Light sensitivity: Protect from direct light
Together they produce a larger, synergistic GH pulse than either alone
The primary GH pulse occurs during stage 3 deep sleep, and if sleep architecture is disrupted by hot flashes, night sweats, or anxiety, the GH response to secretagogues is blunted
PI3K/Akt/mTOR and MAPK/ERK Pathway Activation In research settings, IGF-1 LR3 activates the PI3K/Akt pathway (involved in survival, glucose metabolism, and protein synthesis), the RAS/MAPK pathway (regulating growth and differentiation), the mTOR pathway (governing anabolic protein synthesis signalling), and IRS-1/2 cross-talk with insulin receptor signalling the full complement of IGF-1R-mediated downstream effects
It comprises smooth muscles, cardiac muscles, and skeletal muscles
