Objectives : We investigated the effects of Sopungsungi-won(Shu!engshunqiyuan) (SSEx1, SSEx2) to treat the metabolic syndrome by the molecular mechanism of regulation of PPAR and modulation of mitochondrial MCAD, VLCAD mRNA expression. Methods : Mouse NMu2Li liver cells and C2C12 skeletal muscle myogenic progenital cells were transiently transfected with expression plasmids for PPAR(PPAR${\alpha}$, PPAR${\delta}$), a luciferase reporter gene construct containing 3 copies of the PPRE from the rat acyl-CoA oxidase gene and ${\beta}$-galactosidase gene. Cells were treated with several concentrated kinds of SSEx1, SSEx2 at the initial time of culture and analyzed PPAR${\alpha}$, PPAR${\delta}$ reporter gene activity using spectrophotometer (405 nm). Total RNA was extracted from SSEx1, SSEx2 and measured mRNA levels of mitochondrial MCAD, VLCAD. Representative RT-PCR bands are shown. Results : 1. SSEx1 increased the expression of PPAR${\alpha}$ reporter gene activities at 0.1 ${\mu}$g/ml (p${\mu}$g/ml (p<0.05), SSEx2 at 0.1 ${\mu}$g/ml (p${\mu}$g/ml (p<0.05) significantly in NMu2Li liver cell lines. 2. SSEx1 increased the expression of PPAR${\alpha}$ reporter gene activities at 1 ${\mu}$g/ml (p${\mu}$g/ml (p${\alpha}$ reporter gene activities in C2C12 skeletal muscle cells. 4. SSEx1 increased the modulation of mitochondrial MCAD mRNA expression (p<0.05) significantly in NMu2Li liver cell lines. 5. SSEx1, SSEx2 both increased the modulation of mitochondrial MCAD mRNA expression (p<0.05) significantly in C2C12 skeletal muscle cells. Conclusions : These results show the SSEx1, SSEx2 can be used as therapeutic agent for metabolic syndrome and it's molecular mechanisms of PPAR more contribute to the activation of PPAR${\alpha}$ then PPAR${\delta}$ reporter gene activities and it's total RNA more contribute to the modulation of mitochondrial MCAD then VLCAD mRNA expression.

Objectives : This study was undertaken to investigate the effects of the GGEx18 ethyl acetate fraction (EF) on lipid accumulation and gene expression of fatty acid-oxidizing enzymes using 3T3-L1 adipocytes, C2C12 skeletal muscle cells, and NMu2Li liver cells. Methods : PPAR${\alpha}$, AMPK and UCPs transactivation was examined in NMu2Li hepatocytes, C2C12 myocytes, and 3T3-L1 preadipocytes using transient transfection assays. Results : 1. Compared with control, EF significantly increased the mRNA expression of VLCAD in 3T3-L1 adipocytes. 2. Compared with control, EF (0.1 ${\mu}g/ml$) significantly inhibited lipid accumulation in 3T3-L1 adipocytes. 3. EF significantly increased the mRNA expression of AMPK${\alpha}$1, AMPK${\alpha}$2 and PPAR${\alpha}$ in C2C12 skeletal muscle cells compared with control. 4. EF significantly increased the mRNA expression of genes involved in fatty acid ${\beta}$-oxidation, such as thiolase, MCAD, and CPT-1 in C2C12 skeletal muscle cells compared with control. 5. EF significantly increased the mRNA expression of UCP2 involved in energy expenditure in C2C12 skeletal muscle cells compared with control. 6. Compared with control, EF (10 ${\mu}g/ml$) significantly inhibited lipid accumulation in C2C12 skeletal muscle cells. 7. EF (10 ${\mu}g/ml$) significantly increased the mRNA expression of ACOX, HD, VLCAD and MCAD in NMu2Li liver cells compared with control. Conclusions : These results suggest that EF may prevent obesity by increasing the mRNA expression of mitochondrial fatty acid ${\beta}$-oxidizing enzymes in 3T3-L1 adipocytes, by not only regulating the fatty acid oxidation through activation of AMPK and PPAR${\alpha}$, but also increasing the UCP2 mRNA expression in C2C12 skeletal muscle cells, and by stimulating the mRNA expression of fatty acid-oxidizing enzymes in NMu2Li liver cells.

