Disruption of type 5 adenylyl cyclase gene preserves cardiac function against pressure overload

S Okumura, G Takagi, J Kawabe… - Proceedings of the …, 2003 - National Acad Sciences
The sympathetic nervous system is designed to respond to stress. Adenylyl cyclase (AC) is
the keystone of sympathetic transmission, yet its role in response to acute overload in the …

Magma deformation may induce non-explosive volcanism via degassing through bubble networks

S Okumura, M Nakamura, S Takeuchi… - Earth and Planetary …, 2009 - Elsevier
The open-system degassing of magma controls the bifurcation of explosive and non-explosive
volcanism. Permeable gas flow through connected bubbles is a potentially important …

Evolution of bubble microstructure in sheared rhyolite: Formation of a channel‐like bubble network

S Okumura, M Nakamura, A Tsuchiyama… - Journal of …, 2008 - Wiley Online Library
The microstructure of bubbles in magma controls the dynamics of magma flow in a volcanic
conduit. To investigate the shear‐induced evolution of bubble microstructures, we performed …

HER2-specific T-cell immune responses in patients vaccinated with truncated HER2 protein complexed with nanogels of cholesteryl pullulan

…, Y Miyahara, A Hiasa, H Naota, S Okumura… - Clinical cancer …, 2006 - AACR
Purpose: We developed a complex of tumor antigen protein with a novel nanoparticle
antigen delivery system of cholesteryl pullulan (CHP). To target HER2 antigen, we prepared …

[HTML][HTML] Motor dysfunction in type 5 adenylyl cyclase-null mice

T Iwamoto, S Okumura, K Iwatsubo, JI Kawabe… - Journal of Biological …, 2003 - ASBMB
Various neurotransmitters, such as dopamine, stimulate adenylyl cyclase to produce cAMP,
which regulates neuronal functions. Genetic disruption of the type 5 adenylyl cyclase isoform …

[HTML][HTML] Epac1-dependent phospholamban phosphorylation mediates the cardiac response to stresses

S Okumura, T Fujita, W Cai, M Jin… - The Journal of …, 2014 - Am Soc Clin Investig
PKA phosphorylates multiple molecules involved in calcium (Ca 2+ ) handling in cardiac
myocytes and is considered to be the predominant regulator of β-adrenergic receptor–mediated …

Type 5 adenylyl cyclase disruption alters not only sympathetic but also parasympathetic and calcium-mediated cardiac regulation

S Okumura, J Kawabe, A Yatani, G Takagi… - Circulation …, 2003 - Am Heart Assoc
In a genetically engineered mouse line with disruption of type 5 adenylyl cyclase (AC5 −/− ),
a major cardiac isoform, there was no compensatory increase in other isoforms of AC in the …

[HTML][HTML] Simultaneous hyperthermia-chemotherapy with controlled drug delivery using single-drug nanoparticles

…, M Sato, T Fujita, U Yokoyama, S Okumura… - Scientific reports, 2016 - nature.com
We previously investigated the utility of μ-oxo N,N′- bis(salicylidene)ethylenediamine iron (Fe(Salen))
nanoparticles as a new anti-cancer agent for magnet-guided delivery with anti-…

Disruption of type 5 adenylyl cyclase enhances desensitization of cyclic adenosine monophosphate signal and increases Akt signal with chronic catecholamine stress

S Okumura, DE Vatner, R Kurotani, Y Bai, S Gao… - Circulation, 2007 - Am Heart Assoc
Background— Desensitization of the cyclic adenosine monophosphate signal protects cardiac
myocytes against catecholamine stress, thus preventing the development of apoptosis. …

Antitumor activity of CAR-T cells targeting the intracellular oncoprotein WT1 can be enhanced by vaccination

…, M Yoneyama, N Seo, S Okumura… - Blood, The Journal …, 2018 - ashpublications.org
The recent success of chimeric antigen receptor (CAR)-T cell therapy for treatment of
hematologic malignancies supports further development of treatments for both liquid and solid …
