Figure 2 | Transcriptional repression of Bim and BMF genes by <t>RelB-p52.</t> (a,b) Total RNA from JJN3 cells infected with lentiviruses expressing Control-Sh RNA or sh-RNAs targeting RelB or NF-kB2 was analysed by qRT–PCR for the expression of Bim and BMF. (c,d) Whole cell lysates from JJN3 cells and Bortezomib resistant RPMI-8226 cells infected with lentiviruses expressing the indicated sh-RNAs, were analysed for the indicated proteins by immunoblotting. (e,f) Recruitment of RelB and p52 to the endogenous Bim and BMF promoters. Chromatin from JJN3 cells was immunoprecipitated using a-RelB or a-p52 antibodies. <t>Normal</t> <t>IgG</t> was used as a control. Recruitment of RelB and p52 to the Bim (e) and BMF (f) promoters was analysed by PCR- amplification of the immunoprecipitated DNA using specific primers that amplified a 154-bp region ( 300 to 146) close to the Bim gene transcriptional start site and a 160-bp region ( 164 to 4) proximal to the BMF transcriptional start site. As a control, a region spanning 2476 to 2201 of the Bim promoter was also amplified using primers specific to this region (e lower panel). Amplified PCR products were analysed by running on agarose gels as indicated. Note that RelB-p52 were recruited specifically to a site that is 300 bp upstream but not to a region that is 2.4-kb upstream to the Bim transcriptional start site. (g) Combined depletion of Bim and BMF rescues RelB-depleted cells from apoptosis. JJN3 cells were infected with lentiviruses expressing control Sh-RNA or Sh-RNAs targeting Bim and BMF and were selected in puromycin prior to silencing RelB. Apoptosis was measured as explained above. Note the significant rescue from apoptosis of RelB-silenced cells in the absence of Bim and BMF. Error bars indicate s.d. n ¼ 3. Representative figures from —three to five experimental replicates are shown.

Schematic of how BET-mediated ROS production sensitizes PCa cells toward death caused by RT while protecting non-PCa cells against injury from RT off-target effects. Aberrant redox homeostasis of cancer cells enables redox-modifying agent BET to enhance radiation therapy efficacy by selective sensitization. In normal cells under physiologic conditions, cellular redox status is kept at a low oxidizing level. A shift in cell redox status toward an oxidizing condition, from BET + RT, will stimulate the expression of RelB-BLNK and translocation to the nucleus, which leads to upregulation of the antioxidant system, including MnSOD. The upregulation of MnSOD maintains redox status in normal cells and promotes cell survival. To the contrary, cancer cells are usually under high oxidizing conditions. A comparable shift in ROS levels modulated by BET + RT to an extreme oxidizing condition will cause cell death. Green arrows = activation; Red line = inhibition.

Figure 2 | Transcriptional repression of Bim and BMF genes by RelB-p52. (a,b) Total RNA from JJN3 cells infected with lentiviruses expressing Control-Sh RNA or sh-RNAs targeting RelB or NF-kB2 was analysed by qRT–PCR for the expression of Bim and BMF. (c,d) Whole cell lysates from JJN3 cells and Bortezomib resistant RPMI-8226 cells infected with lentiviruses expressing the indicated sh-RNAs, were analysed for the indicated proteins by immunoblotting. (e,f) Recruitment of RelB and p52 to the endogenous Bim and BMF promoters. Chromatin from JJN3 cells was immunoprecipitated using a-RelB or a-p52 antibodies. Normal IgG was used as a control. Recruitment of RelB and p52 to the Bim (e) and BMF (f) promoters was analysed by PCR- amplification of the immunoprecipitated DNA using specific primers that amplified a 154-bp region ( 300 to 146) close to the Bim gene transcriptional start site and a 160-bp region ( 164 to 4) proximal to the BMF transcriptional start site. As a control, a region spanning 2476 to 2201 of the Bim promoter was also amplified using primers specific to this region (e lower panel). Amplified PCR products were analysed by running on agarose gels as indicated. Note that RelB-p52 were recruited specifically to a site that is 300 bp upstream but not to a region that is 2.4-kb upstream to the Bim transcriptional start site. (g) Combined depletion of Bim and BMF rescues RelB-depleted cells from apoptosis. JJN3 cells were infected with lentiviruses expressing control Sh-RNA or Sh-RNAs targeting Bim and BMF and were selected in puromycin prior to silencing RelB. Apoptosis was measured as explained above. Note the significant rescue from apoptosis of RelB-silenced cells in the absence of Bim and BMF. Error bars indicate s.d. n ¼ 3. Representative figures from —three to five experimental replicates are shown.

