Abstract
AIM The data on the beneficial effect of ursodeoxycholic acid (UDCA) in non-alcoholic steatohepatitis (NASH) are controversial. The difference of opinion is connected with UDCA dosage to be used. Therefore, we evaluated the dose-dependent efficacy of UDCA in experimental NASH. METHODS Male Wistar rats were fed the methionine- and choline-deficient (MCD) diet for 10 weeks. Rats were administrated UDCA (10, 20, 40 and 80 mg/kg bodyweight intragastrically) after 6 weeks of the MCD diet. RESULTS Animals fed the MCD diet developed severe steatohepatitis. Treatment with UDCA dose-dependently decreased liver damage, but only high-dose UDCA (80 mg/kg) significantly diminished ultrastructural changes in addition to preventing steatosis, ballooning and inflammatory changes in the liver. The activities of serum marker enzymes and the content of liver triglyceride and blood glucose were increased in MCD diet-fed rats, but decreased in all the UDCA-treated groups. Serum insulin concentration was decreased whereas the quantitative insulin sensitivity check index did not changed in MCD diet-fed groups. Serum tumor necrosis factor-α content was strongly increased after MCD diet and normalized in the UDCA-treated rats, with the most pronounced effect in the highest dose groups, 40 and 80 mg/kg. The contents of endogenous ethanol in blood and intestinal mucus were increased in MCD diet-fed rats which were significantly lowered by UDCA (40 and 80 mg/kg per day). CONCLUSION The present data demonstrate a beneficial effect of UDCA that manifested by the decrease of liver steatosis, inflammatory signs and serum tumor necrosis factor-α content especially of the highest 40 and 80 mg/kg day doses.

Abstract
An intermediate in the fatty acid biosynthetic pathway, malonyl-coenzyme A (CoA), has emerged as a major regulator of energy homeostasis not only in peripheral metabolic tissues but also in regions of the central nervous system that control satiety and energy expenditure. Fluctuations in hypothalamic malonyl-CoA lead to changes in food intake and peripheral energy expenditure in a manner consistent with an anorexigenic signaling intermediate. Hypothalamic malonyl-CoA is regulated by nutritional and endocrine cues including glucose and leptin, respectively. That malonyl-CoA is an essential component in the energy homeostatic signaling system of the hypothalamus is supported by convergence of physiological, pharmacological, and genetic evidence. This review will focus on evidence implicating malonyl-CoA as a central player in the control of body weight and adiposity as well as clues to the molecular mechanism by which carbon flux through the fatty acid biosynthetic pathway is linked to the neural control of energy balance.

Abstract
The Kupffer-cell products interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-alpha) have been shown to stimulate hepatic lipogenesis in vivo. Studies were performed to define the direct effects of these cytokines on lipogenesis in primary-culture rat hepatocytes. Hepatocytes were cultured in the presence of IL-6 or TNF-alpha for periods of 24-72 h. IL-6 increased hepatocyte protein content per microgram of DNA. IL-6 also caused a dose- and time-dependent induction of hepatocyte capacity for incorporation of [2-14C]pyruvate into fatty acids (56% increase by 12.5 ng/ml IL-6 after 72 h of cytokine exposure). This increase in cellular lipogenic capacity was confirmed by using 3H2O incorporation into fatty acids as tracer. TNF-alpha did not increase hepatocyte lipogenesis. In contrast with studies in vivo, neither IL-6 nor TNF-alpha had any acute (2 h of exposure) effects on rates of lipogenesis. Both IL-6 and TNF-alpha are known to increase macrophage prostaglandin synthesis acutely. The prostaglandin E agonist misoprostol free acid (0.1 microM) acutely increased hepatocyte lipogenic rates by 14%. Thus, IL-6 can directly induce hepatocyte lipogenic capacity, and E-series prostaglandins can antagonize the acute inhibition of lipogenesis by glucagon. The observations provide further evidence for the role of Kupffer-cell products in the regulation of hepatocyte metabolism.

Abstract
Rat hindlimb muscle tissue was extracted from male Sprague-Dawley rats exsanguinated under light ether anesthesia. Muscle homogenates (50,000 x g supernatant) were incubated with ATP, bicarbonate, acetyl-CoA, and citrate. The quantity of malonyl-CoA synthesized was determined by malonyl-CoA incorporation into long acyl chains using tritiated acetyl-CoA and fatty acid synthetase. Malonyl-CoA synthesis was found to be dependent on the presence of ATP, bicarbonate, citrate, and acetyl-CoA in the incubation medium. Incubation with avidin showed near complete inhibition of carboxylation that was restored with the addition of biotin. These results represent strong evidence of a biotin containing acetyl-CoA carboxylase in skeletal muscle.

