(A) TUNEL assay showing that MG132 inhibited a high dose of UV irradiation induced apoptosis. HeLa cells were treated with MG132 (5 µM) or DMSO for 60 min before UV treatment. A UV-C crosslinker was used to expose cells at a dose of 100 J/m2. TUNEL assay was performed using the In Situ Cell Death Detection Kit (Roche).
