In contrast, and in agreement with the normal expression of CCND1 and DAPK1 in XP-CMUT cells compared to XP-CWT cells (Fig. 1f), the deposition of H3K9ac and H3K4me3 on the promoter of these genes was not modified in XP-CMUT cells (Fig. 2d and Supplementary Figure 1F, lower panels). The gene discussed is CCND1; the disease is xeroderma pigmentosum.
