Differences in L1, B1 and IAP repeat element methylation levels between age-matched untreated mice and mice aged 17–19 months at 420 days following irradiation with sham and 10 mGy X-rays.

<p>The NTS of L1, B1 and IAP repeat elements in the spleen (A–C) and liver (D–F) tissues of the 17–19 month old mice remaining 420 days following irradiation with sham (white; <i>n</i> = 17) or 10 mGy (light grey; <i>n</i> = 15) X-rays were compared to a cohort of untreated 17–19 month old mice (dark grey; <i>n</i> = 7). The NTS was assessed by high resolution melt following DNA extraction, bisulphite modification and amplification of repeat elements.
