wer kann mir sinnerfassend erklären,was in diesem artikel drinnen steht?
verstehe ihn leider nur partiell und es wäre sehr wichtig für mich, den artikel richtig aufzufassen;

How can you determine from FISH results if you have a chromosomal mutation or 'silencing'
of gene expression i.e. epigenetics?
Typically, the FISH test says gain or deletion...I take that to fall under mutation...is that correct? i.e. TP53 present (gain)but malfunctioning
However,
I recently read TP53 function can become compromised for three reasons:
1. 17p deletion where the TP53 gene is broken off and p53 protein production comes to a halt.
2. 17p mutation where the TP53 gene is present but messed up subtly and therefore the p53 protein it makes is also messed up and useless.
3. 17p silencing where the TP53 gene is willing and able to make the right p53 protein but it is covered up with gunk and cannot do its job.
If the FISH results say +TP53...does that mean there is a gain(mutation)...and how would you determine if it is a mutation vs an epigenetic silencing occuring? Or is that distinction possible based on FISH results?
It appears that the DAC agents (pabinostat/vorinostat/ romidepsin) are able to overcome the epigenetic silencing of TP53..and upregulate the activity.
Just curious, how the multiple myeloma experts are viewing this new therapeutic intervention
