adenocarcinoma cell migration through an interaction with the LPA1 receptor and subsequent activation of the MAPKs ERK1-2, p38, and JNK, and that the JAK2/STAT3 pathway is also important in this process. These findings suggest that targeting PA formation and/or the LPA1 receptor may provide new strategies to reduce malignancy in lung cancer.

Abstract
Prostate cancer (PCa) is one of the most prevalent cancers in men. Androgen receptor signaling plays a major role in this disease, and androgen deprivation therapy is a common therapeutic strategy in recurrent disease. Sphingolipid metabolism plays a central role in cell death, survival, and therapy resistance in cancer. Ceramide kinase (CERK) catalyzes the phosphorylation of ceramide to ceramide 1-phosphate, which regulates various cellular functions including cell growth and migration. Here we show that activated androgen receptor (AR) is a repressor of CERK expression. We undertook a bioinformatics strategy using PCa transcriptomics datasets to ascertain the metabolic alterations associated with AR activity. CERK was among the most prominent negatively correlated genes in our analysis. Interestingly, we demonstrated through various experimental approaches that activated AR reduces the mRNA expression of CERK: (i) expression of CERK is predominant in cell lines with low or negative AR activity; (ii) AR agonist and antagonist repress and induce CERK mRNA expression, respectively; (iii) orchiectomy in wildtype mice or mice with PCa (harboring prostate-specific Pten deletion) results in elevated Cerk mRNA levels in prostate tissue. Mechanistically, we found that AR represses CERK through interaction with its regulatory elements and that the transcriptional repressor EZH2 contributes to this process. In summary, we identify a repressive mode of AR that influences the expression of CERK in PCa.

Abstract
Gene dosage is a key defining factor to understand cancer pathogenesis and progression, which requires the development of experimental models that aid better deconstruction of the disease. Here, we model an aggressive form of prostate cancer and show the unconventional association of LKB1 dosage to prostate tumorigenesis. Whereas loss of Lkb1 alone in the murine prostate epithelium was inconsequential for tumorigenesis, its combination with an oncogenic insult, illustrated by Pten heterozygosity, elicited lethal metastatic prostate cancer. Despite the low frequency of LKB1 deletion in patients, this event was significantly enriched in lung metastasis. Modeling the role of LKB1 in cellular systems revealed that the residual activity retained in a reported kinase-dead form, LKB1K78I, was sufficient to hamper tumor aggressiveness and metastatic dissemination. Our data suggest that prostate cells can function normally with low activity of LKB1, whereas its complete absence influences prostate cancer pathogenesis and dissemination.

Abstract
The bioactive sphingolipid ceramide 1-phosphate (C1P) regulates key physiologic cell functions and is implicated in a number of metabolic alterations and pathological processes. Initial studies using different types of fibroblasts and monocytes/macrophages revealed that C1P was mitogenic and that it promoted cell survival through inhibition of apoptosis. Subsequent studies implicated C1P in inflammatory responses with a specific role as pro-inflammatory agent. Specifically, C1P potently stimulated cytosolic phospholipase A2 (cPLA2) resulting in elevation of arachidonic acid and pro-inflammatory eicosanoid levels. However, increasing experimental evidence suggests that C1P can also exert anti-inflammatory actions in some cell types and tissues. Specifically, it has been demonstrated that C1P inhibits the release of pro-inflammatory cytokines and blocks activation of the pro-inflammatory transcription factor NF-κB in some cell types. Moreover, C1P was shown to increase the release of anti-inflammatory interleukin-10 in macrophages, and to overcome airway inflammation and reduce lung emphysema in vivo. Noteworthy, C1P stimulated cell migration, an action that is associated with diverse physiological cell functions, as well as with inflammatory responses and tumor dissemination. More recently, ceramide kinase (CerK), the enzyme that produces C1P in mammalian cells, has been shown to be upregulated during differentiation of pre-adipocytes into mature adipocytes, and that exogenous C1P, acting through a putative Gi protein-coupled receptor, negatively regulates adipogenesis. Although the latter actions seem to be contradictory, it is plausible that exogenous C1P may balance the adipogenic effects of intracellularly generated (CerK-derived) C1P in adipose tissue. The present review highlights novel signaling aspects of C1P and its impact in the regulation of cell growth and survival, inflammation and tumor dissemination.

