BACKGROUND Hyperparathyroidism is a common endocrinopathy characterised by the formation of parathyroid tumours. In this study, we determine the role of the recently identified gene, HRPT2, in parathyroid tumorigenesis. METHODS Mutation analysis of HRPT2 was undertaken in 60 parathyroid tumours: five HPT-JT, three FIHP, three MEN 1, one MEN 2A, 25 sporadic adenomas, 17 hyperplastic glands, tw...
A novel factor, named crustacean hematopoietic factor (CHF), was identified from a library of suppression subtractive hybridization with the aim to find downstream genes of an invertebrate cytokine, astakine 1, in the freshwater crayfish Pacifastacus leniusculus. CHF is a small cysteine-rich protein (∼9 kDa) with high similarity to the N-terminal region of vertebrate CRIM1 in containing an insu...
CDC73 (HRPT2) germline mutations are responsible for more than half of cases of hyperparathyroidism-jaw tumor syndrome (HPT-JT) and for a subset of familial isolated HPT (FIHP). We performed a clinical, genetic, and histopathologic study in three unrelated Italian kindreds with HPT-JT and FIHP. We identified three germline inactivating mutations of the CDC73 gene in the probands and affected pa...
In the process of sequencing the region of Vibrio harveyi DNA containing the luxR gene (1), which encodes an activator of luminescence gene transcription, another large open reading frame was also sequenced. This coding region is 528 base pairs in length, is located immediately upstream from the luxR gene and is transcribed in the opposite direction (fig. 1). The deduced 176 amino acid sequence...
Two-component signal transduction (TCST) pathways play crucial roles in many cellular functions such as stress responses, biofilm formation, and sporulation. The histidine phosphotransferase (HPt), which is an intermediate phosphotransfer protein in a two-component system, transfers a phosphate group to a phosphorylatable aspartate residue in the target protein(s), and up-regulates stress-activ...
BACKGROUND Primary hyperparathyroidism (HPT) is a common cause of urolithiasis. Only a few data are available on stone composition and morphology in HPT patients. METHODS We compared the composition and morphology of stones from 264 HPT patients (143 males and 121 females) and 24 567 non-HPT stone formers (16 918 males and 7649 females) including a subgroup of 1356 patients with idiopathic hy...
Introduction: To report two unusual cases of primary hyperparathyroidism (HPT) that initially manifested with a “ jaw tumor” and to discuss the clinical implications of a giant cell granuloma vs an ossifying fibroma of the jaw. Material and methods: The history, physical examination, laboratory values and the imaging and pathologic findings are described in two patients who presented with a “ja...
The majority of soybeans planted in the United States are resistant to glyphosate due to introduction of a gene encoding for a glyphosate-insensitive 5-enolypyruvylshikimate-3-phosphate synthase. Gene expression profiling was conducted using cDNA microarrays to address questions related to potential secondary effects of glyphosate. When glyphosate-sensitive plants were treated with glyphosate, ...
Improved diagnosis of psoriasis, by new biomarkers, is required for evaluating the progression rate of the disease and the response to treatment. Haptoglobin (Hpt), a glycoprotein secreted by hepatocytes and other types of cells including keratinocytes, was found with glycan changes in psoriasis and other diseases. We previously reported that Hpt isolated from plasma of psoriatic patients is mo...
PURPOSE A reliable method for diagnosing parathyroid carcinoma has remained elusive over the years, resulting in its under-recognition and suboptimal therapy. Obtaining an accurate diagnosis has become an even more pressing matter with recent evidence that germline HRPT2 gene mutations are found in patients with apparently sporadic parathyroid carcinoma. There is a high prevalence of HRPT2 gene...
