BT13 does not signal in the absence of RET. BT13 does not increase luciferase activity in reporter gene-based assay in cells expressing TrkA (A) and TrkB (B). BT13 does not stimulate TrkA (C) and TrkB (D) phosphorylation. BT13 does not promote activation of intracellular signaling cascades in cells expressing TrkA (E), TrkB (F) or parental cells lacking receptors for neurotrophic factors (G). IP, immunoprecipitation; G, GDNF; pY, phosphotyrosine; pAkt, phosphorylated form of Akt; pErk, phosphorylated forms of Erk1/2; GAPDH, glyceraldehyde 3-phosphate dehydrogenase, loading control.
