Fig. 3. CDK6 inhibition by palbociclib synergizes with IMiD treatment of multiple myeloma cells.
A Cell viability of MM.1S cells treated 96 h with pomalidomide (pom), palbociclib (palb), or in combination. (N = 3 biologically independent replicates). B Synergy map of MM.1S cells treated with palbociclib in combination with lenalidomide or pomalidomide. C Cell viability of L363 cells treated with pomalidomide, palbociclib, or in combination (N = 3 biologically independent replicates). D Synergy map of L363 cells treated with palbociclib in combination with lenalidomide or pomalidomide. E Cell viability of MM.1S LenR cells (N = 3 biologically independent replicates) and F OPM2 CDK6 OE cells upon combination treatment of pomalidomide and palbociclib (N = 3 biologically independent replicates) Synergy levels are indicated with ZIP synergy scores. Synergy maps were generated with SynergyFinder75. Cell viability is normalized to respective DMSO conditions. Data represent the mean ± SD of biological triplicates. One-way ANOVA is applied. P values are displayed as follows: n.s. = P > 0.05; *P ≤ 0.05; **P ≤ 0.01; ***P ≤ 0.001; ****P ≤ 0.0001. Source data are provided as a Source Data file.
