DMP1 and hypoparathyroidism: Using the 9.6 kB DMP1‐Cre deleter strain,25 PTH receptor deletion causes mild increases in bone mass associated with reduced bone resorption,26 a phenotype reminiscent of what is observed in humans with hypoparathyroidism.27 Importantly, a similar low bone turnover phenotype in 8 kB DMP1‐Cre PTH receptor null mice is observed.28 Mice with osteocytes lacking PTH receptors have been used to ascertain the role of the osteocytic PTH receptor signaling in skeletal responses to intermittent and continuous PTH treatment.
