     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0054]    Further embodiments herein may be formed by supplementing an embodiment with one or more element from any one or more other embodiment herein, and/or substituting one or more element from one embodiment with one or more element from one or more other embodiment herein. 
       EXAMPLES  
       [0055]    The following non-limiting examples are provided to illustrate particular embodiments. The embodiments throughout may be supplemented with one or more detail from one or more example below, and/or one or more element from an embodiment may be substituted with one or more detail from one or more example below. 
         [0056]    The benefits of statins or DPA-1 in cardiovascular system may not only be due to their cholesterol-lowering effects, but also, to their pleiotropic effects, predominantly due to inhibiting isoprenoid synthesis, the products of which are important lipid attachments for intracellular signaling (Murtola et al., 2008). Besides cholesterol, application of mevalonate to liver cells results in biosynthesis of the isoprenoid compounds farnesyl pyrophosphate (FPP) and geranylgeranyl pyrophosphate (GGPP), levels of which are reduced by statins. In addition, application of GGPP, FPP and mevanolate to cells can stop the functionally processing of HMGR; increased levels of GTP-RhoA after GGPP depletion have enhanced Rho effector signaling (Waiczies et al., 2007). 
         [0057]    ROCK has newly emerged as the principal mechanisms underlying the pleiotropic effects of statins and DPA-1 has been described to inhibit RhoA/ROCK via NO/cGMP-dependent pathway. eNOS, the main source of endothelium-derived NO, related to RhoA/ROCK, appears to be a therapeutic target in lipid-lowering and treatment of atherosclerosis. Decrease in Rho GTPase responses increases the production and bioavailability of endothelium-derived NO. The regulation of eNOS by Rho GTPases is an important mechanism underlying the cardiovascular protective effect. Increase of eNOS/cGMP and decrease of RhoA/ROCK contribute to pleiotropic activities of HMGR antagonists. 
         [0058]    Anti-hypercholesterolemia agent is required to increase HDL, because low HDL cholesterol levels constitute an independent risk factor to cardiovascular disease; increased HDL can protects against atherosclerosis through the action reversing cholesterol transport pathway (Brewer, 2004). Liver X receptor (LXRα ) regulates the expression of ABCA1, which is involved in the HDL-related reverse cholesterol transport (RCT) pathway (Ando et al., 2004). 
         [0059]    Peroxisome proliferator activated receptors (PPARs) are found in all mammalian species and each subclass has unique tissue specificity and functions (Peters et al., 2005). Among them, PPAR-γ is expressed in controls of adipocyte differentiation, fat storage and inflammation (Tontonoz et al., 1995). Cellular cholesterol metabolism is accomplished, in part, by PPARs and LXRα (Argmann et al., 2005). Activation of isoprenoid can produce FPP and GGPP that has been demonstrated to inhibit ABCA1, directly through antagonism of LXRα and indirectly through activated geranylgeranylation of RhoA (Argmann et al., 2005).

         [0072]    In accordance with a further aspect of the present aspects, depending on the desired clinical use and the effect, the adaptable administration method of DPAs pharmaceutical composition includes one selected from a group consisting of an oral administration, an intravenous injection, a subcutaneous injection, an intraperitoneal injection, an intramuscular injection and a sublingual administration. The DPAs pharmaceutical composition providing a medical effect for inhibiting obesity related condition or disease, and more particularly to inhibiting feeding-rate of obesity, hyperlipidemia, over weight of adipose tissues and maintaining metabolic homeostasis. In another embodiment, said obesity related condition means incorporate decrease adipose tissue and increase lean body mass, beneficial to consumers who are willing to eat lack fat of animal muscle food. The farmers also economically feed the animals by a less amount of foods in the presence of food-additives containing DPAs. Perferably, said, animal included human and non-human animal as meat poultry (beef, lamb, pork, chicken, dark, goose, pigeon, goat, and horse). 
