Effects of hydrogen peroxide on voltage-dependent K+ currents in human cardiac fibroblasts through protein kinase pathways

Bae H, Lee D, Kim YW, Choi J, Lee HJ, Kim SW, Kim T, Noh YH, Ko JH, Bang H, Lim I

Human cardiac fibroblasts (HCFs) have various voltage-dependent K+ channels (VDKCs) that can induce apoptosis. Hydrogen peroxide (H2O2) modulates VDKCs and induces oxidative stress, which is the main contributor to cardiac...

Activation of the cGMP/Protein Kinase G Pathway by Nitric Oxide Can Decrease TRPV1 Activity in Cultured Rat Dorsal Root Ganglion Neurons

Jin Y, Kim J, Kwak J

Recent studies have demonstrated that nitric oxide (NO) activates transient receptor potential vanilloid subtype 1 (TRPV1) via S-nitrosylation of the channel protein. NO also modulates various cellular functions via activation...

Modulation of Ca2+ activated potassium channels by cGMP-dependent signal transduction mechanism in cerebral arterial smooth muscle cells of the rabbit

Han J, Kim N, Lee K, Kim E

  • KMID: 1581022
  • Korean J Physiol Pharmacol.
  • 2000 Dec;4(6):445-453.
The present investigation tested the hypothesis that the activation of protein kinase G (PKG) leads to a phosphorylation of Ca2+-activated potassium channel (KCa channel) and is involved in the activation of KCa channel...

Cinnamyl alcohol attenuates vasoconstriction by activation of K+ channels via NO-cGMP-protein kinase G pathway and inhibition of Rho-kinase

Kang YH, Yang IJ, Morgan KG, Shin HM

  • KMID: 1402319
  • Exp Mol Med.
  • 2012 Dec;44(12):749-755.
Cinnamyl alcohol (CAL) is known as an antipyretic, and a recent study showed its vasodilatory activity without explaining the mechanism. Here we demonstrate the vasodilatory effect and the mechanism of...

Nitric Oxide Prevents the IFN-gamma/LPS-induced Hepatocytic Cell Death in a Protein Kinase G-independent Manner

Chung SY, Choi SJ, Kim SK, So HS, Jung BH, Song HS, Kim MS, Park JS, Chae KM, Lee JH, Che HJ, Kim HR, Chung HT, Park R

  • KMID: 1807464
  • Chonnam Med J.
  • 2000 Jun;36(2):209-218.
Although it has been well known that the role of LPS on liver damage is mediated through TNF-alpha, the direct cytotoxic effect of LPS on IFN-gamma-primed hepatocytes has not yet...

PPARgamma modulates vascular smooth muscle cell phenotype via a protein kinase G-dependent pathway and reduces neointimal hyperplasia after vascular injury

Yang HM, Kim BK, Kim JY, Kwon YW, Jin S, Lee JE, Cho HJ, Lee HY, Kang HJ, Oh BH, Park YB, Kim HS

  • KMID: 2154284
  • Exp Mol Med.
  • 2013 Nov;45(11):e65.
Vascular smooth muscle cells (VSMCs) undergo phenotypic changes in response to vascular injury such as angioplasty. Protein kinase G (PKG) has an important role in the process of VSMC phenotype...

Dendroaspis natriuretic peptide regulates the cardiac L-type Ca2+ channel activity by the phosphorylation of alpha1c proteins

Park SA, Kim TG, Han MK, Ha KC, Kim SZ, Kwak YG

  • KMID: 1383798
  • Exp Mol Med.
  • 2012 Jun;44(6):363-368.
Dendroaspis natriuretic peptide (DNP), a new member of the natriuretic peptide family, is structurally similar to atrial, brain, and C-type natriuretic peptides. However, the effects of DNP on the cardiac...

Action mechanisms of NANC neurotransmitters in smooth muscle of guinea pig ileum

Lee YH, Kim JH, Kang BS

  • KMID: 2285197
  • Korean J Physiol Pharmacol.
  • 1997 Dec;1(6):783-796.
The relaxation induced by stimulation of the inhibitory non-adrenergic, non-cholinergic (iNANC) nerve is mediated by the release of iNANC neurotransmitters such as nitric oxide (NO), vasoactive intestinal peptide (VIP) and adenosine triphosphate (ATP)....

Role of PKG-L-type calcium channels in the antinociceptive effect of intrathecal sildenafil

Kim WM, Yoon MH, Cui JH

Sildenafil increases the cyclic guanosine monophosphate (cGMP) by inhibition of a phosphodiesterase 5, thereby leading to an antinociceptive effect. The increased cGMP may exert the effect on an L-type calcium...
