Figure 9. Absence of K3K27me3 marks in the Wap-Ramp3 locus in mammary tissue and cerebellum.
(a) H3K27me3 marks were virtually absent in the Wap-Ramp3 locus in mammary tissue from WT and ΔCDE mutants. (b) The Hoxα locus served as a control locus and showed extensive H3K27me3 coverage in mammary tissue. (c) No increase of H3K27me3 marks in ΔE and ΔCDE mutants in the cerebellum. (d) The Hoxα locus served as a control locus in the cerebellum and showed strong H3K27me3 coverage.
