AZA treatment induces the genes but bisulfite sequencing does not reveal de-meth - (Jan/27/2014 )

Thanks a lot. If possible, can you share a link of your publication please?

This one.

β-Thalassemia Due to Intronic LINE-1 Insertion in the β-Globin Gene (HBB): Molecular Mechanisms Underlying Reduced Transcript Levels of the β-GlobinL1 Allele

It's only a brief report though, so there wasn't much space to discuss it, but it cites this paper, that originally showed that AZA is not the cause of increased expression of gamma-globin (which is silenced by hypermethylation in adults):
