Journal ArticleDOI
Calcium sparks: elementary events underlying excitation-contraction coupling in heart muscle
TL;DR: The calcium spark is the consequence of elementary events underlying excitation-contraction coupling and provides an explanation for both spontaneous and triggered changes in the intracellular calcium concentration in the mammalian heart.
Journal ArticleDOI
Relaxation of arterial smooth muscle by calcium sparks
Mark T. Nelson,Heping Cheng,Michael Rubart,Luis Fernando Santana,Adrian D. Bonev,Harm J. Knot,W. J. Lederer +6 more
TL;DR: KCa channels activated by Ca2+ sparks appeared to hyperpolarize and dilate pressurized myogenic arteries because ryanodine and thapsigargin depolarized and constricted these arteries to an extent similar to that produced by blockers of KCa channels.
Journal ArticleDOI
Defective excitation-contraction coupling in experimental cardiac hypertrophy and heart failure.
Ana María Gómez,Héctor H. Valdivia,Heping Cheng,Miriam R. Lederer,Luis Fernando Santana,Mark B. Cannell,S. A. McCune,Ruth A. Altschuld,W. J. Lederer +8 more
TL;DR: The same defect in EC coupling that develops during hypertrophy may contribute to heart failure when compensatory mechanisms fail because it appears to reside in a change in the relation between SR calcium-release channels and sarcolemmal calcium channels.

Superoxide Flashes in Single Mitochondria
Wang Wang,Huaqiang Fang,Linda Groom,Aiwu Cheng,Wanrui Zhang,Jie Liu,Xianhua Wang,Kaitao Li,Peidong Han,Ming Zheng,Jinhu Yin,Weidong Wang,Mark P. Mattson,Joseph P. Y. Kao,Edward G. Lakatta,Shey-Shing Sheu,Kunfu Ouyang,Ju Chen,Robert T. Dirksen,Heping Cheng +19 more
TL;DR: It is shown that individual mitochondria undergo spontaneous bursts of superoxide generation, termed "superoxide flashes", and proposed that superoxide flashes could serve as a valuable biomarker for a wide variety of oxidative stress-related diseases.
