Parathyroid hormonelike protein from human renal carcinoma cells. Structural and functional homology with parathyroid hormone. Identification of a novel 17,000-Dalton parathyroid hormone-like adenylate cyclase-stimulating protein from a tumor associated with humoral hypercal-cemia of malignancy. Synthetic human parathyroid hormone-like protein stimulates bone resorp-tion and causes hypercalcemia in rats. The parathyroid hormone-like peptide associated with humoral hypercalcemia of malignancy and parathyroid hormone bind to the same receptor on the plasma membrane of ROS 17/2.8 cells. a causal role of parathyroid hormone-related protein in the pathogenesis of human breast cancer-mediated osteolysis. signaling blockade inhibits PTHrP secretion by breast cancer cells and bone metastases development. hormone-related protein (PTHrP)-(1-139) isoform is efficiently secreted in vitro and enhances breast cancer metastasis to bone in vivo. Structure of the 5Ј flanking region of the gene encoding human parathyroid-hormone-related protein (PTHrP). Identification of an upstream promoter of the human parathyroid hormone-related peptide gene. characterization of a GC-rich promoter of the human parathyroid hormone-related peptide gene. Cell-specific and regulator-induced promoter usage and messenger ribonucleic acid splicing for para-thyroid hormone-related protein. Alternative promoter usage and mRNA splicing pathways for parathyroid hormone-related protein in normal tissues and tumours. reverse transcription-PCR quantification of vascular endothelial growth factor (VEGF) splice variants by LightCycler technology. Activation of PTHrP gene expression in squamous carcinoma cell lines by mutant isoforms of the tumor suppressor p53. Quantification of parathyroid hormone-related protein mRNA by competitive PCR and time-resolved lan-thanide fluorometry. The parathyroid hormone-related protein (PTHrP) gene: use of downstream TATA promotor and PTHrP 1–139 coding pathways in primary breast cancers vary with the occurrence of bone metastasis. Regulation of parathyroid hormone-related protein gene expression in murine keratino-cytes by E1A isoforms: a role for basal promoter and Ets-1 site. factor ␤ regulates parathyroid hormone-related protein expression in MDA-MB-231 breast cancer cells through a novel Smad/Ets synergism. Differential expression of RNA transcripts encoding unique carboxy-terminal sequences of human parathyroid hormone related peptide. regulation of the parathyroid hormone-related peptide gene by glucocorticoids and vitamin D in a human C-cell line. Regulation of parathyroid hormone-related peptide gene expression by cycloheximide. AB, et al. Effect of transforming growth factor-␤1 on parathyroid hormone-related protein secretion and mRNA expression by normal human keratino-cytes in vitro. Quantification of thyrotropin-receptor antibodies is important in the diagnosis and management of patients with Graves disease (1).

The measurement technologies of thyrotropin receptor antibodies from the past to the present

Thyroid Stimulating Hormone Receptor (TSH-R) autoantibodies are the main cause of Graveschr('39') disease and its external thyroid manifestations such as ophtalmopathy and dermatopathy. These antibodies are functionally different and are commonly called TSH receptor antibodies (TRAbs). In fact, TRAbs are a set of autoantibodies including TSHR-stimulating antibodies (TSAbs), TSHR- blocking antib...

Bioassays for TSH Receptor Autoantibodies, from FRTL-5 Cells to TSH Receptor–LH/CG Receptor Chimeras: The Contribution of Leonard D. Kohn

Since the discovery 60 years ago of the "long-acting thyroid stimulator" by Adams and Purves, great progress has been made in the detection of thyroid-stimulating hormone (TSH) receptor (TSHR) autoantibodies (TRAbs) in Graves' disease. Today, commercial assays are available that can detect TRAbs with high accuracy and provide diagnostic and prognostic evaluation of patients with Graves' disease...

A bioluminescence assay for thyrotropin receptor antibodies predicts serum thyroid hormone levels in patients with de novo Graves' disease.

BACKGROUND TSH receptor antibodies (TBII) in Graves' disease (GD) may be TSH receptor stimulating (TSAb) and blocking (TBAb) antibodies. In commercially available assays however, only total TBII titres can be measured, without discriminating between TSAb and TBAb. OBJECTIVE To design a TBII bioassay to detect of TSAb and to correlate TSAb activity with severity of hyperthyroidism in de novo G...

Influence of human anti-mouse antibodies on thyrotropin in-vitro analysis: a comparison of 6 thyrotropin IRMA kits.

OBJECTIVE The aim of the study was to evaluate the influence of human anti-mouse antibodies on the measurement of thyrotropin. INVESTIGATIONS Samples from 11 patients with measureable human anti-mouse antibody titres (19 micrograms/l-3880 micrograms/l) after radioimmuno-scintigraphy were analysed with 6 different thyrotropin immuno-radiometric assay kits (IRMA). Each sample was analysed in th...
