Steroid hormones are required by the body at puberty and into adolescence to regulate growth and cell division at more rapid pace than in later life.  This regulation occurs via their interaction with cellular receptors and the signaling cascades/pathways that follow.  Describe for me the difference between the two major classes of steroids, anabolic and catabolic steroids.  What might you expect the result of signaling cascades to be in cells receiving either anabolic or catabolic “signals”? (B) At some point in late adolescence, steroid production decreases by almost 100 fold, as we transition into “adulthood”.  Why might we wish to stop these signals from constantly being in our blood stream, (like, Say, between 17-24 years of age)?  What result might these steroids have on cancer cells where abhorrent signaling is already causing an increased rate of cell division/growth? Could steroid use result in Cancer?