         [0073]    The term excipients or “pharmaceutically acceptable carrier or excipients” and “bio-available carriers or excipients” mentioned above include any appropriate compounds known to be used for preparing the dosage form, such as the solvent, the dispersing agent, the coating, the anti-bacterial or anti-fungal agent and the preserving agent or the delayed absorbent. Usually, such kind of carrier or excipient does not have the therapeutic activity itself Each formulation prepared by combining the derivatives disclosed in the present aspects and the pharmaceutically acceptable carriers or excipients will not cause the undesired effect, allergy or other inappropriate effects while being administered to an animal or human. Accordingly, the derivatives disclosed in the present aspects in combination with the pharmaceutically acceptable carrier or excipients are adaptable in the clinical usage and in the human. A therapeutic effect can be achieved by using the dosage form in the present aspects by the local or sublingual administration via the venous, oral, and inhalation routes or via the nasal, rectal and vaginal routes. About 0.1 mg to 1000 mg per day of the active ingredient is administered for the patients of various diseases. 
         [0074]    The carrier is varied with each formulation, and the sterile injection composition can be dissolved or suspended in the non-toxic intravenous injection diluents or solvent such as 1,3-butanediol. Among these carriers, the acceptable carrier may be mannitol or water. Besides, the fixing oil or the synthetic glycerol ester or di-glycerol ester is the commonly used solvent. The fatty acid such as the oleic acid, the olive oil or the castor oil and the glycerol ester derivatives thereof, especially the oxy-acetylated type, may serve as the oil for preparing the injection and as the naturally pharmaceutical acceptable oil. Such oil solution or suspension may include the long chain alcohol diluents or the dispersing agent, the carboxylate methyl cellulose (CMC) or the analogous dispersing agents, such as methyl cellulose, ethyl cellulose and hydroxyl ethyl methyl cellulose (HEMC). Other carriers are common surfactant such as Tween and Spans or other analogous emulsion, or the pharmaceutically acceptable solid, liquid or other bio-avaliable enhancing agent used for developing the formulation that is used in the pharmaceutical industry. 
         [0075]    The composition for oral administration adopts any oral acceptable formulation, which includes capsule, tablet, pill, emulsion, aqueous suspension, dispersing agent and solvent. The carrier is generally used in the oral formulation. Taking the tablet as an example, the carrier may be the lactose, the corn starch and the lubricant, and the magnesium stearate is the basic additive. The diluents used in the capsule include the lactose and the dried corn starch. For preparing the aqueous suspension or the emulsion formulation, the active ingredient is suspended or dissolved in an oil interface in combination with the emulsion or the suspending agent, and the appropriate amount of the sweetening agent, the flavors or the pigment is added as needed. 
         [0076]    The nasal aerosol or inhalation composition may be prepared according to the well-known preparation techniques. For example, the bioavailability can be increased by dissolving the composition in the phosphate buffer saline and adding the benzyl alcohol or other appropriate preservative, or the absorption enhancing agent. The compound of the present aspects may be formulated as suppositories for rectal or virginal administration. 
         [0077]    The compound of the present aspects can also be administered intravenously, as well as subcutaneously, parentally, muscular, or by the intra-articular, intracranial, intra-articular fluid and intra-spinal injections, the aortic injection, the sterna injection, the intra-lesion injection or other appropriate administrations. 
         [0078]    The term “hyperlipemia or hyperlipidemia” used throughout the specification of the present invention refers to an imbalance between resting energy intake and energy expenditure. Such an increase in fat storage can occur independently of adipogenesis, i.e., the production of new fat cells. Furthermore, many complications of obesity and body weight gain result from improper storage of fat eg. total cholesterol, triglyceride, high density lipoprotein etc., in liver. 
         [0079]    Obesity and fatty liver disease of animals is induced by free fatty acid secretion from visceral fat tissue through lipolysis of adipocytes. However, excess lipolysis of adipocytes, such as stimulated by β-agonist administration in obesity animal caused by high-fat-diet (HFD), hydrolyze intracellular triglyceride and accumulate fatty acid levels via hormone-sensitive lipase (HSL), enforcing fatty acids secretion toward extracellular domain and thus reducing the size of adipose tissues. 