Abstract
The PPARγ coactivator 1 alpha (PGC1α) is a prostate tumor suppressor that controls the balance between anabolism and catabolism. PGC1A downregulation in prostate cancer is causally associated with the development of metastasis. Here we show that the transcriptional complex formed by PGC1α and estrogen-related receptor 1 alpha (ERRα) controls the aggressive properties of prostate cancer cells. PGC1α expression significantly decreased migration and invasion of various prostate cancer cell lines. This phenotype was consistent with remarkable cytoskeletal remodeling and inhibition of integrin alpha 1 and beta 4 expression, both in vitro and in vivo. CRISPR/Cas9-based deletion of ERRα suppressed PGC1α regulation of cytoskeletal organization and invasiveness. Mechanistically, PGC1α expression decreased MYC levels and activity prior to inhibition of invasiveness. In addition, PGC1α and ERRα associated at the MYC promoter, supporting the inhibitory activity PGC1α. The inverse correlation between PGC1α-ERRα activity and MYC levels was corroborated in multiple prostate cancer datasets. Altogether, these results support that PGC1α-ERRα functions as a tumor-suppressive transcriptional complex through the regulation of metabolic and signaling events. SIGNIFICANCE: These findings describe how downregulation of the prostate tumor suppressor PGC1 drives invasiveness and migration of prostate cancer cells.

Abstract
With the advent of OMICs technologies, both individual research groups and consortia have spear-headed the characterization of human samples of multiple pathophysiologic origins, resulting in thousands of archived genomes and transcriptomes. Although a variety of web tools are now available to extract information from OMICs data, their utility has been limited by the capacity of nonbioinformatician researchers to exploit the information. To address this problem, we have developed CANCERTOOL, a web-based interface that aims to overcome the major limitations of public transcriptomics dataset analysis for highly prevalent types of cancer (breast, prostate, lung, and colorectal). CANCERTOOL provides rapid and comprehensive visualization of gene expression data for the gene(s) of interest in well-annotated cancer datasets. This visualization is accompanied by generation of reports customized to the interest of the researcher (e.g., editable figures, detailed statistical analyses, and access to raw data for reanalysis). It also carries out gene-to-gene correlations in multiple datasets at the same time or using preset patient groups. Finally, this new tool solves the time-consuming task of performing functional enrichment analysis with gene sets of interest using up to 11 different databases at the same time. Collectively, CANCERTOOL represents a simple and freely accessible interface to interrogate well-annotated datasets and obtain publishable representations that can contribute to refinement and guidance of cancer-related investigations at all levels of hypotheses and design.Significance: In order to facilitate access of research groups without bioinformatics support to public transcriptomics data, we have developed a free online tool with an easy-to-use interface that allows researchers to obtain quality information in a readily publishable format.

Abstract
Ceramide 1-phosphate (C1P) is a pleiotropic bioactive sphingolipid metabolite capable of regulating key physiologic cell functions and promoting pathologic processes. Concerning pathology, C1P or ceramide kinase (CerK), the enzyme responsible for its biosynthesis in mammalian cells, has been implicated in cancer cell growth, survival, and dissemination and is involved in inflammatory responses associated with different types of cancer cells. The mechanisms or signaling pathways mediating these C1P actions have only been partially described. This chapter reviews recent progress in identifying signal transduction pathways involved in the promotion of cancer cell growth, survival, and dissemination by CerK and C1P.

Abstract
Sphingolipids are not only crucial for membrane architecture but act as critical regulators of cell functions. The bioactive sphingolipid ceramide 1-phosphate (C1P), generated by the action of ceramide kinase, has been reported to stimulate cell proliferation, cell migration and to regulate inflammatory responses via activation of different signaling pathways. We have previously shown that skeletal muscle is a tissue target for C1P since the phosphosphingolipid plays a positive role in myoblast proliferation implying a role in muscle regeneration. Skeletal muscle displays strong capacity of regeneration thanks to the presence of quiescent adult stem cells called satellite cells that upon trauma enter into the cell cycle and start proliferating. However, at present, the exact molecular mechanism by which C1P triggers its mitogenic effect in myoblasts is lacking. Here, we report for the first time that C1P stimulates C2C12 myoblast proliferation via lysophosphatidic acid (LPA) signaling axis. Indeed, C1P subsequently to phospholipase A2 activation leads to LPA1 and LPA3 engagement, which in turn drive Akt (protein kinase B) and ERK1/2 (extracellular signal-regulated kinases 1/2) activation, thus stimulating DNA synthesis. The present findings shed new light on the key role of bioactive sphingolipids in skeletal muscle and provide further support to the notion that these pleiotropic molecules might be useful therapeutic targets for skeletal muscle regeneration.

