Paclitaxel inhibits the hyper-activation of spleen cells by lipopolysaccharide and induces cell death
Hyun-Ji Kim, Hong-Gu Joo 대한수의학회 Journal of Veterinary Science 6 Pages
대한수의학회 Journal of Veterinary Science 2016, 제 17권 제 4호 3 453-458 (6 pages)
Paclitaxel was isolated from the bark of the Pacific yew, Taxus brevifolia, and used as an anticancer agent. Paclitaxel prevents cancer cell division by inhibiting spindle fiber function, inducing cell death. A recent study demonstrated that paclitaxel binds to myeloid differentiation protein-2 of Toll-like receptor 4 and prevents the signal transduction of lipopolysaccharide (LPS). Paclitaxel converts immune cells hypo-responsive to LPS. In this study, we investigated whether paclitaxel can... -
The role of Bcl-xL and nuclear factor-kB in the effect of taxol on the viability of dendritic cells
Mi-Hyoung Kim, Hong-Gu Joo* 대한수의학회 Journal of Veterinary Science 5 Pages
대한수의학회 Journal of Veterinary Science 2009, 제 10권 제 2호 2 99-103 (5 pages)
Taxol has been used effectively in cancer therapies. Our previous study demonstrated that taxol induced altered maturation and improved viability of dendritic cells (DCs). However, the effects of taxol on DC viability have not been fully elucidated. In the present study, flow cytometric analyses revealed that taxol treatment significantly increased the number of viable DCs and the expression levels of a representative anti-apoptotic protein Bcl-xL. Furthermore, mobilization of the p65 subunit of... -
The efficacy of combination treatment of gabapentin and electro-acupuncture on paclitaxel-induced neuropathic pain
MinJoonKim, JiHwanLee, JoUngJang, FuShiQuan, SunKwangKim, WoojinKim 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 10 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2017, Vol.21 No.6 11 657-666 (10 pages)
Paclitaxel, a chemotherapeutic drug, induces severe peripheral neuropathy. Gabapentin (GBT) is a first line agent used to treat neuropathic pain, and its effect is mediated by spinal noradrenergic and muscarinic cholinergic receptors. Electro-acupuncture (EA) is used for treating various types of pain via its action through spinal opioidergic and noradrenergic receptors. Here, we investigated whether combined treatment of these two agents could exert a synergistic effect on paclitaxel-induced... -
Comparison of Microbial Community of Rhizosphere and Endosphere in Kiwifruit
Min-Jung Kim, Heeil Do, Gyeongjun Cho, Rae-Dong Jeong, Youn-Sig Kwak 한국식물병리학회 The Plant Pathology Journal 7 Pages
한국식물병리학회 The Plant Pathology Journal 2019, 35권 6호 17 705-711 (7 pages)
Understanding the microbial community and function are crucial knowledge for crop management. In this study, bacterial and fungal community structures both rhizosphere and endosphere in kiwifruit were analyzed to gain our knowledge in kiwifruit microbiome. Microbial community in rhizosphere was less variation than endosphere community. Functional prediction results demonstrated that abundance of saprotrophic fungi was similar in both rhizosphere and endosphere, but potential pathogenic fungi was... -
Biocontrol of Citrus Canker Disease Caused by Xanthomonas citri subsp. citri Using an Endophytic Bacillus thuringiensis
Nurul Islam, Sarafat Ali, Seong-Jin Choi, Jae-Wook Hyun, Kwang-Hyun Baek 한국식물병리학회 The Plant Pathology Journal 12 Pages
한국식물병리학회 The Plant Pathology Journal 2019, 35권 5호 9 486-497 (12 pages)
Citrus canker is a devastating disease of citrus caused by Xanthomonas citri subsp. citri (Xcc). A total of 134 endophytic bacteria were isolated from various gymnospermic and angiospermic plants. They were screened for their antagonistic activities against three wild-type and six streptomycin-resistant Xcc strains. TbL-22 and TbL-26, both later identified as Bacillus thuringiensis, inhibited all the wild and resistant Xcc strains. TbL-22 exerted the highest antagonistic activity against XccW3... -
주목 세포배양에서 초기 접종농도와 기본배지가 세포증식과 Taxol 생산에 미치는 영향
황용순, 김석우 한국생물공학회 한국생물공학회지 6 Pages
한국생물공학회 한국생물공학회지 1996, Vol.11 No.5 600-605 (6 pages)
Taxus brevifolia와 Taxus cuspidata 현탁세포배 양에서 taxa!의 생산에 가장 적합한 초기 접종농도 를 결정하기 위해 접종농도를 세포생체중량으로 2.5, 5 5, 7.5, 10 g/flask가 되도록 변화시켜 세포의 생장 과 taxol의 생산을 측정하였다. Taxus brevifolia의 경우 초기 접종농도가 높을수록 lag phase가 감소되 는 경향을 보였으며, 두 가지 세포주(Taxus bre1 vifolia와 Taxus cuspidata)에서 모두 초기 접종농도 를 5 g/flask가 taxol의 생산에 최척 임을 확인할 수 있었다. Taxol 생산에 가장 척합한 초기 접종농도로 생장배지와... -
주목세포배양에 의한 Taxol 생산: 여러 가지 Elicitor가 미치는 영향
윤정환, 김진훈 한국생물공학회 한국생물공학회지 6 Pages
한국생물공학회 한국생물공학회지 1995, Vol.10 No.2 143-148 (6 pages)
Taxus brevifolia 현탁세포배양에 서 항암제 taxol의 생산을 향상시키기 위해 5종류의 biotic elicitor 와 5종류의 abiotic elicitor, 2종류의 대사억제 및 8종류의 생장조절제를 세포배양 중에 첨가하여 효과 가 았는 물질을 선별하였다. T. brevifo/ia 현탁세포 배양의 대수증식기 말기인 10일째에 각각의 물질을 첨가하여 배양액 내의 taxol의 함량을 측정한 결과 steroid계 억제제 인 chlorocholine chloride를 처리 하였을 때 taxol의 생성이 현저히 증가되었다. Chloro choline chloride의 처리시기 및 처리농도를 다르게 하여...