         [0080]    Adipose tissue, which is primarily composed of adipocytes, is crucial for maintaining energy and metabolic homeostasis. Obesity and fatty liver disease of animals is induced by free fatty acid secretion from visceral fat tissue through lipolysis of adipocytes. However, excess lipolysis of adipocytes, such as stimulated by β-agonist administration in obesity animal caused by high-fat-diet (HFD), hydrolyze intracellular triglyceride via hormone-sensitive lipase (HSL), enforcing fatty acids secretion toward extracellular domain and thus reducing the size or weight of adipose tissues. These events decrease adipose tissue and increase lean body mass, beneficial to consumers who are willing to eat lack fat of animal muscle food. The farmers also economically feed the animals by a less amount of foods in the presence of food-additives containing one of DPAs derivative compound and DPAs amine complex compound. 
         [0081]    The components of adipose tissues majorly include epididymal fat pads was reduced by treatments with DPAs in HFD-induced obesity mice. This invention suggests that cGMP-enhancer DPAs inhibit the obesity, via restoring PPARγ -regulated eNOS and inactivating RhoA/ROCK to enhance the lipolysis of adipocytes and reduced adipose tissue weight. 
         [0082]    Lipolysis Activity in 3-T-3 adipocytes and Protein Expression 
         [0083]    Elevated cAMP/cGMP acts as second messengers to activate hormone sensitive lipase (HSL). HSL, the rate-limiting enzyme regulating adipocyte lipolysis, then catalyzes the hydrolysis of triglycerides and results in the release of glycerol and FFA (increased lipolysis). Phosphodiesterases (PDE) are enzymes that hydrolyze cAMP to 5′-AMP. This action results in a decrease in lipolysis. PDE inhibitors increase intracellular cAMP levels. 3-isobutyl-1-methylxanthine (IBMX), a non-specific inhibitor of cAMP phosphodiesterases (PDE), is used as referenced PDE inhibitors. Isoproterenol, a non-specific beta-adrenergic agonist is used as the positive control if your test compounds affect lipolysis via beta-adrenergic receptors. In this study, DPA-1, a xanthine analogue, was used as cGMP-enhancer to activate HSL. Increased expression of HSL and phosphorylated HSL (p-HSL) by DPA-1 indicates the increased lipolysis activity. In addition, PPAR/eNOS in adipocytes is up-regulated by DPA-1 and thus led to increased HSL and p-HSL.

         [0085]    HepG2 cells were incubated with mevalonate (100 μM-1000 μM) for 24 h. HepG2 cells were preincubated for 1 h with mevalonate(100 μM) than treated DPA-1 (10 −5  M) or simvastatin (10 −5  M) to measure HMG-Co A Reductase protein expression by Western blotting analyses.  FIG. 1  shows the effects of DPAs and simvastatin on HMG CoA Reductase (HMGR), ROCKII, PPARγ and ABCA1 expression of mice liver. HepG2 cells were incubated for 24 h with increasing doses of DPA-1 (10 −9 -10 −5  M) ( FIG. 2A ) or simvastatin (10 −9 -10 −5 M) ( FIG. 2B ) by Western blot analysis.  FIG. 2  shows the effects of DPAs and simvastatin and mevalonate on HMGR protein expression of HepG2 cell. HepG2 cells were incubated for 24 h with increasing doses of DPA-1 (10 −9 -10 −5 M) ( FIG. 3A ) by Western blot analysis. As shown in  FIG. 3 , eNOS is increased by DPA-1 (10 −9 ˜10 −4  μM) in HepG2 cells, contributing to NO-releasing and cGMP-enhancing activity. 
         [0086]    Feed Back-Regulation on HMGR Expression 
         [0087]    As shown in  FIG. 4 , application of mevalonate (10 −5 M) in HepG2 cells reduced expression of HMGR; its combination with DPA-1 (10 −5 M) reversed this inhibition, indicating their competitive feed-back regulation on HMGR. 
