Effect of vitamin E- and selenium-deficiency on rat liver chemiluminescence.

The role of vitamin E and selenium as protective agents against oxidative stress was evaluated by measuring liver chemiluminescence in situ. Weanling rats fed a vitamin E- and selenium-deficient diet showed liver chemiluminescence that was increased 60 and 100% over control values at 16 and 18 days respectively after weaning. At day 21, the double deficiency led to hepatic necrosis, as observed by optical and electron microscopy, and increased serum levels of lactate dehydrogenase and alanine aminotransferase. Single deficiencies, in either vitamin E or selenium, did not produce liver necrosis but increased liver chemiluminescence. Vitamin E deficiency led to a 23 and 50% increase in liver emission at days 18 and 20 respectively; selenium deficiency produced a 64% increase at day 16. The activity of liver selenium-glutathione peroxidase diminished to 13% of the control value in the rats fed doubly deficient and selenium-deficient diets. Activities of superoxide dismutase, catalase and non-selenium-glutathione peroxidase were not modified by the different diets. These results suggest that oxy-radical generation may play a major role in hepatic necrosis in vitamin E- and selenium-deficiency.     

Alcoholic liver disease in rats fed ethanol as part of oral or intragastric low-carbohydrate liquid diets

The intragastric administration of ethanol as part of a low-carbohydrate diet results in alcohol hepatotoxicity. We aimed to investigate whether comparable liver injury can be achieved by oral diet intake. Male Sprague-Dawley rats were fed ethanol as part of low-carbohydrate diets for 36-42 days either intragastrically or orally. Liver pathology, blood ethanol concentration, serum alanine amino transferase (ALT), endotoxin level, hepatic CYP2E1 induction, and cytokine profiles were assessed. Both oral and intragastric low-carbohydrate ethanol diets resulted in marked steatosis with additional inflammation and necrosis accompanied by significantly increased serum ALT, high levels of CYP2E1 expression, and production of auto-antibodies against malondialdehyde and hydroxyethyl free radical protein adducts. However, cytokine profiles differed substantially between the groups, with significantly lower mRNA expression of the anti-inflammatory cytokine interleukin 4 observed in rats fed low-carbohydrate diets orally. Inflammation and necrosis were significantly greater in rats receiving low-carbohydrate alcohol diets intragastrically than orally. This was associated with a significant increase in liver tumor necrosis factor alpha and interleukin 1beta gene expression in the intragastric model. Thus, oral low-carbohydrate diets produce more ethanol-induced liver pathology than oral high-carbohydrate diets, but hepatotoxicity is more severe when a low-carbohydrate diet plus ethanol is infused intragastrically and is accompanied by significant increases in levels of proinflammatory cytokines.     

The effects of in vitro lipid peroxidation on the activity of rat liver microsomal glutathione S-transferase from rats supplemented or deficient in antioxidants

Glutathione S-transferases are a group of multifunctional isozymes that play a central role in the detoxification of hydrophobic xenobiotics with electrophilic centers (1). In this study we investigated the effects of in vitro lipid peroxidation on the activity of liver microsomal glutathione S-transferases from rats either supplemented or deficient in both vitamin E and selenium. Increased formation of malondialdehyde (MDA), a by-product of lipid peroxidation, was associated with a decreased activity of rat liver microsomal glutathione S-transferase. The inhibition of glutathione S-transferase occurred rapidly in microsomes from rats fed a diet deficient in both vitamin E and selenium (the B diet) but was delayed for 15 minutes in microsomes from rats fed the same diet but supplemented with these micro-nutrients (B+E+Se diet). Lipid peroxidation inhibits microsomal glutathione S-transferase and this inhibition is modulated by dietary antioxidants.     

Effect of vitamin E on adjuvant arthritis in rats

Adjuvant arthritis was induced in rats fed a diet deficient in or supplemented with vitamin E, and its severity was scored according to the macroscopic findings of their legs, tails, and ears. The average score so obtained was higher in the vitamin E-deficient diet group than in the group of rats supplemented with vitamin E. Whereas the A/G ratio remained depressed in vitamin E-deficient rats, rats on a vitamin E-supplemented diet showed a fast recovery from A/G-ratio depression. The serum levels of beta-glucuronidase and acid phosphatase were elevated after administration of an adjuvant. The serum levels of these lysosomal enzymes showed a remarkable increase in rats fed a vitamin E-deficient diet, while the elevation in lysosomal enzyme levels in rats fed a vitamin E-supplemented diet was inhibited. The levels of thiobarbituric acid (TBA) reactants in the synovia were elevated at 2 weeks after exposure to the adjuvant and were decreased thereafter. In rats maintained on a diet supplemented with vitamin E, on the other hand, the increase in synovial level of TBA reactive substances was inhibited. These observations suggest that the aggravation of adjuvant arthritis may be associated with lipid peroxidation and that antioxidants, such as vitamin E, may be beneficial for arthritis.     

