    Alomone Labs channel kir subunits kir2 1
    Inward rectifier K + current I K1 expression and function in transgenic atrial myocytes. Experimental animals involved wild‐type mice (WT) and transgenic mice (TG) expressing the repressor isoform of cyclic adenosine monophosphate response element modulator, CREM‐IbΔC‐X, and were distributed according to age in 6‐week‐old (WT 6w and TG 6w ) and 12‐week‐old (WT 12w and TG 12w ) groups. A , Representative traces of inward rectifiers K + channel (I K1 ) recorded in WT 12w and TG 12w myocytes before and after application of 10 μmol/L BaCl 2 using a ramp protocol (inset, scale bar 0.2 seconds). The traces show current densitiy (expressed in picoamperes/picofarads [pA/pF]) over time. ( Aa ). Current–voltage plots of I K1 averaged from traces of all cells. For WT 6w , n/N are 8/5, for TG 6w n/N are 10/6, for WT 12w n/N are 13/7, and for TG 12w n/N are 9/6 ( Ab ). B , Data show mean±SE of relative mRNA levels of atrial K + voltage‐gated channel subfamily J member 2 ( Kcnj2 ) and 4 ( Kcnj4 ) normalized to WT 6w vs Hprt1 (hypoxanthine phosphoribosyltransferase 1) as the housekeeping gene; N=8 per group. Y‐axes scale is Log2. Ca through c , Representative immunoblots ( Ca ) and quantification of K + inwardly rectifying channel subunits <t>Kir2.1</t> ( Cb ) and Kir2.3 ( Cc ) protein levels normalized to calsequestrin (CSQ). Data show mean±SE of 7 mice per group. Da through b , Representative action potentials recorded before (normal Tyrode [NT] as control) and after application of 10 μmol/L BaCl 2 in 1 atrial myocyte of each group ( Da ). Quantification of the percentages of action potential duration (APD) change in BaCl 2 vs NT at 50% (APD 50 ) and 90% (APD 90 ) repolarization. Data show mean±SE of n/N for WT 6w (7/5), TG 6w (5/5), WT 12w (11/6), and TG 12w (5/4) ( Db ). * P
