Caspase-10B is highly unstable, in contrast to other caspase-10 isoforms. (a) Whole cell extracts from SW480 and SH-EP cells overexpressing the indicated caspase-10 isoforms, untreated or treated with 20 ug/ml of CHX for various times, were analysed by immunoblotting for the presence of caspases-10, -8 and β-actin. (b) Whole cell extracts from SW480 and SH-EP-infected cells untreated or treated with 20 ug/ml of CHX, with or without lactacystin (10 μM for SH-EP or 50 μM for SW480) for 16 h, were analysed as in (a)
