Protein and polypeptide hormones as inhibitors.

It is becoming increasingly apparent that hormones regulate morphogenetic processes and metabolic reactions through inhibitory mechanisms as well as stimulatory effects. Inhibition by protein and polypeptide hormones and the numerous analogs that have been prepared, was discussed in a recent article (1). The present brief review is concerned with more recent developments in this field, including the role of protein and polypeptide hormones in the control of cell proliferation and differentiation.
