Antisense oligodeoxynucleotides (AS-ODNs) were used in combination with transient functional expression of the cardiac Na⁺–Ca²⁺ exchanger (NCX1) to correlate suppression of the Na⁺–Ca²⁺ exchange function with down-regulation of NCX1 protein expression. In a de-novo expression system (Sf9 cells), a decrease in both, NCX1 mRNA and protein after AS-ODN application was paralleled by...