Abstract
Acetyl-CoA carboxylase (EC 6.4.1.2) in hepatocytes from meal-fed rats was activated by phorbol myristate acetate (PMA) in a time- and concentration-dependent fashion. This activation can account for the PMA-induced stimulation of de novo fatty acid synthesis. Purified rat-liver acetyl-CoA carboxylase was found to be phosphorylated and activated by protein kinase C, thus providing a possible mechanism for the metabolic action of PMA in intact hepatocytes.

Abstract
Relationships between the cyclic AMP content, the rate of lipogenesis and the activity of acetyl-CoA carboxylase in acini prepared from lactating rat mammary tissue were investigated by exposing them to agents that increase their cyclic AMP content in the presence or absence of insulin. The dose-dependent inhibition of lipogenesis by theophylline in acini isolated from fed rats was highly correlated with the induced increases in acinar cyclic AMP content. Cyclic AMP of acini from 24 h-starved lactating rats was more sensitive in its response to theophylline than that in acini from fed animals. Neither forskolin nor a mixture of isoprenaline and Ro 7-2956 were able significantly to change either the rate of lipogenesis or the activity of acetyl-CoA carboxylase in acini from fed rats when added to incubations in vitro, in spite of the large increases in cyclic AMP concentration produced by these agents. Insulin was without effect on the activity of acetyl-CoA carboxylase and on either the basal or isoprenaline-stimulated cyclic AMP content of acini. These results are discussed in terms of the possibility that the rate of lipogenesis and the cyclic AMP content in mammary acini can vary independently of one another and of the activity of acetyl-CoA carboxylase.

Abstract
During the formation of rape-seeds, lipid accumulated in the cotyledons from 16 days after pollination, rising to a plateau after 28 days. The accumulation of lipid was preceded by a marked rise in acetyl-CoA carboxylase activity, which declined rapidly, correlating with the decline in rate of lipid formation. Incubation of rape-seed extracts with avidin-agarose resulted in a decrease in acetyl-CoA carboxylase activity in the extract. Polyacrylamide-gel electrophoresis of polypeptides bound to avidin-agarose showed the presence of a polypeptide of Mr 225 000. The intensity of this band increased during the period of increase of acetyl-CoA carboxylase activity in the seeds.

Abstract
With some lines of oil-palm tissue cultures embryogenesis occurs spontaneously within the callus grown on a medium containing 2.5 mg of 3-naphthylacetic acid/litre. One of the initial biochemical events that occurs just before the embryoid can be seen is the accumulation of fat droplets within the cells. This accumulation of lipid is correlated with an increase in acetyl-CoA carboxylase activity. The carboxylase is thus probably a rate-limiting step in fatty acid synthesis in these cells and can be used as a quantitative marker of somatic embryogenesis within the tissue. During the development of the embryoid tissue there is an increase in cell division and the differentiation of vascular cells with secondary thickened walls. These stages of the differentiation may be monitored by measuring the ratio of pectin synthesis (polygalacturonic acid formation) to hemicellulose synthesis (xylan formation).

Abstract
The present experiments tested whether acetate plays a role in the provision of acetyl-CoA for acetylcholine synthesis in the cat's superior cervical ganglion. Labeled acetylcholine was identified in extracts of ganglia that had been perfused for 20 min with Krebs solution containing choline (10(-5) M) and [3H], [1-14C], or [2-14C]acetate (10(-3) M); perfusion for 60 min or with [3H]acetate (10(-2) M) increased the labeling. The acetylcholine synthesized from acetate was available for release by a Ca2+-dependent mechanism during subsequent periods of preganglionic nerve stimulation. When ganglia were stimulated via their preganglionic nerves or by exposure to 46 mM K+, the labeling of acetylcholine from [3H]acetate was reduced when compared with resting ganglia. The reduced synthesis of acetylcholine from acetate during stimulation was not due to acetate recapture, shunting of acetate into lipid synthesis, or the transmitter release process itself. In ganglia perfused with [2-14C]glucose, the amount of labeled acetylcholine formed was clearly enhanced during stimulation. An increase in acetylcholine labeling from [3H]acetate was shown during a 15-min resting period following a 60-min period of preganglionic nerve stimulation (20 Hz). It is concluded that acetate is not the main physiological acetyl precursor for acetylcholine synthesis in this sympathetic ganglion, and that during preganglionic nerve stimulation there is enhanced delivery of acetyl-CoA to choline acetyltransferase from a source other than acetate.

