Figure 6. Myogenesis hypomethylated sites in MYH7B/MIR499 over an exon whose inclusion triggers nonsense-mediated decay of mRNA. DNA and chromatin epigenetic marks are indicated as in the previous figures for half of the exons of MYH7B (exons 1–23) and the 5′ end of GSS (chr20:33,542,729–33,578,756). An expanded view of exons 10–18 (chr20:33,570,058–33,575,875) is shown at the bottom of the figure. The representative cell strains and tissues illustrated are as follows: IBM Mb, Ctl Mb3, Ctl Mt3, Ctl Mb7, Ctl Mt7, LCL, Fib1, HMEC, ESC, Muscle A1, Muscle A2, Muscle B1, Muscle B2, leukocyte, kidney, brain, stomach and cardiac muscle. DHS and CTCF peaks that were specific to Mb and Mt are boxed in purple.