Figure 4 | RelB recruits HDAC4 and maintains repressive chromatin on Bim and BMF promters. Chromatin from control or RelB-depleted JJN3 cells was immunoprecipitrated with a-HDAC4, a-Acetyl H3 or normal IgG antibodies. Recruitment of HDAC4 to the BMF (a) and Bim (b) promoters (a and b left and middle panels) was analysed by PCR-amplification of the immunoprecipitated DNA using specific primers corresponding to BMF and Bim promoters. Note the loss of HDAC4 recruitment in the absence of RelB. Acetylation of Histone H3 on BMF and Bim promoters was analysed by ChIP assay using a-acetyl H3 antibody and PCR-amplification of immunoprecipitated DNA as explained above (a and b right panels). (c) Increased expression of proapoptotic Bim and BMF genes on HDAC4 depletion. Total RNA from JJN3 cells infected with lentiviruses expressing Control-Sh RNA or sh-RNA targeting HDAC4, was analysed by quantitative PCR for the expression of Bim and BMF and relative expression was plotted as indicated. (d) Increase in proapoptotic Bim but not BMF protein levels on HDAC4 depletion. Whole cell lysates from JJN3 cells infected with lentiviruses expressing indicated sh-RNAs, were analysed for the indicated proteins by immunoblotting. Note the elevation of Bim but not BMF protein levels on depletion of HDAC4. (e) RelB-p52 regulation of miR-221 in MM cells. RNA from JJN3 cells infected with lentiviruses expressing Control-sh RNA or sh-RNAs targeting RelB, NF- kB2 or HDAC4 were analysed by quantitative PCR for miR-221 expression. Note the down regulation of miR-221 on RelB or NF-kB2 depletion but not on HDAC4-depletion. (f) Exogenous miR-221 prevents elevation of BMF protein levels in RelB-depleted cells. JJN3 cells infected with control or miR-221 expressing lentiviruses were superinfected with lentiviruses expressing control-Sh RNA or sh-RNA targeting RelB. Whole cell lysates were analysed by immunoblotting for the indicated proteins. Note the elevation of Bim protein levels in RelB depleted cells in both control and miR-221 overexpressing cells, whereas BMF protein levels were increased only in RelB depleted control but not in miR-221 over expressing cells. *non-specific band.

Figure 8 | A Model that integrates HDAC4, p52, RelB and ERK1 into MM cell survival. (a) A novel HDAC4–RelB–p52 complex is frequently formed in MM cells that maintains deacetylated state of histones around Bim and BMF loci leading to transcriptional repression of both Bim and BMF genes and promotes MM cell survival. (b) Disruption of RelB–HDAC4 complex by a HDAC4-mimetic-peptide results in impaired repression of Bim and BMF loci leading to enhanced expression of Bim and BMF and apoptosis of MM cells. (c) RelB-p52 repress BMF in a two-step mechanism: 1) Transcriptional repression of BMF promoter by the HDAC4–RelB–p52 complex that maintains deacetylated state of histones and 2) Regulation of miR-221 expression by RelB-p52. RelB-p52 induced expression of miR-221 will further repress the BMF by impairing the translation of BMF mRNA. (d) ERK1 is a novel RelB-kinase. In MM cells RelB and ERK1 constitutively interact with each other. ERK1 is constitutively in an active form that phosphorylates RelB leading to nuclear accumulation of phospho-RelB and phospho-RelB dependent repression of Bim promoter. ERK1 might phosphorylate RelB in the cytoplasm, nucleus or on the promoter itself. Specific inhibition of ERK1 is sufficient to block RelB-phosphorylation leading to enhanced Bim expression and MM cell apoptosis.
