MORE ABOUT 5-AZACITIDINE
Be careful though, when you give an hypomethylating agent, do not expect that the agent is de-methylating everywhere, some molecule end up being methylated, this is called Reverse Methylation. There seem to me a random (or not) reorganization of the methylation.
Moreau
"Exposure of cells to histone deacetylase
inhibitors, or
to the demethylating agent
5-aza-2′-deoxycytidine, revealed that HLA-G gene transcription is
inhibited by DNA methylation.
Reversal of methylation-mediated
repression may directly induce HLA-G cell-surface expression, supporting
the idea that HLA-G
might be activated by such a mechanism
during malignancy, inflammation, and allogenic reactions"
what is the meaning of this
is this point to limitation of this drug activity
should we be checking for HLA-G
more work is ahead I guess!
