Multi-Homologous Recombination-Based Gene Manipulation in the Rice Pathogen Fusarium fujikuroi
한국식물병리학회 The Plant Pathology Journal 9 Pages
한국식물병리학회 The Plant Pathology Journal 2016, 32권 3호 1 173-181 (9 pages)
Gene disruption by homologous recombination is widely used to investigate and analyze the function of genes in Fusarium fujikuroi, a fungus that causes bakanae disease and root rot symptoms in rice. To generate gene deletion constructs, the use of conventional cloning methods, which rely on restriction enzymes and ligases, has had limited success due to a lack of unique restriction enzyme sites. Although strategies that avoid the use of restriction enzymes have been employed to overcome this... -
Production and immunogenicity of chimeric virus-like particles containing the spike glycoprotein of infectious bronchitis virus
Lishan Lv, Xiaoming Li, Genmei Liu, Ran Li, Qiliang Liu, Huifang Shen, Wei Wang, Chunyi Xue, Yongchang Cao* 대한수의학회 Journal of Veterinary Science 8 Pages
대한수의학회 Journal of Veterinary Science 2014, 제 15권 제 2호 6 209-216 (8 pages)
Infectious bronchitis virus (IBV) poses a severe threat to the poultry industry and causes heavy economic losses worldwide. Vaccination is the most effective method of preventing infection and controlling the spread of IBV, but currently available inactivated and attenuated virus vaccines have some disadvantages. We developed a chimeric virus-like particle (VLP)-based candidate vaccine for IBV protection. The chimeric VLP was composed of matrix 1 protein from avian influenza H5N1 virus and a... -
Molecular characterization of a 13-amino acid deletion in VP1 (1D) protein and novel amino acid substitutions in 3D polymerase protein of foot and mouth disease virus subtype A/Iran87
Majid Esmaelizad*, Saber Jelokhani-Niaraki, Khadije Hashemnejad, Morteza Kamalzadeh, Mohsen Lotfi 대한수의학회 Journal of Veterinary Science 9 Pages
대한수의학회 Journal of Veterinary Science 2011, 제 12권 제 4호 9 363-371 (9 pages)
The nucleotide sequence of the VP1 (1D) and partial 3D polymerase (3D) coding regions of the foot and mouth disease virus (FMDV) vaccine strain A/Iran87, a highly passaged isolate (∼150 passages), was determined and aligned with previously published FMDV serotype A sequences. Overall analysis of the amino acid substitutions revealed that the partial 3D coding region contained four amino acid alterations. Amino acid sequence comparison of the VP1 coding region of the field isolates revealed... -
Mucosal mast cell-derived chondroitin sulphate levels in and worm expulsion from FcRγ-knockout mice following oral challenge with Strongyloides venezuelensis
Denis Nnabuike Onah, Yukifumi Nawa 대한수의학회 Journal of Veterinary Science 6 Pages
대한수의학회 Journal of Veterinary Science 2004, 제 5권 제 3호 6 221-226 (6 pages)
Mucosal mast cell-derived chondroitin sulphates (sulphated proteoglycans) were assayed in gut washings and homogenate of FcRγ-knockout (KO) and wild-type (WT) C57BL/6 mice challenged with Strongyloides venezuelensis in order to assess their possible role in secondary immunity against enteric nematodes. Groups of immune KO and WT mice were challenged by oral gavage with 300 infective larvae (L3 ). Establishment of infection was assessed by daily faecal analysis to determine the number of eggs... -
Inhibition of β-amyloid1-40 Peptide Aggregation and Neurotoxicity by Citrate
YongHoonPark, Young-JinKim, IlHongSon, HyunDukYang 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 7 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2009, Vol.13 No.4 2 273-279 (7 pages)
The accumulation of Ղ-amyloid (AՂ) aggregates is a characteristic of Alzheimer's disease (AD). Furthermore, these aggregates have neurotoxic effects on cells, and thus, molecules that inhibit AՂ aggregate formation could be valuable therapeutics for AD. It is well known that aggregation of AՂ depends on its hydrophobicity, and thus, in order to increase the hydrophilicity of AՂ, we considered using citrate, an anionic surfactant with three carboxylic acid groups. We... -
Inhibition of Nitric Oxide-induced Neuronal Apoptosis in PC12 Cells by Epigallocatechin Gallate
JiYeonJung, YeonJinJeong, ChangRyoungHan, SunHunKim, HyunJinKim, KiHeonLee, HaOkPark, WonJaeKim 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 8 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2005, Vol.9 No.4 8 239-246 (8 pages)
In the central nervous system, nitric oxide (NO) is associated with many pathological diseases such as brain ischemia, neurodegeneration and inflammation. The epigallocatechin gallate (EGCG), a major compound of green tea, is recognized as protective substance against neuronal diseases. This study is aimed to investigate the effect of EGCG on NO-induced cell death in PC12 cells. Administration of sodium nitroprusside (SNP), a NO donor, decreased cell viability in a dose- and time-dependent... -
Inhibition of Hypoxia-induced Apoptosis in PC12 Cells by Estradiol
JiYeonJung, KwangHoonRoh, YeonJinJeong, SunHunKim, EunJuLee, MinSeokKim, WonMannOh, HeeKyunOh, WonJaeKim 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 8 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2005, Vol.9 No.4 7 231-238 (8 pages)
Neuronal apoptotic events, which result in cell death, are occurred in hypoxic/ischemic conditions. Estradiol is a female sex hormone with steroid structure known to provide neuroprotection through multiple mechanisms in the central nervous system. This study was aimed to investigate the signal transduction pathway of CoCl2-induced neuronal cell death and the inhibitory effects of estradiol. Administration of CoCl2 decreased cell viability in both a dose- and time-dependent manner in PC12 cells.... -
Inhibition of DNA-dependent Protein Kinase by Blocking Interaction between Ku Complex and Catalytic Subunit of DNA-dependent Protein Kinase

Recent studies indicated that cancer cells become resistant to ionizing radiation (IR) and chemotherapy drugs by enhanced DNA repair of the lesions. Therefore, it is expected to increase the killing of cancer cells and reduce drug resistance by inhibiting DNA repair pathways that tumor cells rely on to escape chemotherapy. There are a number of key human DNA repair pathways which depend on multimeric polypeptide activities. For example, Ku heterodimer regulatory DNA binding subunits (Ku70/Ku80)... -
Improving dispersion of multi-walled carbon nanotubes and graphene using a common non-covalent modifier
Youbin Kwon, Wonbo Shim, Seung-Yeol Jeon, Ji-Ho Youk, Woong-Ryeol Yu 한국탄소학회 Carbon Letters 9 Pages
한국탄소학회 Carbon Letters 2016, Vol.20 8 53-61 (9 pages)
The reportedly synergistic effects of carbon nanotubes (CNTs) and graphene hybrids have prompted strong demand for an efficient modifier to enhance their dispersion. Here, we investigated the ability of poly(acrylonitrile) (PAN) to overcome the van der Waals interaction of multi-walled CNTs (MWCNTs) and graphene by employing a simple wrapping process involving ultrasonication and subsequent centrifugation of PAN/MWCNT/graphene solutions. The physical wrapping of MWCNTs and graphene with PAN was... -
