What it is
Tesamorelin is a synthetic analog of growth hormone–releasing hormone (GHRH) engineered to improve stability and receptor selectivity for the GHRH receptor (GHRH-R).Research context
Used in vitro to interrogate somatotroph signaling via cAMP/PKA and phospholipase pathways, Tesamorelin helps model GH axis regulation at the pituitary level. It’s useful for mapping ligand–receptor dynamics, receptor desensitization, and biased signaling profiles compared with native GHRH and other secretagogues.Research relevance
Dissecting GHRH-R pharmacology and downstream GH/IGF-axis transcriptional programs.
Comparing receptor kinetics and stability versus native ligands.
Evaluating receptor coupling (Gs vs ancillary pathways) and feedback mechanisms in cell systems.
Common lab uses (examples)
Reporter assays (CRE-luc) for GHRH-R activation.
Time-course phosphorylation and transcriptomic profiling after stimulation.
Structure–activity relationship (SAR) benchmarking against other GHRH analogs.
