  • For the evaluation of anti-tumor activity of Korean Oldenlandia Herb (KOH) and Radix (KOR), our experiment was performed with methanol extracts of KOH and KOR. They did not shown any cytotoxicity against HT1080 cell lines. However, they effectively showed anti-metastatic activity through inhibition of the adhesion of HT1080 cells to gelatin, downregulated the expression of MMP2 and uPA and upregulated the expression of TIMP2. They also inhibited tube formation of HUVECs induced by bFGF. However, they did not affect DNA topoisomerase I activity. Simiarly, the T/Cs % in KOH and KOR treated mice were increased 134.9% and 171 %, respectively at 2500 mg/kg. These results suggest that KOH and KOR exert anti-tumor activity via anti-metastatic and anti-angiogenic activities. The further study for isolation of effective compounds and its exact mechanism and comparative study with Chinese Oldenlandia Herba will be required.

  • Purpose: Tumor necrosis factor (TNF)-${\alpha}$ is thought to contribute to pulmonary hypertension. We aimed to investigate the effect of infliximab (TNF-${\alpha}$ antagonist) treatment on pathologic findings and gene expression in a monocrotaline-induced pulmonary hypertension rat model. Methods: Six-week-old male Sprague-Dawley rats were allocated to 3 groups: control (C), single subcutaneous injection of normal saline (0.1 mL/kg); monocrotaline (M), single subcutaneous injection of monocrotaline (60 mg/kg); and monocrotaline + infliximab (M+I), single subcutaneous injection of monocrotaline plus single subcutaneous injection of infliximab (5 mg/kg). The rats were sacrificed after 1, 5, 7, 14, or 28 days. We examined changes in pathology and gene expression levels of TNF-${\alpha}$, endothelin-1 (ET-1), endothelin receptor A (ERA), endothelial nitric oxide synthase (eNOS), matrix metalloproteinase (MMP) 2, and tissue inhibitor of matrix metalloproteinase (TIMP). Results: The increase in medial wall thickness of the pulmonary arteriole in the M+I group was significantly lower than that in the M group on day 7 after infliximab treatment (P<0.05). The number of intraacinar muscular arteries in the M+I group was lower than that in the M group on days 14 and 28 (P<0.05). Expression levels of TNF-${\alpha}$, ET-1, ERA, and MMP2 were significantly lower in the M+I group than in the M group on day 5, whereas eNOS and TIMP expressions were late in the M group (day 28). Conclusion: Infliximab administration induced early changes in pathological findings and expression levels of TNF-${\alpha}$, and MMP2 in a monocrotaline-induced pulmonary hypertension rat model.

  • Objective: The aim of this study was to investigate the clinical significance of annexin a1 (ANXA1) and provide molecular evidence to support that decreased ANXA1 expression could enhance cancer migration and invasion in pancreatic ductal adenocarcinoma (PDAC). Materials and Methods: Immunohistochemistry of a tissue microarray with 162 surgically resected PDAC specimens was performed to examine the expression of ANXA1. We also investigated the relationship between ANXA1 expression and clinicopathological factors and prognosis of PDAC patients. We further studied the role of ANXA1 in PDAC cell proliferation, migration and invasion by cell proliferation assay, migration assay and matrigel invasion assay with reduced ANXA1 expression by RNAi. Western blotting was used to detect matrix metalloproteinase-9 (MMP-9), and tissue inhibitor of metalloproteinase-1 (TIMP-1) expression. We also detected MMP-9 enzyme activity by gelatin zymography. Results: Decreased expression of ANXA1 was significantly associated with poor differentiation, lymph node metastasis and advanced TNM stage of PDAC patients (p<0.05). Moreover, decreased expression of ANXA1 was correlated with poor survival (p<0.05). Furthermore, we found that ANXA1 knockdown inhibited cell proliferation, induced G1 phase cell cycle arrest, increased PDAC cell migration and invasion capacity compared with controls. In addition, Western blotting showed that ANXA1 knockdown increased the MMP-9 protein level and decreased TIMP-1 expression. Gelatin zymography showed that MMP-9 enzyme activity was also elevated. Conclusions: Negative ANXA1 expression is a most unfavorable prognostic factor for PDAC patients. ANXA1 knockdown inhibits cell proliferation by inducing G1 phase cell cycle arrest and increases migration and invasion of PDAC cells through up-regulating MMP-9 expression and activity, implying that ANXA1 may serve as a promising prognostic biomarker and therapeutic target for PDAC.

  • GST, an extract from 16 herbs, has been formulated and prescribed for the treatment of human rheumatoid arthritis(hRA) for many years. The present study was done to investigate whether GST has suppressive effects on activation of fibroblast-like sinoviocytes isolated from an RA patient. In tumor necrosis factor-a(TNF-a)/interleukin-1b(IL-1b) treated human sinoviocytes, The mRNA expression of molecular indicators related to pathologic changes of the sinoviocytes were examined using quantitative real-time PCR. The treatment of GST($100\;{\mu}g/ml$) suppressed the expression of proinflammatory cytokines and chemokines such as TNF-a, IL-1b, IL-6 and IL-8 compared with the control. The mRNA level of intracellular adhesion molecule-1(ICAM-1) which is known to increase in the activated sinoviocytes of RA patients, was slightly decreased by GST. The expression of NOS-II was considerably reduced, which was accompanied by a decrease in the production of nitric oxide(NO). In addition, GST considerably increased the mRNA levels of tissue inhibitors of matrix metalloproteinase-1(TIMP-1), while those of matrix metalloproteinase-3(MMP-3) were decreased. Taken together, these data suggested that GST might suppress the activation of sinoviocytes in hRA.