Abstract
The bioactive sphingolipid ceramide 1-phosphate (C1P) regulates cell division in a variety of cell types including macrophages. However, the mechanisms involved in this action are not completely understood. In the present work we show that C1P stimulates the release of vascular endothelial growth factor (VEGF) in RAW264.7 macrophages, and that this growth factor is essential for stimulation of cell proliferation by C1P. The stimulation of VEGF release was dependent upon activation of the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (PKB-1 also known as Akt-1), and mitogen-activated protein kinase-kinase (MEK)/extracellularly regulated kinase-2 (ERK-2) pathways, as inhibition of these kinases with selective pharmacological inhibitors or with specific gene silencing siRNA, abrogated VEGF release. A key observation was that sequestration of VEGF with a neutralizing antibody, or treatment with VEGF siRNA abolished C1P-stimulated macrophage growth. Also, inhibition of the pathways involved in C1P-stimulated VEGF release inhibited the stimulation of macrophage growth by C1P. Moreover, blockade of VEGF receptor-2 (VEGFR-2), which is the primary receptor for VEGF, with the pharmacological inhibitor DMH4, or with specific VEGFR-2 siRNA, substantially inhibited C1P-stimulated cell growth. It can be concluded that stimulation of VEGF release is a key factor in the promotion of macrophage proliferation by C1P.

Abstract
Prostate cancer is diagnosed late in life, when co-morbidities are frequent. Among them, hypertension, hypercholesterolemia, diabetes or metabolic syndrome exhibit an elevated incidence. In turn, prostate cancer patients frequently undergo chronic pharmacological treatments that could alter disease initiation, progression and therapy response. Here we show that treatment with anti-cholesterolemic drugs, statins, at doses achieved in patients, enhance the pro-tumorigenic activity of obesogenic diets. In addition, the use of a mouse model of prostate cancer and human prostate cancer xenografts revealed that in vivo simvastatin administration alone increases prostate cancer aggressiveness. In vitro cell line systems supported the notion that this phenomenon occurs, at least in part, through the direct action on cancer cells of low doses of statins, in range of what is observed in human plasma. In sum, our results reveal a prostate cancer experimental system where statins exhibit an undesirable effect, and warrant further research to address the relevance and implications of this observation in human prostate cancer.

Abstract
Inflammation is a network of complex processes involving a variety of metabolic and signaling pathways aiming at healing and repairing damage tissue, or fighting infection. However, inflammation can be detrimental when it becomes out of control. Inflammatory mediators involve cytokines, bioactive lipids and lipid-derived metabolites. In particular, the simple sphingolipids ceramides, sphingosine 1-phosphate, and ceramide 1-phosphate have been widely implicated in inflammation. However, although ceramide 1-phosphate was first described as pro-inflammatory, recent studies show that it has anti-inflammatory properties when produced in specific cell types or tissues. The biological functions of ceramides and sphingosine 1-phosphate have been extensively studied. These sphingolipids have opposing effects with ceramides being potent inducers of cell cycle arrest and apoptosis, and sphingosine 1-phosphate promoting cell growth and survival. However, the biological actions of ceramide 1-phosphate have only been partially described. Ceramide 1-phosphate is mitogenic and anti-apoptotic, and more recently, it has been demonstrated to be key regulator of cell migration. Both sphingosine 1-phosphate and ceramide 1-phosphate are also implicated in tumor growth and dissemination. The present review highlights new aspects on the control of inflammation and cell migration by simple sphingolipids, with special emphasis to the role played by ceramide 1-phosphate in controlling these actions.

Abstract
BACKGROUND & AIMS Phosphatidylethanolamine N-methyltransferase (PEMT), a liver enriched enzyme, is responsible for approximately one third of hepatic phosphatidylcholine biosynthesis. When fed a high-fat diet (HFD), Pemt(-/-) mice are protected from HF-induced obesity; however, they develop steatohepatitis. The vagus nerve relays signals between liver and brain that regulate peripheral adiposity and pancreas function. Here we explore a possible role of the hepatic branch of the vagus nerve in the development of diet induced obesity and steatohepatitis in Pemt(-/-) mice. METHODS 8-week old Pemt(-/-) and Pemt(+/+) mice were subjected to hepatic vagotomy (HV) or capsaicin treatment, which selectively disrupts afferent nerves, and were compared to sham-operated or vehicle-treatment, respectively. After surgery, mice were fed a HFD for 10 weeks. RESULTS HV abolished the protection against the HFD-induced obesity and glucose intolerance in Pemt(-/-) mice. HV normalized phospholipid content and prevented steatohepatitis in Pemt(-/-) mice. Moreover, HV increased the hepatic anti-inflammatory cytokine interleukin-10, reduced chemokine monocyte chemotactic protein-1 and the ER stress marker C/EBP homologous protein. Furthermore, HV normalized the expression of mitochondrial electron transport chain proteins and of proteins involved in fatty acid synthesis, acetyl-CoA carboxylase and fatty acid synthase in Pemt(-/-) mice. However, disruption of the hepatic afferent vagus nerve by capsaicin failed to reverse either the protection against the HFD-induced obesity or the development of HF-induced steatohepatitis in Pemt(-/-) mice. CONCLUSIONS Neuronal signals via the hepatic vagus nerve contribute to the development of steatohepatitis and protection against obesity in HFD fed Pemt(-/-) mice.

