This article reviews the contribution of ion channels to membrane potential, the ion channels
expressed in myometrium, and the effect of ion channel activity on the control of myometrial …

A rise in intracellular calcium (Ca 2+) is central to control of contractile activity in myometrium
(see first and second articles in this issue). In nervous tissue, sodium (Na § entry into tissue …

Changes in Ca2+ signals within the myometrium have important functional consequences,
as they determine contractility. We show that the basic phasic nature of uterine contractions …

Myometrial contractility is a complex and dynamic physiological process that changes
substantially during pregnancy and culminates in childbirth. Uterine contractions are …

The role of Ca (2+)-activated potassium (KCa) channels in the regulation of membrane
potential, intracellular free calcium ([Ca2+] i) and contraction was investigated in uterine …

In order to better understand the mechanisms underlying excitation of the uterus, we have
elucidated the characteristics and functional importance of Ca 2+-activated Cl− currents (I Cl …

The contractility of the human uterus is under the fine control of a variety of interacting
bioactive agents. During labour, the excitability of the uterus is drastically transformed in …

Uterine excitability depends on ion channel activity, the expression of which is regulated by
sexual hormones. We show now that the action of protein kinase A (PKA) on large …

The changes in intracellular free calcium concentration [Ca 2+] i) induced by oxytocin in
single cells of cultured human puerperal myometrium were measured with the calcium …

Large-conductance, calcium-sensitive potassium channels (BK (Ca)) are found at high
density in the pregnant human myometrium. We have investigated, using isolated …
