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 somatotropes.  We have received National Institute of Health and National Science Foundation funding and are currently supported by R01 HD059056-05

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)
  • Significance and regulation of anterior pituitary leptin 
  • Significance of leptin receptors on pituitary somatotropes and gonadotropes.

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. (completed Ph.D. in 2006)
  • Chris Crane, M.S. (Master's program; Honors Medical Student; Completed MD in 2010
  • Zachary Brodrick, M.S. (MS, completed in 2008, MD Completed in 2013).
  • Angela Odle, Ph.D. (Ph.D. Completed in 2014)
  • Melody Allensworth (Ph.D. Program, 2011-present)

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.