Abstract
The bioactive sphingolipid ceramide 1-phosphate (C1P) is implicated in inflammatory responses and was recently shown to promote cell migration. However, the mechanisms involved in these actions are poorly described. Using J774A.1 macrophages, we have now discovered a new biological activity of C1P: stimulation of monocyte chemoattractant protein-1 (MCP-1) release. This novel effect of C1P was pertussis toxin (PTX) sensitive, suggesting the intervention of Gi protein-coupled receptors. Treatment of the macrophages with C1P caused activation of the phosphatidylinositol 3-kinase (PI3K)/Akt, mitogen-activated protein kinase kinase (MEK)/extracellularly regulated kinases (ERK), and p38 pathways. Inhibition of these kinases using selective inhibitors or specific siRNA blocked the stimulation of MCP-1 release by C1P. C1P stimulated nuclear factor-κB activity, and blockade of this transcription factor also resulted in complete inhibition of MCP-1 release. Also, C1P stimulated MCP-1 release and cell migration in human THP-1 monocytes and 3T3-L1 preadipocytes. A key observation was that sequestration of MCP-1 with a neutralizing antibody or treatment with MCP-1 siRNA abolished C1P-stimulated cell migration. Also, inhibition of the pathways involved in C1P-stimulated MCP-1 release completely blocked the stimulation of cell migration by C1P. It can be concluded that C1P promotes MCP-1 release in different cell types and that this chemokine is a major mediator of C1P-stimulated cell migration. The PI3K/Akt, MEK/ERK, and p38 pathways are important downstream effectors in this action.

Abstract
It is well established that ceramide 1-phosphate (C1P) is mitogenic and antiapoptotic, and that it is implicated in the regulation of macrophage migration. These activities require high energy levels to be available in cells. Macrophages obtain most of their energy from glucose. In this work, we demonstrate that C1P enhances glucose uptake in RAW264.7 macrophages. The major glucose transporter involved in this action was found to be GLUT 3, as determined by measuring its translocation from the cytosol to the plasma membrane. C1P-stimulated glucose uptake was blocked by selective inhibitors of phosphatidylinositol 3-kinase (PI3K) or Akt, also known as protein kinase B (PKB), and by specific siRNAs to silence the genes encoding for these kinases. C1P-stimulated glucose uptake was also inhibited by pertussis toxin (PTX) and by the siRNA that inhibited GLUT 3 expression. C1P increased the affinity of the glucose transporter for its substrate, and enhanced glucose metabolism to produce ATP. The latter action was also inhibited by PI3K- and Akt-selective inhibitors, PTX, or by specific siRNAs to inhibit GLUT 3 expression.

Abstract
We found that natural (long-chain) ceramide 1-phosphate can be dispersed into aqueous solution when dissolved in an appropriate mixture of methanol/dodecane (49:1, v/v). This solvent mixture facilitates the interaction of this phosphosphingolipid with cells. Under these conditions, incubation of EGFR T17 fibroblasts with natural ceramide 1-phosphate caused a potent stimulation of DNA synthesis. This effect was accompanied by an increase in the levels of proliferating-cell nuclear antigen. Concentrations of natural ceramide 1-phosphate that stimulated the synthesis of DNA did not inhibit adenylate cyclase activity, nor did they stimulate phospholipase D. Natural ceramide 1-phosphate did not alter the cellular phosphorylation state of tyrosine residues or of mitogen-activated protein kinase. Furthermore, natural ceramide 1-phosphate failed to induce the expression of the proto-oncogenes c-myc and c-fos. Both the stimulation of DNA synthesis and the induction of proliferating-cell nuclear antigen by natural ceramide 1-phosphate were inhibited by natural ceramides. This work suggests that the use of methanol and dodecane to deliver natural ceramide 1-phosphate to cells may be useful for elucidation of the biological function(s) and mechanism(s) of action of ceramide 1-phosphate.

