Regulation of Na,K-ATPase beta 1 subunit gene transcription by low external potassium in cardiac myocytes. Role of Sp1 AND Sp3.

The Journal of biological chemistry - 4 Aug 2000

Zhuang Y, Wendt C, Gick G

Abstract excerpt

Expression of Na,K-ATPase activity is up-regulated in cells incubated for extended intervals in the presence of low external K(+). Our previous data showed that exposure of cardiac myocytes to low K(+) increased the steady-state abundance of Na,K-ATPase beta1 subunit mRNA. In the present study we determined that incubation of primary cultures of neonatal rat cardiac myocytes with low K(+) augmented Na,K-ATPase...
