Apoptosis of c-Rel overexpressed human B-cells. EREB2-5 cells were stably transfected with the doxycycline-regulatable pRT-1 vector coding for Luciferase (Luc), IκBα S32,36A, IκBε, or c-Rel. After estradiol starvation for 24 h (EREB0), cells were treated with doxycycline (+ Dox) for 48 h. (A) Immunoblots detecting the expression of RelA, RelB, c-Rel, IκBα, IκBε, TRAF1, A20 as well as αTubulin as loading control. (B) Detection of cytoplasmic and nuclear c-Rel protein by immunoblot. SAM68 and αTubulin revelations are nuclear and cytoplasmic markers, respectively. (C) Percentages of Annexin-V-positive cells gated on NGFRt positive cells. Statistically significant difference (Mann–Whitney test) is indicated by *(p ≤ 0.05).
