  • Abilities of Korean black raspberry (KBR) wine to induce differentiation of 3T3 L1 adipocytes and express HepG2 cardiovascular disease-related genes were determined and compared with those of red wine. Red wine attenuated the differentiation of adipocytes faster than KBR wine and control. KBR wine decreased cholesterol concentration in HepG2 cells at a similar level to that of red wine, resulting in similar degrees of suppression in apolipoprotein B100, and enhancement in LDL receptor and 3-hydroxy-3-methylglutaryl coenzyme A reductase mRNA levels.

  • Background: Inorganic arsenic is a human carcinogen that can target the liver, but its carcinogenic mechanisms are still unknown. Inorganic arsenic induces a spectrum of tumors including hepatocellular carcinoma in mice. Methods: Pregnant C3H mice were supplied with drinking water containing 50 ppm sodium arsenite during their pregnancy. The protein expression profile in the liver of 0.5-day-old. male offsprings exposed transplacentally to sodium arsenite was analyzed using protein 2D gel electrophoresis followed by mass spectrometry (MALDI-TOF). Results: Expression of proteins such as hydroxymethylglutaryl-CoA synthase mitochondrial precursor (HMG-CoA synthase), ${\beta}$-actin (cytoplasmic 1) and apolipoprotein A-IV precursor (Apo-AIV) were induced in mouse liver by sodium arsenite, while uricase (urate oxidase), guanine nucleotidebinding protein beta subunit 2-like 1 (RACK1) and fructose-bisphosphate aldolase B (Aldolase 2) were down-regulated. Summary: Expression of proteins that have been implicated in carcinogenesis, such as HMG-CoA, ${\beta}$-actin, and RACK1, was regulated in the liver of mice transplacentally exposed to inorganic arsenic.

  • Myofibrillogenesis regulator-1 (MR-1) is a novel protein involved in cellular proliferation, migration, inflammatory reaction and signal transduction. However, little information is available on the relationship between MR-1 expression and the progression of atherosclerosis. Here we report atheroprotective effects of silencing MR-1 in a model of Ang II-accelerated atherosclerosis, characterized by suppression focal adhesion kinase (FAK) and nuclear factor kappaB ($NF-{\kappa}B$) signaling pathway, and atherosclerotic lesion macrophage content. In this model, administration of the siRNA-MR-1 substantially attenuated Ang II-accelerated atherosclerosis with stabilization of atherosclerotic plaques and inhibited FAK, Akt, mammalian target of rapamycin (mTOR) and NF-kB activation, which was associated with suppression of inflammatory factor and atherogenic gene expression in the artery. In vitro studies demonstrated similar changes in Ang II-treated vascular smooth muscle cells (VSMCs) and macrophages: siRNA-MR-1 inhibited the expression levels of proinflammatory factor. These studies uncover crucial proinflammatory mechanisms of Ang II and highlight actions of silencing MR-1 to inhibit Ang II signaling, which is atheroprotective.

  • Alzheimer's disease(AD) is a progressive neurodegenerative disease, which is pathologically characterized by neuritic plaques and neurofibrillary tangles associated with the acetylcholinesterase, apolipoprotein E and butylcholinesterase, and by mutations in the presenilin genes PS1 and PS2, and amyloid precursor proteins (APPs) overexpression. The present research is to examine the inhibitory effect of KGBH on PS1, PS2 and APPs overexpression detected by Western blotting. To verify the Effects of KGBH on cognitive deficits further, we tested it on the scopolamine(1mg/kg)-induced amnesia model of the mice using the Morris water maze tests, and there were ameliorative effects on memory impairment as a protection against scopolamine. KGBH only partially blocked the increase in blood serum level of acetylcholinesterase and Uric acid induced by scopolamine, where as blood glucose level was shown to attenuate the amnesia induced by scopolamine and inreased extracellular serum level. In conclusion, studies of KGBH that has been known as anti-choline and inhibitory ablilities of APPs overexpression, could also be used further as a important research data for a preventive and promising symptomatic treatment for Alzheimer's disease.