         [0088]    HepG2 cells were incubated with DPA-1 (10 −9 -10 −5  M) ( FIG. 4A ) or simvastatin (10 −9 -10 −5  M) ( FIG. 4B ) for 24 h.  FIG. 4  shows the effects of DPA-1 and simvastatin on HMGR expressions in HepG2 cells. HepG2 cells were incubated with DPA-1 (10-9-10-5 M) ( FIG. 5A ) or simvastatin (10-9-10-5 M) ( FIG. 5B ) for 24 h.  FIG. 5  shows the effects of DPA-1 and simvastatin on PPARγ and ABCA1 of HepG2 cells. HepG2 cells were incubated with DPA-1 (10 −9 -10 −5  M) or simvastatin (10 −9 -10 −5  M) for 24 h.  FIG. 6  shows the effects of DPA-1 and simvastatin on ApoA 1. 
         [0089]      FIG. 7  shows the effects of DPA-1 and simvastati on ROCKII, PPAR and ABCA1. HepG2 cells were incubated with GGPP (10 μM) or FPP (10 μM) alone and GGPP ( FIG. 7A ) or FPP ( FIG. 7B ) with DPA-1 (10 −9 -10 −5  M) for 24 h. HepG2 cells were incubated with GGPP (10 μM) or FPP (10 μM) alone and GGPP or FPP with DPA-1 (10 −9 -10 −5 M) for 24 h.  FIG. 8  shows the effects of DPA-1 and simvastatin on Rho A and ROCK II. 
         [0090]    RhoA/ROCKII Inactivation 
         [0091]    In HepG2 cells, ROCKII (Rho kinase II) is the downstream effector of RhoA in hepatic cellular signaling. DPA-1 or simvastatin (10 −9 -10 −5  M) concentration-dependently reduced ROCKII protein expression, indicating due to inhibited translocation of RhoA ( FIG. 7 ). 
         [0092]    Enhancement of ABCA1, ApoA1, LXRα and PPAR-γ 
         [0093]    In HepG2 cells, DPA-1 or simvastatin (10 −9 -10 −5 M) increased cells levels of PPAR-γ and enhanced ABCA1 (ATP-binding cassette transporter A1) and ApoA1(apolipoprotein A-1) expression, indicating affecting the lipid metabolism toward HDL formation. 
         [0094]    HepG2 cells were incubated with GGPP (10 μM) or FPP (10 μM) alone and GGPP or FPP with DPA-1 (10 −9 -10 −5 M) for 24 h.  FIG. 9  shows the effects of DPA-1 on PPARγ, ABCA1 and in the presence of FPP and GGPP. HepG2 cells were incubated With DPA-1 (10 −9 -10 −5 M) for 24 h.  FIG. 10  shows the effects of DPA-1 on LXR-α.  FIG. 11  shows the effects of DPA-1 on eNOS expression. DPA-1 concentration-dependently increases eNOS expression of HePG2 cells. 
         [0095]    Reversal of GGPP- and FPP-induced inhibition of RhoA/ROCKII and PPAR-γ/ABCA1 
         [0096]    Exogenous application of GGPP (geranylgeranyl pyrophosphate) and FPP (farnesyl pyrophosphate) increased RhoA/ROCKII expression, but DPA-1 (10 −9 -10 −5  M) reversed this phenomenon in HepG2 cells. Incubation of cells with FPP or GGPP (10 μM) alone decreased the expression of PPAR-γ and ABCA1, respectively. However, incubation of FPP or GGPP with DPA-1 (10 −9 -10 −5 M), reversed the reduction of PPAR-γ and ABCA1, respectively. 
         [0097]    Pretreatment with C3 exoenzyme, Y27632, Rp-8-pPCT-cGMPs 
         [0098]    RhoA antagonist C3 exoenzyme (5 μg/ml), ROCK antagonist Y27632 (10 μM) and cGMP antagonist Rp-8-pPCT-cGMPs (10 μM) all increased ROCKII expression but were reversed by DPA-1 (10 μM) in HepG2 cells.

