Histone acetylation in DLBCL lines after treatment with panobinostat and decitabine. (A) Immunofluorescence analysis of H3 acetylation in Ly1 and Ly10 lines after treatment with panobinostat and decitabine alone or their combination for 24 hours. The same exposure times reveal increased H3 acetylation in the combination group. (B) Western blot analysis of the H3 acetylation after treatment with panobinostat and decitabine alone or their combination in Ly1 and Ly10 lines at 2 time points (24 and 48 hours).