  • A mutation of UNCL, an inner nuclear membrane RNAbinding protein, has been found to eliminate mechanotransduction in Drosophila. UNCL is expressed in human periodontal tissue including in periodontal ligament (PDL) fibroblasts. However, it is unclear how a mechanical stimulus is translated into cellular responses in PDL fibroblasts. The aim of this study was to evaluate the effect of UNCl on mechanical stress related genes in PDL fibroblasts in response to mechanical stress. The mRNA of TGF-$\beta$, COX-2, and MMP-2 was up-regulated after UNCL inactivation in PDL fibroblasts under the compression force. Under the tensile force, inactivation of UNCL decreased the expression of Biglycan, RANKL, MMP-2, and TIMP-2 mRNAs while it increased the expression of TIMP-1. p38-MAPK was expressed in PDL fibroblasts under compression forces whereas phospho-ERK1/2, p65-NFkB, and c-fos were expressed under tension forces. The expression and phosphorylation of the mechanical stress related genes, kinases, and transcription factors were changed according to the types of stress. Furthermore, most of them were regulated by the inactivation of UNCL. This suggests that UNCL is involved in the regulation of mechanical stress related genes through the signaling pathway in PDL fibroblasts.

  • Objectives This study was performed to investigate the effects of Saengkanggamchotang (SKT) on the monosodium iodoacetate (MIA) induced osteoarthritis in rats. Methods Osteoarthritis was induced by injection of MIA (50 ul, 60 mg/ml) into knee joints of rats. Rats are divided into a total of 4 groups (normal, control, positive comparison group, SKT treated group, each n=6). Normal group are not treated at all without inducing osteoarthritis whereas control group were induced for osteoarthritis by MIA and oral medicated with 20 ml of distilled water per day. Positive comparison group was injected with MIA and after 7 days, that was taken indomethacin (30 mg/kg/mouse). SKT treated group was injected with MIA and after 7 days that was taken SKT (30 mg/kg/mouse). Positive comparison group and SKT treated group were oral medicated for each substance a total of 4 weeks with one time per day. After experiments (from 1 week after injection of papain to 4 weeks elapsed), the functions of liver and kidney, Prostaglandin E2, inflammatory cytokine (IL-$1{\beta}$, IL-6, TNF-${\alpha}$), osteocalcin, TIMP-1, MMP-9 within serum. Knee joint structures were observed by H&E, safranin-O staining method, and amount of cartilage were measured by ${\mu}CT$-arthrography. Results 1) Hind paw weight bearing ability was significantly improved. 2) Functions of liver and kidney were not affected. 3) Prostaglandin E2, osteocalcin, TIMP-1, MMP-9 in serum were significantly decreased. 4) Inflammatory cytokine IL-$1{\beta}$ was significantly decreased, and IL-6, TNF-${\alpha}$ were decreased but had not significant. 5) In terms of histopathology, significantly reduced subsidence of cartilage and bone in H&E staining. And in Safranin O staining, proteoglycan content in synovial membrane was significantly increased compared with control group. 6) Destruction of cartilage on ${\mu}CT$-arthrography was significantly reduced. Conclusions Based on all results mentioned above, Saengkanggamchotang (SKT) is believed to be meaningful for suppressing the progress of osteoarthritis and its treatments.

  • Toxoplasma gondii is an intracellular protozoan parasite that causes a Th1 cellular immunity. Our previous study showed that T. gondii lysate antigen (TLA) treatment in S180 tumor-bearing mice resulted in tumor reduction by suppressing CD31 expression, a marker of angiogenesis. In the present study, to investigate tumor suppressive effect of TLA under the absence of T lymphocytes, athymic nude mice were compared with euthymic mice in the anti-tumorigenic effect triggered by TLA in CT26 tumors. According to the results, intratumorally injected TLA reduced tumor growth and TIMP-1 level, a metastatic marker, in both euthymic and athymic mice. TLA treatment led to a sharp increase in IL-12 expression in serum cytokine profiling of athymic mice, and increased MyD88 signals in macrophages derived from the bone marrow, implying the activation of innate immunity. The selective induction of IL-12 by TLA treatment had an anti-tumorigenic effect.

  • The aim of our study was to evaluate the potential benefits of an oral supplement containing porcine placenta extract (PPE) on skin parameters related to cutaneous physiology and aging. PPEs were administered orally to hairless mice for 12 wk. The effects of oral PPE administration on skin water-holding capacity and Transepidermal Water Loss (TEWL) were similar to those of oral collagen (HYCPU2) administered as a positive control. Magnified photographs and replica images showed a reduction in UVB-induced wrinkle formation after collagen and PPE treatments. PPE treatments ameliorated the thicker skin surface that results from UVB exposure, based on a histological examination of skin tissue. The groups that were orally administered PPE (0.05%, OL; 0.1%, OH group) showed significantly reduced Matrix Metaloproteinase-2 (MMP-2) mRNA expression levels compared with the UVB control (Con), by 33.5% and 35.2%, respectively. The mRNA expression of another collagen-degrading protein, MMP-9, was also significantly lower in the groups that received oral administration of PPE (especially in the OH group) than in the control group. Additionally, oral administration of PPE significantly upregulated tissue inhibitor of metalloproteinase-1 (TIMP-1) and -2 mRNA expression levels compared with expression levels in the control group (p<0.05). This indicates that orally administered PPE activated the expression of Timp-1 and -2, inhibitors of MMP, which is responsible for collagen degradation in skin. Taken together, we propose that long-term oral administration of PPE might have a beneficial effect with respect to skin photo-aging.