         [0099]    Effects on Body Weight Gain and Food Intake 
         [0100]    Table 3 shows the body weight gain and food intake of animals fed with the experimental diets. Consumption of HFD (high fat diet fed group) for 8 weeks significantly increased food intake and body weight gain (p&lt;0.05). The body weight gain of HFD was significantly increased by 2.3-fold compared to CTL (control) group (p&lt;0.05). Surprisingly, DPA-1 (1, 2.5, 5 mg/kg p.o.) supplementation did not affect food intake in HFD fed mice. However, supplementation of DPA-1 in the HFD group significantly reduced the body weight gain compared to HFD group (p&lt;0.05). In comparison, simvastatin and DPA-1-Simvastatin acid also affected body weight.

         [0101]    Effects on Plasma Lipid Profiles 
         [0102]    Table 5 shows the plasma TG, total cholesterol, HDL cholesterol and LDL cholesterol levels of experimental animals. In this study, the HFD caused dramatic increases in serum TG, total cholesterol and LDL cholesterol compared with the non-HFD group, by 1.6-, 2.6- and 5.2-fold, respectively. The HFD-induced hypercholesterolemia was significantly improved by DPA-1 supplementation. The HFD+DPA-1 (1, 2.5, 5 mg/kg p.o.) group had significantly reduced plasma TG (Triglyceride), total cholesterol and LDL cholesterol, compared with the HFD group. Particularly, the HDL (low-density lipoprotein) cholesterol level was significantly increased by DPA-1 (1, 2.5, 5 mg/kg p.o.) and simvastatin (5 mg/kg p.o.); the HDL value caused by DPA-1 (2.5 mg/kg) almost equal to that caused by simvastatin (5 mg/kg), indicating DPA-1 with 2 fold potency of simvastatin for increasing HDL.

         [0103]    Table 7 shows the oral administration of HFD significantly increased body-weight growth at week 18 and at week-23. All treatments significantly reduced HDF-induced body-weight gain. The body-weight gain at week-17 is significantly different from week-10. Dose-dependent responses to 1, 2.5 and 5 mg/kg of treatment were found (P&lt;0.05). The body-weight gain at week-23 was insignificantly decreased by treatment (A group, 1 mg/kg), compared to week-18. However, this decrease at week-23 was significantly different from that of week-18 by treatment (B group, 2.5 mg/kg) and (C group, 5 mg/kg).

         [0104]    Table 8 shows the Feeding-Rate is the percentage of food intake during one week. Obesity mice aging 18 weeks were administered with high fat diet (HFD) and mice with similar body weight were collected for experiments. Other analogues were administered according to same way. C57BL/6J mice were sacrificed at week 23; *P&lt;0.05 vs HFD; #P&lt;0.05 vs week-18; DPA-2, DPA-3 and DPA-4 were shown as the same manner. They all reduced feeding rate significantly at week-23 or week 22. DPAs save the consumption of food additives dose-dependently, leading to decreasing the feeding-rate of HFD.

         [0108]    Expression/Activity of HMGR 
         [0109]    To demonstrate that DPA-1, simvastatin and DPA-1-Simvastatin Acid can affect HMGR (HMG-CoA reductase), we measured the HMGR protein expression and activity in HepG2 cell. Incubation of HepG2 cells with them for 24 h, significantly enhanced HMGR protein expressions. DPA-1, simvastatin and DPA-1-Simvastatin Acid (10 −9 -10 −5  μM) all concentration-dependently inhibited NADPH, the represented HMGR activity. However, supplementation of DPA-1 (2.5-5 mg/kg) and simvastatin (5 mg/kg) in the HFD group significantly reduced the HMGR reductase. 
