The information about receptor regulation are about breast cancer cells, but it is relevant because they sensitize these receptors so cancer fighting drugs can bind to cells then be more effective. (explained in many of the sources) It is extremely rare, if not unavailable to find a study on chemicals' regulation effects on healthy cells. Other research I look at is about healthy cells, and herbs that inhibit cancer.

This is the point about receptor regulation

the receptor control theory postulates that our set points for regulating weight, energy, or pleasure are variable; they are directly related to the number, sensitivity and location of cellular receptors in our bodies, and can be modified by changing the number and sensitivity of these receptors.
