Enhanced myocyte contractility and Ca2+ handling in a calcineurin transgenic model of heart failure (2002)

Chu, Guoxiang, Carr, Andrew N., Young, Karen B., Lester, J.William, Yatani, Atsuko, Sanbe, Atsushi, ...

Objective: Impaired myocyte Ca2+ handling is a common characteristic of failing hearts and increases in calcineurin activity, a Ca2+-sensitive phosphatase, have been implicated in heart failure...

PKA-dependent phosphorylation of cardiac myosin binding protein C in transgenic mice (2001)

Yang, Qinglin, Hewett, Timothy E., Klevitsky, Raisa, Sanbe, Atsushi, Wang, Xuejun, Robbins, Jeffrey

Objective: To investigate the physiological role of cAMP-dependent protein kinase A (PKA)-mediated, cardiac myosin binding protein C (MyBP-C) phosphorylation. Methods: A cardiac MyBP-C cDNA lacking...

Desmin-related cardiomyopathy in transgenic mice: A cardiac amyloidosis

Sanbe, Atsushi, Osinska, Hanna, Saffitz, Jeffrey E., Glabe, Charles G., Kayed, Rakez, Maloyan, Alina, ...

An R120G missense mutation in the small heat shock protein α-B-crystallin (CryABR120G) causes desmin-related cardiomyopathy (DRM). DRM is characterized by the formation of aggregates containing...

Reversal of amyloid-induced heart disease in desmin-related cardiomyopathy

Sanbe, Atsushi, Osinska, Hanna, Villa, Chet, Gulick, James, Klevitsky, Raisa, Glabe, Charles G., ...

Amyloid oligomers, similar to the toxic entities found in Alzheimer's disease patients and in other amyloid-based diseases, are present in cardiomyocytes derived from human heart-failure patients and...

Imaging cellular signals in the heart in vivo: Cardiac expression of the high-signal Ca2+ indicator GCaMP2

Tallini, Yvonne N., Ohkura, Masamichi, Choi, Bum-Rak, Ji, Guangju, Imoto, Keiji, Doran, Robert, ...

Genetically encoded sensor proteins provide unique opportunities to advance the understanding of complex cellular interactions in physiologically relevant contexts; however, previously described...

Effects of long-term treatment with trandolapril on sarcoplasmic reticulum function of cardiac muscle in rats with chronic heart failure following myocardial infarction

Yamaguchi, Fuminari, Sanbe, Atsushi, Takeo, Satoshi

Calcium transport activity of isolated cardiac sarcoplasmic reticulum (SR) including Ca2+ uptake and release is decreased in animals with chronic heart failure (CHF) following myocardial infarction....

The effect of chronic treatment with trandolapril on cyclic AMP- and cyclic GMP-dependent relaxations in aortic segments of rats with chronic heart failure

Toyoshima, Hiroko, Nasa, Yoshihisa, Kohsaka, Yumi, Isayama, Yoko, Yamaguchi, Fuminari, Sanbe, Atsushi, ...

Characteristics of cyclic GMP- and cyclic AMP-mediated relaxation in aortic segments of rats with chronic heart failure (CHF) and the effects of chronic treatment with an angiotensin I converting...

Improvement of exercise capacity of rats with chronic heart failure by long-term treatment with trandolapril

Yamaguchi, Fuminari, Kawana, Ken-ichiro, Tanonaka, Kouichi, Kamano, Isamu, Igarashi, Takahiro, Gen, Eigyoku, ...

The effects of long-term treatment with trandolapril, an angiotensin I-converting enzyme inhibitor, on exercise capacity of rats with chronic heart failure (CHF) following coronary artery ligation...

Hyperammonaemia in V1a vasopressin receptor knockout mice caused by the promoted proteolysis and reduced intrahepatic blood volume

Hiroyama, Masami, Aoyagi, Toshinori, Fujiwara, Yoko, Oshikawa, Sayuri, Sanbe, Atsushi, Endo, Fumio, ...

An analysis of arginine-vasopressin (AVP) V1a receptor-deficient (V1aR −/−) mice revealed that glucose homeostasis and lipid metabolism were altered in the mutant mice. Here, we used V1aR −/−...

Insulin hypersensitivity in mice lacking the V1b vasopressin receptor

Fujiwara, Yoko, Hiroyama, Masami, Sanbe, Atsushi, Aoyagi, Toshinori, Birumachi, Jun-ichi, Yamauchi, Junji, ...

We have reported that [Arg8]-vasopressin-stimulated insulin release is blunted in islet cells isolated from V1b receptor-deficient (V1bR−/−) mice. In this study, we used V1bR−/− mice to...
