This study aimed to assess the expression of ERG1-3 (KCNH1-3) genes in the murine myometrium (smooth muscle layer of the uterus) and determine the functional impact of the ion channels encoded by these genes in pregnant and non-pregnant animals.

Three types of outward currents were found in hMSCs, including a noise-like rapidly activating outward current inhibited by the large conductance Ca (2+)-activated K (+) channel (I (KCa)) blocker iberiotoxin, a transient outward K (+) current (I (to)) suppressed by 4-aminopyridine (4-AP), and a delayed rectifier K (+) current (IK (DR))-like ether-a-go-go (eag) K (+) channel.

RT-PCR results confirmed the presence of ion channels at the mRNA level: Kv1.1, Kv2.1, Kv1.5, Kv7.3, Kv11.1, and hEAG1, possibly encoding I (KDR); MaxiK, KCNN3, and KCNN4 for I (KCa); Kv1.4, Kv4.1, Kv4.2, and Kv4.3 for I (to) and hNE-Na for I (Na.TTX).
The I (KDR) was inhibited by tetraethyl ammonium (TEA) and 4-aminopyridine (4-AP), which significantly reduced the proliferation of hASCs in a dose-dependent manner (P < 0.05), as suggested by bromodeoxyurindine (BrdU) incorporation.
