We have already demonstrated the inhibitory effect of interleukin 1 on thyroglobulin gene expression. Recent availability of thyroid peroxidase cDNA has allowed us to investigate the regulation of thyroid peroxidase gene. Therefore, the regulation of thyroid peroxidase mRNA by interleukin 1 in cultured human thyrocytes was investigated. Thyrocytes dispersed(More)
We have previously demonstrated that interferon-gamma (IFN-gamma) induced HLA-DR antigen and also inhibited thyrotropin (TSH)-induced triiodothyronine (T3) and thyroglobulin (Tg) secretion from cultured human thyrocytes. In order to further clarify the inhibitory effect of IFN-gamma on TSH-stimulated thyroid hormone secretion, we have examined human thyroid(More)
We examined aspects of the mechanism of desensitization of adenylate cyclase activation by TSH in a cloned line of rat thyroid cells (FRTL). Increasing FRTL intracellular cAMP concentrations by preincubation for 6 h in either 1 mM dBcAMP or 100 microM forskolin did not induce TSH desensitization. Forskolin stimulation was unimpaired in TSH-desensitized(More)
The thyroid microsomal antigen (MSA) in autoimmune thyroid disease is a protein of approximately 107 kD. We screened a human thyroid cDNA library constructed in the expression vector lambda gt11 with anti-107-kD monoclonal antibodies. Of five clones obtained, the recombinant beta-galactosidase fusion protein from one clone (PM-5) was confirmed to react with(More)
cDNAs for thyroid peroxidase (TPO) and thyroglobulin (Tg) have been cloned and sequenced. Using such cDNAs, we investigated the regulation of TPO and Tg gene expression by various agents in cultured human thyroid cells. Unstimulated human thyroid cells contained a major RNA species [3.2 kilobases (kb) in length] and several minor RNA species (less than 3.2(More)
The regulation of thyroglobulin (Tg) and its specific mRNA by interleukin-1 (IL-1) in cultured human thyrocytes was investigated. Specific binding of 125I-labelled IL-1 on thyrocytes was confirmed by solid-phase binding assay. Thyrocytes dispersed from Graves' thyroid tissues were incubated with TSH with or without recombinant human IL-1. TSH stimulated Tg(More)
Insulin-like growth factor-1 (IGF-1) is synthesized primarily by the liver in response to growth hormone (GH). Thyroid hormone plays a major role in mediating pituitary GH secretion. In order to clarify the effect of thyroid hormone on IGF-1 gene expression, we measured hepatic IGF-1 mRNA levels in rats with thyroid dysfunction. Female Wistar rats were(More)
In this paper, we propose a robust method to register a panoramic range data obtained by a panoramic laser range finder and an omni-directional image acquired by a stereo omni-directional system (SOS), by matching the horizontal and vertical edge histograms of the two images. The proposed method first estimates the relative horizontal rotation angle by(More)
