DESCRIPTION
Signal transduction peptides are used in RUO studies to explore how cells send and receive messages. These signals help control how cells grow, repair themselves, and respond to stress. Researchers use these peptides in lab models to better understand how communication inside cells works—and what happens when it doesn’t.
Exciting Areas of Study
-
How cellular signals initiate chain reactions in lab models.
-
Peptide effects on messaging pathways like MAPK & PI3K.
-
How cells respond to stress in lab models.
-
Model disrupted signaling seen in pre-clinical disease research.
Research Applications
-
Map how cell signals change under different conditions
-
Test how peptides influence key response pathways
-
Study how signaling balance affects cell behavior over time
-
Tesamorelin is an N-terminally modified GHRH(1-44) analog used in RUO signal-transduction models to interrogate GPCR-driven cAMP/PKA signaling and CREB-linked transcription. Studies often quantify receptor engagement, second messengers, and downstream gene expression. Not intended for diagnostic or therapeutic use.
-
GHRH-R coupling and cAMP kinetics
-
PKA/CREB pathway transcriptional readouts
