As expected, FGF1 induced phosphorylation of FRS2alpha, ERK1/2 and PLCgamma1 in normal urothelial cells over-expressing wildtype FGFR3 (Figure 4b). Consistent with their complete ligand-independence, FGF1 treatment faile
[Paragraph-level] PMCID: PMC2789045 Section: RESULTS PassageIndex: 20
Evidence Type(s): Functional, Oncogenic
Justification: Functional: The passage discusses how the K652E, S249C, and Y375C mutations alter the signaling response to FGF1 treatment, indicating that these variants affect molecular function related to phosphorylation and activation of signaling pathways. Oncogenic: The context of the mutations being discussed in relation to their effects on signaling pathways suggests that they may contribute to tumor development or progression, particularly given the focus on their responses in cancer-related cellular contexts.
