Journal ArticleDOI

Doxorubicin-induced reactive oxygen species generation and intracellular Ca2+ increase are reciprocally modulated in rat cardiomyocytes.

TL;DR: Doxorubicin-mediated ROS opens ryanodine receptor, resulting in an increase in Ca2+i and that the increased [Ca2+]i induces ROS production, suggesting that DOX/ROS-induced increase of [Ca 2+] i plays a critical role in damage of cardiomyocytes.
Journal ArticleDOI

Feedback regulation of phospholipase C-beta by protein kinase C.

TL;DR: It is proposed that rather than having a direct effect on enzyme activity, the phosphorylation of PLC-beta by PKC may alter its interaction with a putative guanine nucleotide-binding regulatory protein and thereby prevent its activation.
Journal ArticleDOI

Ca2+ Signaling Tools Acquired from Prostasomes Are Required for Progesterone-Induced Sperm Motility

TL;DR: It is shown that a long-lasting Ca2+ signal required for sperm motility in response to progesterone depends on their pH-dependent fusion with prostasomes, which are small vesicles secreted by the prostate.
Journal ArticleDOI

Tyrosine residues in bovine phospholipase C-gamma phosphorylated by the epidermal growth factor receptor in vitro.

TL;DR: It is proposed that the phosphorylation of PLC-gamma by EGF receptor kinase alters its interaction with putative inhibitory proteins and leads to its activation.
