Purpose: The purpose of this study was to identify the lipid profile ratios as factors affecting disease progress in patients with high-grade primary brain cancers undergoing concurrent chemoradiotherapy (CCRT) and adjuvant chemotherapy. Methods: The levels of lipid profile ratios were evaluated by looking at the total cholesterol (TC) to high-density lipoprotein (HDL)-cholesterol (TC/HDL-c), low-density lipoprotein (LDL)-cholesterol to HDL-cholesterol (LDL-c/HDL-c), and triglycerides to HDL-cholesterol (TG/HDL-c). This descriptive research was conducted 7 months after the initiation of CCRT and adjuvant chemotherapy. Results: A total of 36 patients with newly diagnosed primary malignant brain cancer were included in the study. The levels of lipid profile ratios such as TC/HDL-c, LDL-c/HDL-c, TG/HDL-c were significantly different between the patients with and without disease progress at 7 months after initiation of CCRT and adjuvant chemotherapy. Conclusion: The lipid profile ratios were indicators affecting disease prognosis with tumor-related factors at 7 months after initiation of CCRT and adjuvant chemotherapy. Therefore, lipid profile ratios indicating hyperlipidemia in patients with high-grade brain cancers should be carefully monitored during and after cancer-related therapy.

Cladosiphon okamuranus is edible brown algae cultured commercially and massively at Okinawa coast. Dietary fiber occupying most of C. okamuranus isn't digested and absorbed by digestive enzymes of human. But it is known to prevent and treat constipation as metabolic disease. This study was to investigate the effects of dietary fiber extracted from C. okamuranus on the damage of liver and the blood cholesterol level in the high fat diet-fed rats. The effects were measured by the levels of aspartate aminotransferase (ALT), alanine aminotransferase (AST), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and high density lipoprotein (HDL) in sera. The levels of ALT, AST, TC, TG and LDL were significantly reduced in the C. okamuranus-treated group compared with the high fat diet group. But HDL level was markedly increased. The results showed that the dietary fiber extracts from C. okamuranus have the inhibitive effects of cholesterol biosynthesis in the high fat diet-fed rats.

Dietary karaya saponin and Rhodobacter capsulatus (R. capsulatus) are known to have hypocholesterolemic actions, as reported in our previous studies. This study examined possible synergistic hypocholesterolemic effects of karaya saponin and R. capsulatus in broilers. A total of 150 broilers were allocated into 10 treatments: control, saponin 25 mg, saponin 50 mg, saponin 75 mg, saponin 25 mg+R. capsulatus 0.2 g, saponin 25 mg+R. capsulatus 0.4 g, saponin 50 mg+R. capsulatus 0.2 g, saponin 50 mg+R. capsulatus 0.4 g, saponin 75 mg+R. capsulatus 0.2 g and saponin 75 mg+R. capsulatus 0.4 g. Feed intake and feed efficiency were improved when karaya saponin and R. capsulatus were synergistically supplemented in the diet. Combinations of karaya saponin, especially supplementation of karaya saponin 50 mg+R. capsulatus 0.4 g were shown to have potential hypolipidemic actions in breast and thigh muscle cholesterol and triglycerides, serum cholesterol, low density lipoprotein-cholesterol and triglycerides, as well as improved high density lipoprotein (HDL)-cholesterol (p<0.05). Compared to the control, almost all the treatments significantly increased serum, liver and fecal concentrations of bile acids (p<0.05). Supplementation of both karaya saponin (75 mg) and saponin 50 mg+R. capsulatus 0.4 g reduced palmitic acid (C16:0) and stearic acid (C18:0) in a similar fashion (p<0.05). The ratios of PUFA:SFA or PUFA+MUFA:SFA in the thigh and breast muscle of broilers were greater in karaya saponin and R. capsulatus supplemented groups than in the control group. Thus, our study concluded that supplementation of karaya saponin synergistically with R. capsulatus in the diet of broilers is an effective way to obtain low-cholesterol, low-triglyceride and high HDL-cholesterol enriched poultry meat with a unique fatty acid balance.

Objectives: The aim of this study was to determine the affecting factors of metabolic syndrome (MetS) and it's components in Korean adults in their 30s and 40s. Methods: The present study assessed 1,215 subjects who participated in the Korea National Health and Nutrition Examination Survey in 2014. We analyzed the prevalence rate of MetS and it's components and their affecting factors. Results: The prevalence rate of MetS was 16%. Family history of diabetes mellitus and, low or high saturated fat intake were associated with MetS in males. Low income, low education, excessive sleep, excessive carbohydrate and low saturated fat intake were associated with MetS in females. Triglycerides showed the highest prevalence in males and were related to white collar socioeconomic status, smoking, and obesity. Triglycerides and high-density lipoprotein cholesterol were high in females, and triglycerides were affected by excessive sleep, family history, low saturated fat intake, and obesity. High-density lipoprotein cholesterol was affected by obesity. Conclusions: Because sex differences exist in MetS, it is necessary to intervene through diverse approaches. In particular, a continuous management and preventive intervention for obesity is needed.

