Research Interests: molecular endocrinology; mechanism of hormone and growth factor signal transduction.

The endocrine research program in Dr. Hughes' laboratory is concerned with understanding of the mechanisms whereby receptors mediate the actions of prolactin, growth hormone, and interleukin-2. Part of Dr. Hughes' research involves identification of the cellular events which follow activation of the receptors for prolactin and interleukin-2 in T lymphocytes, and the immunoregulatory role of prolactin. The lab is also studying the protein stathmin (also called Op18) and related proteins, changes in stathmin in response to various growth factors, identification of stathmin-binding proteins, and the range of stathmin occurrence in the animal and plant kingdoms.hughes2.jpg
