Description

TECHNICAL FIELD The present invention relates to an anti-obesity composition comprising an extract of Alaska pollack as an active ingredient,

The present invention relates to an anti-obesity composition comprising an effective amount of a platelet extract as an active ingredient, and more particularly, to a pharmaceutical composition for anti-obesity or a health food containing an extract of methylene chloride at the top as an active ingredient.

Obesity is a disease caused by the imbalance of food intake and energy use, and can be accompanied by serious illnesses such as cancer, type 2 diabetes and arteriosclerosis (Kopelman, 2000). Recently, obesity, diabetes, dyslipidemia, and hypertension have been called metabolic syndrome. Despite the worldwide efforts to understand and respond to the causes of obesity, obesity is accelerating. The WTO warns that "Obesity is a disease that requires long-term transparency." Obesity is not simply a cosmetic issue, but a cause of various diseases, increasing the perception that it is a serious life-threatening disease. The World Health Organization (WHO) says 17 million people die each year from cardiovascular disease, an important risk factor for obesity, and warns that in 2015, 1.5 billion people worldwide, up by 50 percent, could suffer from obesity.

Obesity has been reported to be caused by complex factors such as genetic, social, and economic factors, as well as social diminution of exercise and failure to control energy homeostasis due to increased intake of high calorie food. Recently, the worldwide incidence of obesity associated with metabolic syndrome including type 2 diabetes, which is known to be caused by ingestion of high-calorie foods and deterioration of physical activity, is increasing. In 2025, the population with these metabolic syndrome doubles to about 300 million. Obesity is a result of the unbalance of energy intake and consumption of the human body, resulting in an increase in fat cell size due to fat accumulation and an increase in the number of adipocytes due to the differentiation of fibroblasts into adipocytes. The adipogenesis process of fibroblasts differentiates into adipogenesis, which involves liver X receptor α (LXRα), CCAAT enhancer-binding protein-α (C / EBPα), peroxisomeproliferators-activatedreceptor- γ (PPARγ) (Srebp-1c) are involved (Ntambi and and Kim, 2000; Rosen et al., 2000; Seo et al., 2004). These transcription factors are mostly expressed in adipose tissue and their activation when differentiating into adipocytes is the same as fatty acid synthase (FAS), stearoyl-CoA desaturase-1 (SCD-1), and acetyl-CoA carboxylase- (Schultz et al., 2000), which directly enhances expression of synthetic genes and increases fat accumulation in differentiated adipocytes (Joseph et al., 2002). For this reason, in order to develop an anti-obesity agent, many studies have been conducted to find natural substances that inhibit the activity of transcription factors or genes involved in adipocyte differentiation or lipogenesis (Gonzalez-Espinosa de los Monteros et al. 2011; Niwano et al., 2009).

Currently, various methods for treating obesity have been attempted. In general, the treatment of obesity includes diet therapy, exercise therapy, appetite suppressant, diuretic, diarrhea, or drug therapy using fiber to give a feeling of fullness, behavior modification therapy to correct wrong eating habits and lifestyle, Surgery for reducing the volume of fat, and fat removal surgery such as decomposing and removing fat cells using ultrasound in plastic surgery. In addition, amphetamine, reductil, thiazolidinedione, metformin, and the like, which are associated with obesity treatment, have shown various side effects. For this reason, interest in alternative approaches including the use of medicinal plants in relation to the treatment of obesity has been increasing recently, It is necessary to develop a new preventive and remedy for obesity from natural products that have been approved for stability.

<2-3> Oil Red O staining

The fat in the cells differentiated into adipocytes was stained and the degree of differentiation was measured. Cells were fixed with 10% formaldehyde for 1 hour, washed with 60% isopropanol, completely dried and stained with 60% Oil Red O for 30 minutes. After 30 minutes, the cells were rinsed 3-4 times with tertiary distilled water. After completely dried, cells with red granules in the stained cytoplasm were regarded as differentiated adipocytes, and stained Oil Red O was dissolved in 100% isopropanol Then, the absorbance at 500 nm was measured to determine the degree of differentiation of adipocytes.