Effect of dietary vitamin E and Santoquin on regenerating rat liver

The influence of dietary vitamin E and Santoquin on lipid peroxidation and liver regeneration in partially-hepatectomized rats was studied. Rats were fed either a basal 10% tocopherol-stripped corn oil diet, the basal diet plus 40 mg dl-alpha-tocopheryl acetate/kg, or the basal diet plus 2 g Santoquin (6-ethoxy-1,2-dihydro-2,2,4-trimethylquinoline)/kg. After 6 weeks, rats fed the antioxidant-deficient diet produced more of the lipid peroxidation product, pentane, than did the rats fed antioxidants. Partial hepatectomy was performed after six and one-half weeks or ten weeks of feeding the diets. At 3 and 6 days after surgery, pentane production was significantly elevated over pre-surgery levels in rats fed the antioxidant-deficient or vitamin E-supplemented diets, but not in rats fed the Santoquin-supplemented diet. Six days after surgery, there were fewer thiobarbituric acid reactants in regenerating liver of Santoquin-fed rats than of vitamin-E fed rats or antioxidant-deficient rats. There was no increase in the 6-day level of thiobarbituric acid reactants over the 3-day level in livers of rats fed Santoquin, while there was an increase in livers of the antioxidant-deficient and vitamin E-supplemented rats. Liver sulfhydryl levels were higher at 3 and 6 days post surgery in the Santoquin-fed rats than in the antioxidant-deficient or vitamin E-supplemented rats. Plasma gamma-glutamyl-transpeptidase activity was not different among the groups of rats. Between the third and sixth day following surgery, liver regeneration was significantly stimulated in Santoquin-fed, but not vitamin E-fed rats. After 11 days, a stimulatory, but not statistically significant, effect of vitamin E was found. Although DNA content of liver was higher at 6 days than at 3 days post surgery, it was not different among the dietary groups, indicating that cell proliferation rather than hypertrophy had occurred. Partial hepatectomy could have altered the ability of the liver to metabolize pentane, thus explaining part of the increased production of pentane. However, the results obtained support the interpretation that elevated levels of dietary antioxidants can be beneficial in terms of reduced lipid peroxidation and increased rates of liver regeneration following liver surgery.     

The effect of dietary menhaden,olive, and coconut oil fed with three levels of vitamin E on plasma and liver lipids and plasma fatty acid composition in rats

The effect of dietary fats with varying degrees of unsaturation in the presence of different concentrations of vitamin E on tissue lipid levels was studied in rats. Rats were fed either menhaden oil, olive oil or coconut oil at 15% levels with either 0.1, 0.3 or 0.6 mg/g of vitamin E as alpha-tocopherol for four weeks. Rat serum and liver were analyzed for total cholesterol, HDL-cholesterol, triacylglycerol and phospholipids. In addition, fatty acid composition of serum lipids was also analyzed. Serum total cholesterol and triacylglycerol were significantly lower in rats fed menhaden oil than in those fed olive or coconut oil, while the HDL-cholesterol was significantly higher in serum of rats fed menhaden and olive oil than in those fed coconut oil. Levels of vitamin E in the diet had only a significant effect on serum cholesterol and liver phospholipids. The Pearson correlation coefficient showed a significant positive relationship between serum triacylglycerol and total cholesterol, and a negative correlation between triacylglycerol and HDL-cholesterol, and between total and HDL-cholesterol.In the liver, total cholesterol was significantly higher in rats fed coconut oil than in rats fed menhaden oil. Total liver phospholipids were lower in rats fed either coconut oil or olive oil compared to those fed menhaden oil, especially with higher levels of vitamin E intake. Higher levels of vitamin E in the diet appear to increase triacylglycerol and phospholipids in livers of rats fed menhaden oil. In the liver a significant negative correlation was observed between phospholipids and cholesterol. The type and degree of unsaturation (polyunsaturated fatty acids in menhaden oil, monounsaturated fatty acids in olive oil and saturated fatty acids in coconut oil) significantly affected plasma and tissue lipids.     

