Evaluating the proarrhythmic risk of delayed-action compounds in serum free cell culture conditions; serum-starvation accelerates/amplifies the effect of probucol on the KCNQ1 + KCNE1 channel
{{output}}
In vitro testing procedures for evaluating acute effects of compound on ion channels, utilizing heterologous expression systems (HES), are well-established, while slowly manifesting delayed effects remain challenging to detect. For this, immortalized HES are e... ...