Abstract
1. The activity of acetyl-CoA carboxylase (EC 6.4.1.2) in extracts of freeze-clamped liver samples from fed or 24 h-starved virgin, pregnant, lactating and weaned rats was measured (i) immediately after preparation of extracts (;I activity'), (ii) after incubation of extracts with partially purified preparations of either rabbit muscle protein phosphatase 1 [Antoniw, Nimmo, Yeaman & Cohen (1977) Biochem. J.162, 423-433] or rabbit liver phosphatase [Brandt, Capulong & Lee (1975) J. Biol. Chem.250, 8038-8044] (;A activity') and (iii) after incubation with 20mm-potassium citrate before or after incubation with phosphatases (;C activity'). 2. Incubation of liver extracts at 30 degrees C without any additions resulted in activation of acetyl-CoA carboxylase that was shown to be due to dephosphorylation of the enzyme by endogenous protein phosphatase activity. This latter activity was not stimulated by Ca(2+) and/or Mg(2+) but was stimulated by 1 mm-Mn(2+). Incubation of extracts with either of the partially purified phosphatases (0.2-0.5 unit) resulted in faster dephosphorylation and activation. The activity achieved after incubation with either of the exogenously added phosphatases was similar. 3. The A and C activities increased during late pregnancy, were lower than in the virgin rat liver during early lactation and increased by 2-fold in liver of mid-lactating rats. Weaning of mid-lactating rats for 24 h resulted in no change in A and C activities but after 48 h weaning they were significantly lower than those in livers from suckled mothers. 4. The I activity followed a similar pattern of changes as the A and C activities during pregnancy and lactation such that, although the I/A and I/C activity ratios tended to be lower during late pregnancy and early lactation, there were no significant changes in I/A and I/C ratios between lactating and virgin animals. However, these ratios were significantly higher in liver from fed 24 h-weaned animals. 5. Starvation (24 h) resulted in a marked decrease in I activity for all animals studied except early-lactating rats. This was due to a combination of a decrease in the concentration of acetyl-CoA carboxylase in liver of starved animals (A and C activities) and a decrease in the fraction of the enzyme in the active form (lower I/C and I/A ratios). The relative importance of the two forms of regulation in mediating the starvation-induced fall in I activity was about equal in livers of virgin, pregnant and lactating animals. However, the decrease in I/A and I/C ratios was of dominating importance in livers of weaned animals. The A/C activity ratios were the same for livers from all animals studied. 6. The maximal activity of fatty acid synthase was also measured in livers and was highly and positively correlated with the A and C activities of acetyl-CoA carboxylase, suggesting that the concentrations of the two enzymes in the liver were controlled coordinately. 7. It is suggested that the lack of correlation between plasma insulin levels and rates of lipogenesis in the transition from the virgin to the lactating state may be explained by different effects of insulin and prolactin on the concentration of acetyl-CoA carboxylase in the liver and on the fraction of the enzyme in the active form.

Abstract
The ;initial' (I), endogenous phosphatase-activated (A) and citrate-activated (C) activities of acetyl-CoA carboxylase were measured in mammary-gland extracts of pregnant and lactating rats. There was a 10-fold increase in the A and C enzyme activities in the transition from early to peak lactation [cf. data of Mackall & Lane (1977) Biochem. J.162, 635-642], but there was no significant increase in the ratio of the initial activity to the A and C activities of the enzyme. Starvation (24h) or short-term (3h) streptozotocin-induced diabetes both resulted in a 40% decrease in I/A and I/C activity ratios. In starvation this was accompanied by a decrease in the absolute values of the A and C activities such that the initial activity in mammary glands of starved animals was 45% that in glands from fed animals. Insulin treatment of starved or diabetic animals 60min before killing increased the I activity without affecting the A or C enzyme activities. Removal of the pups for 24h from animals in peak lactation (weaning) resulted in a marked but similar decrease in all three activities such that, although the initial activity was only 10% of that in suckled animals, the I/A and I/C activity ratios remained high and unaltered. Inhibition of prolactin secretion by injection of 2-bromo-alpha-ergocryptine gave qualitatively similar results to those during weaning. Simultaneous administration of ovine prolactin completely prevented the effects of bromoergocryptine. It is suggested that the initial activity of acetyl-CoA carboxylase in rat mammary gland is regulated by at least two parallel mechanisms: (i) an acute regulation of the proportion of the enzyme in the active state and (ii) a longer-term modulation of enzyme concentration in the gland. Insulin appeared to mediate its acute effects through mechanism (i), whereas prolactin had longer-term effects on enzyme concentration in the gland. A comparison of initial enzyme activities (I) obtained in the present study with rates of lipogenesis measured in vivo [Agius & Williamson (1980) Biochem. J.192, 361-364; Munday & Williamson (1981) Biochem. J.196, 831-837] gave good agreement between the two sets of data for all conditions studied except for 24h-starved and streptozotocin-diabetic animals. It is suggested that acetyl-CoA carboxylase activity is rate-limiting for lipogenesis in the mammary gland in normal, fed, suckled or weaned animals but that in starved and short-term diabetic animals changes in the activity of the enzyme by covalent modification alone may not be sufficient to maintain the enzyme in its rate-limiting role.