Renal parathyroid hormone-dependent adenylate cyclase activity after repletion of vitamin D-deficient rats with vitamin D-2

Rats fed a diet deficient in both vitamin D and Ca²⁺ exhibited a greater depression of the renal parathyroid hormone (PTH)-dependent adenylate cyclase than was observed in rats fed diets deficient in either vitamin D or calcium. Total serum Ca²⁺ was decreased from a control level of 11.2 mg/dl to 8.5 mg/dl in rats fed the diet deficient in calcium alone, and to 5.4 mg/dl in rats fed the diet deficient in vitamin D. Serum calcium was decreased further to 4.3 mg/dl in rats fed the diet deficient in both vitamin D and Ca²⁺. Serum immunoreactive PTH was significantly elevated over control levels when rats were fed the test diets; however, there were no significant differences between the elevated levels in the three experimental groups. Repletion of rats deficient in vitamin D only with a single oral dose of 3200 I.U. vitamin D-2 resulted in restoration of serum calcium to normal levels, a return of serum PTH to the control state, and an associated increase in PTH-dependent adenylate cyclase activity to the control level by 72 h. Repletion of rats deficient in both vitamin D and Ca²⁺ with the same dose of vitamin D-2 raised serum Ca²⁺ to 7.2 mg/dl by 72 h, but did not cause a reduction in circulating PTH, nor did it result in any significant improvement in the responsiveness of the membrane adenylate cyclase to PTH. These results suggest that elevated PTH is a factor in the down regulation of the PTH-dependent adenylate cyclase, but do not rule out a role for calcium as a regulatory factor.     

The effect of rat strain, diet composition and feeding period on the development of a nutritional model of non-alcoholic fatty liver disease in rats

Non-alcoholic fatty liver disease (NAFLD) is an important cause of liver-related morbidity and mortality. The aim of this work was to establish and characterize a nutritional model of NAFLD in rats. Wistar or Sprague-Dawley male rats were fed ad libitum a standard diet (ST-1, 10 % kcal fat), a medium-fat gelled diet (MFGD, 35 % kcal fat) and a high-fat gelled diet (HFGD, 71 % kcal fat) for 3 or 6 weeks. We examined the serum biochemistry, the hepatic malondialdehyde, reduced glutathione (GSH) and cytokine concentration, the respiration of liver mitochondria, the expression of uncoupling protein-2 (UCP-2) mRNA in the liver and histopathological samples. Feeding with MFGD and HFGD in Wistar rats or HFGD in Sprague-Dawley rats induced small-droplet or mixed steatosis without focal inflammation or necrosis. Compared to the standard diet, there were no significant differences in serum biochemical parameters, except lower concentrations of triacylglycerols in HFGD and MFGD groups. Liver GSH was decreased in rats fed HFGD for 3 weeks in comparison with ST-1. Higher hepatic malondialdehyde was found in both strains of rats fed HFGD for 6 weeks and in Sprague-Dawley groups using MFGD or HFGD for 3 weeks vs. the standard diet. Expression of UCP-2 mRNA was increased in Wistar rats fed MFGD and HFGD for 6 weeks and in Sprague-Dawley rats using HFGD for 6 weeks compared to ST-1. The present study showed that male Wistar and Sprague-Dawley rats fed by HFGD developed comparable simple steatosis without signs of progression to non-alcoholic steatohepatitis under our experimental conditions.     

Supplementation of orotic acid to the casein, but not to egg protein, soy protein, or wheat gluten diets, increases serum ornithine carbamoyltransferase activity

Effects of dietary supplementation of orotic acid to a diet containing the casein protein were compared with diets containing egg protein, soy protein, or wheat gluten on lipid levels in the liver and serum and activities of ornithine carbamoyltransferase (OCT) and alanine aminotransferase in the serum of rats. We found that supplementation of orotic acid to each diet increased the contents of the liver total lipids, triacylglycerol, and phospholipids compared with those not supplemented. The contents of liver total lipids, triacylglycerol, cholesterol, and phospholipids in rats fed the casein diet were significantly higher than those of rats fed the other three diets when orotic acid was supplemented. The levels of triacylglycerol, cholesterol, and phospholipids in the serum of rats fed the casein diet were markedly decreased by addition of orotic acid. The supplementation of orotic acid significantly increased the activities of both serum OCT and alanine aminotransferase in rats fed the casein diet, but not in rats fed the other diets. In conclusion, liver lipid accumulation induced by dietary orotic acid depends on the type of dietary protein. The enhancement of serum OCT activity may result from liver lipid accumulation in rats fed the casein diet supplemented with orotic acid, demonstrating hepatic damage.     