Abstract
Concentrations of the bioactive lipids, phosphatidate and diacylglycerol, increased with time in culture in ras- and tyrosine kinase (fps)-transformed fibroblasts but not in control fibroblasts. On Day 3, diacylglycerol and phosphatidate concentrations were about 3.3- and 5.5-fold higher respectively in the ras-transformed compared to control fibroblasts. These concentrations in fps-transformed fibroblasts were increased about twofold. The changes in phosphatidate and diacylglycerol resulted from enhanced phospholipid turnover rather than from synthesis de novo. The increased ratio of phosphatidate to diacylglycerol is explained by decreased activities of two distinct phosphatidate phosphohydrolases and increased diacylglycerol kinase in ras-transformed fibroblasts. Ceramide concentrations were about 2.5- and threefold higher in the fps- and ras-transformed cells respectively on Day 3 compared to the controls. Incubating control fibroblasts from Days 1 to 3 with phosphatidylcholine-specific phospholipase C increased diacylglycerol, phosphatidate and ceramide concentrations, and decreased Mg2+-independent-phosphatidate phosphohydrolase activity. 8-(4-chlorophenylthio)-cAMP had a cytostatic effect in ras-transformed cells, it decreased the concentrations of phosphatidate and diacylglycerol, but increased that of ceramide. The consequences of increased ceramide and phosphatidate concentrations in ras-transformed cells are discussed in relation to signal transduction, cell division and the transformed phenotype.

Abstract
We studied whether TSH or phorbol myristate acetate (PMA) stimulates the hydrolysis of phospholipids, predominantly phosphatidylcholine, via phospholipase D (PLD) in FRTL-5 thyroid cells and whether this occurs as a consequence of protein kinase C (PKC) activation. FRTL-5 thyroid cells were labeled with [3H]myristate followed by incubation with 200 mM ethanol before the addition of agonist. PLD activity was assessed by the measurement of [3H]phosphatidylethanol from [3H]phospholipid (predominantly [3H]phosphatidylcholine). Compared to control values, bovine TSH (100 microU/ml) increased PLD activity by 480% and 600%, respectively, after 30 and 60 min of exposure. Studies with purified human and bovine TSH revealed similar results, indicating that this effect was due to TSH itself. PMA (100 nM) increased PLD activity at 10 min (630% of the control value), and this effect persisted up to 60 min (600% of the control value). To determine whether the effects of TSH on PLD occurred as a consequence of PKC activation, FRTL-5 thyroid cells were preincubated with the PKC inhibitor, chelerythrine (1 microM for 10 min), or were pretreated for 24 h with PMA (100 nM) to down-regulate PKC. PLD stimulation by TSH and PMA was largely abolished by such treatments. These studies indicate that in FRTL-5 thyroid cells, TSH and PMA are capable of stimulating PLD, and that PKC activation is responsible for this stimulation. The role of PLD activation could be to amplify and prolong the PKC signal by further production of diacylglycerol.

Abstract
Ceramide and ceramide-1-phosphate are sphingolipid analogues of diacylglycerol and phosphatidate, respectively, and they are putative second messengers of agonist-stimulated sphingomyelin metabolism. The interactions of exogenous cell-permeable ceramides and ceramide-1-phosphates in modifying DNA synthesis and signal transduction were investigated in Rat-1 fibroblasts. C2- and C8-Ceramide-1-phosphates (N-acetylsphingosine-1-phosphate and N-octanoylsphingosine-1-phosphate, respectively) at 1-10 microM stimulated DNA synthesis and cell division. This effect was blocked by cell-permeable ceramides. C2-Ceramide stimulated the conversion of exogenous C8-ceramide-1-phosphate to C8-ceramide, with very little production of sphingosine or sphingosine-1-phosphate. This mechanism may be partly responsible for preventing the stimulation of DNA synthesis. Unlike phosphatidate or lyso-phosphatidate, concentrations of C8-ceramide-1-phosphate that stimulated DNA synthesis did not inhibit adenylate cyclase activity, nor did they increase the activities of phospholipase D or mitogen-activated protein kinases (42- and 44 kDa isoforms). Although ceramide-1-phosphate can be considered as an analogue of phosphatidate, the effects of this compound on signal transduction differ considerably from those of phosphatidate. This work demonstrates that short-chain ceramide-1-phosphates can be used as novel external agonists that can stimulate DNA synthesis. This effect can be counteracted by short-chain ceramides.