  • 대두는 여러 종류의 파이토케미컬을 함유하고 있으며 이에 의한 항산화, 항염증, 항비만 효능 등이 있음이 잘 알려져 있다. 대두 부산물 성분의 비만억제효능을 확인하기 위하여 Oil-Red O 염색법과 정량 PCR을 통하여 지방세포분화억제 및 지방생성억제 효능을 분석하였다. 분화유도물질인 isobutylmethylanthine (IBMX), dexamathasone 및 insulin 처리에 따른 지방세포 분화유도와 함께 대두부산물-침지수, 순물, 두유-의 처리는 세포손상 없이 지방세포분화 연관 유전자-PPAR${\gamma}$, Fabp4, Scd1, adipsin, apolipoprotein (APOE), adiponectin (ADIPOQ)-의 발현을 감소시키는 효능을 보였다. 또한 대두에서 잘 알려진 isoflavone -daidzein과 genistein- 분석을 통하여 대두 부산물에 포함된 두 종류의 isoflavone의 함량을 확인하였다. 결과적으로 대두부산물에는 지방세포분화유도 유전자의 발현억제를 통한 전지방세포의 분화 및 지방세포의 지방생성을 억제하고 있음을 확인하였다. 따라서 두부생산 시 발생하는 대두부산물은 지방세포분화 억제 효능을 바탕으로 이를 이용하는 건강기능 식품제조에 활용될 수 있을 것으로 판단된다.

  • Objectives : To observe the changes in the serum proteins after intravenous injection of cultivated wild ginseng pharmacopuncture. Methods : Blood was collected before and after the administration of cultivated wild ginseng pharmacopuncture and only the serum was taken. Then differences in the spots on the scanned image after carrying out 2-Dimensional electrophoresis were located and conducted mass analysis and protein identification. Results : Following results were obtained from the comparative analysis of serum proteins before and after the administration of cultivated wild ginseng pharmacopuncture. 1. 28 spots were identified before and after the administration. 2. In confirming manifestation degree, spots with more than two-times increase were 204, 1302, 2205, 3105, 7104, 8006, spots with more than one-time increase were 1101, 1505, 2013, 2403, 3009, 3010, 4002, 4009, 6704, 8101, and spots with decrease were 205, 801, 803, 3205, 5202, 6105, 6106, 7103, 9001, 9003. 3. After conducting protein identification, proteins 205, 804, 1302, 4009, 6105, 6106 are unidentified yet, and 1l01 is unnamed protein. Protein 204 is identified as complement receptor CR2-C3d, 801 as YAPl protein, 803 as antitrypsin polymer, 1505 as PRO0684, 2013 and 3010 as proapolipoprotein, 2205 as USP48, 2403 as vitamin D binding protein, 3009 as complement component 4A preprotein, 3105 as immunoglobulin lambda chain, 3205 as transthyretin, 4002 as Ras-related protein Ral-A, 4204 as beta actin, 5202 and 7104 as apolipoprotein Ll, 6704 as alpha 2 macroglobulin precursor, 7103 as complement component 3 precursor, 8006 as testis-specific protein Y, 8101 as transferrin, 9001 as (Alpha-Oxy, Beta-(Cl12g)deoxy) T-State Human Hemoglobin, and 9003 as human hemoglobin. 4. Immune protein CR2-C3d(204), which acts against microbes and pathogenic organisms, was increased by more than two-times after the administration of pharmacopuncture. 5. Antitrypsin(803), which is secreted with inflammatory response in the lungs, was reduced after the administration of pharmacopuncture. 6. Proapolipoprotein(2013, 3010) and apolipoprotein(7104), key components of the HDL-cholesterol which plays an important role in preventing arteriosclerosis, were increased after the administration of pharmacopuncture. 7. Vitamin D binding protein(DBP, 2403), protecting the lung at the time of inflammatory response, was increased after the administration of pharmacopuncture. 8. Transthyretin(TTR, 3205), which is the main protein causing familial amyloid polyneuropathy(FAP), was decreased after the administration of pharmacopuncture. 9. Ras-related protein Ral-A(4002) that controls phospholipid metabolism, cytoskeletal formation, and membrane traffic, was increased after the administration of pharmacopuncture. 10. Testis-specific protein Y(8006), which takes part in determination of the gender, was increased by more than two-times after the administration of pharmacopuncture. 11. Transferrin(8101), which balances the iron level in the body, was increased after the administration of pharmacopuncture. Conclusion : Above results support the notion that intravenous injection of cultivated wild ginseng pharmacopuncture induce changes in serum proteins and this research can be a pioneer work in finding biomarkers.