Effect of oral methionine and vitamin E on blood lipid peroxidation in vitamin B6 deficient rats

Lipid peroxidation in blood of vitamin B6 deficient rats was significantly increased when compared to pair-fed controls. The observed increased lipid peroxidation in vitamin B6 deficiency was correlated with high levels of lipids, metal ions and low levels of antioxidants, alpha-tocopherol, ascorbic acid and reduced GSH. Supplementation of methionine or vitamin E along with the vitamin B6 deficient diet restored the levels of antioxidants to near normal and also protected against oxidative stress. However plasma TBARS level as well as total lipids were still elevated in M-B6 diet fed rats and normalized in E-B6-d rats.     

Increased plasma lipidperoxidation in vitamin B-6 deficient rats

Lipidperoxidation in plasma of rats fed with vitamin B-6 deficient diet for a period of 12 weeks was studied with pair-fed controls. Plasma pyridoxal 5'-phosphate, alanine amino transferase and aspartate amino transferase, the markers of vitamin B-6 status, were significantly low in vitamin B-6 deficient rats. Plasma malondialdehyde level, conjugated dienes and lipofuscin like pigments were increased in vitamin B-6 deficiency. Increased levels of plasma lipids, calcium, iron and copper were observed in vitamin B-6 deficiency. Plasma susceptibility to lipidperoxidation was maximal in vitamin B-6 deficiency, upon stimulation by the promotors, Fe2+, Fe3+, Cu2+, ascorbate, t-butyl hydroperoxide and hydrogen peroxide.     

Protein-Vitamin E Relation and the Hemolysis Test

The blood cells of vitamin E deficient rats are hemolyzed by dialuric acid. The percent of hemolysis in the dialuric acid test was higher in rats fed a 5% casein diet than in pair-fed animals receiving 10 or 20% casein diet when a suboptimal amount of α-tocopherol (7 ~ 32 µg per day) was administered. With 1 mg per day of α-tocopherol there was no hemolysis at any protein level. The significance of the results is discussed.     

A diet high in cholesterol and deficient in vitamin E induces lipid peroxidation but does not enhance antioxidant enzyme expression in rat liver

Expression of antioxidant enzymes (AOE), an important mechanism in the protection against oxidative stress, could be modified by the redox status of the cells. The aim of this project was to evaluate the role of vitamin E deficiency in association with a high-cholesterol diet in the hepatic lipid peroxidation and the expression of AOE. Two groups of 6 male rats were fed with a high-cholesterol or a high-cholesterol vitamin E-deficient diet. All animals were sacrificed at 72 days of treatment. Liver lipid peroxidation index (Malondialdehyde; MDA) and hepatic AOE were evaluated. Total liver RNA was extracted, and the steady state messenger RNA (mRNA) levels of glutathion peroxydase, manganese superoxide dismutase, Cu/Zn superoxide dismutase and catalase were examined by northern blot. After 72 days on the diet, a significant increase in the lipid peroxidation index was observed in the vitamin E deficient group (MDA : 4.45 +/- 0.29 nmol/mg protein versus 3.65 +/- 0.1 nmol/mg protein in vitamin E normal group). Despite this oxidative stress, the activities and mRNA levels of liver AOE were not significantly different in the 2 groups. These preliminary results show that chronic vitamin E deficiency associated with high cholesterol diet is able to increase lipid peroxidation without modulation of AOE expression and activity in the liver. This suggests that beneficial effects of dietary vitamin E are due to a plasma antioxidant effect or a cell mediated action, rather than to a specific modulation of cellular enzymes.     

Alterations in plasma total and high density lipoprotein cholesterol levels in hyperlipidemic rats fed diets with varied content of selenium and vitamin E

