Parathyroid hormone-related peptide delays terminal differentiation of chondrocytes during endochondral bone development.
To test the hypothesis that PTH-related peptide (PTHrP) is a paracrine regulator of endochondral bone development, we localized PTHrP and its cognate receptor during normal skeletal development at… Expand

A variety of solid tumors secrete proteins that are immunochemically distinct from parathyroid hormone (PTH) but activate PTH-responsive adenylate cyclase. Such PTH-like proteins have been proposed… Expand

RANKL and OPG gene expressions were measured with and without PTH at different stages of osteoblast development. Mouse stromal cells were cultured in osteoblast differentiating conditions, and RANKL,… Expand
Increased serum levels of a parathyroid hormone-like protein in malignancy-associated hypercalcemia.
STUDY OBJECTIVE To measure the serum levels of a newly described parathyroid hormone-like protein (PLP) which was isolated from malignant tumors associated with hypercalcemia, and determine whether… Expand
Engineering GPCR signaling pathways with RASSLs
We are creating families of designer G protein–coupled receptors (GPCRs) to allow for precise spatiotemporal control of GPCR signaling in vivo. These engineered GPCRs, called receptors activated… Expand
The Cytoplasmic Tail of the G-protein-coupled Receptor for Parathyroid Hormone and Parathyroid Hormone-related Protein Contains Positive and Negative Signals for Endocytosis (*)
The present studies were done to evaluate the role of the cytoplasmic tail of the G-protein-coupled receptor for parathyroid hormone (PTH) and PTH-related protein (PTHrP) in the endocytosis of… Expand
Conditional expression of a Gi-coupled receptor in osteoblasts results in trabecular osteopenia.
G protein-coupled receptors (GPCRs) coupled to activation of Gs, such as the PTH1 receptor (PTH1R), have long been known to regulate skeletal function and homeostasis. However, the role of GPCRs… Expand

In some G protein-coupled receptors (GPCRs), agonist-dependent phosphorylation by specific GPCR kinases (GRKs) is an important mediator of receptor desensitization and endocytosis. Phosphorylation… Expand
Human renal carcinoma cells produce hypercalcemia in the nude mouse and a novel protein recognized by parathyroid hormone receptors.
When grown in nude mice, cultured renal carcinoma cells from a hypercalcemic patient produced marked hypercalcemia that was reversed by resection of tumor. Conditioned medium from this cell line… Expand
