Note : Open Access ; AltMV TGB1 Nucleolar Localization Requires Homologous Interaction and Correlates with Cell Wall Localization Associated with Cell-to-Cell Movement
한국식물병리학회 The Plant Pathology Journal 6 Pages
한국식물병리학회 The Plant Pathology Journal 2013, 29권 4호 13 454-459 (6 pages)
on the properties of the TGB1 protein. The TGB1 of AltMV has functions including RNA binding, RNA silencing suppression, and cell-to-cell movement, and is known to form homologous interactions. The helicase domains of AltMV TGB1 were separately mutated to identify which regions are involved in homologous TGB1 interactions. The yeast two hybrid system and Bimolecular Fluorescence Complementation (BiFC) in planta were utilized to examine homologous interactions of the mutants. Helicase motif I of... -
Establishment and evaluation of a murine ανβ3-integrin- expressing cell line with increased susceptibility to Foot- and-mouth disease virus

Integrin ανβ3 plays a major role in various signaling pathways, cell apoptosis, and tumor angiogenesis. To examine the functions and roles of ανβ3 integrin, a stable CHO-677 cell line expressing the murine ανβ3 heterodimer (designated as “CHO-677-mανβ3” cells) was established using a highly efficient lentiviral-mediated gene transfer technique. Integrin subunits αν and β3 were detected at the gene and protein levels by polymerase chain reaction (PCR) and indirect... -

FanhuaKong, RunqiZhang, XudongZhao, GuanlinZheng, ZhouWang, PengWang 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 10 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2017, Vol.21 No.5 2 465-474 (10 pages)
The aim of this study was to determine the raising anticancer effects of resveratrol (Res) on paclitaxel (PA) in non-small cell lung cancer (NSCLC) cell line A549. The 10 µg/ml of Res had no effect on human fetal lung fibroblast MRC-5 cells or on A549 cancer cells and the 5 or 10 µg/ml of PA also had no effect on MRC-5 normal cells. PA-L (5 µg/ml) and PA-H (10 µg/ml) had the growth inhibitory effects in NSCLC cell line A549, and Res increased these growth inhibitory... -

Cilostazol is a selective inhibitor of phosphodiesterase 3 that increases intracellular cAMP levels and activates protein kinase A, thereby inhibiting vascular smooth muscle cell (VSMC) proliferation. We investigated whether AMP-activated protein kinase (AMPK) activation induced by heme oxygenase-1 (HO-1) is a mediator of the beneficial effects of cilostazol and whether cilostazol may prevent cell proliferation and reactive oxygen species (ROS) production by activating AMPK in VSMC. In the... -
Losartan Inhibits Vascular Smooth Muscle Cell Proliferation through Activation of AMP-Activated Protein Kinase

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2010, Vol.14 No.5 8 299-304 (6 pages)
Losartan is a selective angiotensin II (Ang II) type 1 (AT1) receptor antagonist which inhibits vascular smooth muscle cells (VSMCs) contraction and proliferation. We hypothesized that losartan may prevent cell proliferation by activating AMP-activated protein kinase (AMPK) in VSMCs. VSMCs were treated with various concentrations of losartan. AMPK activation was measured by Western blot analysis and cell proliferation was measured by MTT assay and flowcytometry. Losartan dose- and... -
Induction of Heme Oxygenase-1 by Traditional Herb Mix Extract Improves MKN-74 Cell Survival and Reduces Stomach Bleeding in Rats by Ethanol and Aspirin in vivo

Chinese herb medicines have traditionally been used to treat or alleviate the symptom of various diseases. The rationale for use of certain herbs to certain disorder is now getting unveiled by modern technology. In the present study, we investigated whether herb mix extract (HMX), which is alleged to be useful for gastric ulcer, protects stomach from oxidative stress. Rats were allowed to normal diet with and without HMX (1, 5, 10 mg/kg) for 30 days. To induce gastric ulcer, ethanol (75%, 1.5... -

본 논문은 다중 안테나를 가진 릴레이가 설치된 다중-셀 다중-사용자 시스템에서 부분 채널 정보를 이용하여 기지국과 릴레이 간 협력적으로 전력을 할당하는 기법을 제안한다. 이중-흡 MISO (Multi-Input Single-Output) 릴레이 채널에서, 릴레이 채널 용량(end-to-end capacity)을 최대화하기 위해 홉 간 송신 전력을 채널 상태에 따라 동적으로 할당할 필요가 있다. 제안된 기법은 목표 릴레이의 평균 채널 이득과 인접 릴레이로부터의 원하는 채널과 간섭 채널의 송신 상관 행렬의 주요한 고유벡터의 상대적인 각도 차이를 고려하여... -

채널 상태까지 고려하여 serving cell을 선택하기 때문에 serving cell 선택 과정의 복잡도가 증가하며, 백홀 링크의 채널 상태가 좋지 않아서 serving cell을 eNB로 선택한 경우에 RN에 의한 강한 간섭의 영향으로 수산 신호가 열화되는 문제점을 가지고 있다. 따라서, 이러한 문제점들을 해결하기 위하여 RN이 백홀 링크의 수신 SINR (Signal to Interference plus Noise Ratio) 에 따라 송신 전력을 조절하는 power control 기법을 제안하며, 다양한 모의실험을 이용한 성능 분석을 통해 제안하는 방식이 3GPP LTE-Advanced 시스템의... -

주파수 재 사용률이 1인 OFDMA(Orthogonal Frequency Division Multiple Access) 시스템에서는 인접한 셀에서 동일채널을 사용하는 것은 셀 간 간섭(Inter-cell-Interference)이 발생하므로 셀 간 간섭을 최소로 하는 채널할당이 이루어져야 한다. 본 논문에서는 OFDMA환경에서 새로운 최대 CNIR(Carrier to Noise and Interference Ratio) 기반의 분산형 Inter-cell DCA (Dynamic Channel Allocation) 알고리즘을 제안한다. 제안된 Inter-cell DCA 알고리즘은 자신의 셀에서 채널할당 요구 시 자신의 셀 내에서 채널이 포화상태이거나...
