Summary
Pregnenolone-16α-carbonitrile (PCN) given orally to rats induces proliferation of the smooth-surfaced endoplasmic reticulum (SER) in hepatocytes, without producing marked alterations in other cell organelles. It appears that this steroid carbonitrile has a similar effect on the liver of hypophysectomized animals. Hypophysectomy alone causes a decrease of the SER.
