  • Objective : This study was designed to evaluate the synergistic effect on cytotoxicity of combination with adriamycin and Palginhonhapwhajucwhan, a traditional prescription for cancer treatment in oriental medicine, in Chang, HL-60, Hep-3B and Alexander cells. Methods : We observed cell viability in Chang, HL-60, Hep-3B, and Alexander cells by crystal violet staining. Those cells were treated with various concentrations of adriamycin alone, Palginhonhapwhajucwhan alone and combination of two medications for 10 hr. On condition of $0.5{\mu}l/ml$ adriamycin alone, $15.6{\mu}l/ml$ Paljintanghapwhajucwhan alone and combination of two medications, at first, we observed colony forming of Chang and HL-60 cells. Second, we observed DNA fragmentation by agarose electrophoresis in Chang, HL-60, Hep-38 and Alexander cells. Third, we measured the catalytic activation of caspase-1, 2, 3, 6, 8, and 9 protease in Chang cells and caspase-3 protease in Chang, HL-60, Hep-3B and Alexander cells by using fluorogenic substrate. Finally, we isolated mRNA of Fas in Chang, HL-60, Hep-38 and Alexander cells and observed that Fas gene was amplified by RT-PCR Results : 1. The combination of adriamycin and Palginhonhapwhajucwhan synergistically augmented the cytotoxicity of Chang and HL-60 cells whereas did not in Hep-38 and Alexander cells. 2. Cotreatment of two drugs also markedly inhibited the colony forming ability both in Chang and HL-60 cells. 3. The cytotoxicity of these medicatons was revealed as apoptosis characterized by high molecular wight DNA fragmentaton. 4. The apoptotic cytotoxicity was mediated by activation of caspase-3 protease in Chang cells. 5. Synergistic increase in apoptotic cytotoxicity by combination of two medications was dependent on the expression of Fas in cancer cells. Conclusions : Combination of adriamycin and Palginhonhapwhajucwhan significantly augmented apoptotic cytotoxicity of Fas-positive cells such as Chang and HL-60 cells via acticaton of apoptosis signaling pathway.

  • 제주조릿대 잎은 항염, 해열 및 이뇨작용을 가지고 있어 위궤양, 목마름 및 토혈 치료를 위한 민간의약으로 사용되어 왔다. 본 저자들은 제주조리대 잎에서 분리한 피토케미칼 풍부 추출물(PRE)과 그 에틸아세테이트 분획물(EPRE)은 여러 위암 세포주에서 세포사멸을 유도하는 항암 효과가 있다고 보고한 바 있다. 본 연구는 EPRE의 세포사멸 유도 기전에 관여하는 분자표적들을 탐색하기 위하여 EPRE을 처리한 SNU-16 세포에서 mRNA와 microRNA (miRNA)의 프로파일 변화를 분석하였다. RNA sequencing 분석을 통해 총 2,875개의 차등적으로 발현되는 유전자들(DEGs)을 동정하였다. 유전자 온톨로지(GO)와 KEGG 경로 분석 결과, EPRE는 세포사멸, 유사 분열-활성화 단백질 키나제(MAPK) 및 염증 반응, 종양 괴사 인자(TNF) 신호 전달 및 암 경로에 관여하는 유전자들의 발현을 조절하는 것으로 나타났다. 단백질-단백질 상호 작용(PPI) 네트워크 분석으로 세포사멸 및 세포죽음과 관련된 유전자들 간의 상호작용들을 확인할 수 있었다. 그리고, miRNA sequencing 분석을 통해 총 27개의 차별적으로 발현되는 miRNAs (DEMs)를 동정하였다. GO와 KEGG 경로 분석 결과, EPRE는 세포주기, 세포사멸 및 tropomyosin-receptor-kinase (TRK) 수용체 신호 전달, 성장인자-β(TGF-β), 핵인자 κB (NF-κB) 및 암 경로에 관여하는 miRNAs의 발현을 조정하였다. 본 연구결과는 EPRE의 항암 효과의 근본적인 메커니즘에 대한 통찰력을 제공한다.