The effect of dietary selenium and vitamin E on plasma total (TC) and high density lipoprotein cholesterol (HDLC) was evaluated in 54 Sprague Dawley rats fed cholesterol/cholic acid enriched diets. Diets 1, 2, and 3 had no added selenium (low Se) and 0 (low), 60 (adequate), and 600 (high) mg/kg dL alpha tocopheryl acetate added respectively. Sodium selenite at 0.2 mg/kg (adequate Se) was added to diets 4, 5, and 6 and at 4.0 mg/kg (toxic Se) to diet 7, 8, and 9 with the same pattern of vitamin E added to the diet as described above. TC and HDLC were measured using the Kodak Ectachem system. Rats in the low and adequate Se groups fed high vitamin E had lower TC values than rats fed lower vitamin E levels but differences were not significant. In the toxic Se groups, rats fed high vitamin E had significantly (p<0.05) higher plasma TC values than did lower Vitamin E groups. Rats on the high vitamin E diets with low or adequate Se had significantly (p<0.05) higher mean plasma HDLC values when compared to rats fed low or adequate vitamin E diets. HDLC values for animals on Se toxic diets were significantly (p<0.05) lower in rats fed a low vitamin E diet. In rats fed Se deficient and adequate diets, a high vitamin E intake resulted in a decrease in TC and an increase in HDLC. In Se toxic rats, TC was elevated by a high dietary intake of vitamin E as was HDLC with both values being significantly higher than values found in the vitamin E deficient rats. Vitamin E deficiency resulted in a plasma lipid pattern that has been associated with greater cardiovascular disease risk.     

Effect of physical restraint on oxidative stress in mice fed a selenium and vitamin E deficient diet

Physical restraint has been associated with increased oxidative damage to lipid, protein, and DNA. The purpose of this experiment was to determine whether physical restraint would further exacerbate oxidative stress in mice fed a selenium (Se) and vitamin E (VE) deficient diet. Three-week-old mice were fed a Torula yeast diet containing adequate or deficient Se and VE. Menhaden oil was added to the deficient diet to impose an additional oxidative stress. After 4 wk feeding, half the mice in each group were restrained for 5 d in well-ventilated conical tubes for 8 h daily. Mice fed the Se and VE deficient diets had increased liver thiobarbituric acid-reactive substance (TBARS) levels and decreased liver glutathione peroxidase (GPX1) activity and α-tocopherol levels. Plasma corticosterone levels were elevated in restrained mice fed the deficient diet compared to unrestrained mice fed the adequate diet. Restraint had no effect on liver TBARS or α-tocopherol levels. Liver GPX1 activity, however, was lower in restrained mice fed the adequate diet. In addition, liver superoxide dismutase (SOD) activity was lower in the restrained mice fed the adequate or deficient diet. Thus, under our conditions, Se and VE deficient diet, but not restraint, increased lipid peroxidation in mice. Restraint, however, decreased antioxidant protection in mice due to decreased activities of GPX1 and SOD enzymes.     

The role of antioxidant nutrients in preventing hyperbaric oxygen damage to the retina

Vitamin E and selenium play essential roles in preventing in vivo lipid peroxidation and free radical damage. Hyperbaric oxygen (HBO) treatment adversely affected the electroretinograms (ERGs) of rats fed a diet deficient in both vitamin E and selenium (the basal or B diet) or a diet deficient in vitamin E alone (B + Se diet). After 4 weeks of HBO treatment (3.0 ATA or 100% oxygen, 1.5 hours per day, 5 day/week) rats fed the B diet deficient in vitamin E and selenium for 6 weeks showed decreased (p less than 0.05) a-wave amplitudes, 85 +/- 9 microvolts (microV), n = 11, compared with a-waves recorded (150 +/- 10 microV, n = 21) for age matched rats fed an identical diet for 6 weeks but not treated with HBO. After 15 weeks of HBO treatment, rats fed the B + Se diet deficient in vitamin E alone showed decreased (p less than 0.01) a-wave (61 +/- 9 microV, n = 4) and b-wave (253 +/- 23 microV, n = 4) amplitudes compared with a-wave (115 +/- 7 microV, n = 4) and b-wave amplitudes (450 +/- 35 microV, n = 4) for age matched rats fed the same diet but not treated with HBO. Decreased a- or b-wave amplitudes provide evidence of retinal damage. Rats fed a diet supplemented with vitamin E and selenium or vitamin E alone showed no decreases in either a- or b-wave amplitudes after 15 weeks of HBO treatment.     

