A neurohypophyseal hormone analog with selective oxytocin-like activities and resistance to enzymatic inactivation: an approach to the design of peptide drugs.

abstract：:Bone remodeling requires osteoclasts to generate and maintain an acidified resorption compartment between the apical membrane and the bone surface to solubilize hydroxyapatite crystals within the bone matrix. This acidification process requires (i) apical proton secretion by a vacuolar H(+)-ATPase, (ii) actin cytoskel...