<2-4> RNA extraction and real-time RT- PCR

The adipocytes were differentiated, treated with different concentrations of the drug, and extracted with QIAzol lysis reagent. Single stranded cDNA was prepared using 2 μg of RNA obtained from each experimental group as a template and using a power cDNA synthesis kit (iNtRON Biotechnology, Seongnam, Kyunggi, Korea). The expression levels of mRNA were analyzed using real-time RT-PCR (Applied Biosystems, Foster City, CA, USA) with primers specific for PPARγ, C / EBPα, aP2, adiponectin and resistin. The primers used in the experiments are shown in Table 1.

<2-5> Protein extraction and Western Blotting

3T3-L1 cells were treated with radioimmunoprecipitation assay (RIPA) buffer [50 mM Tris-HCl (pH 7.5), 0.1% sodium dodecyl sulphate (SDS), 0.1% Triton X- 1% Nonidet P-40, 0.5% sodium deoxycholate, 150 mM NaCl, 1 mM phenylmethysulphonyl fluoride]. The separated proteins (15 μg) were mixed with sample buffer (62.5 mM Tris-HCl pH 6.8, 2% SDS, 20% glycerol, 10% 2-mercaptoethanol) and allowed to react at 95 ° C for 5 minutes. After electrophoresis on 10-12% SDS-polyacrylamide (PAGE) gels, they were transferred to polyvinyl difluoride (PVDF) membrane. After blocking with 5% skim milk, several primary antibodies (PPARγ, C / EBPα, aP2, adiponectin, and resistin) were attached and reacted overnight in a refrigerated chamber. The reaction was performed with a secondary antibody for 1 hour or longer, and the target protein was identified using ECL solution (Amersham Bioscience, Piscataway, NJ, USA).

Inhibitory effect of adipocyte differentiation

The present inventors treated 4T ethyl-acetate, methylene chloride, n-butanol, and n-hexane fractions extracted from mitochondria with 3T3-L1 adipocytes The degree of inhibition of adipocyte differentiation was measured. The degree of differentiation inhibition was confirmed by Oil Red O assay and the expression level of adipocyte differentiation factor was confirmed by real-time RT-PCR and Western blot.

<4-1> 3 T3 - L1  Inhibitory effect of fat precursor cell fat accumulation

Oil Red O staining method was used to measure the inhibition of fat accumulation in the mitochondrial fraction. 3T3-L1 adipocytes were treated with each fraction to determine the degree of fat accumulation inhibition. As a result, methylene chloride and n-hexane in the fraction showed inhibitory effect on fat accumulation at 5 μg / ml (See Fig. 2).

Based on the above results, the inhibitory effect of fat accumulation at various concentrations of methylene chloride and n-hexane fractions in the mitochondrial fraction was confirmed by Oil red O staining. As a result, methylene chloride and n-hexane fractions were found to be 5 μg / ml, and it was confirmed that the inhibitory effect of the methylene chloride fraction of the topoisomerase was excellent (see FIG. 3). Therefore, subsequent experiments with fat regulators were performed with methylene chloride extract from the Hoveniae Semen cum Fructus (MHF).

<4-2> MHF Adipocyte Differentiation regulator  Gene Expression Inhibitory Effect

The adipogenesis process, which is differentiated from adipogenic precursor cells into adipocytes, is known to be induced by the gradual regulation of many adipogenic transcription factors. PPARγ and C / EBPα play the most important role in this differentiation process. These transcription factors are promoted by differentiation inducers such as hormones to differentiate adipose precursor cells into mature adipocytes. Expression of PPARγ and C / EBPα plays an important role in the expression of adipocytokines and adipogenic proteins such as adiponectin, aP2 and FAS, as well as morphological features such as intracellular lipid droplet production and cell size increase through interaction.

As a result of real-time RT-PCR, 3T3-L1 adipocytes were treated with MHF to measure the expression levels of PPARγ and C / EBPα, which are regulators of adipocyte differentiation. As a result, / EBP &lt; / RTI &gt; expression was suppressed. However, it was found that the expression of PPARy and C / EBPa could be most effectively inhibited at a concentration of 5 μg / ml (see FIG. 4).

In addition, it was also found that the expression of aP2, adiponectin, and resistin was most effectively inhibited by 5 μg / ml of MHF (see FIG. 5).
