The comprehensive literature data and our findings about calcium-regulating hormones participant in the glucose metabolism is analyzed. It is showed calcitonin hyperglycemic effect and its mechanisms, established contra-insulin effect of calcitonin to insulin under the pre-receptor, cell level and liver. It is ascertained the impairment of glucose metabolism under calcitonin hyperglycemia, insu...
Association of receptor activity-modifying proteins (RAMP1-3) with the G protein-coupled receptor (GPCR) calcitonin receptor-like receptor (CLR) enables selective recognition of the peptides calcitonin gene-related peptide (CGRP) and adrenomedullin (AM) that have diverse functions in the cardiovascular and lymphatic systems. How peptides selectively bind GPCR:RAMP complexes is unknown. We repor...
Many G protein-coupled receptors undergo endocytosis, but the mechanisms involved in endocytic sorting and recycling remain to be fully elucidated. We found that the G protein-coupled calcitonin receptor (CTR) undergoes tonic internalization and accumulates within the cell. Using a fluorescence loss in photobleaching assay, we classified these vesicles functionally as recycling vesicles. In a t...
The California bay laurel or Umbellularia californica (Hook. & Arn.) Nutt., is known as the 'headache tree' because the inhalation of its vapours can cause severe headache crises. However, the underlying mechanism of the headache precipitating properties of Umbellularia californica is unknown. The monoterpene ketone umbellulone, the major volatile constituent of the leaves of Umbellularia calif...
Renal tubular targeted hormones increase urinary excretion of a lysosomal enzyme, N-acetyl-beta-D-glucosaminidase (NAG). To elucidate the mechanism of this event, the calcitonin effect on NAG handling by LLC-PK1 cells was examined. Calcitonin (1 nM to 1 microM), phorbol myristate (10 nM to 1 microM), and ionomycin (1 to 10 microM) promoted NAG release without any increase in lactate dehydrogena...
OBJECTIVE The cholecystokinin(2)-receptor (CCK(2)R) promotes secretion and cell growth induced by its ligands cholecystokinin (CCK) and gastrin. The receptor has recently been shown to be expressed in human medullary thyroid carcinomas (MTCs). The objective of this study was to analyze CCK(2)R expression in MTC samples of different tumor stages as well as in non-malignant thyroid tissues. DES...
