Summary
Cinacalcet effectively lowers blood calcium and parathyroid hormone in patients with secondary hyperparathyroidism or parathyroid carcinoma. Chronic treatment demonstrates stable parathyroid hormone suppression, though long-term outcomes like bone health require further study.
Area of Science:
- Pharmacology
- Endocrinology
- Nephrology
Background:
- Secondary hyperparathyroidism and hypercalcemia are serious conditions.
- The parathyroid gland calcium-sensing receptor (CaR) plays a crucial role in calcium homeostasis.
- G protein-coupled receptors (GPCRs) are key targets for drug development.
Purpose of the Study:
- To evaluate the efficacy of cinacalcet in treating secondary hyperparathyroidism and hypercalcemia.
- To assess the impact of cinacalcet on blood calcium and parathyroid hormone levels.
- To review the therapeutic monitoring and long-term outcomes of cinacalcet treatment.
Main Methods:
- Cinacalcet allosterically modulates the parathyroid gland CaR.
- Oral administration of cinacalcet.
- Monitoring of serum calcium and parathyroid hormone levels.
Main Results:
- Cinacalcet administration leads to a decline in blood calcium and parathyroid hormone levels.
- Stable suppression of parathyroid hormone was observed during chronic treatment in clinical trials.
- Approved for secondary hyperparathyroidism in end-stage renal disease patients on hemodialysis and hypercalcemia in parathyroid carcinoma.
Conclusions:
- Cinacalcet is an effective treatment for specific hyperparathyroid and hypercalcemic conditions.
- Therapeutic monitoring of calcium and parathyroid hormone is essential.
- Further research is needed to evaluate the long-term clinical outcomes, including bone mass and fracture risk.

01:16Calmodulin-dependent Signaling
Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...

01:30Ligand-Gated Ion Channel Receptor: Gating Mechanism
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...
01:27Feedback Regulation of Calcium Concentration
Calcium is an essential signaling molecule required for various cellular functions. Calcium pumps and ion channels on cell and organellar membranes, such as those on the endoplasmic reticulum (ER), regulate calcium concentrations inside the cell. They remain closed, keeping the cytosolic calcium levels low at a resting state.
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...

01:08Allosteric Regulation
Allosteric regulation of enzymes occurs when the binding of an effector molecule to a site that is different from the active site causes a change in the enzymatic activity. This alternate site is called an allosteric site, and an enzyme can contain more than one of these sites. Allosteric regulation can either be positive or negative, resulting in an increase or decrease in enzyme activity. Most enzymes that display allosteric regulation are metabolic enzymes involved in the degradation or...

01:09GPCRs Regulate Adenylyl Cylase Activity
Some GPCRs transmit signals through adenylyl cyclase (AC), a transmembrane enzyme. AC helps synthesize second messenger cyclic adenosine monophosphate (cAMP). AC catalyzes cyclization reaction and converts ATP to cAMP by releasing a pyrophosphate. The pyrophosphate is further hydrolyzed to phosphate by the enzyme pyrophosphatase, which drives cAMP synthesis to completion. However, cAMP is rapidly degraded to 5′ AMP by the enzymes phosphodiesterase (PDE), preventing overstimulation of cells.