In this study, we investigated the effects of green tea and Pueraria radix tea on the production of Apo B$_{100}$ in Hep G$_2$ liver cells and on the expression of the low density lipoprotein (LDL) receptor. Treatment with green tea resulted in a 60.7% decrease on the Apo B$_{100}$ concentration in Hep G$_2$ cells. Pueraria radix tea decreased Apo B$_{100}$ concentration by 63.5% in Hep G$_2$ cells. Green tea and Pueraria radix tea significantly decreased Apo B$_{100}$ concentration by 64.8% and 61.8%, respectively, in the media. Treatment of the cells with green tea and Pueraria radix tea also significantly decreased the intracellular total cholesterol, but total cholesterol concentrations in the media increased by 26.4% (green tea) and 23.6% (Pueraria radix tea) above that measured in the media of control cells. The addition of green tea and Pueraria radix to the media of the Hep Gz cells increased the LDL receptor binding activities by 84.1% and 79.4%, respectively.

The formation of macrophage foam cells stimulated by oxidized low-density lipoprotein (ox-LDL) is deemed an important cause of atherosclerosis. Transcription factor Yin Yang 1 (YY1), which is a universally expressed multifunctional protein, is closely related to cell metabolism disorders such as lipid metabolism, sugar metabolism, and bile acid metabolism. However, whether YY1 is involved in macrophage inflammation and lipid accumulation still remains unknown. After mouse macrophage cell line RAW264.7 cells were induced by ox-LDL, YY1 and proprotein convertase subtilisin/kexin type 9 (PCSK9) expressions were found to be increased while low-density lipoprotein receptor (LDLR) expression was lowly expressed. Subsequently, through reverse transcription-quantitative polymerase chain reaction (RT-qPCR), Western blot analysis, Oil Red O staining and cholesterol quantification, it turned out that silencing of YY1 attenuated the inflammatory response and lipid accumulation in RAW264.7 cells caused by ox-LDL. Moreover, results from the JASPAR database, chromatin immunoprecipitation (ChIP) assay, luciferase reporter assay and Western blot analysis suggested that YY1 activated PCSK9 by binding to PCSK9 promoter and modulated the expression of LDLR in the downstream of PCSK9. In addition, the results of functional experiments demonstrated that the inhibitory effects of YY1 interference on ox-LDL-mediated macrophage inflammation and lipid accumulation were reversed by PCSK9 overexpression. To sum up, YY1 depletion inhibited its activation of PCSK9, thereby reducing cellular inflammatory response, cholesterol homeostasis imbalance, and lipid accumulation caused by ox-LDL.

Objectives This study is to investigate the effects and mechanisms of Imyo-san (IMS) on the obese mice model induced by high-fat diet. Methods Antioxidative capacity was measured by in vitro method. C57BL/6 mice were randomly assigned into 5 groups (n=7). Normal group was fed general diet (Normal). The other 4 groups were fed high fat diet (HFD) with water (Control), with Garcinia gummi-gutta (GG, Garcinia gummi-gutta 200 mg/kg), with low-dose IMS (IMSL, Imyo-san 0.54 g/kg) and with high-dose IMS (IMSH, Imyo-san 1.08 g/kg). Results IMS showed high radical scavenging activity. After 6 week experiment, body weight, food intake, food efficiency ratio (FER), epididymal fat and liver weight, triglyceride (TG), total cholesterol (TC), high density lipoprotein (HDL) cholesterol, low density lipoprotein (LDL) cholesterol, very low density lipoprotein (VLDL) cholesterol, sterol regulatory element-binding protein-1 (SREBP-1), phospho-acetyl-CoA carboxylase (p-ACC), fatty acid synthase (FAS), stearoyl-CoA desaturase-1 (SCD-1), SREBP-2, 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR), phospho-liver kinase B1 (p-LKB1), phospho-AMP-activated protein kinase (p-AMPK), peroxisome proliferator-activated receptor 𝛼 (PPAR𝛼), peroxisome proliferator-activated receptor 𝛾 coactivator-1𝛼 (PGC-1𝛼), uncoupling protein-2 (UCP-2), carnitine palmitoyltransferase 1A (CPT-1A), and histology of liver and epididymal fat were measured and analysed. Body weight gain, FER, liver and epididymal fat weight of IMS groups were significantly decreased. There were significant improvements in blood lipids with less TG, TC, LDL-cholesterol, VLDL-cholesterol and more HDL-cholesterol. Proteins associated with lipid synthesis (SREBP-1, p-ACC, FAS, SCD-1) and cholesterol (SREBP-2, HMGCR) was improved. Factors regulating lipid synthesis and lipid catabolism (p-LKBI, p-AMPK, PPARα, PGC-1α, UCP-2, CPT-1A) were increased. In histological examinations, IMS group had smaller fat droplets than control group. All results increased depending on concentration. Conclusions It can be suggested that IMS has anti-obesity effects with improving lipid metabolism.
