Hi, Brooks,
I'm just getting a chance to revisit this thread. If you still remember writing it, I thought your overall explanation to "damaged" was excellent. And citing that particular text section was helpful too as I will comment on below. I learned from it.
Leaving out all references in your original postings to CYP3A4 would have been the most correct, and yes, substituting "Mevalonate Pathway" would have been correct in that sentence you mentioned right above in this thread. Here's more on how the CYP3A4 system (and other associated stuff) works from what I understand about it:
Normally, only about 5% of the active ingredient in a statin dose/pill like Zocor or Lipitor (other statins may vary) ever hits your blood stream intact. The majority is removed (i.e., metabolized) by the CYP3A4 enzymatic detox system in the liver (and also by certain cells in the gut immediately upon absorption by this same biochemical process as the liver cells use). Most everything we eat, after being absorbed from the gut, goes directly to the liver via its own dedicated short major vessel connecting the two -- rather than into more typical blood vessels that are part of general systemic circulation. (However, just to complicated things, some molecules of the food we eat ARE absorbed directly into general circulation, such as sugars, alcohol and many small molecules. And then some molecules, such as the fats we eat and also cholesterol we eat, I believe, are actually absorbed from the gut into the lymphatic system -- largely comprised of white blood cells, not red -- and take a longer route through that circulatory system to eventually get dumped into general systemic circulation where the lymphatic system connects with the general circulation system near the heart). Fun, huh...
However, it the CYP3A4 system is inhibited from working in liver and gut cells, then much more than 5% of the statin slips by intact into the blood of the general circulation after exiting the liver. And that is where major problems occure!! (Grapefruit juice has a chemical that inhibits this system too, and most of us have heard of that particular "drug interaction.") This huge amount of active statin in the general circulation REALLY stops the Mevalonate pathway in its tracks bigtime. Everywhere. Very little cholesterol and CoQ10 and other stuff is able to be made in our cells -- and primarily in our liver cells for export throughout the body. Production is all blocked by the huge amount of active statin! At that point Major Damage then instantly occurs to cells, tissues and organs everywhere in the body, rather than just by the slow deterioration common to chronic statinization (as we all know very well).
Your cited text mentioned Vitamin E being carted around by LDL. It is my understanding that it partly rides on the OUTSIDE of the LDL carrier complex rather than just inside with the cholesterol and fatty acids, and this is what gives LDL some of its antioxidant qualities. Vitamin E is a mean free radical buster.
