  • Background: Timosaponin AIII (TA3) is a steroidal saponin extracted from Anemarrhena asphodeloides. Here, we investigated the anticancer effects of TA3 in MG63 human osteosarcoma cells. TA3 attenuates migration and invasion of MG63 cells via regulations of two matrix metalloproteinases (MMPs), MMP-2 and MMP-9, which are involved with cancer metastasis in various cancer cells. TA3 reduced enzymatic activities and transcriptional expressions of MMP-2 and MMP-9 in MG63 cells. TA3 also inhibited Src, focal adhesion kinase, extracellular signal-regulated kinase (ERK1/2), c-Jun N-terminal kinase (JNK), p38, ${\beta}-catenin$, and cAMP response element binding signaling, which regulate migration and invasion of cells. TA3 induced apoptosis of MG63 cells via regulations of caspase-3, caspase-7, and poly(ADP-ribose) polymerase (PARP). Then, we tested several ginsenosides to be used in combination with TA3 for the synergistic anticancer effects. We found that ginsenosides Rb1 and Rc have synergistic effects on TA3-induced apoptosis in MG63 cells. Methods: We investigated the anticancer effects of TA3 and synergistic effects of various ginseng saponins on TA3-induced apoptosis in MG63 cells. To test antimetastatic effects, we performed wound healing migration assay, Boyden chamber invasion assays, gelatin zymography assay, and Western blot analysis. Annexin V/PI staining apoptosis assay was performed to determine the apoptotic effect of TA3 and ginsenosides. Results: TA3 attenuated migration and invasion of MG63 cells and induced apoptosis of MG63 cells. Ginsenosides Rb1 and Rc showed the synergistic effects on TA3-induced apoptosis in MG63 cells. Conclusions: The results strongly suggest that the combination of TA3 and the two ginsenosides Rb1 and Rc may be a strong candidate for the effective antiosteosarcoma agent.

  • Background: AD-2 (20(R)-dammarane-3b, 12b, 20, 25-tetrol; 25-OH-PPD) is a ginsenoside and isolated from Panax ginseng, showing anticancer activity against extensive human cancer cell lines. In this study, effects and mechanisms of 1C ((20R)-3b-O-(L-alanyl)-dammarane-12b, 20, 25-triol), a modified version of AD-2, were evaluated for its development as a novel anticancer drug. Methods: MTT assay was performed to evaluate cell cytotoxic activity. Cell cycle and levels of reactive oxygen species (ROS) were determined using flow cytometry analysis. Western blotting was employed to analyze signaling pathways. Results: 1C concentration-dependently reduces prostate cancer cell viability without affecting normal human gastric epithelial cell line-1 viability. In LNCaP prostate cancer cells, 1C triggered apoptosis via Bcl-2 family-mediated mitochondria pathway, downregulated expression of mouse double minute 2, upregulated expression of p53 and stimulated ROS production. ROS scavenger, N-acetylcysteine, can attenuate 1C-induced apoptosis. 1C also inhibited the proliferation of LNCaP cells through inhibition on $Wnt/{\beta}-catenin$ signaling pathway. Conclusion: 1C shows obvious anticancer activity based on inducing cell apoptosis by Bcl-2 family-mediated mitochondria pathway and ROS production, inhibiting $Wnt/{\beta}-catenin$ signaling pathway. These findings demonstrate that 1C may provide leads as a potential agent for cancer therapy.

  • Objectives : The antidepressant effect of the subchronic administration of the methanolic extract of wild ginseng(WG) was investigated compared with that of cultivated ginseng(CG, panax ginseng) extract. Methods : To assess the antidepressant effect of the ginseng extracts, tail suspension test(TST) was executed in mice after daily administration of WG or CG extract for five consecutive days. Results : The WG extract at daily dose of 600mg/kg significantly reduced the total duration of immobility in the TST, whereas there was no significant reduction at daily dose of 300mg/kg WG and 600mg/kg CG. There were no individual differences between experimental groups in open field test (OFT) to evaluate psychostimulant effects of WG or CG extract. In the high performance liquid chromatography(HPLC) analysis of the extracts, it was found that WG included four times more ginsenoside Rg1 and Re, three times more Rf, and six times more Rb1 and Rc than CG. Conclusions : It is suggested that WG extract has stronger antidepressant effect than CG extract, which means it includes more antidepressant compounds than CG.

