Research Abstract

An increasing number of transcription factors and nuclear receptors are reported to regulate cell type differentiation. This study was aimed to clarify the role of transcription factors, nuclear receptors and hypothalamic hormone receptors in cell type differentiation and cell proliferation in the anterior pituitary and pituitary adenomas. In the human pituitary adenomas, Pit-1 was highly expressed in GH and TSH adenomas. Interestingly, non-functioning pituitary adenomas which express alpha subunit also expressed Pit-1. Using RT-PCR method, Ptx-1 and Neuro D1 were expressed in all types of adenomas. These results may suggest that those two factors are universal transcription factors in pituitary. Estrogen receptor was highly expressed in PRL and gonadotroph adenomas. As for hypothalamic hormone receptors, we investigated TRHR and GH secretagogue (GHS)R expression. GHSR was expressed in all types of adenomas with the highest level in GH-secreting adenomas. Ghrelin, an endogenous ligand for GHSR was expressed in all types of adenomas with the highest level in non-functioning adenomas. From those results, it was suggested that hypothalamic hormones may have an autocrine and paracrine effect in anterior pituitary.
