Intracellular calcium concentration and hormone secretion are controlled differently by TRH in rat neonatal lactotrophs and somatotrophs
Autor: G Horvath, A Lorsignol, B Dufy, Anne Taupignon
Publikováno v: Journal of Endocrinology. 154:483-494
We studied the effects of TRH on the cytosolic free calcium concentration ([Ca2+]i) of female rat pituitary prolactin-secreting (lactotroph) and GH-secreting (somatotroph) cells in the early postnatal period, i.e. at postnatal days 5 and 10. [Ca2+]i

Stimulation of Ca2+ influx in rat pituitary cells under exposure to a 50 Hz magnetic field
Autor: E Barbier, B Dufy, Bernard Veyret
Publikováno v: Bioelectromagnetics. 17:303-311
The effect of exposure of single rat pituitary cells to 50 Hz sine wave magnetic fields of various strengths on the intracellular free Ca2+ concentration ([Ca2+]i), was studied by using dual-emission microfluorimetry, using indo-1 as probe. A 30 min

Interactions between intracellular chloride concentrations, intracellular pH and energetic status in rat lactotrope cells in primary culture
Autor: P, Sartor, F, Madec, L, Garcia, L, Dejean, B, Beauvoit, B, Dufy, M, Rigoulet
Publikováno v: General physiology and biophysics. 23(2)
Rat lactotrope cells in primary cultures have a higher intracellular Cl- concentration ([Cl-]i) than that predicted by a passive distribution across the membrane. This suggests that active cellular mechanisms ensure this ionic equilibrium. In this st

Regulation of intracellular chloride concentration in rat lactotrope cells and its relation to the membrane resting potential
Autor: P, Sartor, L, Garcia, F, Madec, L, Dufy-Barbe, M, Rigoulet, B, Dufy
Publikováno v: General physiology and biophysics. 23(2)
Rat lactotrope cells in primary culture exhibit physiological properties closely associated with chloride ions (Cl-) homeostasis. In this work, we studied the regulation of intracellular Cl- concentrations ([Cl-]i) and its relation to the membrane re

Potassium channel inhibition reduces cell proliferation in the GH3 pituitary cell line
Autor: S, Vaur, L, Bresson-Bepoldin, B, Dufy, S, Tuffet, L, Dufy-Barbe
Publikováno v: Journal of cellular physiology. 177(3)
Potassium (K+) conductances are known to be involved in cell proliferation of a number of nonexcitable cell types. The nature of the mechanism by which K+ channel inhibition reduces cell proliferation has remained elusive despite intensive search. We

Prolactin induces an inward current through voltage-independent Ca2+ channels in Chinese hamster ovary cells stably expressing prolactin receptor
Autor: R. Skryma, N. Prevarskaya, M Fahmi, B. Fournier, D. Ratovondrahona, M.F. Odessa, J Djiane, B. Dufy
Publikováno v: Journal of Molecular Endocrinology
Journal of Molecular Endocrinology, BioScientifica, 1998, 21, pp.85-95
There is still only limited understanding of the early steps of prolactin (PRL) signal transduction in target cells. Recent studies have identified some of the essential first steps: these include the rapid association of the PRL receptor with JAK ty

Potassium conductance in the androgen-sensitive prostate cancer cell line, LNCaP: involvement in cell proliferation
Autor: R N, Skryma, N B, Prevarskaya, L, Dufy-Barbe, M F, Odessa, J, Audin, B, Dufy
Publikováno v: The Prostate. 33(2)
Very little is known about the expression of ion channels in prostate cells (both normal and malignant), and their possible role in physiological and pathological functions. We therefore studied ion conductances and their role in the proliferation of

Role of tyrosine phosphorylation in potassium channel activation. Functional association with prolactin receptor and JAK2 tyrosine kinase

Publikováno v: The Journal of biological chemistry. 270(41)
Chinese hamster ovary (CHO) cells, stably transfected with the long form of the prolactin (PRL) receptor (PRL-R) cDNA, were used for PRL-R signal transduction studies. Patch-clamp technique in whole cell and cell-free configurations were employed. Ex
