摘要：
We investigated the effect of dietary cholesterol on gene transcription of delayed rectifier (I-Kr - ERG1 and IKs - KvLQT1) and transient outward (I-to,I-fast - Kv4.2 and Kv4.3) potassium channel subunits in rabbit hearts using real-time quantitative reverse transcription-polymerase chain reaction (RTPCR). While the level of Kv4.3 mRNA did not change, both Kv4.2 and ERG1 mRNAs were downregulated, whereas the level of KvLQT1 was increased in hypercholesterolaemic rabbits, indicating that hypercholesterolaernia altered ventricular K+ channel alpha-subunit gene transcription.