Effect of the Supplementation of Sulfur Amino Acids to a Diet Containing Soy Protein Isolate on Lipid Metabolism in Rats

The effect of the supplementation of sulfur amino acids to a low casein or soy protein isolate diet on tissue lipid metabolism was investigated. Supplementation of methionine to a 8% casein diet produced a fatty liver in rats, however, supplementation of methionine to a 8.8% soy protein diet (corresponding to a 8% casein diet as to sulfur amino acids content) did not produce a fatty liver. At the level of 8% or less of soy protein in the diet, the accumulation of liver lipids and serum triglyceride was observed. An amino acid mixture simulating the composition of soy protein isolate caused significant accumulation of liver lipids, but serum triglyceride was not changed. Serum cholesterol in rats fed the soy protein diet was lower than that in rats fed the casein diet, but on feeding the amino acid mixtures simulating these protein diets, there was no difference between the two groups. The small differences between soy protein isolate and casein as to lipid metabolism might be due to the small differences in the contents of sulfur amino acids or the specific nature of the soy protein or casein. The supplemental effect of methionine and cystine was also studied. About 60% of total sulfur amino acids could be substituted by cystine for maximum growth.     

Purification, composition, and some properties of rat liver carbamyl phosphate synthetase (ammonia).

Hepatic microsomes prepared from vitamin E deficient and supplemented rats were analyzed for cytochrome P-450 content and drug metabolizing activity. Reduced levels of benzo[α]pyrene hydroxylase and ethylmorphine N-demethylase activities were observed in microsomes derived from rats fed a diet deficient in vitamin E compared to those of control rats. NADPH-mediated destruction of P-450, and pentobarbital and zoxazolamine sleeping times were similar in the two groups. Induction with 3-methylcholanthrene raised the levels of benzo[α]pyrene hydroxylase activity of both supplemented and deficient rats to the same absolute levels. No differences were noted in cytochrome P-450 or P-448 content between control and tocopherol deficient rats, nor did the activity of liver catalase differ between the two dietary groups. Thus, these studies did not demonstrate any impairment of heme protein synthesis in vitamin E deficient rats.     

Free Radical-Induced Liver Injury. I. Effects of Dietary Vitamin E Deficiency on Triacylglycerol Level and its Fatty Acid Profile in Rat Liver

Effects of dietary vitamin E deficiency on the fatty acid compositions of total lipids and phospholipids were studied in several tissues of rats fed a vitamin E-deficient diet for 4, 6, and 9 months. No significant differences were observed between the vitamin E deficiency and controls except in the fatty acid profiles of liver total lipids. Triacylglycerol (TAG) accumulation was found in the liver of rats fed a vitamin E-deficient diet. The levels of TAG-palmitate and -oleate increased particularly in the liver from such animals. The fatty acid compositions of hepatic phospholipids were not affected by the diet. Increased TAG observed in the liver of rats fed a vitamin E-deficient diet was restored to normal when the diet was supplemented with 20 mg α-tocopheryl acetate/kg diet. These findings indicate that dietary vitamin E deficiency causes TAG accumulation in the liver and that the antioxidant, vitamin E, is capable of preventing free radical-induced liver injury.     

Chronic maternal calcium and 25-hydroxyvitamin D deficiency in Wistar rats programs abnormal hepatic gene expression leading to hepatic steatosis in female offspring

Importance of calcium and vitamin D deficiency is well established in adult dyslipidemia. We hypothesized that maternal calcium and vitamin D deficiency could alter offspring's lipid metabolism. Our objective was to investigate the effect of maternal dietary calcium and vitamin D deficiency on lipid metabolism and liver function of the F1 generation offspring. intergenerational calcium-deficient (CaD) and vitamin D-deficient (VDD) models were developed by mating normal male rats with deficient females and continuing maternal-deficient diets through pregnancy and lactation. Offspring were fed on control diet post-weaning and studied till 30 weeks. Lipid profile, serum glutamate pyruvate transaminase (SGPT), calcium and vitamin D levels were analyzed. Liver fat deposition, omega-3 fatty acids level and mRNA expression levels of peroxisome proliferator-activated receptor-alpha (PPAR-α), sterol regulatory element-binding protein 1c (SREBP-1c), interleukin 6 (IL-6), superoxide dismutase 1 (SOD-1) and uncoupling protein 2 (UCP2) were determined. Low serum vitamin D levels with an increase in SGPT and TG levels in CaD and VDD female offspring were observed. Severe liver steatosis with down-regulation of PPAR-α and UCP2 and up-regulation of SREBP-1c, IL-6 and SOD-1 was observed in the female offspring born to deficient dams. CaD and VDD male offspring showed mild steatosis and down-regulation of UCP2 and SOD-1. We conclude that maternal calcium and vitamin D deficiency programs abnormal lipid metabolism and hepatic gene expression in the F1 generation female offspring leading to hepatic steatosis, despite feeding them on control diet post-weaning.
