英文摘要: Abstract(#br)Methamphetamine (MA) is a psychostimulant. MA may induce numerous cardiotoxic effects, leading to cardiac arrhythmias, heart failure, eventually leading to sudden cardiac death. The deleterious effects of methamphetamine work in tandem to disrupt the coordinated electrical activity of the heart and have been associated with life-threatening cardiac arrhythmias. Remodeling of ion channels is an important mechanism of arrhythmia. Although arrhythmogenic remodeling involves alterations in ion channel expression, it is yet unknown whether MA induced electrical remodeling by affecting gene expression, and whether the changes in protein expression are paralleled by alterations in mRNA expression. Our study focused on the expression of ion channels which were correlated to the...
