Figure 4From: Association of anti-apoptotic Mcl-1L isoform expression with radioresistance of oral squamous carcinoma cellsApoptosis induction and localization of Mcl-1 post-IR. (a) Percentage of apoptosis induction at different time points post-IR by Annexin-V & PI staining analyzed by FACS. The flow cytometry data shown is representative of three independent experiments (*P < 0.05 & **P < 0.01) (b) Immunofluorescence staining of Mcl-1 protein counterstained with DAPI (blue) shows peri-nuclear accumulation (inset) and additional nuclear localization 4 hrs post-IR in AW8507 cells.Back to article page
