(A) Shows that no mRNA is induced in the absence of 5-AZA-C. Control stands for myeloid cells expressing the CRISPR activator protein (CAS9-SAM) but no guide RNA. Sg1, Sg2, and Sg3 refer to different guides directed to three different locations in the promoter. The significance of the increase in Kit mRNA levels, Plus 5-AZA-C, in Sg1 over control: p < 0.011, in Sg2 over control: p < 0.028, in Sg3 over control: p < 0.02. (B) And (C) are ChIP-qPCR experiments probing for H3K27me3 along the Kit promoter in the absence of any guide RNA (gray line), and the bluish line guide 3.
