Characterization of Prophet of Pit-1 gene expression in normal pituitary and pituitary adenomas in humans.
Prophet of Pit-1 (Prop-1), which is a paired-like homeodomain transcription factor, is capable of binding to sites in an early enhancer of the Pit-1 gene and regulating its expression. According to a previous report, Prop-1 messenger RNA (mRNA) is expressed in the developing pituitary gland before Pit-1 mRNA expression and maximum expression are observed at e 12.0. After e 14.5, Prop-1 mRNA exp...
متن کاملDNA ploidy and cell phase in human pituitary tumors.
The flow-cytofluorometric technique for nuclear DNA analysis was used in the study of 47 consecutive cases with pituitary tumors. The material consisted of 18 tumors secreting growth hormone (GH), 10 secreting GH and prolactin (PRL), 10 prolactinomas, 2 secreting thyroid-stimulating hormone (TSH), 2 secreting ACTH, and 5 were nonsecreting. An aneuploid DNA pattern occurred in 23 of 47 (49%) cas...
متن کاملAnterior pituitary cell networks
Both endocrine and non-endocrine cells of the pituitary gland are organized into structural and functional networks which are formed during embryonic development but which may be modified throughout life. Structural mapping of the various endocrine cell types has highlighted the existence of distinct network motifs and relationships with the vasculature which may relate to temporal differences ...
متن کاملRET receptor expression in thyroid follicular epithelial cell-derived tumors.
The RET proto-oncogene encodes a receptor tyrosine kinase for transforming growth factor-beta-related neurotrophic factors, which include GDNF and neurturin. The expression of RET proto-oncogene was detected in several tissues, such as spleen, thymus, lymph nodes, salivary gland, and spinal cord, and in several neural crest-derived cell lines. RET expression in the thyroid gland was reported to...
متن کاملComparison of two isozymes of carbonic anhydrase in the rat anterior pituitary gland and pituitary tumors.
Two isozymes of carbonic anhydrase (EC 4.2.1.1.) were compared in the anterior pituitary gland of non-tumor-bearing rats and in the hormone-secreting pituitary tumors. In contrast to the pituitary gland, which contained 60 to 70% of the total carbonic anhydrase in the particulate subcellular fraction, three hormone-secreting pituitary tumors were devoid of the particulate (Triton X-100-solubili...