Abstract
The interactions of ceramides with phosphatidate and lysophosphatidate in the regulation of signal transduction in rat fibroblasts were examined. C2- and C6-ceramides (N-acetylsphingosine and N-hexanoylsphingosine, respectively) at 10 microM inhibited the stimulation of DNA synthesis that was produced by 50-100 microM phosphatidate, or lysophosphatidate, or by exogenous phospholipase D. Sphingosine (10 microM) had the opposite effect to the ceramides on DNA synthesis. C2- or C6-ceramides failed to inhibit the stimulation of DNA synthesis by insulin or serum. The ceramides did not modify the actions of phosphatidate, or lysophosphatidate, in decreasing the forskolin-induced increase in cAMP. C2- and C6-ceramides inhibited the stimulation of phospholipase D activity by: (a) phosphatidate, lysophosphatidate, phorbol ester, thrombin, or serum in intact fibroblasts and (b) phorbol ester or guanosine 5'-3-O-(thio)triphosphate in permeabilized fibroblasts. The ceramides can therefore modify cell signaling via phospholipase D, but this effect alone could not explain the decreased DNA synthesis. Incubation of fibroblasts with C2- or C6-ceramides or sphingomyelinase inhibited the interaction of exogenous phosphatidate or lysophosphatidate with the fibroblasts by 42 and 53%, respectively. Furthermore, a greater proportion of the phosphatidate, or lysophosphatidate, that was associated with the fibroblasts was metabolized further when the cells were pretreated with ceramides or sphingomyelinase. This effect was accompanied by an increased activity of N-ethylmaleimide-insensitive phosphatidate phosphohydrolase. Ceramides may therefore produce part of their growth inhibitory effects by blocking some of the signal transducing effects of phosphatidate and lysophosphatidate.

Abstract
The activity of N-ethylmaleimide-insensitive phosphatidate phosphohydrolase (PAP-2) was characterized in control, ras-transformed, and tyrosine kinase-(fps) transformed rat fibroblasts. PAP-2 was assayed in two different ways: 1) within its natural membrane using liposomes of phosphatidate and 2) in the presence of sufficient Triton X-100 to solubilize PAP-2, and to form mixed micelles with the phosphatidate. Harvesting the fibroblasts in medium containing orthovanadate and Zn2+ gave up to 3-fold higher PAP-2 activities when measured in the absence, but not in the presence, of Triton X-100. PAP-2-specific activities from both assays increased in the control fibroblasts as the cells reached confluence. Both specific activities were lower in the oncogenically transformed fibroblasts than in controls at all cell densities tested. The specific activities of PAP-2 did not increase with time in culture in transformed cells which continued to divide. The relative increase in activity of phospholipase D after stimulation with serum or phorbol myristate acetate was lower in the transformed fibroblasts compared to control cells. This indicates a coordinated decrease in the phospholipase D/phosphatidate phosphohydrolase pathway at the level of both enzymes in ras and fps transformed fibroblasts. The ratio of the production of diacylglycerol relative to phosphatidate, after stimulation with serum, or phorbol ester, was lower in both transformed fibroblasts relative to the controls. This is compatible with the decreased specific activity of PAP-2 and indicates functional significance for the differences in PAP-2 activity in regulating the balance between the two mitogenic lipids, phosphatidate and diacylglycerol. Control of PAP-2 activity could be an important factor in regulating appropriate signals for cell division.

Abstract
(1) Feeding increased cholesterol to hamsters resulted in a dose-dependent increase in cholesterol and triacylglycerol in very-low-density lipoprotein (VLDL), in serum non-esterified fatty acids and in the activity of the Mg(2+)-dependent phosphatidate phosphohydrolase in liver. (2) The effects of increasing dietary cholesterol by 0.12% (w/w) in addition to feeding fat (14%, w/w) were dependent upon the nature of the fat. Lard in the presence of 0.12% (w/w) cholesterol increased serum triacylglycerols as did olive oil. By contrast, sunflower oil did not cause a significant change in serum triacylglycerol concentrations. (3) There was a highly positive correlation between VLDL triacylglycerol and VLDL cholesterol concentrations suggesting that, at least in this model, there is a close relationship between hypertriglyceridaemia and hypercholesterolaemia.

