To correlate levels of MnSOD, NFkβ, collagen 1a, and Brd4 RNA transcripts with protein in post irradiation lungs, tissue was removed from groups of 5 C3H/HeNHsd and C57BL/6NHsd female mice irradiated to 20Gy to the thoracic cavity at day 2, day 75, and day 150. Western Blot analysis was then performed using antibodies, and analyzed for band densities as described in the methods and in (Kalash et al. 2013a). Quantitative analysis of densitometry is in Table 5.