  • Many proteins with poor transduction efficiency were reported to be delivered to cells by fusion with protein transduction domains (PTDs). In this study, we investigated the effect of levosulpiride on the transduction of PEP-1 ribosomal protein S3 (PEP-1-rpS3), and examined its influence on the stimulation of the therapeutic properties of PEP-1-rpS3. PEP-1-rpS3 transduction into HaCaT human keratinocytes and mouse skin was stimulated by levosulpiride in a manner that did not directly affect the cell viability. Following 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced inflammation in mice, levosulpiride alone was ineffective in reducing TPA-induced edema and in inhibiting the elevated productions of inflammatory mediators and cytokines, such as cyclooxygenase-2, inducible nitric oxide synthase, interleukin-6 and -1${\beta}$, and tumor necrosis factor-${\alpha}$. Anti-inflammatory activity by PEP-1-rpS3 + levosulpiride was significantly more potent than by PEP-1-rpS3 alone. These results suggest that levosulpiride may be useful for enhancing the therapeutic effect of PEP-1-rpS3 against various inflammatory diseases.

  • Background: Korean Red Ginseng (KRG) is a well-known natural product with anticarcinogenic and antioxidant effects. We evaluated the antifatigue effect of KRG in patients with nonalcoholic fatty liver disease (NAFLD). Methods: Eighty patients with NAFLD were prospectively randomized to receive 3 wk of KRG or placebo in addition to counseling on healthy eating and regular exercise. Liver function test, proinflammatory cytokines, adiponectin, antioxidant activity, and fatigue score were measured and compared according to the body mass index between the KRG and placebo groups. Results: The liver function tests were significantly improved after 3 wk of treatment in both groups. The mean levels (at baseline and after treatment) of tumor necrosis factor-${\alpha}$ were $108.0pg/mL{\pm}54.8pg/mL$ and $92.7pg/mL{\pm}39.0pg/mL$ (p = 0.018) in the KRG group and $123.1pg/mL{\pm}42.1pg/mL$ and $127.5pg/mL{\pm}62.2pg/mL$ (p = 0.694) in the placebo group, respectively. There was a significant difference in change of adiponectin levels between the KRG ($7,751.2pg/mL{\pm}3,108.1pg/mL$ and $8,197.3pg/mL{\pm}2,714.5pg/mL$) and placebo groups ($7,711.6pg/mL{\pm}3,041.3pg/mL$ and $7,286.1pg/mL{\pm}5,188.7pg/mL$, p = 0.027). In patients with overweight, the fatigue score was significantly decreased in the KRG group ($35.0{\pm}13.2$ and $24.5{\pm}8.9$, p = 0.019). Conclusion: Our results show that KRG might be effective in reducing proinflammatory cytokine and fatigue in overweight patients with NAFLD, in addition to improvements in adiponectin levels.

  • Objectives: The aim of this study was to observe the reduction of lipid accumulation by treatment with Akkermansia muciniphila extract on 3T3-L1 adipocytes. Methods: After treating pasteurized Akk. muciniphila strains in HT-29 colorectal cancer cell, the relative expression of interleukin (IL)-8, tumor necrosis factor-α, IL-6, and IL-1β mRNA was analyzed by real time polymerase chain reaction, respectively. 27 strains of Akk. muciniphila which have anti-inflammatory effects were selected. 3T3-L1 pre-adipocytes were treated with Akk. muciniphila for 24 hr and then measured the toxicity using water soluble tetrazolium salt assay. The cells were incubated for 4 days and then differentiated into adipocytes using the medium including adipogenic reagents for 10 days. The Akk. muciniphila was treated when the medium was exchanged for differentiation medium at 4th day and insulin medium at 6th day. To observe the lipid accumulation, the cells were stained with Oil red O dye and were measured using a spectrophotometer. Results: In the cytotoxicity test, the cell viability of 3T3-L1 pre-adipocytes was significantly increased compared to the control group which untreated with Akk. muciniphila, and there was no cytotoxicity of Akk. muciniphila at 1×107 CFU/mL. The results on Oil red O staining and absorbance measurements were showed a significant decrease in lipid accumulation in the group which was treated with Akk. muciniphila compared to the control group. Conclusions: In our results, Akk. muciniphila has the inhibitory effect of lipid accumulation in 3T3-L1 adipocytes. This suggests that Akk. muciniphila could be help to improve obesity.