  • Background: 20(S)-protopanaxadiol (PPD), a ginsenoside metabolite, has prominent benefits for the central nervous system, especially in improving learning and memory. However, its transcriptional targets in brain tissue remain unknown. Methods: In this study, we first used mass spectrometry-based drug affinity responsive target stability (DARTS) to identify the potential proteins of ginsenosides and intersected them with the transcription factor library. Second, the transcription factor PURA was confirmed as a target of PPD by biolayer interferometry (BLI) and molecular docking. Next, the effect of PPD on the transcriptional levels of target genes of PURA in brain tissues was determined by qRT-PCR. Finally, bioinformatics analysis was used to analyze the potential biological features of these target proteins. Results: The results showed three overlapping transcription factors between the proteomics of DARTS and transcription factor library. BLI analysis further showed that PPD had a higher direct interaction with PURA than parent ginsenosides. Subsequently, BLI kinetic analysis, molecular docking, and mutations in key amino acids of PURA indicated that PPD specifically bound to PURA. The results of qRT-PCR showed that PPD could increase the transcription levels of PURA target genes in brain. Finally, bioinformatics analysis showed that these target proteins were involved in learning and memory function. Conclusion: The above-mentioned findings indicate that PURA is a transcription target of PPD in brain, and PPD upregulate the transcription levels of target genes related to cognitive dysfunction by binding PURA, which could provide a chemical and biological basis for the study of treating cognitive impairment by targeting PURA.

  • 인삼(人蔘)사포닌중의 각(各) ginsenosides를 효과적(效果的)으로 분리(分離) 정량(定量)하기 위하여 carbohydrate analysis column을 사용(使用)한 HPLC로 전형적(典型的)인 용매(溶媒) system인 acetonitrile/water의 혼합비율(混合比率)을 80/20에서 94/6까지 조정(調整)하여 retention time과 분리능(分離能)과의 관계(關係)를 비교실험(比較試驗)하였고 또 n-butanol의 첨가효과(添加效果)도 조사(調査)하였다. 기본구조(基本構造)가 다른 diol saponin과 triol saponin을 같은 mobile phase로 만족하게 분리정량(分離定量)하기는 어렵다. 따라서 diol saponin은 acetonitrile/water system(80/20), trol saponin은 acetonitrile/water/n-butanol system(86/14/10)을 mobile phase로 하여 분석(分析)함이 효과적(效果的)이었다. 이 방법(方法)에 따라 백삼(白蔘)과 홍삼(紅蔘)을 정량(定量)한 결과(結果), diol saponin 함량(含量)은 큰 차이(差異)가 없으나 triol saponin 함량(含量)은 홍삼(紅蔘)이 백삼(白蔘)보다 증가(增加)하였다. 특(特)히 PT/PD ratin가 백삼(白蔘)은 0.401인데 비(比)해 홍삼(紅蔘)은 0.561로서 홍삼(紅蔘)이 백삼(白蔘)보다 약 1.4배(倍)나 높았다. 이것이 홍삼(紅蔘)의 생화학적약리효능(生化學的藥理效能)과 깊은 관계(關係)가 있다고 판단(判斷)되며 열처리(熱處理)에 의한 제조공정(製造工程)과 관계(關係)가 있다.

