IGF-1 LR3 (Insulin-like Growth Factor-1 Long Arg3) is a synthetic peptide analog of endogenous IGF-1, modified to increase its stability and potency in experimental models. Here’s how it functions:
IGF-1 Mimicry: IGF-1 LR3 acts similarly to endogenous IGF-1 by binding to the IGF-1 receptor (IGF1R), a cell surface receptor involved in growth and repair signaling in research subjects.
Receptor Activation: Upon binding, it activates intracellular signaling pathways, particularly the PI3K/Akt and MAPK pathways, which are crucial in regulating cellular growth, survival, and protein synthesis during laboratory trials.
