Objectives This study was carried out to find out the anti-osteoarthritic effects of Mahwangbujaseshin- tang (Mahuangfuzixixintang ) on the monosodium iodoacetate (MIA)-induced osteoarthritis rats. Methods Osteoarthritis was induced by injecting MIA ($50{\mu}l$) into the knee joint of rats. Rats were divided into a 3 groups (n=7). The injection did not fit the normal group. A week later, after the injection of MIA, while control group took normal saline 2 ml, the extract of Mahwangbujaseshin-tang (Mahuangfuzixixintang ) (MBST) (200 mg/kg) was injected to treated group. After that, we examined hind paw weight bearing ability, functions of liver and kidney, serum TNF-$\alpha$, IL-$1{\beta}$, IL-6, $PGE_2$, $LTB_4$, TIMP-1, MMP-9 and hematology. Volume of cartilage was measured by micro CT arthrography. Injury of synovial tissue was measured by H & E, Safranin-O immunofluorescence. Results 1) DPPH and ABTS free radical scavenging activity of MBST was increased according to concentration of MBST and total phenolic contents were in high level. 2) In RAW 264.7 cells, ROS production was significantly decreased in MBST (at 10, $100{\mu}g/ml$) and NO was also decreased but meaningless in MBST (at $100{\mu}g/ml$). 3) In RAW 264.7 cells, IL-6 production was significantly decreased in MBST (at $100{\mu}g/ml$) and TNF-$\alpha$ and IL-$1{\beta}$ production were also decreased but meaningless in MBST (at $100{\mu}g/ml$). 4) In hind legs weight-bearing measurement, level of weight-bearing was increased. 5) Functions of liver and kidney were not affected. 6) TNF-$\alpha$, IL-$1{\beta}$, IL-6, $PGE_2$, $LTB_4$, MMP-9 and TIMP-1 production were significantly decreased. 7) In hematology, the levels of neutrophils, monocytes were significantly decreased and the levels of white blood cells, lymphocytes were also decreased but meaningless. 8) In micro CT-arthrography, cartilage volume was significantly increased. 9) Histopathologically, injury on cartilage and synovial membrane of MBST group was decreased. Conclusions Based on all results mentioned above, Mahwangbujaseshin-tang (Mahuangfuzixixintang) is believed to be meaningful for suppressing the progress of osteoarthritis. And it is related to inhibiting the activity of inflammatory cytokine and injury of volume in cartilage.

천궁(C. officinale)은 예로부터 민간처방 약재로 사용되었으며, 항염증, 항산화, 항암 및 신생혈관억제 등의 효능을 가지는 것으로 알려져 있다. 하지만 혈구암세포에서 apoptosis 유발과 관련된 분자생물학적 기전에 대해서는 명확히 밝혀져 있지 않다. 본 연구에서는 인체 혈구암세포인 U937 세포에서 천궁의 열수, 에탄올 및 메탄올 추출물(WECO, EECO 및 MECO)이 유발하는 항암효과 및 항암기전을 조사하였다. 먼저 WECO, EECO 및 MECO가 유발하는 증식억제 정도를 조사한 결과 EECO가 가장 뛰어난 효능을 가진다는 것을 알 수 있었으며, 이러한 현상이 apoptosis 유발에 의한 것임을 annexin-V 염색, apoptotic body 형성, DNA 단편화 및 MMP 소실 등을 통하여 확인하였다. EECO 처리에 의한 apoptosis 유발에는 DR4의 발현 증가와 함께 cIAP-1, Bcl-2 및 total Bid의 발현감소가 관여하였으며, caspases-3, -8 및 -9의 활성화와 함께 caspases-3의 기질 단백질인 PARP, β-catenin 및 PLC γ1의 단편화도 관찰되었다. 또한 EECO는 AMPK signaling pathway를 활성화시키는 것으로 나타났으며, AMPK 억제제인 compound C를 이용하여 AMPK의 활성을 억제하였을 경우 EECO에 의하여 유발되었던 apoptosis가 현저하게 감소되는 것으로 나타났다. 이상의 결과를 살펴볼 때 인체 혈구암세포인 U937 세포에서 EECO에 의하여 유발되는 apoptosis는 AMPK가 중요한 조절자로서 작용하는 것으로 생각된다.

