Radiation-induced GEPs in immortalized and primary breast cells


ABSTRACT: Today, Radiation therapy (RT) regimens are often used for many types of cancer including breast cancer (BC) disease. BC is an heterogeneous disease, at both clinical and molecular levels, presenting distinct subtypes associated with different clinical outcomes. This variability response may be caused by some factors linked to radiation or dependent to BC specific features such as tumor stage and hormone receptor (HR) status. We analyze and compare molecular responses, in term of gene expression profile (GEP) changes, induced by 9 and 23Gy of ionizing radiation (IR) in immortalized and primary cell cultures grouped according their Estrogen (ER) and Progesteron (PR) receptors positive or negative expression. Our explorative study gives some comprehensive hallmarks of the effects of the irradiation in BC cells. We trust that this study could have a role in driving RT towards personalised treatments, based also on the molecular characterization in BC.
