Gene Activation upon Treatment with a Combination of HDAC and EZH2 Inhibitors Is Reversible
(A) Transcript levels of indicated genes were measured by qRT-PCR at the indicated times after removal of the GSK-343/panobinostat drug combination. qRT-PCR values are expressed as mean percentages of vehicle-treated cells ±SEM with B2M serving as internal control. (n = 3).
(B and C) Enrichment of H3K27me3 (B) and H3 acetyl (C) histone marks is measured by ChIP-qPCR at the indicated times after removal of the GSK-343/panobinostat drug combination. qPCR values are expressed as mean fractions of input ±SD.
