Sauvadet A, Pavoine C, Rohn T, Pecker F
C R Seances Soc Biol Fil . 1996 Jan; 190(2-3):243-53. PMID: 8869235
The calcium ion plays a unique role as a messenger and a cofactor in cardiac contraction. This role relies on the strict control by the cell of Ca homeostasis, the...

Sauvadet A, Rohn T, Pecker F, Pavoine C
Circ Res . 1996 Jan; 78(1):102-9. PMID: 8603492
It has been recently shown that the physiological processing of glucagon into its C-terminal (19-29) fragment, miniglucagon, by cardiac cells was essential for the contractile positive inotropic effect of the...

Mery P, Pavoine C, Pecker F, Fischmeister R
Mol Pharmacol . 1995 Jul; 48(1):121-30. PMID: 7623766
Recently, an inhibitor of adenosine deaminase, erythro-9-(2-hydroxyl-3-nonyl)adenine (EHNA), was shown to selectively block the activity of purified cGMP-stimulated phosphodiesterase (PDE) (cGS-PDE, or PDE2) in human and porcine heart [J. Mol....

Sauvadet A, Pecker F, Pavoine C
Cell Calcium . 1995 Jul; 18(1):76-85. PMID: 7585885
The effect of mini-glucagon, the metabolite (19-29) of glucagon was examined on the sarcolemmal (SL) Ca2+ pump activity measured in situ, in single quiescent embryonic chick heart ventricular cells loaded...

Mery P, Pavoine C, Belhassen L, Pecker F, Fischmeister R
J Biol Chem . 1993 Dec; 268(35):26286-95. PMID: 7902837
The effects of the nitric oxide (NO) donor 3-morpholino-sydnonimine (SIN-1) on the L-type Ca2+ current (ICa) were examined in frog ventricular myocytes under basal and phosphorylated conditions. SIN-1 was found...

Brechler V, Pavoine C, Hanf R, Garbarz E, Fischmeister R, Pecker F
J Biol Chem . 1992 Aug; 267(22):15496-501. PMID: 1353495
We have recently reported that glucagon activated the L-type Ca2+ channel current in frog ventricular myocytes and showed that this was linked to the inhibition of a membrane-bound low-Km cAMP...

Lotersztajn S, Pavoine C, Deterre P, Capeau J, Mallat A, LeNguyen D, et al.
J Biol Chem . 1992 Feb; 267(4):2375-9. PMID: 1310315
In Zajdela hepatoma cells (ZHC) the plasma membrane Ca2+ pump displayed no sensitivity to glucagon (19-29) (mini-glucagon), whereas in hepatocyte this metabolite of glucagon evoked a biphasic regulation of the...

Pavoine C, Brechler V, Kervran A, Blache P, Le-Nguyen D, Laurent S, et al.
Am J Physiol . 1991 May; 260(5 Pt 1):C993-9. PMID: 1852111
Glucagon is well known for its cardiotonic effect, but its mechanism of action remains undetermined. In the present study, we showed that glucagon, under minimal degradation conditions, had no effect...

Blache P, Kervran A, Dufour M, Martinez J, Le-Nguyen D, Lotersztajn S, et al.
J Biol Chem . 1990 Dec; 265(35):21514-9. PMID: 2147684
Glucagon-(19-29) is 1000-fold more potent that glucagon as an inhibitor of the liver plasma membrane calcium pump, which suggests that this peptide fragment is naturally occurring. Since glucagon-(19-29) is undetectable...

Brechler V, Pavoine C, Lotersztajn S, Garbarz E, Pecker F
J Biol Chem . 1990 Oct; 265(28):16851-5. PMID: 2120208
We studied the effect of adenosine on Na+/Ca2+ exchange activity in ewe heart ventricular sarcolemmal vesicles. Adenosine was found to stimulate Na+/Ca2+ exchange activity in a dose-dependent manner from 0.1...
