We concurrently performed cell cycle analysis of cells treated with vehicle or VX702 and found a marginal accumulation in the S-phase (Supplementary Fig. 4b), however, with a significantly reduced BrdU incorporation (Supplementary Fig. 4c), demonstrating a reduced S-phase efficiency and prolonged cell cycle length following p38 inhibition in DLBCL. This evidence concerns the gene MAPK1 and diffuse large B-cell lymphoma.