         [0110]    The term excipients or “pharmaceutically acceptable carrier or excipients” and “bio-available carriers or excipients” above-mentioned include any appropriate compounds known to be used for preparing the dosage form, such as the solvent, the dispersing agent, the coating, the anti-bacterial or anti-fungal agent and the preserving agent or the delayed absorbent. Usually, such kind of carrier or excipient does not have the therapeutic activity itself Each formulation prepared by combining the derivatives disclosed in the present invention and the pharmaceutically acceptable carriers or excipients will not cause the undesired effect, allergy or other inappropriate effects while being administered to an animal or human. Accordingly, the derivatives disclosed in the present invention in combination with the pharmaceutically acceptable carrier or excipients are adaptable in the clinical usage and in the human. A therapeutic effect can be achieved by using the dosage form in the present invention by the local or sublingual administration via the venous, oral, and inhalation routes or via the nasal, rectal and vaginal routes. About 0.1 mg to 1000 mg per day of the active ingredient is administered for the patients of various diseases. 
         [0111]    The carrier is varied with each formulation, and the sterile injection composition can be dissolved or suspended in the non-toxic intravenous injection diluents or solvent such as 1,3-butanediol. Among these carriers, the acceptable carrier may be mannitol or water. Besides, the fixing oil or the synthetic glycerol ester or di-glycerol ester is the commonly used solvent. The fatty acid such as the oleic acid, the olive oil or the castor oil and the glycerol ester derivatives thereof, especially the oxy-acetylated type, may serve as the oil for preparing the injection and as the naturally pharmaceutical acceptable oil. Such oil solution or suspension may include the long chain alcohol diluents or the dispersing agent, the carboxylmethyl cellulose or the analogous dispersing agent. Other carriers are common surfactant such as Tween and Spans or other analogous emulsion, or the pharmaceutically acceptable solid, liquid or other bio-avaliable enhancing agent used for developing the formulation that used in the pharmaceutical industry. 
         [0112]    The composition for oral administration adopts any oral acceptable formulation, which includes capsule, tablet, pill, emulsion, aqueous suspension, dispersing agent and solvent. The carrier generally used in the oral formulation, taking the tablet as an example, the carrier may be the lactose, the corn starch and the lubricant, and the magnesium stearate is the basic additive. The diluents used in the capsule include the lactose and the dried corn starch. For preparing the aqueous suspension or the emulsion formulation, the active ingredient is suspended or dissolved in an oil interface in combination with the emulsion or the suspending agent, and the appropriate amount of the sweetening agent, the flavors or the pigment is added as needed. 
         [0113]    The nasal aerosol or inhalation composition may be prepared according to the well-known preparation techniques. For example, the bioavailability can be increased by dissolving the composition in the phosphate buffer saline and adding the benzyl alcohol or other appropriate preservative, or the absorption enhancing agent. The compound of the present invention may be formulated as suppositories for rectal or virginal administration. 
         [0114]    The compound of the present invention can also be administered intravenously, as well as subcutaneously, parentally, muscular, or by the intra-articular, intracranial, intra-articular fluid and intra-spinal injections, the aortic injection, the sterna injection, the intra-lesion injection or other appropriate administrations. 
         [0115]    Animal Model of Hyperlipidemia 
         [0116]    C57BL/6J mice were fed with high-fat diet (HFD) to produce a model of hyperlipidemia. At 6-week old, the C57BL/6J mice were randomly divided into 5 groups, two control and three treatment groups. The control mice received either a regular diet or HFD and the treatment group was fed with a HFD and DPA-1 (1, 2.5, 5 mg/kg, p.o.), or simvastatin (5 mg/kg), respectively, for a period of 8 weeks. Compared to two control groups, the body-weight gain and lipid levels were measured in HFD group. In the measurement of eNOS and ROCKII expression of liver, mice (20˜25 g) were administered with DPASor simvastatin and sacrificed to obtain liver at 1 and 24 hours. 