  • 녹차(GT) 추출물의 효과를 인간 유방암 유래 세포인 MCF-7 세포를 사용하여 조사 하였다. GT추출물의 세포 독성 효과를 MTT 방법을 사용하여 관찰한 결과, MCF-7 세포는 현저한 세포 독성 효과를 보였고, 이 독성 효과는 GT추출물 농도 의존적으로 증가하였다. p53과 관련 단백질인 p21/cip1과 CDK2의 연관성을 조사하기 위해 GT추출물 처리 후 웨스턴 분석법을 통해 이들 단백질의 발현을 조사하였다. GT추출물 처리 후, MCF-7 세포에서 p53 단백질의 양은 농도에 따라 현저하게 증가 하였다. p21/cip1 단백질의 발현은 낮은 농도의 GT추출물에서 증가되며, 고농도에서도 감소하지 않았다. 그러나 CDK2의 단백질의 양은 높은 농도의 GT추출물에서 CDK2 발현의 급격한 감소가 관찰되었다. 이 결과는 GT추출물의 처리는 MCF-7 세포에서 p53와 p21/cip1를 증가시켜, 그 결과로 활성화 된 p21/cip1는 CDK2의 발현을 억제 함을 나타내고 있다. GT추출물이 MCF-7 세포의 세포주기에 어떤 영향을 미치는지 확인하기 위하여 FACS 분석으로 관찰한 결과, MCF-7 세포에서 세포주기의 G1 단계가 점차 증가하는 결과를 보였다. 이 결과는 GT추출물의 유방암 세포에서의 항암 효과는 세포주기의 G1 단계에서 MCF-7 세포를 정지시키는 p53에 의해 조절된다는 사실을 명확하게 보여 주고 있다.

  • There have been no published studies concerning the anti-inflammatory effects of corn silk on colon cancer cells. Thus, this study was conducted to investigate the effect of corn silk extract containing high levels of maysin on inflammation and its mechanism of action in colon cancer cells. SW 480 human colon cancer cells were treated with $1{\mu}g/mL$ of lipopolysaccharide (LPS) to induce inflammation, and next they were treated with different concentrations of corn silk extract (0, 5, 10 and $15{\mu}g/mL$). The concentrations of nitric oxide (NO) were determined. The mRNA expressions of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), tumor necrosis factor ${\alpha}$ ($TNF-{\alpha}$), interleukin-1beta ($IL-1{\beta}$) and interleukin-6 (IL-6), were determined. Western blot analysis was performed to determine the protein expressions of nuclear factor-kappa B ($NF-{\kappa}B$) and mitogen-activated protein kinases, and the latter consists of extracellular signal-related kinase (ERK), c-jun NH2-terminal kinase (JNK) and p38 MAP kinase (p38). The concentration of NO and the mRNA expression of iNOS were significantly and dose-dependently decreased in the corn silk-treated groups (P<0.05). The mRNA expression of $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 were significantly increased in the LPS-treated group (P<0.05), but these expressions were significantly and dose-dependently decreased in the corn silk treated groups (P<0.05). The protein expressions of $NF-{\kappa}B$ (in a dose-dependent fashion), ERK (at 10 and $15{\mu}g/mL$), JNK (at $15{\mu}g/mL$) and p38 (at 10 and $15{\mu}g/mL$) were significantly decreased with corn silk treatments (P<0.05). In conclusion, corn silk extract containing high levels of maysin seems to inhibit the LPS-induced inflammatory responses in SW480 colon cancer cells via the $NF-{\kappa}B$ pathway.