Abstract
The activities of two distinct phosphatidate phosphohydrolases (PAP) were measured in livers, hearts and adipose tissues of the JCR:LA corpulent rat which is hyperphagic, hypertriglyceridaemic and insulin resistant. The specific activity of PAP-1, which requires Mg2+, was similar in the livers of lean and corpulent female rats and in male corpulent rats, but these activities were about 1.6-fold higher than in lean males. There was a correlation between the specific activity of PAP-1 and the concentrations of hepatic and serum triacylglycerols in the males, but not in the females. Chronic treatment of the corpulent rats with ethanol did not significantly alter the hepatic activity of PAP-1, or the concentrations of hepatic or serum triacylglycerols. Specific activities of PAP-1 in the heart were higher in the lean compared to the corpulent males. There was no significant difference for the females. Specific activities of PAP-1 were over 5-fold higher in the subcutaneous adipose tissue of the corpulent males and females compared to the lean genotypes. The differences were smaller (1.6-1.9-fold) in the gonadal adipose tissue of both sexes and in the peri-renal depot for the males. PAP-1 activity in the peri-renal depots of corpulent females was 23% lower than in lean females. PAP-2 activity was insensitive to N-ethylmaleimide and did not require Mg2+ for activity. Its activity was 1.5-2.0-fold higher in the livers and hearts of the lean male and female rats than in the corpulent genotypes. Chronic treatment with ethanol increased the activity of PAP-2 in the hearts of the corpulent males, but had no effect in the corpulent females. The specific activity of PAP-2 was higher in subcutaneous, gonadal and peri-renal adipose depots in the females and in the peri-renal depot of the corpulent males compared with the lean genotypes. Lean males had higher specific activities in all three depots compared to lean females. The tissue specificity and the sex differences in the specific activities of PAP-1 and PAP-2 are discussed in terms of their proposed functions in glycerolipid biosynthesis and signal transduction. It is proposed that a decreased activity of PAP-2 could be involved in the insulin insensitivity in the corpulent rats.

Abstract
The activities of two phosphatidate phosphohydrolases were measured in cultured rat hepatocytes incubated with 0.1 mM albumin. The activity, which is inhibited by N-ethylmaleimide (PAP-1) is located in the cytosolic and membrane fractions. PAP-1 activity is stimulated by Mg2+ and it can be translocated from the cytosol to the membranes by relatively low (0.5-1 mM) concentrations of fatty acids. In addition, higher concentrations (1-3 mM) of fatty acids cause an increase in the total PAP-1 activity. Translocation of PAP-1 activity in the hepatocytes is preferentially promoted by unsaturated fatty acids (C18:1, C18:2, C18:3, C20:4 and C20:5), rather than by saturated acids (C14:0, C16:0, C18:0). Increasing the extracellular concentration of albumin from 30 microM to 1 mM displaces PAP-1 activity from the membrane fraction. Sphingosine, but not staurosporine, can inhibit the redistribution of PAP-1 activity induced by oleate. The amphiphilic amines, sphingosine, chlorpromazine and propranolol, also decrease membrane-bound PAP-1 activity in the absence of fatty acids, but they do not alter, significantly, the activity of the cytosolic PAP-1. In the presence of 1 mM oleate, sphingosine, chlorpromazine and propranolol decrease the translocation of PAP-1 from the cytosol to the membranes. The phosphohydrolase activity, which is insensitive to N-ethylmaleimide (PAP-2), is specifically located in the plasma membrane (Jamal, Z., Martin, A., Gomez-Muñoz, A. and Brindley, D.N. (1991) J. Biol. Chem. 266, 2988-2996) and it is not stimulated by Mg2+. Saturated fatty acids, albumin, sphingosine and propranolol have no significant effects on PAP-2 activity. However, chlorpromazine decreases PAP-2 activity by about 14%. Linolenate, arachidonate and eicosapentaenoate at 1 mM also produced small (7-10%) decreases in PAP-2 activity. It is proposed that both PAP-1 and PAP-2 activities may be involved in signal transduction, although the main function of PAP-1 seems to be involved in the synthesis of glycerolipids.

Abstract
Incubation of hepatocytes with okadaic acid displaced the N-ethylmaleimide-sensitive phosphatidate phosphohydrolase from the membrane fraction into the cytosol and partially prevented the oleate-induced movement of phosphohydrolase from cytosol to membranes. However, higher concentrations of oleate still caused translocation and activation of the phosphohydrolase. This enzyme is stimulated by Mg2+, and is probably involved in glycerolipid synthesis. Okadaic acid also decreased the concentration of diacylglycerol within the hepatocytes. Okadiac acid had no observable effect on the activity of an N-ethylmaleimide-insensitive phosphatidate phosphohydrolase which remained firmly attached to membranes. This activity is not stimulated by Mg2+ and is probably involved in signal transduction by the phospholipase D pathway.

