The calcitonin receptor (CTR) is a class B G protein-coupled receptor that is a therapeutic target for the treatment of hypercalcaemia of malignancy, Paget's disease and osteoporosis.
We suggest for the first time a protective role against osteoporosis in GD1 patients for the CC genotype of the c.9C>G gene variant in the TNFRSFB11 (OPG) gene and for the CC genotype of the c.1340T>C gene variant (CALCR gene), while the AA genotype of the c.1024+283G>A gene variant in the VDR gene appears as a risk factor for lower BMDs.
The C1377T polymorphism in the CTR gene is associated with BMD at the lumbar spine in a postmenopausal Han Chinese population and the CTR gene may become a useful genetic marker for predicting the risk of developing osteoporosis in postmenopausal Chinese women.
In the combined genotype analysis, ER1/CALCR TCCC combined genotype was estimated to have protective effect against osteoporosis [p=0.0125, OR=0.323, 95% CI (0.1383-0.755)] whereas BGLAP/Col1A1 CCTT and ER1/CALCR CCTT combined genotypes were estimated as risk factors for osteoporosis in Turkish population (p=0.027, p=0.009 respectively).
Association analyses and multivariate two-step regression model of social and molecular parameters, demonstrated that in comparison to the VDR, ESR, CTR polymorphisms, physical activities and healthy diet, associated with outdoor work are the best favourable prognostic factors for osteoporosis.
Our aim was to evaluate the correlation of the ALUI calcitonin receptor gene polymorphism to bone mineral density and their relationship to osteoporosis.
In conclusion, the polymorphism of CTR gene but not VDR and COLIA1 is associated with osteoporosis incidence and the levels of alkaline phosphatase and estradiol.
Calcitonin receptor mRNA in mononuclear leucocytes from postmenopausal women: decrease during osteoporosis and link to bone markers with specific isoform involvement.
The effects of CT on the physiology of a variety of organ systems are discussed and the relationship between polymorphisms in the CTR gene and bone mineral density (BMD)/osteoporosis is examined.
