"Epi">>reversible
definition : modifications on DNA /histones
- alter the DNA sequence
- Tumorigenesis : cancer --> expression / regulation change
factor
- DNA methylation
-
- DNA methylase (DMNT)
- effect
-
- imprinting : transfer certain environmental factor
- X-chromosome inactivation
- Heterochromatin maintenance
- Developmental controls
- Tissue specific expression controls
- How to sequence methylation?
-
- Biosulfite treatment of cytosine : cytosine --> uracil ( 5-methylcytosine residues is unaffected)