Lip and oral cavity cancer, which can occur in any part of the mouth, is the 11th most common type of cancer worldwide. The major obstacles to patients' survival are the poor prognosis, lack of specific biomarkers, and expensive therapeutic alternatives. This study aimed to identify the main genes and pathways associated with lip and oral cavity carcinoma using network analysis and to analyze its molecular mechanism and prognostic significance further. In this study, 472 genes causing lip and oral cavity carcinoma were retrieved from the DisGeNET database. A protein-protein interaction network was developed for network analysis using the STRING database. VEGFA, IL6, MAPK3, INS, TNF, MAPK8, MMP9, CXCL8, EGF, and PTGS2 were recognized as network hub genes using the maximum clique centrality algorithm available in cytoHubba, and nine potential drug candidates (ranibizumab, siltuximab, sulindac, pomalidomide, dexrazoxane, endostatin, pamidronic acid, cetuximab, and apricoxib) for lip and oral cavity cancer were identified from the DGIdb database. Gene enrichment analysis was also performed to identify the gene ontology categorization of cellular components, biological processes, molecular functions, and biological pathways. The genes identified in this study could furnish a new understanding of the underlying molecular mechanisms of carcinogenesis and provide more reliable biomarkers for early diagnosis, prognostication, and treatment of lip and oral cavity cancer.

본 연구는 포도수확 후 버려지는 가지를 이용한 포도전정가지 추출물(Grape Pruning Stem Extracts, GPSE)에 함유된 polyphenol류 중 항산화, 항염증, 항암 등의 효과가 있다고 알려진 rutin, procyanidin B3, quercetin, kaempferol의 함량을 분석하고, UVB로 유도된 HR-1 mice의 손상된 피부에 대한 교원섬유, 탄력섬유 파괴억제 효과를 측정하여 기능성 화장품 소재로서의 응용 가능성을 확인하고자 하였다. 포도전정가지에서 polyphenol 성분을 80% EtOH로 추출하고 여과하여 농축한 후, 동결건조하여 $-20^{\circ}C$에 보관하면서 사용하였다. GPSE의 유효성분 함량은 HPLC를 사용하여 분석하였다. 피부손상을 유도하기 위해 UVB를 HR-1 hairless mice에 조사하였고, 손상된 피부에 교원섬유 파괴억제 효과를 보기 위해 Masson's trichrome stain, 탄력섬유 파괴 억제 효과를 보기 위해 Verhoeff's elastic fiber stain, MMP-9 단백 발현을 보기 위해 면역조직화학적 염색을 실시하였다. 본 연구에 사용된 포도전정가지 시료 53 kg에서 EtOH 분획 추출물 2.34 kg을 추출하여 4.42%의 수율 결과를 얻었다. 유효성분 분석결과, procyanidin B3, 0.28 mg/g, rutin 12.81 mg/g, quercetin 0.51 mg/g 및 kaempferol 8.24 mg/g로 나타났다. GPSE와 serum base를 혼합 도포한 그룹에서 UVB에 의한 교원섬유와 탄력섬유를 분해하는 MMP-9 단백발현 결과, 대조군 대비 평균 약 90% 감소 억제하는 효과를 볼 수 있었다. 교원섬유 파괴억제 효과는 모든 농도에서 평균 24%의 억제율과, GPSE와 serum base의 혼합물 농도 2,000 mg/kg 에서 43%로 가장 우수한 교원섬유 파괴억제효과가 나타났으며, 탄력섬유파괴 억제 효과는 모든 농도에서 평균 12%의 억제율과 GPSE와 serum base의 혼합물 농도 1,000 mg/kg에서 35%로 가장 우수한 탄력섬유 파괴 억제 효과가 있는 것으로 나타났다. 이 결과는 GPSE가 진피층의 세포 외 기질에 UVB 조사에 의해 파괴되는 교원섬유, 탄력섬유의 파괴를 억제하는 작용을 한다는 것을 알 수 있었다. 이상의 결과로 포도전정가지로부터 rutin, kaempferol, quercetin, procyanidin B3 등의 폴리페놀성 화합물이 화장품 기초 원료인 serum base에 함유토록 제조된 GPSE 는 교원섬유 파괴 억제, 탄력섬유파괴 억제효과 및 피부손상 기능개선 효과의 결과를 얻을 수 있었다. 본 연구의 의의는 지역포도농가에서 수확 후 버려지는 포도전정가지에서 폴리페놀류와 같은 유효성분을 확보하여 화장품 원료로서의 활용 가치가 높을 것으로 기대된다.

