Inhibitory effects of antioxidants on neonatal rat cardiac myocyte hypertrophy induced by tumor necrosis factor-α and angiotensin II

K Nakamura, K Fushimi, H Kouchi, K Mihara… - Circulation, 1998 - Am Heart Assoc
Background—Tumor necrosis factor-α (TNF-α) and angiotensin II (Ang II) modulate heart
failure in part by provoking the hypertrophic response. Signal transduction pathways of those …

Cell cycle-dependent regulation of phosphorylation of the human retinoblastoma gene product

K Mihara, XR Cao, A Yen, S Chandler, B Driscoll… - Science, 1989 - science.org
The human retinoblastoma gene (RB1) encodes a protein (Rb) of 105 kilodaltons that can
be phosphorylated. Analysis of Rb metabolism has shown that the protein has a half-life of …

[HTML][HTML] Neutrophil elastase acts as a biased agonist for proteinase-activated receptor-2 (PAR2)

R Ramachandran, K Mihara, H Chung… - Journal of Biological …, 2011 - ASBMB
Human neutrophil proteinases (elastase, proteinase-3, and cathepsin-G) are released at
sites of acute inflammation. We hypothesized that these inflammation-associated proteinases …

[HTML][HTML] Neutrophil elastase and proteinase-3 trigger G protein-biased signaling through proteinase-activated receptor-1 (PAR1)

K Mihara, R Ramachandran, B Renaux… - Journal of Biological …, 2013 - ASBMB
Neutrophil proteinases released at sites of inflammation can affect tissue function by either
activating or disarming signal transduction mediated by proteinase-activated receptors (PARs)…

Hyperglycaemic impairment of PAR2-mediated vasodilation: Prevention by inhibition of aortic endothelial sodium-glucose-co-Transporter-2 and minimizing oxidative …

M El-Daly, VKP Venu, M Saifeddine, K Mihara… - Vascular …, 2018 - Elsevier
Hyperglycaemia is a major contributor to diabetic cardiovascular disease with
hyperglycaemia-induced endothelial dysfunction recognized as the initiating cause. Coagulation …

Agonist-biased signaling via proteinase activated receptor-2: differential activation of calcium and mitogen-activated protein kinase pathways

R Ramachandran, K Mihara, M Mathur, MD Rochdi… - Molecular …, 2009 - ASPET
We evaluated the ability of different trypsin-revealed tethered ligand (TL) sequences of rat
proteinase-activated receptor 2 (rPAR 2 ) and the corresponding soluble TL-derived agonist …

Thrombin-mediated direct activation of proteinase-activated receptor-2: another target for thrombin signaling

K Mihara, R Ramachandran, M Saifeddine… - Molecular …, 2016 - ASPET
Thrombin is known to signal to cells by cleaving/activating a G–protein–coupled family of
proteinase-activated receptors (PARs). The signaling mechanism involves the proteolytic …

Mucosal allergic sensitization to cockroach allergens is dependent on proteinase activity and proteinase-activated receptor-2 activation

NG Arizmendi, M Abel, K Mihara… - The Journal of …, 2011 - journals.aai.org
We have shown that proteinase-activated receptor-2 (PAR 2) activation in the airways leads
to allergic sensitization to concomitantly inhaled Ags, thus implicating PAR 2 in the …

[HTML][HTML] Myopia-inhibiting concentrations of muscarinic receptor antagonists block activation of alpha2A-adrenoceptors in vitro

BJ Carr, K Mihara, R Ramachandran… - … & Visual Science, 2018 - iovs.arvojournals.org
Purpose: Myopia is a refractive disorder that degrades vision. It can be treated with atropine,
a muscarinic acetylcholine receptor (mAChR) antagonist, but the mechanism is unknown. …

[HTML][HTML] The pregnane X receptor and its microbiota-derived ligand indole 3-propionic acid regulate endothelium-dependent vasodilation

VKP Venu, M Saifeddine, K Mihara… - American Journal …, 2019 - journals.physiology.org
We proposed that circulating metabolites generated by the intestinal microbiota can affect
vascular function. One such metabolite, indole 3-propionic acid (IPA), can activate the …
