Dear All,
I have the following alleles in P450 CYPs :
CYP1A1 C2453A rs1799814 GT +/-
CYP1A2 164A>C rs762551 AC +/-
CYP1B1 L432V rs1056836 GG +/+
CYP2C19*17 rs12248560 CT +/-
CYP2D6 S486T rs1135840 GG +/+
CYP2D6 100C>T rs1065852 AA +/+
GSTP1 I105V rs1695 AG +/-
NAT2 I114T rs1801280 CT +/-
NAT2 K268R rs1208 AG +/-
Perhaps the worst is CYP7B1 :
with a 2.7% Frequency. Note that the second version is ok.
CYPs are essentially the P450 System that i discuss at the beginning of this post (talking especially about P450scc).
So what i wanted to say is that almost everything that we discuss here : Oxidation/Reduction, FAD, Cofactors..they have to do with Phase I and Phase II functioning of the liver.
Now i am not certain for what i am saying, i do not have the knowledge as i am not a medical professional but you can check this out as well.
All i know is that i was feeling really bad when unknowingly i would take P450 Inhibitors (hence the entry on my first post). Of course you could try it but i'd rather prefer that you do not try such thing.

You discuss about feeling better with DHEA. My hypothesis is that the reason is this :
Dehydroepiandrosterone (DHEA), the major precursor of androgens and estrogens, has several beneficial effects on the immune system, on memory function, and in modulating the effects of diabetes, obesity, and chemical carcinogenesis. Treatment of rats with DHEA influences expression of cytochrome P450 (P450) genes, including peroxisome proliferator-activated receptor α (PPARα)- and pregnane X receptor (PXR)-mediated induction of CYP4As and CYP3A23, and suppression of CYP2C11. DHEA treatment elevated the expression and activities of CYP3A4, CYP2C9, CYP2C19, and CYP2B6 in primary cultures of human hepatocytes. Induction of CYP3A4 in human hepatocytes was consistent with studies in rats, but induction of CYP2Cs was unexpected.
Again, the hypothesis is that Liver Function is very much involved in CFS/PFS/Accutane symptoms. It is NOT the immune system (as the basis of our problems)
Continuing my hypothesis, it goes like this : I think that it is extremely unlikely that someone -assuming he has impaired Liver function- will feel better just by using cofactors in order to handle Redox homeostasis.
If we have an impaired Liver, then we need to stop further Liver damage by using agents such as TUDCA and Choline (?) and at the same time use cofactors to stop Oxidative Stress.
I am in my 4th day of not using TUDCA, time will tell.