         [0117]    Animal Feeding via HFD and Treatment with DPAs on Mice Body-Weight Gain 
         [0118]    Male C57BL/6J mice (aging 10 weeks) were housed one-mouse to each-cage fully loaded with 50 g diet, maintained at 25° C. on a 12-h light-dark cycle, and provided high-fat diet (HFD) and water ad libitium. The care of mice, as well as all procedure used in this study, were done in accordance with National Institutes of Health animal care guidelines. Consumed or fed diet, as food-intake was calculated as a reference of feeding rate. 
         [0119]    Serum Cholesterol and Lipids 
         [0120]    Mice serum was collected by centrifugation. Serum triglyceride, cholesterol, LDL and HDL levels were measured using a Hitachi Clinical Analyzer 7070 (Hitachi High-Technologies Co. Tokyo, Japan). 
         [0121]    Western Blotting Analyses of Proteins in 3-T-3 Cell Culture 
         [0122]    The 3T3-L1 adipocytes in 100 mm dishes were stimulated with MDI and DPA-1 for the indicated time, and whole cell extracts were prepared by lysing the cells in extraction buffer (RIPA buffer) containing 50 mmol/L Tris(hydroxymethyl)aminomethane (Tris)/HCl, pH 8.0, 150 mmol/L NaCl, 1% Nonidet-P40, 1% sodium deoxycholate, 0.1% sodium dodecyl sulfate (SDS), 0.1 mmol/L dithiothreitol (DTT), 0.05 mmol/L phenylmethyl-sufonyl-fluoride (PMSF), 0.002 mg/mL aprotinin, 0.002 mg/mL leupeptin and 1 mmol/L NaVO3 after stimulation. The protein concentration was quantified with Bio-Rad Dc protein assay reagent (Bio-Rad, Hercules, USA). Equal amounts of protein were mixed with SDS sample buffer and incubated for 5 min at 100° C. before loading. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) was performed according to the method of Amersham Biosciences. Immunoreactive bands were detected by means of an ECL plus western blotting detection system (Amersham Biosciences). The chemiluminescent signals were scanned from films (Nippon Polaroid K.K., Tokyo, Japan). 
         [0123]    Protein Expression by Western Blotting Analysis of Mice Liver and HepG2 Cells 
         [0124]    Liver tissues of mice were isolated and cut into small chips and HepG2 cell were placed into an extraction buffer (Tris 10 mM, pH 7.0, NaCl 140 mM, PMSF 2 mM, DTT 5 mM, NP-40 0.5%, pepstatin A 0.05 mM and leupeptin 0.2 mM) for protein extraction, and then centrifuged at 12,500 g for 30 min, respectively. To measure the expression levels of proteins, the total proteins were extracted and measured the protein by Western blotting analyses. Briefly, the protein extract was boiled to a ratio of 4:1 with sample buffer (Tris 100 mM, pH 6.8, glycerol 20%, SDS 4% and bromophenol blue 0.2%). Electrophoresis was performed using 10% SDS-polyacrylamide gel (2 hr, 100 V, 40 mA, 50 mg protein per lane). Separated proteins were transferred to PVDF membranes treated with 5% fat-free milk powder to block the nonspecific IgGs (90 min, 100 V) and incubated for 1 hr with specific protein antibody. The blot was then incubated with anti-mouse or anti-goat IgG linked to alkaline phosphatase (1:1000) for 1 hr. Immunoreactive bands were visualized using horseradish peroxidase-conjugated secondary antibodies and subsequent ECL detection (GE Healthcare Bio-Sciences Corp., Piscataway, N.J., U.S.A.). Mouse or rabbit monoclonal antibody of ROCKII (Upstate, N.Y., U.S.A.), RhoA (Santa Cruze, Calif., U.S.A.), HMG CoA reductase (Upstate, N.Y, U.S.A.), PPAR-γ (Santa Cruze, Calif., U.S.A.), ABCA1 (Cell Signaling, NY, U.S.A.), APOA-1 (Abcam, N.Y., U.S.A.), LXR (Santa Cruze, Calif., U.S.A.) and the loading control protein β-actin (Sigma-Adrich, MO) were used in our Western blot analyses.
