The brm and PARP proteins are degraded in NB4 cells undergoing apoptosis. (A) NB4 cells were treated with 100 J/m2 of UV and then lysed at the times after treatment indicated above the lanes. Cell lysates were used for Western blotting with anti-brm and anti-PARP antibodies. (B) Cells were treated for 2 h with etoposide, camptothecin, or staurosporine at the indicated concentrations and then lysed for Western blotting.