Objectives : We compared the inhibitory effects of herb-combined remedies, which were recorded on "Yooam" prescription of Dongeuibogam, on cell migration and invasion, two critical cellular processes that are often deregulated during metastasis, in B16F10 melanoma cells. For this purpose, water extracts of Sipyukmiryukieum (SYMRKU), Danjacheongpitang (DJCPT), Cheongganhaeultang (CGHUT) and Jipaesan (JPS) were used. Methods : Cytotoxicity was assessed by an MTT assay. Wound healing and matrigel transwell assays were used to examine on B16F10 cell migration and invasion. The levels of mRNA and protein expression of matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinases (TIMPs) were analyzed by RT-PCR and Western blotting. Results : Our data showed that DJCPT showed the strongest inhibitory effect among the four prescriptions in inhibiting cell motility of B16F10 melanoma cells within the concentration range that was not cytotoxic. The inhibitory potential of colony formation was higher in DJCPT and SYMRKU compared to the other two types of prescriptions, and the inhibitory effect of invasiveness is shown in order of DJCPT, SYMRKU, CGHUT and JPS. DJCPT, and SYMRKU strongly inhibited the activity and expression of MMP-2 and MMP-9, which are important mediators in cancer invasion, compared to CGHUT and JPS, and the increased expression of TIMP-1 and TIMP-2 was also more effective in these two prescriptions. In conclusion, DJCPT is expected to exhibit the most potent blocking effect on migration and invasion among four herb-combined remedies compared in B16F10 melanoma cells. Conclusion : Overall, the results of this study will be used as an important source to validate these prescriptions in animal models and to understand the mechanism of action of herbal remedies recorded in Dongeuibogam.

We evaluated the protective effects of cricket methanol extract (CME) on ultra-violet B (UVB)-induced photoaging in human skin fibroblasts. The fibroblast cells were treated with 10, 50, and 100 ㎍/mL of CME for 24 h, and then exposed to UVB (30 mJ/㎠). CME showed a dose-dependent cytoprotective effect without any observable cytotoxicity. CME reduced UVB-induced production of reactive oxygen species (ROS) by 34.4, 34.9, 40.6% at concentrations of 10, 50, 100 ㎍/mL respectively. CME inhibited the release of matrix metalloproteinase (MMP) 1 and 3. Furthermore, CME also reduced UVB-induced collagen degradation in the fibroblast cells. Taken together, our data suggests that CME has a significant protective effect on UVB-induced photoaging of the skin. This benefit occurs through multiple mechanisms. The results also suggest a potential role for CME as an ingredient in anti-photoaging cosmetic products in the future.

Background: CM1 (centrocyte/-blast marker 1) was defined by a mAb against concavabalin-A (ConA) activated PBMC. It is expressed in germinal center of human tonsil and on the surface of activated PBMC as well as cancer cells. Recently, increased productions of pro-inflammatory mediators were detected from activated PBMC by CM1 ligation. Methods: However, there is a limitation to explain the exact role of CM1 on inflammation and its related mechanisms, since the identity of CM1 is still not clarified. In our previous study, we have already confirmed that soluble form of CM1 was produced by Raji. Therefore, we performed Q-TOF analysis after immunoprecipitation of concentrated Raji culture supernatant using anti-CM1 mAbs. Results: As a result, we found that CM1 is identical to enolase-1(ENO1), a glycolytic enzyme, and we confirmed that results by silencing ENO1 using siRNA. It was also confirmed through competition assay between anti-CM1 and anti-ENO1 mAbs. Finally, we investigated the possible role of CM1 in inflammatory response and cancer. The ligation of CM1 on Raji cells with anti-CM1 mAbs induces the extensive production of prostaglandin $E_2(PGE_2)$. In addition, the increased activity of matrix metalloproteinase (MMP)-2/9 was shown in NCI-N87, stomach cancer cell line by CM1 stimulation. Conclusion: CM1 is identical to ENO1 and it might be an important role in the regulation of inflammatory responses.
