Gene expression profiling induced by high dose ionizing radiation on MDA-MB-231 cells


ABSTRACT: Radiation therapy (RT) remains a vital component of the curative multimodality therapy for many types of cancer including breast cancer (BC). Even if great number of BC patients receive RT, not all of them report benefits, due to radioresistance activation depending also by hormone receptor status. We analyze and compare molecular responses, in term of gene expression profile (GEP) changes, induced by high dose of Ionizing Radiation (IR), in MDA-MB-231 with ER-/PR-HER2- receptor status. Moreover, we selected a MDA-MB-231 Radioresistent Cell Fraction (RCF), in which we highlighted specific molecules able to drive radioresistance. We trust that this study could have a role in the evaluating of RT response in term of radioresistance process activation to define a personalized biological-driven treatment plan in triple negative BC.