Objectives: This study was designed to investigate anti-obesity effects the improvement effects of Gyejibongnyeong-hwan and Gyejibongnyeong-hwan-Gangji-hwan (CIPPDF) in a ob/ob mouse model. Methods: Seven-week old mice (wild-type C57BL/6J and ob/ob) were used for all experiments. Wild-type C57BL/6J mice were used as normal group and obese ob/ob mice were randomly divided into 4 groups. a normal group given a standard diet, an obese control group given a standard diet with CIPP (300 mg/kg), CIPPDF (1) (300+300 mg/kg), CIPPDF (2) (300+600 mg/kg) respectively. After 10 weeks of treatment, body weight gain, feeding efficiency ratio, blood lipid markers, mRNA levels of genes involved in fatty acid ${\beta}-oxidation$ and lipogenesis in in-vivo, were examined. Results: 1. Body weight gain and Feeding efficiency ratio were significantly decreased in CIPPDF (1) compared with control. Fat mass was significantly decreased in CIPPDF (2) in EAT compared with control. 2. Consistent their effects on body weight gain and fat mass, circulating concentrations of LDL-cholesterol were decreased in CIPPDF (1), CIPPDF (2) groups compared with control. 3. MCAD mRNA levels of genes was increased in CIPPDF (1), CIPPDF (2) groups in the liver, epididymal adipose tissue compared with control. VLCAD mRNA levels of genes was increased in CIPPDF (1), CIPPDF (2) groups in the skeletal muscle compared with control. 4. $PPAR{\gamma}$ mRNA was decreased in CIPPDF (1) in the liver compared with control. SCD1 mRNA was decreased in CIPPDF (1), CIPPDF (2) groups in the epididymal adipose tissue compared with control. Conclusions: In conclusion, These results suggest that CIPPDF not only decrease feeding efficiency ratio, and LDL-cholesterol, but also reduce EAT fat mass contributing to the improvement of ovesity. CIPPDF also were increased in mRNA levels of genes involved in fatty acid ${\beta}-oxidation$ and decreased in mRNA levels of genes involved in lipogenesis.

The peroxisome proliferator-activated receptor ${\alpha}$ ($PPAR{\alpha}$) is a nuclear transcription factor that plays a central role in lipid and lipoprotein metabolism. To investigate whether swim training improves obesity and lipid metabolism through $PPAR{\alpha}$ activation in female sham-operated (Sham) and ovariectomized (OVX) mice, we measured body weight, visceral adipose tissue mass, serum free fatty acid at 6 weeks as well as the expression of hepatic $PPAR{\alpha}$ target genes involved in fatty acid oxidation. Swim-trained mice had decreased body weight, visceral adipose tissue mass and serum free fatty acid levels compared to high fat diet fed control mice in both female Sham and OVX mice. These reductions were more prominent in OVX than in Sham mice. Swim training significantly increased hepatic mRNA levels of $PPAR{\alpha}$ target genes responsible for mitochondrial fatty acid ${\beta}$-oxidation, such as carnitine palmitoyltransgerase-1 (CPT-1), very long chain acyl-CoA dehydrogenase (VLCAD), and medium chain acyl-CoA dehydrogenase (MCAD) in OVX mice. However, swim trained female Sham mice did not increase hepatic mRNA levels of $PPAR{\alpha}$ target genes responsible for mitochondrial fatty acid ${\beta}$-oxidation compared to Sham control mice. These results indicate that swim training differentially regulates body weight and adipose tissue mass between OVX and Sham mice, at least in part due to differences in liver $PPAR{\alpha}$ activation.

Objectives : This study was undertaken to verify the modulation mechanism of Gyeongshingangjeehwan18 (GGEx18) in ob/ob male mice. Methods : Eight-week old mice (wild-type C57BL/6J and ob/ob) were used for all experiments. Wild-type C57BL/6J mice were used as lean control and obese ob/ob mice were randomly divided into 5 groups : obese control, GGEx15 (Ephedra sinica Stapf + Rheum palmatum L.), GGEx16 (Ephedra sinica Stapf + Laminaria japonica Aresch), GGEx17 (Rheum palmatum L. + Laminaria japonica Aresch), and GGEx18 (Ephedra sinica Stapf + Laminaria japonica Aresch + Rheum palmatum L.). After mice were treated with several kinds of GGEx for 11 weeks, the mRNA expression of peroxisome proliferator-activated receptor (PPAR) target genes and uncoupling protein (UCP) were measured. In addition, $PPAR{\alpha}$ and $PPAR{\beta}$ transactivation was examined in NMu2Li hepatocytes, C2C12 myocytes, and 3T3-L1 preadipocytes using transient transfection assays. Results : 1. Hepatic $PPAR{\alpha}$ target genes, such as ACOX and VLCAD mRNA levels were significantly increased by GGEx18 compared with obese controls. In skeletal muscle, LCAD mRNA expression was stimulated by GGEx16, GGEx17, and GGEx18, whereas MCAD mRNA expression by GGEx17 and GGEx18. $PPAR{\beta}$ target LPL mRNA levels were also increased by GGEx16, GGEx17, and GGEx18 in skeletal muscle, but adipose LPL mRNA levels were decreased. In addition, GGEx18 upregulated UCP mRNA expression in skeletal muslce. 2. $PPAR{\alpha}$ reporter gene expression was increased by GGEx18 in NMu2Li cells compared with vehicle. $PPAR{\alpha}$ and $PPAR{\beta}$ reporter activities were also increased by all GGEx treatments in C2C12 and 3T3-L1 cells. Conclusions : These results suggest that GGEx can act as $PPAR{\alpha}$ and $PPAR{\beta}$ activators, and that GGEx may regulate obesity by stimulating $PPAR{\alpha}$, $PPAR{\beta}$, and UCP activity. Of the 4 compositions, GGEx18 seems to be most effective in improving obesity and lipid disorders.