Abstract
Oleate, linoleate, linolenate, arachidonate and eicosapentaenoate, but not myristate, palmitate and stearate, stimulated glycogen phosphorylase activity by 2-8-fold when added to cultured rat hepatocytes. Addition of BSA or Ca2- to the incubation medium decreased the stimulating effects of the unsaturated fatty acids. The combination of oleate or linolenate, with corticosterone, testosterone or estradiol produced synergistic stimulations of phosphorylase activity. The stimulation of glycogen phosphorylase activity by linolenate was inhibited by staurosporine or sphingosine. Staurosporine (80 nM) alone also decreased basal phosphorylase activities by about 60%. The results show that unsaturated fatty acids can be used as model agonists to stimulate phosphorylase activity by a mechanism that probably involves protein kinase C. On the basis of the fatty acid: BSA ratios used, this stimulation should only occur in vivo at high fatty acid concentrations when accompanied by hypoalbuminaemia.

Abstract
Assays for two distinct phosphatidate phosphohydrolase activities were established based upon a differential inhibition by N-ethylmaleimide (NEM). The activity that is insensitive to this reagent in rat liver is predominantly in the plasma membrane fraction, whereas the NEM-sensitive activity is in the cytosolic and microsomal fractions. The NEM-insensitive activity is further distinguished from the NEM-sensitive phosphohydrolase by: (a) being relatively stable to heat; (b) not being inhibited by phenylglyoxal, butane-2,3-dione, cyclohexane-1,2-dione, 2,4-dinitrofluorobenzene, 7-chloro-4-nitrobenz-2-oxa-1,3-diazole, and diethyl pyrocarbonate; (c) being inhibited by NaF and phosphatidylcholine; and (d) not being stimulated by Mg2+. The NEM-insensitive activity was specific for phosphatidate. Both phosphohydrolase activities could be inhibited by chlorpromazine, propranolol, sphingosine, and spermine. The NEM-sensitive phosphatidate phosphohydrolase activity was increased by incubating hepatocytes for 12 h with glucagon and dexamethasone, and this effect was antagonized by insulin. The NEM-sensitive phosphohydrolase is concluded to be involved in glycerolipid synthesis. The activity of the NEM-insensitive phosphohydrolase was not altered by preincubation of rat hepatocytes in the short or long term with vasopressin, glucagon, insulin, triiodothyronine, or dexamethasone, but it might be modulated indirectly by sphingosine. The NEM-insensitive enzyme of the plasma membranes could be involved in signal transduction via the agonist-stimulated degradation of phosphatidylcholine through the phospholipase D pathway.

Abstract
Testosterone (40-300 microM), oestradiol (20-500 microM), progesterone (20-500 microM), dexamethasone (10 nM-1 microM) and corticosterone (1-10 microM) activate glycogen phosphorylase rapidly when added directly to hepatocytes. The activation of phosphorylase was concentration-dependent and occurred after 10 min for dexamethasone, 30 min for testosterone and 60 min for oestradiol and progesterone. This rapid effect does not appear to be dependent on a stimulation of protein synthesis, it is independent of an increase in cyclic AMP, and it is not diminished by the presence of ornithine decarboxylase inhibitors. The stimulation of phosphorylase activity is diminished by depleting the incubation medium of Ca2+ in the presence of 0.5 mM-EGTA, and therefore it may involve changes in the distribution of Ca2+ in the hepatocytes. These results may explain some of the pharmacological effects of sex steroids, and also might contribute to the physiological actions of glucocorticoids.

Abstract
Glycogen phosphorylase activity is increased before protein synthesis activation by progesterone. This effect is not blocked by antibiotics (actinomycin D and cycloheximide) that are known to inhibit mRNA or protein synthesis. At times similar to those of phosphorylase activation, cAMP are not enhanced, as would be expected considering the classical glycogenolytic cascade, but depleted with respect to control values. A little earlier, cGMP levels are significantly increased.

Abstract
The content of hepatic phospholipids, cholesterol and triglycerides was studied in 14, 17 and 20 day old chick embryos and newborn chicks (21 incubation days). An increase in the total lipid content and in the other lipidic fractions throughout embryo development is observed, mainly between 17 and 20 days of incubation, remaining practically constant until the hatchability day. Nevertheless a sharp depletion of triglycerides in broken eggshell day is revealed. Effect of a single dose of 3-3'-5-Triiodothyronine (T3) on hepatic lipid levels was determined. Throughout embryonary period, the hormone only affects triglyceride levels enhancing its biosynthesis in the 20th incubation day. All the other variations are described in newborn animals.
