Fig. 2. Caspase-dependent cleavage of SAS-6 and pericentrin during apoptosis.
a HeLa cells were treated with paclitaxel or staurosporine for 24 h and subjected to immunoblot analyses with antibodies specific to SAS-6, pericentrin (PCNT), PARP-1, and GAPDH. b HeLa cells were treated with etoposide, staurosporine, or paclitaxel in the presence of IDN-6566 for 24 h. The cells were subjected to immunoblot analyses with indicated antibodies
