Targeting HGF c MET signaling to regulate the tumor microenvironment: Implications for counteracting tumor immune evasion Cell Communication and Signaling Springer Nature Link Dihexa MOL Changes HGF c Met pathway facilitates the perineural invasion of pancreatic cancer by activating the mTOR NGF axis Cell Death & Disease What if neuroplasticity research targeted the HGF c Met pathway? Dihexa (PNB 0408) is an angiotensin IVderived peptide studied in preclinical models for its role in synaptogenesis and cognitive signaling mechanisms. Human data remains limited.