  • 대부분의 신경퇴행성질환은 산화스트레스의 영향을 받는다. 따라서 본 연구에서는 진세노사이드 Rg5와 Rk1을 함유하고 있는 발효산삼배양근 농축액인 HLJG0701의 산화방지 효능을 확인하였다. 그 결과, HLJG0701는 효과적인 DPPH와 ABTS 라디칼제거능을 나타냈으며($IC_{50}$: 16배, 4배 희석액), 황산철(II) 유도군의 지방질 과산화물 발생 비교 시, 용량의존적으로 억제됨을 확인하였다(8배 희석액: 2.3 nM, 4배 희석액: 1.5 nM). HLJG0701의 세포 보호 효과를 MTT, LDH 분석으로 평가한 결과, 8, 16, 32, 64배 희석액의 HLJG0701를 처리한 경우 70, 53, 35, 26%의 세포생존율이 증가됨을 확인하였다. LDH 방출 측정 결과, $H_2O_2$로 인해 3.6배까지 증가한 LDH 활성은 8배 희석액의 HLJG0701 처리 시 1.3배 수준까지 감소하였다. 또한 HLJG0701가 PC12세포에 발생한 산화스트레스 DCF-DA 분석(16배 희석액: 50% ROS 억제, 4배 희석액: 68% ROS 억제), TBARS (16배 희석액: 50.7% 감소, 4배 희석액: 46.5% 감소), GPx (16배 희석액: 133.3% 증가, 4배 희석액: 227.3% 증가), 그리고 SOD (16배 희석액: 118.2% 증가, 4배 희석액: 218.2% 증가) 분석으로 확인하였다. 위 결과는 HLJG0701가 산화방지 효능을 매개로 신경세포를 보호함으로써 신경퇴행성질환을 예방할 수 있는 가능성 있는 후보물질이 될 수 있다는 것을 의미하며, 임상시험 등 다양한 연구가 충분하지 않은 상태이므로 앞으로 지속적인 연구가 필요할 것으로 사료된다.

  • Background: Panax ginseng Meyer is a traditional medicinal plant famous for its strong therapeutic effects and serves as an important herbal medicine. To understand and manipulate genes involved in secondary metabolic pathways including ginsenosides, transcriptome profiling of P. ginseng is essential. Methods: RNA-seq analysis of adventitious roots of two P. ginseng cultivars, Chunpoong (CP) and Cheongsun (CS), was performed using the Illumina HiSeq platform. After transcripts were assembled, expression profiling was performed. Results: Assemblies were generated from ~85 million and ~77 million high-quality reads from CP and CS cultivars, respectively. A total of 35,527 and 27,716 transcripts were obtained from the CP and CS assemblies, respectively. Annotation of the transcriptomes showed that approximately 90% of the transcripts had significant matches in public databases.We identified several candidate genes involved in ginsenoside biosynthesis. In addition, a large number of transcripts (17%) with different gene ontology designations were uniquely detected in adventitious roots compared to normal ginseng roots. Conclusion: This study will provide a comprehensive insight into the transcriptome of ginseng adventitious roots, and a way for successful transcriptome analysis and profiling of resource plants with less genomic information. The transcriptome profiling data generated in this study are available in our newly created adventitious root transcriptome database (http://im-crop.snu.ac.kr/transdb/index.php) for public use.

  • Background: Recently, beneficial roles of ginsenoside F2 (GF2), a minor constituent of Panax ginseng, have been demonstrated in diverse inflammatory diseases. However, its roles in alcoholic liver inflammation and injury have not been clearly understood. Here, we investigated the underlying mechanism by which GF2 ameliorated alcoholic liver injury. Methods: To induce alcoholic liver injury, C57BL/6J wild type (WT) or interleukin (IL)-10 knockout (KO) mice were orally administered with ethanol (3 g/kg) or ethanol-containing GF2 (50 mg/kg) for 2 wk. Liver injury and infiltration of macrophages and neutrophils were evaluated by serum biochemistry and immunohistochemistry, respectively. The changes of hepatic immune cells were assessed by flow cytometry and polymerase chain reaction analysis. In vitro differentiation of naïve T cells was performed. Results: GF2 treatment significantly attenuated alcoholic liver injury, in which infiltrations of inflammatory macrophages and neutrophils were decreased. Moreover, the frequencies of Foxp3+ regulatory T cells (Tregs) increased but IL-17-producing T (Th17) cells decreased in GF2-treated mice compared to controls. Furthermore, the mRNA expression of IL-10 and Foxp3 was significantly increased, whereas IL-17 mRNA expression was suppressed in GF2-treated mice. However, these beneficial roles of GF2 were not observed in GF2-treated IL-10 KO mice, suggesting a critical role of IL-10. Similarly, GF2 treatment suppressed differentiation of naïve T cells into Th17 cells by inhibiting RORgt expression and stimulating Foxp3 expression. Conclusion: The present study suggests that GF2 treatment attenuates alcoholic liver injury by increasing IL-10 expression and Tregs and decreasing IL-17 expression and Th17 cells.

