of PhE-contraction with L-type Ca2+ channel blocker (nifedipine, 1 μM), plumbagin still induced tonic contraction, suggesting Ca2+-sensitization mechanism of smooth muscle. Although ΔTPlum was consistently observed under pretreatment with Rho A-kinase inhibitor (Y27632, 1 μM), a PKC inhibitor (GF 109203X, 10 μM) largely suppressed ΔTPlum. Taken together, it is suggested that plumbagin facilitates the PKC activation in the presence of vasoactive agonists in skeletal arteries. The biphasic... -

Transient receptor potential vanilloid 3 (TRPV3) is a non-selective cation channel with modest permeability to calcium ions. It is involved in intracellular calcium signaling and is therefore important in processes such as thermal sensation, skin barrier formation, and wound healing. TRPV3 was initially proposed as a warm temperature sensor. It is activated by synthetic small-molecule chemicals and plantderived natural compounds such as camphor and eugenol. Schisandra chinensis (Turcz.) Baill... -
선택적 COX-2 억제제 NS 398과 EGF 수용체 차단제 AG 1478의 복합투여가 HeLa 세포주의 방사선 감수성에 미치는 영향

목적 : 분자 표적의 선택적 억제가 방사선 세포 살상 효과를 증진시키는 것으로 알려져 있으므로 선택적 COX-2 억제제와 EGF 수용체 차단제를 HeLa 세포주에 처리한 후 방사선 효과의 상승작용을 알아보고자 하였다. 대상 및 방법 : 자궁경부암 세포주인 HeLa세포에서 EGF 수용체 차단제 AG 1478, 선택적 COX-2 억제제 NS 398과 방사선을 복합 투여하여 세포성장 억제 분석(cell graph inhibition assay)과 세포사멸 분석(apoptosis assay)을 시행하였고, 방사선 감수성 변화를 살펴보기 위해 세포생존 분석(clonogenic survival assay)을... -
The Critical Roles of Zinc: Beyond Impact on Myocardial Signaling

Zinc has been considered as a vital constituent of proteins, including enzymes. Mobile reactive zinc (Zn2+) is the key form of zinc involved in signal transductions, which are mainly driven by its binding to proteins or the release of zinc from proteins, possibly via a redox switch. There has been growing evidence of zinc’s critical role in cell signaling, due to its flexible coordination geometry and rapid shifts in protein conformation to perform biological reactions. The importance and...
