Pituitary Tumor-Derived Fibroblast Growth Factor Receptor 4 Isoform Disrupts Neural Cell-Adhesion Molecule/N-Cadherin Signaling to Diminish Cell Adhesiveness: A Mechanism Underlying Pituitary Neoplasia

Abstract excerpt

We previously identified pituitary tumor-derived fibroblast growth factor receptor 4 (ptd-FGFR4), an alternatively transcribed N-terminally truncated cytoplasmic receptor isoform. Unlike wild-type FGFR4, ptd-FGFR4 facilitates cell transformation and results in pituitary tumor formation in transgenic mice. To investigate differences in the tumorigenic properties of FGFR4 and ptd-FGFR4, we examined their abilities...