  • 본 연구는 수삼에서 추출된 사포닌 성분 특성 및 이를 혼합한 포크소시지의 소비자 기호성에 미치는 영향을 구명하기 위해 실시되었다. 최적의 수삼사포닌 추출을 위해 에탄올 농도(0, 20, 40, 60, 80, 100%)에 따른 고형분 추출성과 사포닌 함량을 조사한 결과 에탄을 0%(증류수 100%) 추출이 20%로 $20{\sim}80%$(약 15%)와 100%(10%)에탄을 추출보다 더 많은 건조물을 추출하였으나, 조사포닌 함량은 에탄을 함량이 증가와 비례적으로 증가하여 100% 에탄을 추출에서 123.52mg/g으로 가장 높았다. LC/MS로 ginsenosides을 정량한 결과 Rb1, Rb2 및 Rc는 에탄을 80%와 100%에서 공동으로 다른 농도에 비해 유의적(p<0.05)으로 높은 농도를 보였고, Rgl은 60, 80 및 100% 에탄올에서 유의적(p<0.05)으로 높은 추출성을 보였다. 에탈올 100%로 추출한 수삼추출액을 포크소시지에 원료육 중량에 대한 0, 1, 2% 함량으로 각각 첨가하여 훈연과 비훈연 처리로 나누어 소시지 제조 후 향미, 다즙성, 연도, 기호성 등을 펙토리얼 디자인에 의한 관능평가를 실시하였다. 훈연 처리는 다즙성과 연도를 유의적(p<0.05)으로 감소시켰으나 향미와 기호성은 유의적(p<0.05)으로 증가시켰다. 특히 인삼 추출물을 2% 첨가한 소시지는 훈연에 의해서도 다즙성이나 연도가 감소하지 않은(p<0.05) 반면 기호성은 다른 처리군에 비해 유의적(p<0.05)으로 높은 관능검사 점수를 받았다. 이상의 결과는 포크소시지 제조에 인삼 추출물 첨가는 인삼 본래의 기능적 효과를 소비자들에게 제공함은 물론 관능적 특성에서도 더 우수한 제품을 생산할 수 있다는 점을 예시하고 있다. 유의적으로 높게 나타났으며(p<0.05), 연도와 다즙성 및 전체적인 기호도는 처리구가 다소 높은 점수를 얻었다.m$1.0%에 비하여 3일과 5일은 11.0$\pm$0.9%와 8.0$\pm$0.9%로 유의적으로(p<0.05) 낮은 발달율을 나타내었다. 이상의 결과를 종합할 때 항생제가 첨가되지 않은 돼지 혼합 정액은 보관일수 3일째부터 정자의 운동성이 감소하고 세균수는 증가하였다. 또한 보존된 정액을 이용하여 체외 수정을 실시할 경우, 보관일수가 증가할수록 정상 수정율과 체외 발달율이 감소함으로 항생제를 첨가하지 않는 경우 3일 이상 정액을 보관하여 사용하지 않는 것이 바람직 하다고 사료된다. 특성을 유지하였으며 냉각 보관 2주까지 좋은 성적의 정자 특성을 나타냈다. 개 정자 냉각 보존에 대안적인 희석액으로 G-BSA도 사용 가능한 것으로 사료된다.수준이 증가함에 따라 계란 내 항생제 잔류량은 유의하게 감소하였다. 본 연구에서는 육계 사료 내 AC의 첨가 급여가 생산된 계육의 외관적 특성을 개선시키는 효과가 시사되었고, 장내 총균수, 대장균 및 유산균수를 감소시키는 시키는 결과를 보였다. 산란계 사료 내 AC의 첨가 급여가 혈청 및 계란 내 항생제 잔류를 감소시키는 결과를 나타내었다.m의 MIC는 ceftazidime의 MIC에 비해서 상대적으로 높은 양상을 보였다. 이러한 결과는 국내의 대학병원 뿐 만 아니라 일반종합병원에서도 CTX-M형 ESBL 생성 E. coli와 K. pneumoniae가 존재하며 확산 중임을 시사한다. 앞으로 CTX-M형 ESBL의 만연과 변종 CTX-M형 ESBL의 출연을 감시하기 위한 정기적인 연구와 조사가 필요한 것으로 생각한다., A2-1, B1-1, B2-1의
