Los Angeles, United States. In Pulm Circ, 2011
Transcripts of (a) two Na(+) channel α-subunit genes (SCN5A and SCN6A), (b) six Ca(2+) channel α-subunit genes (α(1A), α(1B), α(1x), α(1D), α(1E) and α(1G)) and many regulatory subunits (α(2)δ(1), β(1-4), and γ(6)), (c) 22 Kv channel α-subunit genes (Kv1.1 - Kv1.7, Kv1.10, Kv2.1, Kv3.1, Kv3.3, Kv3.4,
Bone morphogenetic protein-2 upregulates expression and function of voltage-gated K+ channels in human pulmonary artery smooth muscle cells.
San Diego, United States. In Am J Physiol Lung Cell Mol Physiol, 2006
BMP-2 (100 nM for 18-24 h) significantly (>2-fold) upregulated mRNA expression of KCNA5, KCNA7, KCNA10, KCNC3, KCNC4, KCNF1, KCNG3, KCNS1, and KCNS3 but downregulated (at least 2-fold) KCNAB1, KCNA2, KCNG2, and KCNV2.
Gene expression profiling of human cardiac potassium and sodium channels.
Szeged, Hungary. In Int J Cardiol, 2006
Further, we found that the expression levels of Kv1.5 and Kv2.1 transcripts in the ventricle were very high, and that mRNAs for Kv1.7 and Kv3.4 are highly abundant in both the atrium and ventricle, which might indicate a functional role of these ion channel subunits in the formation of action potential in the human ventricle and both in the atrium and ventricle, respectively.

Kv1.2, Kv1.4, and Kv1.7) with the exception of Kv1.5 (EC50, 7.7 nM) and showed no effect on human ether-a-go-go-related channel, Kv3.1, the calcium-activated K+ channels (IKCa1, SK1-SK3, and BKCa), or the neuronal NaV1.2 channel.
