Aim 1: In the archived heart samples of fractionated proton and iron IR studies the study

plans to determine long-term IR-induced effects on cardiac fibrosis, inflammation, oxidative damage, microvascular, structural and morphological changes in the heart, including cellular hypertrophy and cytoskeletal reorganization.


Aim 2: In archived samples of CB6F1 mice irradiated with a range of low and very low doses of gamma, 14Si, 22Ti and 56Fe the study proposes to determine long-term effects and molecular endpoints in the heart as a function of IR type and dose.
