The research in my laboratory  is focused on the regulation of specific anterior pituitary cells by neuroendocrine peptides and growth factors. Most recently, we are focused on the role of leptin in the regulation of pituitary gonadotropes and growth hormone.  We have received National Institute of Health and National Science Foundation funding.  (Formerly Gwen C. Moriarty, Ph.D.)

Specific Projects

Dynamic changes in gonadotropes during the reproductive cycle.
 Are growth hormone cells co-gonadotropes?
 The effects of epidermal growth factor on pituitary corticotropes and  gonadotropes.
 The effects of stress on the expression of pituitary epidermal growth factor .
 Regulation and secretion of pituitary nerve growth factor
 Stimulus secretion coupling in corticotropes: role of ion channels in signaling
Significance and regulation of Anterior pituitary leptin to the reproductive system (page under construction)
Regulation of monohormonal gonadotropes, expressing only one beta subunit mRNA (page under construction)

 Graduate students 1994-present

 James Patterson (M.D. Ph.D. student; completed Ph.D in 1994) Now doing a residency in Psychiatry at the University of Texas Medical Branch.
  Xuemo Fan (completed Ph.D. in 1994)
  Jennifer Armstrong (completed Ph.D. in 1997)
  Jiangang Xie (completed Ph.D. in 1998)
Iris MacDuffie (M.S. student in Nutrition at UAMS)
Mary  Iruthayanathan, M.D. (Ph.D. student in Anatomy and Neurobiology) 
Chris Crane, M.S. (Master's program); now an Honors Medical Student

Special techniques used in laboratory

  Immunogold cytochemistry for detection of hormones and growth factors
  Affinity Cytochemistry for detection of receptors
  In situ hybridization to detect messenger RNA
  Dual labeling for detection of receptors or mRNA and antigens (or two antigens)
  Centrifugal elutriation to enrich and purify pituitary corticotropes gonadotropes, and growth hormone cells.
siRNA silencing of pituitary leptin.  Transfection of primary pituitary cell cultures
Cre-loxP technology applied to selectively knockout genes in gonadotropes or somatotropes.  Deletion mutants of leptin receptors are now being produced.

We also use more routine technology like electron microscopy, cytology, radioimmunoassay, image analysis, enzyme immunoassay, and tissue culture. Most molecular biology techniques such as qRT-PCR, RNA and DNA extraction, genotyping are ongoing in core facilities,
