Cross-Talk Between EGFR and IGF1R Influences the Response to RTK Inhibitors in Bronchopulmonary (BP)-NET Cell Lines

#1462

Introduction: BP-NETs represent ~30% of all neuroendocrine tumors. BP-NET treatment is challenging due to onset of resistance to chemo and targeted therapies. EGFR and IGF1R had been associated with tumor onset and progression in several neoplasia.

Aim(s): To investigate the role of EGFR and IGF1R and their possible cross-talk in BP-NET cells.

Materials and methods: Receptors expression was evaluated by Western blot in 2 BP-NET cell lines (NCI-H720, NCI-H727 cells). Cell viability and apoptosis were measured by ATPlite assay and Caspase3/7 assay, respectively. IGF1R and EGFR heterodimer formation was evaluated by immunoprecipitation (IP).
