Cholesterol steroid pathway

There are no tell, tell signs of steroid abuse like there are with recreational drugs and this can make true abuse a little difficult to spot. However, here at we want to look at all aspects of steroid use, and in doing so, give you a better understanding of the topic at hand. Some of what you find will be nothing new, but much of it promises to be information that you’ve never been told. There is so much to discuss when it comes to this topic, and we guarantee when it comes to steroid abuse you may very well find what you once believed will rapidly change once exposed to the truth.

From a dietary perspective, plant cells do not manufacture cholesterol, and it is not found in plant foods. [30] [32] Some plant foods, such as avocado , flax seeds and peanuts , contain phytosterols , which compete with cholesterol for absorption in the intestines, reducing the absorption of both dietary and bile cholesterol. [33] However, a typical diet contributes on the order of grams of phytosterols, which is not enough to have a significant impact on blocking cholesterol absorption. Phytosterols intake can be supplemented through the use of phytosterol-containing functional foods or dietary supplements that are recognized as having potential to reduce levels of LDL -cholesterol. [34] Some supplemental guidelines have recommended doses of phytosterols in the – grams per day range (Health Canada, EFSA, ATP III, FDA). A recent meta-analysis demonstrating a 12% reduction in LDL-cholesterol at a mean dose of  grams per day. [35] However, the benefits of a diet supplemented with phytosterols have been questioned. [36]

Bile acids, in particular chenodeoxycholic acid (CDCA) and cholic acid (CA), can regulate the expression of genes involved in their synthesis, thereby, creating a feed-back loop. The elucidation of this regulatory pathway came about as a consequence of the isolation of a class of receptors called the farnesoid X receptors, FXRs . The FXRs belong to the superfamily of nuclear receptors that includes the steroid/thyroid hormone receptor family as well as the liver X receptors (LXRs) , retinoid X receptors (RXRs), and the peroxisome proliferator-activated receptors (PPARs) .
