IGF-1 research in Canada investigates the anabolic, growth-promoting, and insulin-sensitizing properties of insulin-like growth factor 1, the primary mediator of growth hormone action. IGF-1 is a 70-amino acid single-chain polypeptide produced primarily by the liver in response to GH signalling via the JAK-STAT5 pathway. It signals through the IGF-1 receptor (IGF-1R), a receptor tyrosine kinase, to activate PI3K/AKT/mTOR and RAS/MAPK pathways. Canadian researchers study standard IGF-1 alongside the splice variant IGF-1 LR3 and mechano growth factor (MGF) to understand IGF-1 system biology.
GH/IGF-1 Axis Research
The GH/IGF-1 axis is the primary endocrine system controlling linear growth and body composition. GH stimulates hepatic IGF-1 production; IGF-1 then feeds back to suppress GH secretion and acts on target tissues to promote protein synthesis, cell proliferation, and survival. Canadian growth biology researchers study IGF-1 to understand this axis and how pharmacological manipulation of GH secretagogues ultimately translates to IGF-1-mediated anabolic signalling.
Muscle Protein Synthesis Research
IGF-1R activation in skeletal muscle activates the PI3K-AKT-mTORC1 pathway, which promotes protein synthesis by activating S6K1 and inhibiting 4EBP1. Canadian muscle biology researchers use IGF-1 to study mTOR-dependent muscle anabolic signalling and satellite cell biology in cell culture and animal models.
Sourcing IGF-1 in Canada
Research-grade IGF-1 (standard form) is available in Canada from EhBuddy Peptides. Lab-tested for purity. For laboratory research use only.
IGF-1 is the cornerstone anabolic signalling molecule for Canadian growth factor and muscle biology researchers, essential for understanding the GH/IGF-1 axis from pituitary to peripheral tissue.
